Statement of the Problem In light of the widespread acceptance of the Minnesota Multiphasic Personality Inventory as a measure of various personality variables for people in many diverse settings, it is surprising that until several years ago there was no abbreviated form of the MMPI from which the standard scale scores could be reliably predicted. There is a great deal of clinical and research value in such an instrument. Often in clinical settings, it is difficult to persuade subjects to complete either the individual or group form of the MMPI. The length of the standard inventory makes it tedious for subjects to fill out, and some are unwilling or unable to devote the time and concentration that is required. In similar circumstances, many of the same people would agree to answer a shorter set of questions taken from statements on the longer standard MMPI. At times, there may be a need for rapid evaluation and communication of results, such as for consultation purposes or speedy classification of patients in a hospital or clinic. In addition to applied uses, a short version of the MMPI would expedite and simplify personality research. 1 A short form 2 could make it much easier to recruit subjects who may be unwilling to devote the time necessary to complete the long form. An abbreviated test could also reduce expenses and increase efficiency in both clinical and research settings by decreasing the amount of time spent in scoring and interpretation on the part of professional personnel. Kincannon (1968) developed the first short form of the MMPI which accurately predicted the standard scale scores. This version does not include clinical scales 5 and 0. Mini-Mult. All other basic scales are included on Kincannon's Evidence from studies which will be discussed in the following pages has shown that the clinical utility of the short version is limited in scope. Research indi- cates that the Mini-Mult enjoys variable success, depending on the population it is used with, and the amount of clinical information one attempts to extract from the scores. Therefore, by using the Mini-Mult on an optimal population for a limited purpose of general diagnostic classification, it may be possible to delineate a specific, valid, clinical use for the Mini-Mult. Several advantages of the short form have already been mentioned. If the Mini-Mult is able to provide reasonably accurate discrimination between psychotics and neurotics, mental health officials could begin appropriate intervention without waiting for more complicated and time consuming assessment procedures to be completed. The oral 3 form of the Mini-Mult will allow testing of illiterate subjects. It may also reduce the necessity for lengthy observation periods before treatment is initiated. B. Purpose of the Study Methods of psychological and psychiatric intervention may be influenced by psychological assessment of the problems to be dealt with. Assessment may take the form of interviews, behavioral observations, evaluation of psychological tests, examination of historical data provided by significant others, or professionals or agencies consulted by the individual in the past. a combination of two or more of these. It may involve Intervention can also be influenced by the results of histological, logical, or neurological tests. sero- Inferences drawn from various assessment techniques may be interpreted on three levels, depending on the individual clinician's theoretical bias, and on the questions he wishes to answer with assessment procedures. On the lowest level, the information about the client is directly related to the decisions to be made. An example would be the inference made by a college official after looking at a potential student's entrance test score. A decision to accept or reject the candidate is based on the score. The inference drawn must be either that the candidate is qualified, or that he is not. On the 4 second level, inferences may be descriptive generalizations and/or hypothetical constructs concerning the client. The third level inferences are similar to those at level two, varying only in complexity. In other words, assessment procedures are more involved in an attempt to learn as much about the client as possible. The goal is to develop a clear, complete representation of the client, and his behavior patterns. Intervention techniques may include chemotherapy, milieu therapy, electro-convulsive therapy, and psycho- therapies based on various theoretical viewpoints of abnormal behavior. also widely used. personal, Behavior modification techniques are Various levels of intervention include family, small group, organization, and community. The specific type of therapy may depend on the nature of the problem and on the therapist's decision to treat the symptoms observed, or the underlying causes. This decision is affected by the therapist's bias and is limited by his specific areas of competency. Therapeutic goals may be restricted by available facilities and/or priorities held by different agencies. A client's treatment can also depend on his financial and emotional resources, well as his intellectual abilities, as educational background, and cultural milieu. In a state hospital setting, intervention procedures usually depend mainly on the initial diagnosis. If a 5 patient has a record of previous hospitalization, affect the decisions made about him. that may Initial decisions in such settings include consideration of: hospitalzation vs. non-hospitalization, use of anti-psychotic drugs vs. other or no drugs, use of ECT vs. no ECT, and whether patient is suicidal or