Four aspects of the item content of personality inventories were studied: the area of psychological functioning addressed (cognitive, preferences, feelings, behavioral), degree of reference to situational factors, degree of reference to response frequency, and the nature of reference to time. Three judges rated items of the California Psychological Inventory, Eysenck Personality Inventory, Maudsley Personality Inventory, Minnesota Multiphasic Personality Inventory, Jackson Personality Research Form, and Sixteen Personality Factor Questionnaire. Behavioral acts were found infrequently addressed in inventory items, and the other areas of functioning were approximately equally represented. More than half of the items referred to situation characteristics, 39% included the notion of frequency of behavior or experience, and most referred to the present. Rating reliabilities were also presented, and results for individual inventories were compared. Implications for controversies in the field of personality were discussed.
One hundred twenty-nine patients who were treated by lumbar laminectomy for discogenic disease were evaluated preoperation by means of the Millon Clinical Multiaxial Inventory (MCMI) and the Minnesota Multiphasic Personality Inventory (MMPI). At follow-up evaluation, there were 71% good, 18% fair, and 11% poor surgical results. Patients with fair or poor outcomes scored significantly higher in the hypochondriasis, depression, hysteria, and psychasthenia scales in preoperative MMPI testing. These patients also showed significant differences on the MCMI asocial, gregarious, and neurotic depression scales. The MMPI profiles had a higher correlation with successful treatment than did those of the MCMI. The MMPI can help identify patients whose pain syndrome has a significant psychosocial component, and it can easily be used by orthopedic surgeons to facilitate referral and treatment planning.
Empirical work on psychopathology and delinquency requires concise and specific instruments. The Weinberger Adjustment Inventory (WAI), was correlated with the Minnesota Multiphasic Personality Inventory (MMPI) using a sample of incarcerated adolescent males (N = 178). The distress dimension of the WAI was significantly and positively associated with scales 2, 4 and 7 of the MMPI. The restraint dimension was significantly and positively associated with the Lie and K scales of the MMPI. Distress and restraint were distinct dimensions. The WAI may be a brief and helpful personality measure, determining responses to conflict and subjective stress in delinquents with poor reading skills and other special education impairments. The length of the WAI makes it especially suitable for populations such as incarcerated adolescent males who exhibit short attention spans and frequent episodes of noncompliant and resistant behavior.

The Psychopathic Personality Inventory (PPI; S. O. Lilienfeld & B. P. Andrews, 1996) is a self-report test that has shown considerable promise as a screening measure for psychopathy. A current limitation of the PPI is that no data exist regarding the impact of response sets such as positive impression management. Although the PPI contains a validity scale (Unlikely Virtues) designed to identify response biases such as "faking good," its utility has not yet been assessed. In this study a repeated measures analogue design was employed in which 186 respondents completed the PPI both under standard conditions and with specific instructions to create a favorable impression of themselves. In the "fake good" condition, participants were able to appear significantly less psychopathic, with those who obtained higher scores in the standard instruction condition showing the largest decreases in their PPI scores. Receiver Operating Characteristic analyses indicated that, although the Unlikely Virtues scale significantly differentiated between "fake good" and honest protocols (area under the curve = .73), a considerable number of misclassifications occurred. The clinical and forensic implications of these findings are discussed.

