A DIMENSIONAL ANALYSIS OF MMPI ITEMS

A method of analysis specifically designed for binary data was applied to 100 MMPI items. Sixty, items were carefully chosen to represent the nine major clinical scales with respect to direction of keying, social desirability scale value and endorsement frequency. The remaining 40 items were randomly chosen from items not appearing on any of these scales. Although a complete solution was obtained in five dimensions, only three were retained. The three dimensions were related to scale membership, gender of the respondent and various item characteristics. The results clearly support the two major MMPI factors obtained on a scale level and additionally show a strong gender dimension.     

RELATIONSHIPS BETWEEN RESPONSE STABILITY AND ITEM ENDORSEMENT,SOCIAL DESIRABILITY,AND AMBIGUITY IN THE MMPI AND THE CPI

Relationships between two indices of response stability and item endorsement, social desirability, and seven ambiguity indices were investigated separately within the MMPI, the unique items of the CPI, and two subpools moderate in endorsement and social desirability. Within the two original pools, zero-order correlations and multiple regression analyses revealed that only extremeness of endorsement and social desirability were substantially related to response stability; within the moderate subpools, however, indices of ambiguity-especially item length and ratings of global ambiguity, behavioral reference, and estimated stability-accounted for important degrees of variance individually as well as in combination. Reasons for the moderating effects of endorsement and social desirability are discussed, as are the implications for scale construction.     

Psychiatric Patients' Responses to MMPI Religion Items

Responses of Jewish and Protestant psychiatric Ss to 10 MMPI religion items were found to differ in the manner expected on the basis of Jewish and Protestant normals' ratings of the unfavorability of item endorsement. Education and private vs. public hospitalization were independently associated with item rejection rate. However, sex of S and psychotic vs. non-psychotic diagnosis were not related to item rejection. The differential response rate of Jewish and Protestant patients provides validity generalization for Gynther, Gray and Strauss' (1970) conclusion that social desirability values of MMPI items vary with relevant subject background characteristics as well as with item content.     

Social desirability and Wiggin's MMPI content scales.

Using the Minnesota Multiphasic Personality Inventory (MMPI) item pool, Wiggins (1966) developed 13 scales, each with a homogeneous content. The 13 scales, along with marker scales for the 1st 3 MMPI factors, Edward's social desirability (SD), Welsh's repression (R), and Wiggins's social desirability (Sd) respectively were scored in the MMPI. The same scales were scored in an Experimental Multiphasic Personality Inventory (EMPI). A principal-components analysis of the 16 scales when scored in the MMPI resulted in 4 factors. A principal-components analysis of these same scales when scored in the MMPI and when scored in the EMPI were found to be highly congruent. The SD, R, and Sd scales proved to be excellent markers for the 1st 3 factors of the MMPI and also for the 1st 3 factors of the EMPI. Results provide further evidence that the 1st MMPI factor is a social desirability factor rather than a content factor.     

Some properties of the ego-resiliency subtle scale of the MMPI.

The Ego Resiliency-Subtle (ER-S) scale was developed by Block (1965) as a social desirability free measure of the first factor of the MMPI. The purpose of the present experiments was to determine whether or not the 40-items comprising the ER-S scale remain neutral regarding social desirability and if the subject's score on the scale remains constant when taken out of the context of the other MMPI items; if so, the ER-S scale could be used as a screening device. Experiment I demonstrated that the items were not neutral regarding social desirability when taken out of context, but Experiment II indicated that this did not influence the responses subjects gave to the items. Because a memory factor may have been operating in Experiment II, a third experiment was conducted to minimize this factor resulting in a male-female vs. embedded-alone interaction and an order of presentation vs. embedded-alone interaction.     

