DAPP-BQ: factor structure and relations to personality disorder symptoms in a non-clinical sample

We assessed the factor structure of the DAPP-BQ (Livesley & Jackson, in press), as well as the relations between DAPP-BQ higher- and lower-order personality trait scores and DSM-IV (APA, 2000) personality disorder symptoms in a sample of approximately 300 nonclinical young adults. The four-factor structure of the DAPP-BQ was replicated, and DAPP-BQ higher-order and lower-order scores were related to personality disorder symptoms in predictable ways. Finally, regression analyses revealed that specific DAPP-BQ traits accounted for variance in individual personality disorder scores above and beyond comorbid personality disorder symptoms.     

DAPP-BQ: factor structure in French Canadians

Personality traits may be involved in predisposition to a range of clinical and behavioral phenotypes. Given their importance, it is necessary to establish the extent to which different levels of personality traits are applicable to and reproducible across cultures and sexes. In a well-characterized, longitudinal sample of young French Canadians, we examined structural equivalence of broad personality traits using the Diagnostic Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ). We also investigated sex-based patterns of item-endorsement, scale reliabilities, and factor solutions. Our four-factor solution closely resembles the structure reported in the source population of British Columbians, especially in terms of Factors I through III. In contrast to the original study, however, together with compulsivity, rejection rather than passive aggression, defined Factor IV. We, furthermore, observed sex-based differences in item endorsement and both broad and narrow personality trait scores. Subtle differences notwithstanding, our results offer additional evidence for structural stability of broad DAPP-BQ personality traits across sociodemographic and cultural contexts.     

The Dutch DAPP-BQ: improvements, lower- and higher-order dimensions, and relationship with the 5DPT

After modifying 53 items in a previous Dutch translation of the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ; Livesley & Jackson, 2002), the present DAPP-BQ scales (with or without Self-Harm included) were subjected to a principal components analysis with oblimin or varimax rotation in a general population sample of 478 subjects, retaining four factors. All four (higherorder) factors (Emotional Dysregulation, Dissocial, Inhibition, and Compulsivity) proved identical to the factors originally derived in Canada, with Tucker coefficients of factor similarity approaching unity. Particularly the (unexpected) finding that the present Dutch version of the DAPP-BQ also resulted in an Inhibition factor (and not, like the former Dutch version, in an Intimacy Problems factor) was considered positive. In addition, a principal components analysis with oblimin rotation was conducted on the 282 items contained in the 18 DAPP-BQ scales, investigating the lower-order structure of the DAPP-BQ; in this case, 18 factors were retained. Although the structure originally derived by Livesley and colleagues could not be recovered completely, the degree of similarity was of such a magnitude that the 18 DAPP-BQ scales were considered to give a dependable account of the "true" lower-order structure of disordered personality. Moreover, based on the finding that the 18 scales are sufficiently reliable (Cronbach's alpha) and correlate as predicted in a subsample of 284 subjects with the normal personality scales of Van Kampen's 5DPT (or, Five-Dimensional Personality Test), the DAPP-BQ appears to be a valuable instrument.     

Fatigue: relationships with basic personality and temperament dimensions

This study examined the relationships between the Five-Factor-Model (FFM) personality dimensions (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness/Autonomy), the Pavlovian temperament variables (Strength of Excitation, Strength of Inhibition, Mobility), and fatigue. We expected that all these person characteristics would be negatively associated with fatigue. In a survey among persons working at least 20 h a week (N=765), respondents completed a personality questionnaire (the Five-Factor Personality Inventory), a temperament scale (the Pavlov Temperament Survey), and two fatigue questionnaires (the Checklist Individual Strength-20 and the Emotional Exhaustion scale of the Maslach Burnout Inventory). Results indicated that high scores on Autonomy, and low scores on Extraversion, Conscientiousness, Emotional Stability, and Strength of Excitation were, in various combinations, predictors of higher fatigue scores. Agreeableness, Strength of Inhibition, and Mobility did not play a role in the prediction of any fatigue score. In conclusion, personality and temperament dimensions explained significant proportions of the variance in fatigue. It is stated that there is an urgent need for longitudinal studies in order to examine the predictive value of the personality dimensions over time.     