Hypothesized that rating bogus "personality feedback" and answering personality inventory items are both instances of the same general behavior. After undergraduates were administered personality inventories, they were asked to evaluate the accuracies of personality descriptors under differing instructional sets. In support of the hypothesis, a Barnum Group's (N equal to 24) personality inventory responses and "personality feedback" ratings correlated significantly and as highly as Reliability Controls' (N equal to 24) alternate forms reliability coefficient. Inventory responses and "feedback" ratings were affected equally by the descriptors' favorability and by the Ss' defensiveness. Contrary to the hypothesis, descriptors were rated as more personally accurate when presented as "feedback" than when presented as test items. Theoretical and applied implications of the findings are discussed.
Millon Adolescent Personality Inventory differential diagnosis of disruptive behavior disorder vs no behavior disorder was investigated. Results were twice cross-validated. Millon adolescent Scales 4, 5, 6, G, SS, and TT were closely related to diagnosis of behavior disorder. Two psychometric rules averaged 70% hits and 35% false positives over three samples, Rule 1 of > 2 elevations (baserate score > 63) among Scales 6-G-SS-TT and Rule 2 of Scale 4 elevated with Scale 5 or with one of 6-G-SS-TT. An ancillary rule was highly specific to behavior disorder (90%). Two broad dimensions or factors appeared to be represented in the key scales; Scales 4 and 5 exemplified a histrionic-narcissistic factor, while the 6-G-SS-TT combination typified behavioral conflict and instability.
Eysenck's personality inventory (EPI) was administered to 653 females and 666 males. Item analyses were carried out for the subsamples and the combined sample. In addition hierarchical oblique factor analysis was applied to the data. The purpose of both item and factor analysis was to examine the psychometric properties of the EPI in regard to (a) the homogeneity of the scales, in terms both of internal and external item-scale relationships (b) the univocality of the scales assessed in factor analytic terms. It was found that the neuroticism scale was superior to the extraversion scale in both these respects.
By using the Adjective Check List (ACL) in its Japanese version, the concurrent validity of a personality inventory is investigated through canonical correlation analysis and procrustes factor rotation from the view of the Five Factor Model concerning personality traits. After describing the objective of the present paper, the principles both of canonical correlation analysis and of incomplete orthogonal procrustes factor rotation to be used are explained. And, following the description concerning samples and data for analysis, the results both based on the scales and on the items of the personality inventory are presented. The important role of procrustes type of factor rotation in editing personality inventory is stressed before closing the discussion.
The personality correlates of study difficulty and academic performance in university students have been measured in terms of psychiatric symptomatology and premorbid characteristics. The UCLSQ, MHQ and DPI were administered to two groups of male and female students presenting at an health centre: one (n = 72) of patients seeking psychological help, the other (n = 73) a control group. Significant differences between the two groups were formed on the MHQ, confirming previous results; and these were supplemented by differences on the DPI. Motivational and psychoneurotic components of study difficulty were significantly related to MHQ scores in both groups. DPI scores were more closely related to study difficulty in the patients than controls; and served particularly to characterize their sylbism and work satisfaction. The DPI added to the picture of a subgroup of students observed both in an earlier and the present study: academically successful patients scoring high on phobic anxiety.
The Jackson Personality Inventory--Revised comprises 15 bipolar scales and five cluster scores concerning an individual's interpersonal patterns of interaction, cognitive styles, and value orientation. Recent reviews of this revised version raise questions about test-retest stability as well as the factor structure on which cluster scores are based. 74 men and 33 women (29-63 years of age, M = 42.3) completed the inventory while participating in a continuing education program. Of these 45 participated in a second session 13 wk. later. Test-retest correlations are significant, with 12 of the 15 scales having correlations > or = .75. Intercorrelations among all subscales indicate that the Jackson subscales for the most part remain distinct from each other ranging from .01 to .59. A Principal Components Analysis with a varimax rotation yielded three factors that parallel the NEO big five, i.e., Openness, Neuroticism, and Extroversion and replicated previous factor structure found for both versions of the Jackson inventory. The fourth and fifth factors here were labeled Trustworthy and Organization; however, the composition of these factors across several studies appears to be unstable, suggesting optimal certainty when interpreting the clusters of subscales associated only with Openness, Neuroticism, and Extroversion. Further research may help clarify the instability associated with the other factors of this inventory.
Studies of the personality of the pathological gambler have consisted primarily of case reports and findings on the MMPI. This article presents data on a sample of 70 pathological gamblers, 70 alcoholics in treatment, and 70 medical/surgical controls on the California Personality Inventory (CPI). Gamblers and alcoholics differed significantly from hospitalized controls on a number of scales, particularly on measures of socialization, ego control, and flexibility. Differences between the gamblers and alcoholics were few, with a trend for the alcoholics to be similar to the gamblers and intermediate between the other two groups. Implications for the treatment of the pathological gambler are discussed.
Correlations of scores on the Eysenck Personality Inventory with those of the SONSO Personality Inventory, a test of five factors of personality, were estimated for 300 junior college students. Extraversion and Neuroticism show reasonably close correspondence to the Shyness and Nervousness scales of the SONSO.

A personality inventory was developed as an aid in securing history and beliefs relevant to the assessment of personality structure and the diagnosis of personality disorders. The inventory was developed by restating DSM diagnostic criteria in everyday language, rewording the resulting statements in the form of True/False questions, and placing these questions in a short, self-paced booklet which subjects could complete in about 15 minutes. The following assessments were made and discussed: construct validity, split-half reliability, test-retest reliability, comparison with a standardized interview, and comparison with actual clinical assessments. The personality inventory is discussed as a useful accompaniment to the diagnostic interview in clinical settings and for research into personality structure and personality disorders.
Objective personality assessment instruments offer a comparatively underutilized source of clinical data in attempts to evaluate and predict risk for suicide. In contrast to focal suicide risk measures, global personality inventories may be useful in identification of long-standing styles that predispose persons to eventual suicidal behavior. This article reviews the empirical literature regarding the efficacy of established personality inventories in predicting suicidality. The authors offer several recommendations for future research with these measures and conclude that such objective personality instruments offer only marginal utility as sources of clinical information in comprehensive suicide risk evaluations. Personality inventories may offer greatest utility in long-term assessment of suicide risk.