MMPI Item Changes by College Students under Ideal-Self Response Set

This paper reports item changes when college students were asked to assume a set to the MMPI in which they answer as they “would like to be.” Accumulated evidence from several populations separated by a period of years and by culture background demonstrated a consensual profile. While weighted in the direction of social favorability, the group profile is distinguished by a theme of self-mastery in social situations. Item analysis indicated an area of idealized acceptance or rejection of items which has potential value in personality assessment. The findings also have implications for desirability as a factor in MMPI records and for the validity of “subtle” items.     

Predicting the Completion of an Integrative and Intensive Outpatient Chronic Pain Treatment With the Personality Assessment Inventory

The X-zero distinction has been used as the operational definition of MMPI item subtlety in previous research. A consistent finding has been that the X items, which are obvious in terms of pathological content, can be faked whereas the more subtle zero items cannot be faked. The present study examined the relationship between instructional sets and endorsement patterns, using a more refined, comprehensive measure of item subtlety. Sixty (30 male, 30 female) subjects completed two MMPI protocols, one under a standard instructional set and the other under either a fake-good or fake-bad response set. Order of administration and sex were counterbalanced. In general, the findings for the subtle-obvious dimension paralleled the previous findings with the X-zero distinction. Endorsement of obvious items was a direct function of instructional set, whereas endorsement of subtle items was inversely related to instructional set. Because subtle items did not appear to measure the constructs for which they had been originally intended, other uses for subtle items were discussed.     

Evaluating the Distorting Effects of Inattentive Responding and Social Desirability on Self‐Report Scales in Creativity and the Arts

Inattentiveness and social desirability might be particularly problematic for self‐report scales in creativity and arts research. Respondents who are inattentive or who present themselves favorably will score highly on scales that yield positively skewed distributions and that assess socially valued constructs, such as scales measuring creativity and arts knowledge. A total of 204 undergraduates completed an online survey with several self‐report measures (the Creative Achievement Questionnaire, the Biographical Inventory of Creative Behavior, and the Aesthetic Fluency Scale). Many metrics of inattentiveness were included, such as directed response items, self‐reported attentiveness, and scales to catch inconsistent and patterned responses. The Balanced Inventory of Desirable Responding measured facets of social desirability. We found high rates of inattentive responding. A latent class analysis indicated that around 25% of the sample was potentially inattentive, and inattentive respondents received higher scores on the creativity and arts scales. Excluding problematic participants increased the effect sizes of interest, consistent with the coarsening effect of careless participants. Social desirability, in contrast, had essentially no relationship with the creativity and arts scales. These findings suggest that social desirability is probably less of a problem than researchers fear, but that inattentiveness is an underappreciated threat. Some practical guidelines are suggested.     

A CONCEPTUAL AND EMPIRICAL REEXAMINATION OF THE MEASUREMENT OF THE SOCIAL DESIRABILITY OF ITEMS: IMPLICATIONS FOR DETECTING DESIRABLE RESPONSE STYLE AND SCALE DEVELOPMENT

This paper calls into question traditional methods of measuring the social desirability of items and their use in scale construction. First, we make explicit that the proper focus for desirability studies of items and traits are the rated desirabilities of the alternative item responses indicating different trait levels. Second, the results from our first study show that the relation between degree of endorsement of an item and its judged desirability level is often nonlinear and varies across items such that no general model of item desirability can be adopted that will accurately represent the relations across all items, traits, and trait levels. In addition, the nature of these relationships can vary depending on whether desirability is considered in a work or general context. Third, results from a second study indicate specifically that people when instructed to self-present in a maximally desirable manner will choose for some attributes a moderate level of endorsement (e.g., "agree") rather than a more extreme response option (e.g., "strongly agree"). Subjects offer several different reasons for viewing the less extreme response options, which yield more moderate trait level scores, as more desirable. These reasons are linked to perceptions of the more extreme response option as being associated with negative behaviors and concerns about how others will view a more extreme response to the item. Both studies indicate that desirable responding to personality items is more complex than previously believed.     