non-suicidal, etc. The purpose of this study is to evaluate a method of assessment which may be used to classify people for psychological or psychiatric purposes. The assessment procedure under investigation is a mathematical interpretation of MMPI scores which allows the tester to make a lower level inference about the test subject. By applying a simple additive formula, one is able to discriminate a psychotic person from a neurotic person, on the basis of scale scores combined in a linear fashion. This linear combination of scores is known as Goldberg's index. A subject whose index falls above a certain cutoff score is classified as psychotic. If the index is below the cutoff score, the subject is classified as neurotic. C. Review of the Literature The Minnesota Multiphasic Personality Inventory, of MMPI, has long been used to make decisions in problems of differential diagnosis in various settings. Meehl (1946) proposed a set of rules for making such decisions, which were based on configural properties of MMPI profiles. 6 His effort was one of the first attempts to set explicit rules for making specific diagnostic decisions. In this study he evaluated the MMPI for use in differential diagnosis of psychosis, psychoneurosis, and "conduct disorder." He found that a set of rules could be used to arrive at a diagnosis with greater success than a simple examination of high point scales would allow. More recently, Meehl and Dahlstrom (1960) developed a more effective set of rules for discriminating psychotic from neurotic profiles. Profiles which could not be classified as psychotic or neurotic were designated as "indeterminate." Henrichs (1964) attempted to derive a rule to extend the applicability of the Meehl and Dahlstrom results. He was unable to come up with rules which allowed a hit rate exceeding 50% for the new classification of "character disorder." The new classification could not be made with the same degree of accuracy possible with the rules for diagnosis for the other general categories. Although the hit rate is high, it has little clinical promise. Schmidt (1945) found that by analyzing MMPI profiles, differential diagnoses for major clinical classifications could be made with statistical significance. The major diagnostic groups in this study were inadequate personality, sexual psychopathy, mild psychoneurosis, neurosis, and psychosis. severe psycho- Hovey (1949) compared three psychoneurotic groups on the basis of profiles. He 7 discovered that the dissociative-conversion group produced a relatively consistent pattern, while patterns produced by anxiety and somatization groups were less consistent. Guthrie (1950) discovered that a high degree of diagnostic accuracy could be achieved by examination of code types. He used six profile patterns reported by Gough (1946) and Schmidt (1945). The diagnostic groups were anxiety state, inadequate personality, psychopathic personality, paranoia, depression, and mania. Leverenz (1943) found significant agreement between diagnoses made from MMPI profile patterns and psychiatric diagnoses made without the benefit of MMPI results. He obtained the highest agreement on the following groups: psychoneurosis, hypochondriacal type, depression, and psychosis. The investigation was made to evaluate the usefulness of the MMPI in a hospital setting. Modlin (1947) conducted a study along similar lines to examine the utility of the MMPI in clinical practice. He concluded that the test is a valuable psychometric tool in clinical psychiatric practice, but that test interpretation should be made in terms of the total clinical picture to prevent avoidable errors. The studies above are representative of the research dealing with the diagnostic capabilities of the MMPI. In general, previous research has shown the MMPI to be a worthy aid in making differential diagnoses. not a substitute for the clinician, however. It is 8 Beside diagnostics, the MMPI has been put to a great number of uses. Peterson (1954) investigated its ability to predict hospitalization of psychiatric outpatients. He concluded that the MMPI could make correct predictions approximately two-thirds of the time. Farberow (1950) used the MMPI to study personality patterns among hospitalized suicidal patients. The inventory has also been used to study personality characteristics of other groups including college students nurses (Goodstein, 1945b; Bier, 1948), (Weisgerber, 1954; Hovey, medical patients 1953), non-psychiatric (Weiner, 1948; Anderson and Hanvik, 1950; Ganter, 1951; Hanvik, 1951; and many others). The MMPI, it seems, can be viewed as a double-edged sword in the hands of ,a psychometrist, serving both clinical and research needs. There are several possible arguments against the development of an abbreviated MMPI. One is that a short form is generally considered to be less reliable than the longer form of a test which is also likely to have greater validity. formula. This view is demonstrated in the Spearman-Brown However, this formula is effective for tests in which all items are assumed to be more or less equivalent. In his discussion of this topic, Kincannon (1968) cites at least twelve references which report on the variances of different MMPI scales. He concludes that the various scales of the MMPI are very heterogeneous. Since items 9 are assumed to be equivalent, any deletions from a long test would be considered to be random. This does not have to be the case. Kincannon (1968) followed this line of reasoning in the development of the Mini-Mult, a 71 item abbreviation He derived the inventory by clustering items of the