Positive impression management and its influence on the Revised NEO Personality Inventory: a comparison of analog and differential prevalence group designs.

Participants (n = 22) completed the Revised NEO Personality Inventory (NEO PI-R) as part of an authentic job application. Protocols produced by this group were compared with "analog" participants (n = 23) who completed the NEO PI-R under standard instructions and again under instructions designed to mimic the test-taking scenario of the job applicants (the "fake-good" condition). Participants completing the NEO PI-R under fake-good instructions and the job applicants scored lower on the Neuroticism and higher on the Extraversion scales than did the participants responding under standard instructions. Analog participants in the fake-good condition scored higher on the Extraversion and lower on the Agreeableness scales than did the job applicants. These results suggest that outcomes from analog designs are generalizable to real-world samples where response dissimulation is probable.

Psychometric analysis of the Psychopathic Personality Inventory (PPI) with female inmates.

This study evaluated the reliability, internal structure, and validity of the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) among female inmates (n = 153) housed at a multilevel prison facility. Findings from this research suggested both strengths and weaknesses associated with PPI psychopathy assessment. Reliability of the PPI was supported by internal consistency analyses of scale and subscale item sets, and test-retest reliability was supported by findings obtained with a subsample (n = 36) retested an average of 49 days after initial test administration. Validity of the PPI total score was also supported by moderate to very high correlations with other self-report measures of psychopathy. Relative weaknesses of the PPI were evident by the low or negative associations among many of the PPI subscales, moderate associations that PPI total scores demonstrated with response set indexes, and the similarity of PPI total scores among female inmates and undergraduates. Findings from this research are considered in relation to possible sex differences in the expression of psychopathy and challenges associated with the assessment of the psychopathy construct with self-report methods.

Factor structure of the Million Adolescent Personality Inventory for psychiatric inpatients.

A principal components factor analysis (with varimax rotation) was performed on the Millon Adolescent Personality Scale Base Rate scores of 335 adolescent psychiatric inpatients. A four-factor solution was obtained (accounting for 84.1% of the variance), which was similar to that obtained by Millon, et al, for the normative sample. Confirmatory factor analyses, however, using data obtained from computer generated random responses to the test, also fit the inpatient and normative sample data very well. The factor structure of the Millon Adolescent Personality Inventory therefore was inferred to be driven by the considerable item-scale overlap that characterizes the test.

Evaluation of an Icelandic translation of the Basic Personality Inventory using a bilingual sample.

This study investigated the similarity of Icelandic and English versions of the Basic Personality Inventory (BPI), a 240-item measure of psychopathology. Eighty-nine native Icelandic graduate students studying in North America completed both language versions of the BPI in a counterbalanced order with a retest interval of approximately one month. The results of this bilingual retest study confirmed the adequacy of the Icelandic translation. Specifically, scale means, test-retest coefficients, and reliability coefficients demonstrated that the BPI performed highly similarly in both language versions. These findings provide additional support for the adequacy and applicability of the Icelandic translation of the BPI.

A principal-components analysis of the Narcissistic Personality Inventory and further evidence of its construct validity.

We examined the internal and external validity of the Narcissistic Personality Inventory (NPI). Study 1 explored the internal structure of the NPI responses of 1,018 subjects. Using principal-components analysis, we analyzed the tetrachoric correlations among the NPI item responses and found evidence for a general construct of narcissism as well as seven first-order components, identified as Authority, Exhibitionism, Superiority, Vanity, Exploitativeness, Entitlement, and Self-Sufficiency. Study 2 explored the NPI's construct validity with respect to a variety of indexes derived from observational and self-report data in a sample of 57 subjects. Study 3 investigated the NPI's construct validity with respect to 128 subject's self and ideal self-descriptions, and their congruency, on the Leary Interpersonal Check List. The results from Studies 2 and 3 tend to support the construct validity of the full-scale NPI and its component scales.

The Minnesota Multiphasic Personality Inventory-2 across the human immunodeficiency virus spectrum.

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) was used to assess individuals' patterns of psychological symptoms across the spectrum of HIV illness. Two hundred and twenty-five participants in the present sample were administered the MMPI-2, 61 were HIV-seronegative controls, 61 were asymptomatic, 36 were symptomatic, and 67 met criteria for AIDS. Symptomatic HIV-seropositive patients scored higher on the Hypochondriasis, Conversion-Hysteria, and Depression Scales. These differences appeared to be largely due to an increase in somatic complaints rather than an increase in other depressive symptoms. Group differences did not appear to be due to HIV-associated neuropsychological dysfunction. Interpretive strategies for the MMPI-2 and treatment considerations are discussed.