The basic components of adult playfulness and their relation with personality: The hierarchical factor structure of seventeen instruments

The primary aim of this study was testing the structure of adult playfulness in a joint analysis of seventeen questionnaires and testing the relation of the factors with the big five personality traits. A sample of 244 adults completed the questionnaires and a five factor-solution fit the data best; i.e., (a) Humorousness; (b) Cheerfulness–Uninhibitedness; (c) Expressiveness; (d) Other-directedness; and (e) Intellectuality–Creativity. Correlation analyses (bivariate, canonical) and regression analyses indicated strong overlap of the broader personality factors and the Cheerfulness–Uninhibitedness-factor (extraversion and emotional stability) as well as the Expressiveness-factor (extraversion). The study contributes towards a better understanding of the structure of playfulness in questionnaires developed for adults. Implications for future research are discussed.     

The relationship between psychological type and the three major dimensions of personality

Five hundred and fifty-four undergraduate students attending a university-sector college in South Wales, United Kingdom, completed the Myers-Briggs Type Indicator (MBTI) (Form G) and the short-form Revised Eysenck Personality Questionnaire. The results showed a number of statistically significant relationships between the two models of personality and drew attention to two substantively significant relationships. In Eysenckian terms, the Myers-Briggs Type Indicator constructs of introversion and extraversion translated as “neurotic introversion” and as “stable extraversion.” The Myers-Briggs Type Indicator constructs of judging and perceiving translated as “low psychoticism” and “high psychoticism”. Based on their interpretation of findings, the authors argue that the MBTI and the Eysenckian models should be viewed as interacting in a dynamic and informative fashion, not as unrelated, totally disparate models.     

The relationship between five-factor personality measurements and ICD-10 personality disorder dimensions: results from a sample of 229 subjects

This article examines the relationship between the five-factor model (FFM) and dimensional ICD-10 personality disorders. In a follow-up study of a child and adolescent psychiatric cohort, former patients and controls were assessed with NEO-FFI and the IPDE interview (CD-10 personality disorder). Full data were available for 229 subjects (149 former patients, 80 controls). Multiple regression analysis showed that the five factors of the FFM as independent variables explained between 5% (schizoid personality disorder) and 32% (anxious personality disorder) of the variance of ICD-10 dimensional personality disorder scores. For the two types of emotionally unstable personality disorder dimension (impulsive and borderline), for anxious (avoidant) personality disorder dimension and for the total score of any personality disorder dimension, FFM explained between 17% and 32% of the variance with almost identical results for the former patient group and the control group. High neuroticism was a feature of paranoid, emotionally unstable, histrionic, anankastic, anxious (avoidant), and dependent personality disorder dimensions, whereas low agreeableness was found in dissocial, emotionally unstable and histrionic personality disorder dimensions. Low extraversion was found in schizoid, anxious (avoidant) and dependent personality disorder dimensions, whereas histrionic PD dimension correlated with high extraversion. We find that the FFM is valuable for the further understanding not only of DSM-IV but also of ICD-10 personality disorder dimensions. The differences between ICD-10 and DSM-IV in this respect seem to be small.     

Structure of personality pathology in normal and clinical samples: Spanish validation of the DAPP-BQ

Given that the DSM taxonomy of personality disorders is flawed by severe classificatory problems, the development of alternative classificatory systems, such as the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ), has now become a priority. This study examined the internal consistency, second-order factor structure, and criterion validity of a Spanish translation of the DAPP-BQ in two samples: subjects with personality disorder (n = 155) and subjects from the general population (n = 300). Alpha coefficients ranged satisfactorily from .75 to .93. Four second-order factors of Emotional Dysregulation, Dissocial Behavior, Inhibitedness, and Compulsivity were obtained, which were replicable between samples and identical to those reported in the literature. Finally, disordered subjects scored significantly higher than normal subjects on 17 of the 18 DAPP-BQ traits. Some pending issues in the construction of an alternative taxonomy of personality disorders are discussed.     