MMPI. in each scale. The clusters were based on data obtained Clusters were groups of by Comrey (Kincannon, 1968). items, each having a phi coefficient of .30 or above with the other items in the group. taken from each cluster. Next, several items were Usually, these items were the ones scored on the greatest number of scales. In this way, the item pool was reduced first to 288 and finally to 71 items. Scales duplicated on the Mini-Mult include all the validity and clinical scales except Mf and Si. Kincannon ran two comparisons of the MMPI and the Mini-Mult, which was extracted from the MMPI results, on two groups of subjects. One was a group of psychiatric inpatients at a general hospital. The other was a group of patients at a community mental health center. In each case, the average correlation between raw scale scores was .87. Next, he investigated the functioning of the Mini-Mult as he intended it to be used in a clinical situation. First a standard MMPI was administered to each of 30 male and 30 female patients in a psychiatric hospital. On the following day, half the subjects completed a retest 10 of the standard MMPI, while the other half completed the Mini-Mult. Then on the third day, this procedure was reversed, and finally, each patient had finished two standard MMPI's and a Mini-Mult. Kincannon obtained scores on each of these tests and extracted Mini-Mult scores from the first standard MMPI results. Analysis of the results suggests that the Mini-Mult underestimates extreme elevations of scales F and Ma. Kincannon correlated scale scores from each test with those from each of the other tests. He also compared MMPI scale scores with reliability estimates made with the Spearman-Brown to discover if the Mini-Mult compared favorably with the formula estimates of its predictive ability. For every scale, he found that the reliability of the Mini-Mult was superior to that predicted by the Spearman-Brown formula. He found a mean error of 14% in prediction of MMPI scale scores from the Mini-Mult, which was half the average error predicted by the formula. In response to arguments that such correlations between short and long forms actually underestimate errors in classification made by short forms of various tests (Kramer and Francis, 1965; Mumpower, 1964; Silverstein, 1965), Kincannon made comparisons of the decisions based on scores from the two forms. Such decisions are commonly made by examining code types or profiles of the results. Kincannon made two investigations to determine the degree 11 of correspondence of code types between the two forms. Again, the results indicated that the Mini-Mult was a good predictor with only a 14% loss in correspondence to results found with test-retest administrations of the standard MMPI. Kincannon concluded that the Mini-Mult was a useful substitute for the MMPI in psychiatric hospital settings. In an attempt to cross validate his findings, Lacks (1970) administered the MMPI to a group of psychiatric inpatients. She extracted Mini-Mult scores from the MMPI data and correlated the scaled scores, finding results similar to those reported by Kincannon. She also compared the two forms on the basis of decisions made by examining clinical code types reported by Haertzen and Hill (1959), and found no significant differences. Armentrout and Rouzer (1970) found a high correspondence between scales for both forms in a study of delinquent adolescents. Comparisons of high point codes between the two forms indicated that the Mini-Mult is not a good diagnostic tool for this type of population. Their findings were comparable to those of Henrichs (1964), who attempted to develop rules for spotting character disorders. Subjects with character disorders and delinquents have similar profiles. If the results of Armentrout and Rouzer are examined with this in mind, it can be assumed that their results do not directly challenge the 12 comparability of the MMPI and the Mini-Mult since Henrichs showed the weakness of the MMPI itself as a diagnostic aid with this type of population. Armentrout (1970) compared scores obtained by college students in a correlational study of the two forms, with results similar to those discovered by Armentrout and Rouzer (1970). Correlations of scales were significant, but no equivalent to those found by Kincannon (1968). Harford, et al. (1972) discovered significant correlations between scales on the two forms for a group of psychiatric outpatients. They extracted the Mini-Mult from the standard MMPI, as did Lacks of code types (Haertzen and Hill, resulted in a 50% match. (1970). 1959) Comparison on the two forms, Application of rules for discrimination of psychotic from neurotic profiles (Meehl and Dahlstrom, 1960),resulted in a 35% match on the long and short forms. These findings suggest that the Mini-Mult is a less accurate predictor of the MMPI for an outpatient group than it appeared to be for Kincannon' s inpatient sample. These conclusions are consistent with those drawn by Armentrout and Rouzer et al. (1970). Harford, suggest that difference among the findings of various Mini-Mult researchers may be a function of the degree or severity of the disorders found in the populations sampled. To investigate this possibility, they divided their sample into more and less severe groups, using F 13 A comparison scale scores as a measure of severity. of the two forms in terms of clinical code types, resulted in a significantly higher number of matches in the more severe group. Gaylon and Wilson (1971) compared MMPI and extracted Mini-Mult scores of a sample of children in a child They