Narcissism and empathy: validity evidence for the Narcissistic Personality Inventory.

Three empathy questionnaires were correlated with scores on the Narcissistic Personality Inventory (NPI), and the predicted negative relationship was observed in two of the three cases. In addition, the Exploitiveness/Entitlement (E/E) subscale of the NPI was inversely related to all three empathy scales and directly related to another hypothesized measure of narcissism. Unexpected negative correlations between the E/E subscale and social desirability scales were interpreted as evidence of E/E subscale sensitivity to the manipulative dimension of narcissistic relationship styles. These data further support the construct validity of the NPI in general and of the Exploitiveness/Entitlement subscale in particular.

[Possibilities of computer-assisted administration of the revised Freiburg Personality Inventory. 2 experimental studies].

Empirical results of two studies on the practice of computer administration of psychodiagnostic inventories are presented. Based on the "Freiburger Persönlichkeitsinventar" (FPI-R, a German multidimensional personality inventory, Fahrenberg, Hampel & Selg, 1994) two studies (total N = 600 university students) were conducted in which (1) the standard paper-pencil questionnaire was compared with a computer administrated version, and (2) the standard item arrangement was contrasted with the presentation of the items of each subscale as a block (homogeneous item blocking), which corresponds to the extraction of subscales from more extensive inventories. The results confirm low significant effects of computer administration and of item blocking as to the means, as well as no interactions with the factor "gender." The parameters of reliability increased partially under computer administration. Computer administration itself led to a higher degree of self-consciousness. The adequacy of the FPI-R, which was standardized by paper-pencil inquest, and a computer administrated version is thus demonstrated proven.

Identifying adolescent runaways: the predictive utility of the personality inventory for children.

This study investigated whether runaway behavior could be related to six problematic areas. Selected scales of the Personality Inventory for Children, representative of the six areas, were hypothesized to discriminate between an adolescent runaway group and a control group. Four scales correctly classified 95.1% of the runaway subjects and 100% of the control subjects with a total correct classification rate of 97.52%. It was further hypothesized that the runaway group was not significantly different from a known clinical group with moderate to severe psychopathology. Results indicated that the runaway group was not significantly different except on one scale, Delinquency (DLQ). On the DLQ scale the runaway group had a significantly higher mean score than the clinical group. Application and recommendations are presented.

A longitudinal study of the effects of seizure symptoms on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical interpretation.

This study investigated whether the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) items reflecting seizure symptoms spuriously inflate MMPI-2 scores in persons with epilepsy. In a repeated measures prospective design, patients with epilepsy completed the MMPI-2 prior to epilepsy surgery and again two years later when they were either seizure-free or not seizure-free. Compared to baseline scores, only seizure-free patients showed a decline in endorsement of seizure items, and only on one scale, Hypochondriasis (Hs). Clinical profiles were not meaningfully different when readministered when seizures were no longer present. Moreover, profiles generated by individuals with and without seizures were not significantly different. We conclude the MMPI-2 is a valid test in an epilepsy population, as seizure content did not alter its clinical interpretation. In using the MMPI-2 in patients with epilepsy, a modest correction on the Hs and Schizophrenia (Sc) scales is warranted in selected cases. In MMPI-2 research, assessing both statistical and clinical significance is recommended.

Cognitive impairment in preschoolers: identification using the Personality Inventory for Children-Revised.

This study evaluated the clinical validity of the Intellectual Screening, Development, and Achievement scales of the Personality Inventory for Children-Revised (PIC-R), as well as the newly derived PIC-R Factor IV scale, in identifying cognitive impairment in a clinic-referred sample of preschoolers. The clinical validity of these PIC-R subscales was also compared to that of the Minnesota Child Development Inventory (MCDI). The results showed that the PIC-R scales and Factor IV were reasonably successful in identifying cognitively impaired preschoolers, but much less successful in identifying cognitively normal preschoolers. Overall, the MCDI was the most successful in correctly identifying the preschoolers' cognitive status.

Minnesota Multiphasic Personality Inventory: comparison of patients accepting and rejecting myopia surgery.

