Individual differences in cognitive strategy and personality traits as measured by the Sixteen Personality Factor Questionnaire

The relationship between personality and preference for use of the right or left hemisphere of the brain in cognitive processing was investigated. Lateral eye movements were recorded as 50 female and 20 male right-handed subjects considered questions requiring reflection. The questions were not obviously "verbal" or "spatial" in nature but did require differing levels of reflection. Questions requiring higher levels of reflection produced a higher rate of lateral eye movement responses. Percent right eye movement for individual subjects was then correlated with scores on the Sixteen Personality Factor Questionnaire, using both first-order factors and the second-order factor Cortertia, which has some face validity as describing the personality generally ascribed to those who produce mostly right lateral eye movements. No correlation was found between the preferred directions of eye movements and 16 PF factors, which suggests that the lateral eye movements reflect thinking and problem-solving strategies but are not associated with personality styles.     

The Sixteen Personality Factor Questionnaire and Its Junior Versions

In this article the author describes the Sixteen Personality Factor Questionnaire (16PF) and its junior versions, the High School Personality Questionnaire (HSPQ) and the Children's Personality Questionnaire (CPQ). Development of the tests is described briefly. Reliabilities and validities of the tests are covered, with attention to applications in educational, clinical, and occupational settings.     

Further Evidence Concerning Motivational Distortion on the Sixteen Personality Factor Primaries by Male Felons

A multiple regression analysis was used to determine the susceptibility of the 16 Personality Factor Test (16PF) to faking for a sample of male felons. The study is a replication of an earlier study of a similar sample. Motivational distortion (MID) correlated significantly with the 16 PF primary scores. The relationship was most evident when the structure coefficients rather than the beta weights were analyzed. The findings were consistent with the previous results which indicated a fairly high degree of support for the MD corrections provided in the manual. An important exception was that Dominance (E) was suppressed by individuals from both samples when MD was present.

Personality types as measured by the 16 PF

The possibility of isolating personality types using 16 PF profiles was studied by utilizing a Q-type factor analytic procedure. Four modal profiles, characteristic of major clusters of subjects, were derived and cross validated. These four major types successfully classified approximately 2/3 of the 16 PF protocols (n = 1037), and classified similar proportions of previously published profiles. Variation of classification rates as a function of race and sex was described, and strategies for utilizing the profiles for research and interpretive purposes were outlined.     

Factor structure of the Preschool Personality Questionnaire in Iran

This study is of Triandis's pseudoetic variety, not a cross-cultural study per se. The Preschool Personality Questionnaire which was standardized in the SA and partially standardized in Colombia was administered to 600 preschool children in Iran. Data from the entire sample were analyzed by both principal components, maximum likelihood, and alpha factor analyses. 14 factors were derived. Odd and even records were likewise factored. Six of the first seven factors were found and matched from odd to even cases. At least five of the total sample factors were judged by inspection to match similar dimensions in the USA. Factor scores for children in the standardizing sample were created by postmultiplying the raw score matrix by the 14-factor "reduced" factor structure matrix. These raw factor scores were then converted to STEN scores. Utilizing the entire sample factor structure matrix, factor scores and sten scores were derived for each of the 4-, 5-, and 6-yr.-old groups. By use of the norms based on this sample of Iranian children, further experiments can be carried out to investigate development of preschool children and other variables in Iran similar to those studied in the West.     

Factor analysis of the McCarthy scales for groups of white and Mexican-American children

Factor analyses of the McCarthy Scales of Children's Abilities (McCarthy Scales) were performed on separate groups of Anglo (N = 186) and Mexican-American (N = 126) children to determine the comparability of underlying structures and to examine the construct validity of the McCarthy Scales for each ethnic group. The subjects, ranging in age from 5.6 to 7.6 years, were randomly selected from school enrollment rosters and stratified by age, sex, and ethnicity. A principal component analysis produced three factors for the Anglo as well as the Mexican-American groups. Examination of the coefficients of congruence indicated a close similarity among the matching factors. Additionally, the factors which emerged for the Anglos and Mexican-Americans corresponded to the scales constituting the McCarthy Scales. The results of the study provide evidence for the construct validity of the McCarthy Scales for children of two ethnic groups.     