found high correlations between guidance clinic. scales, but profile comparisons resulted in classification errors one-third of the time. They suggest that the Mini-Mult may be of some value as a screening instrument in some settings. Adequate caution in interpreting results would have to be exercised; however, since misclassifi- cation would be an ever-present pitfall. Newton (1971) checked the Mini-Mult in a study of hospitalized male alcoholic patients. He found smaller correlations between scales than Kincannon (1968) did. His results also confirmed a conclusion drawn by Kincannon in his study. They both found that when the same forms or both forms are administered within a short period of time, the results on the second protocol portray subjects in a more socially desirable light. Hartman and Robertson (1972) studied a sample of patients in a community mental health agency. They administered the MMPI and the Mini-Mult on an alternating basis, and a Mini-Mult was also extracted from the standard MMPI. They found significant correlations 14 among all scales on all three tests. However, they learned that the Mini-Mults understimated scales F, Ma, and Pa significantly, When the MMPI was compared with the Mini-Mult in terms of profile code types, it was dis- covered that for general diagnostic categories psychotic, neurotic, personality disorder, normal) (e.g., essentially the two forms agreed in 77% of the male cases and in 50% of the female cases, for a combined agreement of 63%. Hartman and Robertson speculate that this degree of correspondence is not high because decisions about matches are based on the highest scale of each code type. If "correspondence" is defined as elevations of the same scales on both profiles, there may be more agreement than these data reveal, since similar profiles do not always have the same high point. Essentially, the Mini-Mult seems to be almost as effective as a MMPI substitute in a community mental health agency as in a psychiatric hospital. Palmer (1973) studied a sample of 30 male and 30 female psychiatric inpatients at the Toledo State Hospital. They were selected without regard to any independent evaluation of their psychiatric diagnoses. Each subject was administered the MMPI and then the Mini-Mult on consecutive days. Order of administration was random, with half the subjects taking the MMPI first. was reversed for the other group. The order Palmer used the written 15 statement form of the Mini-Mult. He learned that neither order of administration nor sex of the subject had significant effects on the findings. Scale correlations were all significant at the .01 level except the F scale. Palmer evaluated diagnostic reliabiilty by comparing 3-point codes on the two tests. extremely low. (Lichtenstein and Bryan, 1966) Agreement between the code types was He also determined that the median percent of agreement between the Ss' responses to homologous items on the two tests was 83%, with a range from 59% to 98%. Palmer concludes that the data do not support the use of the Mini-Mult for state hospital patients. Although scale correlations were significant between the tests, their magnitudes were rather low. The Mini-Mult failed to provide the same diagnoses that the MMPI did when processed with 3-point code types. Palmer suggests that the subjects' inconsistent response patterns may reflect unreliability of the population being studied instead of an unreliable instrument. There is a plethora of techniques which have been developed for arriving at a diagnosis from the MMPI profile. Goldberg (1965) compared nearly all these techniques or diagnostic signs in an effort to determine how accurately they predicted a diagnosis of psychotic versus neurotic from the MMPI. After examining his results, Goldberg selected the five scales which had the highest 16 beta weights in a linear regression equation. Then he combined them in a simple non-weighted linear composite of scores. The new index (CL + Pa + Sc - Hy - Pt) had a validity coefficient greater than any of the previous diagnostic signs used to discriminate psychosis from neurosis. Goldberg drew his data from the 1959 MMPI study of Paul Meehl where there was an unspecified amount of criterion contamination in the sample group. Subjects were 861 male psychiatric patients. Goldberg (1969) cites several other ways of attempting to solve this diagnostic problem. perceptron algorithm procedures These include the (Rosenblatt, 1958), density estimation (Hoffman, 1968), and Bayesian algorithms, none of which result in validity coefficient exceeding the validity obtained with the simple linear combination. He also reviews the work done with moderator variables for the linear combination. Ghiselli (1956, 1960, 1963) and Saunders (1956) identified moderator variables which appeared to enhance prediction when applied to certain diagnostic signs. The best single scale moderator was the K scale score. Prediction was improved for low K scale scores. The best multiscale moderator was found to be a linear combination of six scales (D + Pd + Sc - F - Hs - Pa). Low scores on this variable improved prediction when applied to certain diagnostic signs. Overall, however, prediction was improved insignificantly. 