The Minnesota Multiphasic Personality Inventory (MMPI) was administered to 36 consecutive patients presenting to one surgeon as candidates for myopia surgery. Twenty-one patients proceeded to surgery, and 15 did not. The patients in this series were mature, nonaggressive persons whose basic and clinical MMPI scale values were generally within normal limits. No significant differences were found between the group that underwent surgery and the group that did not. In the group that underwent surgery, no personality characteristics were found to be associated with either a good or a poor surgical result. To our knowledge, this is the first report of the use of the MMPI to objectively evaluate personality characteristics of candidates for myopia surgery.

[Testing the significance of psychic factors in the etiology of alopecia areata. II. Examination of personality by means of Eysenck's Personality Inventory (MPI) adapted by Choynowski].

We evaluated the role of psychic factors in the etiopathogenesis of alopecia areata on the basis of Eysenck's Personality Inventory adapted by Choynowski. 55 patients were tested (28 women and 27 men). The control group consisted of 50 volunteers. The analysis of the results showed that the neurotic type of personality was predominant in the group of patients (43.64%). Neurotic personality found in such a high percentage of the patients with alopecia areata may be an additional element in the group of psychic factors that possibly have some influence on the development of the disease.

Adolescent Multiphasic Personality Inventory and its utility in assessing suicidal and violent adolescents.

Adolescent Multiphasic Personality Inventory profiles of inpatient adolescents were examined to identify differences between suicidal (danger to self, n = 145) and violent (danger to others, n = 36) adolescents. Participants were 181 inpatients (12-17 years old, mean age, 14.7 years) admitted to an adolescent psychiatric unit of a southern California county hospital. Results indicate that the suicide group had significantly higher scores than the violent group on five scales (Hypochondriasis, Psychasthenia, Paranoia, Schizophrenia, and Social Introversion). This scales, singly or in combination, have been found to be indicative of psychotic process. This suggests the presence of psychotic process in suicidal, but not violent, adolescents.

[Validation of the French version of the revised Personal Style Inventory (revised Personal Style Inventory, PSI-II, Robins et al., 1994)].

The aim of the present study is to determine the validity and reliability of the French version of the PSI-II. The PSI-II is a self-rating scale divided into two subscales containing each 24 items and rating sociotropy and autonomy. 202 university students (170 females, 32 males) with a mean age of 21.54 years (sd = 4.16) were included. They filled out the PSI-II and the Interpersonal Dependency Inventory (IDI). The construct validity was explored using an exploratory principal components analysis followed by an orthogonal varimax rotation. The results had shown a three-factor solution with a "sociotropy" factor and two "autonomy" factors. The Cronbach alpha coefficients were respectively 0.83 and 0.72 for the sociotropy and autonomy subscales. The Pearson correlations between the PSI-II and IDI subscales showed significant correlation first between the sociotropy subscale and the two subscales of the IDI rating dependency, the values were respectively 0.67 (p < 0.001) and 0.44 (p < 0.001), and secondly between the autonomy subscales of the PSI-II and IDI, the value was 0.39 (p < 0.001). The sociotropy subscale items correlated significantly with the total score of the subscale with a mean of 0.46. 23 items of the autonomy subscale correlated with the total score with a mean of 0.36. The sociotropy and autonomy scores were respectively 93.98 (sd = 14.22) and 84.55 (sd = 11.69). The French version of the PSI-II had satisfactory metrological parameters and allows to study sociotropy and autonomy in French population.

Internal and temporal reliability estimates for informant ratings of personality using the NEO PI-R and IAS. NEO Personality Inventory. Interpersonal Adjective Scales.

This study examines the internal consistency and temporal stability of informant ratings from two widely used instruments for normal personality assessment, the revised NEO Personality Inventory (NEO PI-R) and the Interpersonal Adjective Scales (IAS). Well-known adult targets were selected by 109 undergraduate students and rated on two occasions separated by a 6-month interval. With few exceptions, estimates of internal consistency are adequate to good for both instruments. NEO PI-R domain scores yield coefficient alphas ranging from .89 to .96, with a median of .80 for the 30 facet scales. IAS octant scales show coefficient alphas ranging from .83 to .92. Retest Pearson correlations are above .70 for each of the NEO PI-R domain scores and both IAS axis coordinates, and intraclass correlations are above .60 for all scales from both instruments. Score changes were small but statistically significant for three of the five NEO PI-R domains at retest. The retest stability of IAS type classifications varies as a function of the extremity of the associated octant scores.