A sexual and a marital defensiveness scale for each sex

Abstract

A scale to measure defensiveness about the marital relationship and another to measure defensiveness about the sexual relationship of couples were developed for each sex. Defensiveness was defined as the tendency to endorse socially desirable items which are unlikely to occur and deny socially undesirable items which characterize most honest responders. The social desirability scale value of the items was empirically determined, and a traditional cross-validation design with two independent groups was used in the item analyses. Cronbach's alpha reliability coefficient ranged between. 75 and 93 for the male and female versions of the scales. The scales correlated higher with another defensiveness scale than with a social desirability scale. Clinicians' ratings of the items in the scales suggested that the scales were not diagnostic of sexual or marital psychopa-thology. Evidence is presented to support that these content specific scales surpass a global defensiveness scale as a measure of defensiveness regarding the sexual or marital relationship of couples.     

Methods of coping with social desirability bias: A review

Social desirability is one of the most common sources of bias affecting the validity of experimental and survey research findings. From a self-presentational perspective, social desirability can be regarded as the resultant of two separate factors: self-deception and other-deception. Two main modes of coping with social desirability bias are distinguished. The first mode comprises two methods aimed at the detection and measurement of social desirability bias: the use of social desirability scales, and the rating of item desirability. A second category comprises seven methods to prevent or reduce social desirability bias, including the use of forced-choice items, the randomized response technique, the bogus pipeline, self-administration of the questionnaire, the selection of interviewers, and the use of proxy subjects. Not one method was found to excel completely and under all conditions in coping with both other-deceptive and self-deceptive social desirability bias. A combination of prevention and detection methods offers the best choice available.     

Type A Personality,Self-Control,and Vulnerability to Stress

The Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A; Butcher et al., 1992) was released in 1992 and has rapidly become the most widely used objective personality assessment instrument with adolescents. Although the MMPI-A reduced or eliminated several problems associated with the use of the original MMPI (Hathaway &; McKinley, 1943) with adolescents, the MMPI-A does produce a high frequency of within normal limits basic scale profiles for individuals with substantial psychopathology including adolescents in inpatient psychiatric settings. To better understand the reasons for this phenomenon, we compared the item endorsement frequencies for the MMPI-A normative sample with results from two adolescent clinical samples, and these results were contrasted to the item endorsement frequencies for the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, &; Kaemmer, 1989) normative sample and a clinical sample of adult psychiatric inpatients. Results showed that the MMPI-A contains a substantial number of items that do not show a significant difference in item endorsement frequency between normative and clinical samples. Furthermore, MMPI-A basic and content scales generally show a much lower percentage of effective items than do the corresponding scales for the MMPI-2. We discuss the findings in relation to the frequent occurrence of low range MMPI-A profiles in clinical samples and the potential usefulness of these results in future efforts to develop viable short forms for the MMPI-A.     

The effectiveness of MMPI-A items in discriminating between normative and clinical samples.

Assessing the person reliability of an individual MMPI protocol

This study investigated various measures commonly employed to assess the person reliability of an individual Minnesota Multiphasic Personality Inventory (MMPB protocol. Specifically, relationships among indices of person reliability and the standard MMPI validity scales were examined using the responses of 82 subjects who completed the MMPI on two occasions separated by 1 week. Person reliability indices were based on within-occasion responses to identical and to psychologically similar items, and on three across-occasion response consistency measures. The validity scales, namely, the L, F, K, and Cannot Say scales, showed higher test-retest stability than the within-occasion person reliability indices. Further, the validity scales and person reliability indices appeared to reflect multiple facets of dependable responding. Interestingly, an individual's tendency to change responses to MMPI items from the test to the retest was significantly predictable. Clinical implications of these findings were derived.     

A Latent Trait Analysis of the MMPI

Commonly used techniques for analyzing the structure of the MMPI scales were discussed and the use of a latent trait model was suggested as an alternative. The items on each scale of the MMPI were calibrated using a discrimination statistic. The item calibration statistics obtained from a replication sample were highly correlated with those obtained in the first sample. Poor fitting items were identified, and possible reasons for poor fits were discussed. The scales generally had few poor fits. The poor fitting items were generally those identified by Wiener (1956) as comprising the "subtle" subscales of the test.     