17 In another investigation similar to Goldberg's (1965), using large samples and relatively clear criteria, Stilson and Astrup (1966) reported that improved predictions found through the use of non-linear procedures are lost in cross validation. In an effort to highlight the value of diagnoses made by statistical methods, Goldberg (1968) cites 10 studies which indicate that the amount of professional training and experience of a human judge or diagnostician has no bearing on his diagnostic accuracy. In addition, he cites a number of similar investigations which suggest that the amount of information available to the diagnostician is unrelated to the accuracy of his resulting inferences. It seems that clinical judgments tend to be unreliable in terms of consensus and convergent reliability. Convergent reliability is the reliability of different judges using different sources of data on the same patient. Clinical judgments appear to be minimally related to the experience and amount of data available to the judge. Goldberg also concludes that clinical judgments are rather low in validity on an absolute basis. Goldberg (1965) compared the validity of 29 clinical psychologists with the validity of the linear model to find out whether human judges were more accurate in discriminating psychosis from neurosis on the basis of 18 MMPI profiles alone. His results were consistent with those mentioned above. The model was more accurate than the judges themselves. Goldberg (1972) cites other research with similar findings in related fields. In all the cases he discusses, a linear statistical model has proven to be superior to man. He concludes that no research in print has proven man to be a better predictor of various criteria than a simple linear statistical model. The job of psychometricians in the area of psychodiagnostics has been to find a statistical method which most nearly represents the cognitive processes engaged in by the clinician. Goldberg's psychotic-neurotic index has proven to be equal or superior to both human judges and configural models as a discriminator between psychotic and neurotic MMPI profiles in virtually every case. In another study, Goldberg (1972) attempted to classify group rather than individual profiles by utilization of several linear indexes. Goldberg used group MMPI profiles from over 200 groups including various normal, psychiatric, and sociopathic classifications. The sex of individual group members was male, female, or mixed, depending on which group they belonged to. Goldberg introduced linear models similar to his psychotic-neurotic index for discrimination between "normal" and "deviant" profiles, as well as between "psychiatric" and "sociopathic" profiles. 19 The criteria used to judge the success of these indexes were the diagnoses applied to the group profiles by Goldberg's collaborators, who developed them from samples of homogenous individual profiles. Analysis of results demonstrated that application of the psychotic-neurotic index to group profiles was accurate in 93% of the cases. Extreme accuracy found with this and other linear models led Goldberg to conclude that scales and equations constructed on individual profile data may be very potent when applied to group profiles. It appears that basic processes unique to various generally classified groups tend to be magnified when group profiles are analyzed. Hartman and Robertson (1972) suggested possible reasons for difficulties in obtaining adequate diagnostic agreement between the MMPI and the Mini-Mult, when configural models are used. Gynther, Altman, and Sletten (1963) have identified a set of two-point code types and designated the correlates which are significantly related to them. One feature of two-point code types is that they do not depend on a third scale, which is less likely to remain constant on different profiles produced by the same subject. In other words, two MMPI profiles of the same person are more likely to agree (even by chance) on a tentative diagnosis or personality description. Gynther, et al., have found that reciprocal two-point code types, such as 2-1/1-2, have the same correlates in almost all cases. 20 Hoffman and Butcher (1975) used two-point code types (Gynther, Altman, and Sletten, 1973), points, high F scales as well as high scale (T > 100), and other configural codes in a study of the clinical limitations of three abbreviated versions of the MMPI, including the MiniMult. nosis. They found a wide range of hit rates for psychodiagEach version predicted with different hit rates for each MMPI configural pattern. No short form consistently predicted MMPI diagnoses for all code types better than the other forms. Each form worked better than the others for several configuration patterns. None of the three short forms were found to predict configural patterns well enough to be used in a broad clinical situation. These authors point out that the MMPI is a psychological tool with a tremendous number of practical uses. They also suggest that if clinical goals are limited, certain instruments which are valid for limited purposes may be valuable. Hoffman and Butcher go on to cite a recent article (Overall, Butcher, and Hunter, 1975) in which the authors report a high degree of success with a discriminant function (unspecified) which seems to accurately differentiate broad diagnostic categories, when applied to Dean's 168 item version of the MMPI. (1973) D. Rationale In the preceding sections of this chapter, the foundations for the present study have been described. This investigation will attempt to determine the feasibility of applying Goldberg's psychotic-neurotic index to scores obtained on the Mini-Mult, an abbreviated version of the MMPI, for comparable diagnostic classification of patients in a state psychiatric hospital. A high degree of agreement between Goldberg-MMPI diagnoses and Goldberg-Mini-Mult (oral) diagnoses would illustrate the diagnostic capability of the Mini-Mult, when