Personality characteristics of eating-disordered outpatients as measured by the Hand Test

The Hand Test was administered to 34 eating-disordered and 26 noneating-disordered college-age women to determine discriminating projective personality features. Eating-disordered women scored higher on response time, overall pathology, and passivity. Anorexics present more tension, aggression, and acting out potential whereas bulimics demonstrate significantly more passive responses. The more severely affected women scored higher on crippled, passive, and withdrawal variables. Similarities as well as differences between the groups may have important implications for the diagnosis of subgroups of eating-disordered women and for treatment planning.     

Patient Personality and Relational Patterns in Psychotherapy: Factor Structure,Reliability, and Validity of the Psychotherapy Relationship Questionnaire

The aim of this study was to examine the factor structure and the psychometric properties of the Psychotherapy Relationship Questionnaire (PRQ; Bradley, Heim, &; Westen, 2005 Bradley, R., Heim, A. K., &; Westen, D. (2005). Transference patterns in the psychotherapy of personality disorders: Empirical investigation. The British Journal of Psychiatry, 186, 342–349. doi:10.1192/bjp.186.4.342[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), a clinician report instrument that measures a wide spectrum of thoughts, feelings, motives, conflicts, and behaviors expressed by patients toward their therapists in psychotherapy. A national sample of psychiatrists and clinical psychologists (N = 314) of different theoretical orientations completed the PRQ, as well as the Shedler–Westen Assessment Procedure–200 (SWAP–200; Westen &; Shedler, 1999a Westen, D., &; Shedler, J. (1999a). Revising and assessing Axis II, Part I: Developing a clinically and empirically valid assessment method. The American Journal of Psychiatry, 156, 258–272.[PubMed], [Web of Science ®] , [Google Scholar], 1999b Westen, D., &; Shedler, J. (1999a). Revising and assessing Axis II, Part I: Developing a clinically and empirically valid assessment method. The American Journal of Psychiatry, 156, 258–272.[PubMed], [Web of Science ®] , [Google Scholar]) to assess the personality of a patient in their care. Factor-analytic procedures identified 6 transference dimensions that showed excellent internal consistencies: (a) hostile, (b) positive/working alliance, (c) special/entitled, (d) anxious/preoccupied, (e) avoidant/dismissing attachment, and (f) sexualized. Factor scores were significantly related to patients’ personality characteristics and psychological functioning, regardless of the clinicians’ orientations. The findings support that the PRQ is a valid and reliable tool for evaluating the patients’ relational patterns emerging in clinical practice in a clinically coherent and psychometrically robust way. Clinicians’ careful understanding of these patterns can be very useful for making accurate diagnostic formulations, as well as for providing a roadmap for effective therapeutic intervention.     

The relationship of alcohol, tobacco, marijuana, and other illegal drug use to delinquency among Mexican-American, black, and white adolescent males

This study examined the relationship between drug use and delinquent behavior among 348 high school males (154 whites, 172 Mexican-Americans, and 22 blacks) and 89 adjudicated delinquent males confined to a maximum-security facility for violent and repeat offenders (37 whites, 25 Mexican-Americans, and 27 blacks). Data were collected in the spring of 1986 using self-administered questionnaires. Analyses were performed separately for each racial subgroup. Simple correlations revealed that self-reported alcohol, tobacco, marijuana, and other illegal drug use were all significantly related to both minor and violent delinquency for all three racial groups. Multiple regression analysis revealed that the use of these substances accounted for 40% to 47% of the variance in minor delinquency and for 59% of the variance in violent delinquency among blacks, 53% of the variance in violent delinquency among Mexican-Americans, and 34% of the variance in violent delinquency among whites. The best predictors of violent delinquency were the frequent use of illegal drugs other than marijuana and use of tobacco, in that order, among Mexican-Americans; the frequent use of other illegal drugs, marijuana, and tobacco, in that order, for whites; and the frequent use of illegal drugs, followed by marijuana, for blacks.     

Revaluating the evidence for the General Factor of Personality in the Multidimensional Personality Questionnaire: Concerns about Rushton and Irwing (2009)

We evaluated whether the Big Five-based hierarchical model for the Multidimensional Personality Questionnaire (MPQ) reported by Rushton and Irwing (2009) would replicate in a second sample of 733 participants. We were unable to confirm their hierarchical model and detected problems with the reporting of the original results. Exploratory factor analytic investigations generally supported the canonical three factor solution for the MPQ described in the existing literature. This was the case for both the present dataset and for the correlation matrix analyzed by Rushton and Irwing.