Personality Factors S,E, and M,and their Measurement

Terms such as often, usually, and sometimes frequently modify items found in personality questionnaires. Semantic style refers to individual differences in the quantitative meanings subjects give such terms. This study investigated the relation between semantic style variables and questionnaire measures of social desirability, extraversion, and neuroticism. Significant associations were found for two of these three personality scales: social desirability and neuroticism. If semantic style is shown to be pervasive and appreciable in its influence on questionnaire response, its systematic control should become a psychometric goal of some importance. Techniques are discussed for thus achieving more valid questionnaire measures.     

Testing the Effectiveness of Family Therapeutic Assessment: A Case Study Using a Time-Series Design

This study reports normative data for the Peebles Rorschach content scoring system. Group Rorschach protocols from undergraduates were scored and reliably classified by quadrant. Frequencies were obtained by sex and by quadrant. Social desirability was demonstrated to vary across quadrants. The validity of quadrant classification was suggested by self-reports and MMPI scales. MMPI profile code predictions were made by experts for each quadrant and compared with obtained mean profile codes. The scoring system was evaluated and theoretical origins were discussed.     

Social desirability of subtle and blatant prejudice scales

The present paper analyzes the relation between the measurement of subtle and blatant prejudice proposed by Pettigrew and Meertens in 1995 and the tendency to give socially desirable responses. It also tests whether items that measure subtle prejudice are judged as more socially desirable than those that measure blatant prejudice. Data were obtained from two groups, one of 497 Italian high school students and one of 77 university students. In the first case, the analysis concerns the relation between the prejudice scores and scores on a shortened form of Marlowe and Crowne's Social Desirability Scale. In the second case, we analyzed the social desirability judgments expressed on single items of the Petrigrew and Meertens scales. Analyses indicate that (1) neither Subtle nor Blatant Prejudice scores correlate with the tendency to give socially desirable responses and (2) when the items of the two prejudice scales are placed in order on the social desirability continuum, with very few exceptions the Blatant Prejudice items are situated at the not socially acceptable pole and Subtle Prejudice items at the socially acceptable pole.     

Development of the Revised Sex-Role Behavior Scale

This study describes the construction of the Revised Sex-Role Behavior Scale (SRBS-2), a 240-item self-report inventory comprised of male-valued, female-valued, and sex-specific items in four interest/behavior areas: Recreational and leisure activities, vocational preferences, social interaction, and marital behaviors. Two-hundred sixteen items were administered to 520 undergraduate males and females under three instructional sets. One-third of the subjects compared the typical young adult man and woman on the items, one-third rated the desirability of the items for men and women, and the remaining subjects rated themselves. Subjects in this latter condition also rated the 160 items from the SRBS-1. Typical and desirability ratings were used to select items to add to the SRBS-1 male-valued (more typical of men but desirable for both sexes), female-valued, and sex-specific (more typical of one sex and desirable only for that sex) scales. The resulting overall and area subscales had adequate internal consistency. Intercorrelations among the area subscales showed a fair degree of consistency across behavior areas, suggesting that global sex-role behavior assessments may be obtained with the overall SRBS-2 scales but that more detailed and accurate assessments require the use of separate area subscale scores.     

Assessing MMPI constructs through the measurement of response latencies

Responses to the Minnesota Multiphasic Personality Inventory (MMPI) were assessed with respect to their relevance to schema theory. The relation between scores on self-reported personality dimensions and the speed of processing test items associated with each dimension was examined. With previously derived factor analytic content scales, negative correlations were obtained between scale scores and mean latencies for endorsing relevant items, and positive correlations were found between scale scores and mean latencies for rejecting relevant items. A similar analysis completed on the traditional clinical scales revealed no such pattern. Results were interpreted as supporting the conceptualization of item responding as a content-based, schema-relevant process.