processed with Goldberg's index. It is hypothesized that the Mini-Mult can be used to discriminate psychosis from neurosis as well as does the MMPI. One reason that Goldberg's rule may be particularly effective in this study involves the specific scales it employs. Scales that the Mini-Mult appears to consistently underestimate are not used to compute Goldberg's index. In conjuction with the Goldberg comparison, correlations between scales for each form of the test will be determined to find out how well the Mini-Mult is able to predict the standard scale scores. Profile high points will also be compared, as well as two-point codes identified by Gynther, et al. (1973). Obviously, the success of all these methods 21 22 of comparison will depend, to some degree, on the correlation coefficients found between scales on the tests. The two-point codes will be used because this method of comparison eliminates, for nearly all practical purposes, the drawbacks to configural comparisons which Hartman and Robertson (1972) recognized. The techniques used in this study were chosen for their demonstrated superiority over some of those used in previous investigations of the Mini-Mult. The psychi- atric population was chosen because previous studies have shown that correlations between MMPI and Mini-Mult scales are consistently higher for populations with more severe mental disorders. An important point to keep in mind is that the main point of this research is the determination of the applicability of Goldberg's psychotic-neurotic index to the Mini-Mult. portance, accuracy Also of interest, but of lesser im- is a close look at the increased diagnostic (if any), or agreement between the MMPI and Mini-Mult, provided by the use of two-point, rather than three-point, code types for configural comparisons. It is hypothesized that scale to scale correlations will be highest in correlations of the first MMPI with the internal Mini-Mult, which will be extracted from the first MMPI, and of the two MMPI's. results. Kincannon (1968) found these Since the extracted Mini-Mult and the second MMPI can be considered primary estimates of reliability, 23 correlations between the first MMPI and the oral Mini-Mult should be lower than the correlations mentioned above. This relationship should also hold for high-point and twopoint code comparisons. It is further hypothesized that there will be no significant difference between MMPI and oral Mini-Mult classification decisions made by application of Goldberg's psychotic-neurotic index. It is hypothesized that the two-point codes will provide a higher degree of diagnostic agreement between the MMPI and the Mini-Mult than has been found with three-point code types. It is important to realize that this is a limited investigation of the clinical utility of the Mini-Mult. should not be construed as an inquiry into the full-scale clinical capability of the Mini-Mult. It CHAPTER II METHODS SECTION Instruments A. In order to examine the effectiveness of Goldberg's psychotic-neurotic index, two personality inventories were employed: The Minnesota Multiphasic Personality Inventory (MMPI, Form R) and the Mini-Mult (oral question form). The MMPI is a lengthy self-report inventory which is used to identify a number of outstanding personality characteristics. It consists of 566 statement items, of which approximately seven-tenths are ordinarily scored in clinical situations. Items are answered "true" or "false" on a separate answer sheet. Objectivity is an important feature of this instrument. It may be scored by machine or by the use of printed answer keys. The reliability and validity of the MMPI for a number of populations have been well documented by Welsh and Dahlstrom (1956). The Mini-Mult, an abbreviated form of the MMPI, which includes the validity and basic clinical scales, except scales 5 and 0, has been described in Chapter I of this text. The oral question version of the Mini-Mult was used here. The 71 question items are read aloud to 24 25 each subject by the examiner. Subjects respond vocally to indicate affirmative or negative answers. records all responses. scoring system. The examiner The Mini-Mult has an objective Each response is noted and tallied according to the scale or scales it happens to represent. varous constants developed by Kincannon Then (1968) are applied to each scale score so that Mini-Mult scores are comparable to ordinary MMPI scores. Various measures of reliability and validity for the Mini-Mult are documented in Chapter I of this paper. B. Subjects Subjects involved in this study were 30 male residents at the Austin State Hospital in Austin, Texas. The subject pool includes men from two geographic locations in Texas: Travis and Harris Counties.

Several other requirements limited the sampling process in this case. Hospital administration personnel allowed patients of four institutional units to serve as the population for this study.

The men in this sample represent the entire portion of the total male population which could be enlisted with the assistance of the hospital staff, while also meeting the subject criteria. The subjects have been hospitalized for periods ranging from a few days to almost 20 years. Twenty-four of the 30 subjects have records of between one and seven instances of hospitalization prior to the present one. Six subjects were in a psychiatric hospital for the first time, with no record of previous admissions. The sample group is comprised of a set of mixed neurotics and psychotics according to hospital diagnoses based on observation, interview, and case history data. C.

On the third day, the Each subject had completed two Form R MMPI's and an oral Mini-Mult, at this point. oral form was used in this study since that was the version used in Kincannon's original study. The 29 Patients were informed that they were participating in research which may benefit future hospital patients by changing some (nonspecific) admission procedures. Administration of the MMPI is not an ordinary admission procedure at this hospital. After the three forms of the scale had been administered and scored, all validity and clinical scale raw scores, excluding scales 5 and 0, were correlated between each form, and with raw scale scores obtained from an internal Mini-Mult extracted from the first administration of the MMPI. Correlations will be reported as Pearson Product Moment correlation coefficients.

CHAPTER III RESULTS From the three test administrations, scores were obtained, four sets of including the internal Mini-Mult extracted from the first administration of the standard MMPI. These were the first standard administration (Ml), the second standard administration administered oral Mini-Mult Mult (E).

In almost every case, the standard deviations of the Mini-Mults were smaller than those of the standard MMPI's. marked for scales F, The restriction in variablity was most 6, 8, and 9, suggesting that the Mini-Mult underestimates extreme elevations on those scales. The t tests for the various combinations of data sets showed statistically significant differences between the means for scales L, F, 3, 6, 7 and 8 on the M E comparison. Significant differences were also found 30 (Table 3) between 31 means for scales L, F, K, 6, 7, and 9 on the M1 0 comparison. In fact, significant differences were found for several scales (L, F, K, 6, 7, and 8 being most frequent) all comparisons with the sole exception of M 1 M 2 . for Even though correlations between comparable scales were significant in nearly all comparisons (Table 4), these differences between means of comparable scales were found. Also, while nearly all of the scale to scale correlations were significant, many were fairly low. Almost all of these correlations were lower than those found by Kincannon (1968) in his original research with the Mini-Mult. They were higher though, than similar correlation coefficients reported by Newton (1971), Armentrout and Rouzer (1970), and Armentrout (1970). The point of this study is to focus more on the decisions- made by interpretation of the tests, than to question the scale to scale correlations. Of course, this is affected by the comparability of the -scales, but the interest of this investigation is to evaluate the outcomes provided by use of each test. Table 5 illustrates the percentages of diagnostic agreement between various combinations of the two administrations of the two test forms. The use of Goldberg's index provides scores which are classified as psychotic or neurotic for each test protocol. Accordingly, Table 5 shows how much agreement was found between test forms for these classifications. Percentages 32 of diagnostic agreement were computed, also for high points and two-point codes. Goldberg's index was highly successful as a method of diagnosis in most cases. Goldberg's index classified 29 M, protocols as psychotic and one as neurotic. It classified 29 oral Mini-Mult protocols as psychotic and one as neurotic.' Goldberg's index classified 28 M2 protocols as psychotic and two as neurotic, while it lableled 18 of the extracted Mini-Mult protocols psychotic and 12 neurotic. The two administrations of the MMPI agreed on a general diagnosis made with Goldberg's index in 90% of the cases,While M, and E agreed on only 63% of the cases. Other comparisons involving the internal Mini-Mult resulted in relatively low percentages of agreement. Tests of significance of these percentages indicate no statistically significant differences in the diagnostic abilities (a la Goldberg) of the MMPI, and the oral Mini-Mult. Significant differences were found; however, in the Goldberg diagnostic abilities of the MMPI and the extracted Mini-Mult. These differences were present in the diagnostic abilities of the two Mini-Mults, also. These differences in percentages of agreement indicate that the oral MiniMult is a better diagnostic predictor of the MMPI than the extracted Mini-Mult, regardless of scale to scale corre- lations. Scale high-point comparisons were found to show less agreement than was possible by the use of Goldberg's 33 index. Comparisons of the standard forms and the Mini- Mults resulted in percentages of agreement which were comparable to percentages found by most other investigators, including Kincannon (1968), Armentrout and Rouzer and Hartman and Robertson (1972). (1970), The two-point codes were less successful than the high-point codes when percentages of agreement were calculated. Even so, the two-point codes provided higher agreement between the MMPI and the oral Mini-Mult with this psychiatric sample than Armentrout and Rouzer (1970) found when they used a similar method of profile analysis for a group of delinqpents. Gynther, Altman, and Sletten (1973) identify, along with two-point codes, a high F scale raw score (F > 25) with a set of replicated correlates. of agreement on this measure were as follows: 30%; M1 0 = 10%; M 1 E = 13%; M 2 E = 10%; M 2 0 - Percentages M1 M 2 = 7%; OE = 10%. The fact that these percentages are lower than those for high-points and two-point codes must be carefully considered. For example, these percentages represent agreement between test forms on only one scale, while the high-point percentages represent the occurrence of agreement on any one of several possible clinical scales. Table 6 shows correlation coefficients found for continuous scores on Goldberg's index for the various combinations of the test forms. Values of p included on the table signify that only the correlation coefficients 34 for the M 1 M 2 , M 1 E, and M 2 0 comparisons were statistically significant. This table, when compared with Table 5, reveals a possible complication involved in the dichotomy of psychotic-neurotic that Goldberg's index provides. For the M 1 M2 combination, the percentage of agreement was high and the correlation was significant. held true for the M 2 0 combination. The same The M1 0 combination had an insignificant correlation with a high percentage of agreement on Goldberg's index. This difference is probably, not necessarily, due to sampling error. A significant correlation coefficient with a low percentage of agreement is found in comparing the data for the M1 E combination on Tables 5 and 6. This is not what would be expected in view of the dramatic differences found between the oral Mini-Mult and the extracted internal Mini-Mult. It may be that the relatively high scale to scale correlations for the M 1 E comparison resulted in a significant correlation coefficient for the continuous Goldberg scores. diagnostic ability of the extracted Mini-Mult The poor (Table 5) seems to be a result of a drastically low mean score on Goldberg's index (Table 7). tests are quite a bit higher.

(1972) applied them to the Mini-Mult comparison with the MMPI. One point to keep in mind when considering the results discovered in this study is that approximately 83% of the subjects were psychotic according to hospital diagnoses. Research of this kind usually is based on a sample group divided (or groups) which is more evenly (i.e., 50% psychotic and 50% neurotic). This type of representative sample was difficult to obtain from the population being examined. Therefore, the results of this study should be applicable for similar populations. Generalization to different populations must be made with extreme care. 41 42 The Mini-Mult's tendency to underestimate extreme elevations of certain scales was not a problem in this study. Scales F and 9 are not employed in the computation of Goldberg's index. Apparently, the subjects in this psychiatric sample scored high enough on scales 6 and 8 of the Mini-Mults that any underestimates of the scores were unimportant. Indeed, the tendency of the Mini to underestimate scales 6 and 8 may be a result of sampling error, since Kincannon (1968) and Lacks (1970) failed to arrive at the same conclusion with their samples of psychiatric patients. It would be interesting to determine the actual degree of general (psychotic vs. neurotic) diagnostic accuracy allowed by the two-point codes for which Gynther, et al. (1973) found replicated correlates. However, it was prevented in this study by the sample size and by the nature of the replicated correlates. In many cases, a two-point code type is not labeled psychotic, or anything else. neurotic, The reason is that behavioral correlates are used rather than broad classification categories. Some code types can clearly be labeled "psychotic" or "neurotic" on the basis of the behavioral correlates. Others cannot be separated so easily. For limited clinical applicability in a psychiatric hospital, the oral form of the Mini-Mult appears to work as well as the standard MMPI. Its applicability is 43 restricted to simple discrimination between psychosis and neurosis in a population of hospitalized psychiatric patients. Since this is such a limited purpose, and since only six scales are involved in computation of Goldberg's index (for the discrimination), it seems reasonable to believe that the length of the Mini-Mult could be further reduced. Kincannon (1968) realized that changes in context might have a significant impact on the functioning of the scales of the Mini-Mult when compared with the MMPI. He cites several articles which indicate any differences in the functioning of the Mini-Mult scales are negligible. Therefore, it seems likely that an abbreviation of the oral Mini-Mult, which included only those questions found on scales L, 6, 8, 7, and 3 (scales used to compute Goldberg's index) would work as well as both the MMPI and the oral Mini-Mult as a diagnostic discriminator. Such an abbreviation would accomplish the same goal while further reducing the amount of time and effort required for administration and scoring. The abbreviation would be composed of 51 orally administered questions. The reduction in size compared to the oral question form of the Mini-Mult would be about 28%. An equal reduction of required time for administration and scoring would also be possible. The ability of Goldberg's index to discriminate between psychotic and neurotic profiles seems to work as well for the oral Mini-Mult as it does for the standard MMPI. 44 The abbreviated Mini-Mult, then, would be a selection of 51 MMPI statements (in oral question form) which could be used to discriminate psychosis from neurosis with as much accuracy as the MMPI itself, for populations of hospitalized psychiatric patients.