Factor structure of the basic personality inventory with incarcerated offenders

The item and scale factor structure of the Basic Personality Inventory (BPI) was examined in a sample of 486 offenders incarcerated for violent and sexual crimes. Separate principal-component analyses of the items for each of the 11 clinical scales, critical item scale, and social desirability scale indicated a one-dimensional factor solution for all scales except Depression and Persecutory Ideation. The Depression scale's two factors were Hopelessness and Depressive Affect and the Persecutory Ideation scale's two factors were General Paranoia and Perception of External Control. Although the factors for these two scales may assist in interpretation, the correlations between the factors and the total score of their respective scale were high. Confirmatory factor analysis of the 220 items from the 11 clinical scales supported the factorial logic of the scoring key. Analysis of the 11 clinical scales resulted in two factors: General Psychopathology/Adjustment and Antisocial Orientation. The results suggest that all but two scales can be viewed as unidimensional thereby allowing for a straightforward clinical interpretation. These analyses support the internal structure of the BPI and lend credence to external validity work with forensic populations.     

The relationship between Eysenck's major personality dimensions and simultaneous and sequential processing in children

The present study reexamined Eysenck's hypothesis that intelligence and personality are uncorrelated. Intelligence was measured with the Kaufman Assessment Battery for Children, yielding scores for simultaneous and sequential processing and achievement, and the Woodcock-Johnson Brief Scale. Personality was assessed with the Junior Eysenck Personality Questionnaire. Ss were 105 children, ages 8$\text{1}\text{2}$10$\text{1}\text{2}$yr. Although a process as well as a product-oriented intelligence test was employed, the correlational and discriminant analyses supported Eysenck's original hypothesis.     

The hierarchical structure of the Dimensional Assessment of Personality Pathology (DAPP-BQ)

Hierarchical personality models have the potential to identify common and specific components of DSM-IV personality disorders (PDs), and may offer a solution for the re-tooling of personality pathology in future versions of the DSM. In this paper, we examined the hierarchical structure of the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ; Livesley & Jackson, 2009) and the capacity of various trait components at different levels to predict DSM-IV PD symptoms. Participants were 275 psychiatric outpatients and 365 undergraduate students. Goldberg's (2006) bass-ackwards method was used to investigate the hierarchical structure of the DAPP-BQ. The predictive capacity of hierarchy components was assessed. We found that Level 5 of the hierarchy enhanced the capacity of the DAPP-BQ for predicting DSM PD symptoms beyond a four-factor structure, particularly for borderline PD.     

Factor structure of the MCMI basic personality scales and common-item artifact

The eight basic personality scales of the Millon Clinical Multiaxial Inventory (MCMI) were derived from Millon's theory of personality, but the adequacy of the MCMI for measuring Millon's personality constructs has never been assessed. One major problem with using factor analysis to illuminate the structure of the MCMI personality scales is that artifactual structure may result from item overlap among the scales. To analyze this, item-overlap coefficients were factored and compared to the factor structures of five subject samples. For the eight basic personality scales, three factors emerged for the overlap matrix and each of the five sample matrices: Aloof-Social, Aggressive-Submissive, and Lability-Restraint. It was concluded that these three factors are inconsistent with Millon's theory and that they will be found artifactually across a wide variety of populations due to overlapping items.     

Attachment dimensions and the big five personality traits: Associations and comparative ability to predict relationship quality

Several studies have explored associations between measures of adult attachment style and the Big Five personality traits or factors, but the studies have not included current dimensional measures of attachment style (Brennan, Clark, & Shaver, 1998) or the most complete (NEO-PI-R; Costa & McCrae, 1992) and frequently used (BFI; John, Donahue, & Kentle, 1991) measures of the Big Five. Moreover, most studies after Shaver and Brennan’s (1992) have not compared attachment style and Big Five measures as predictors of relationship quality. Here, we summarize past research and report two studies comparing Brennan et al.’s two-dimensional measure of attachment style with the BFI and NEO-PI-R measures of the Big Five. There are consistent and theoretically meaningful associations between the attachment-style and personality trait measures, but attachment-style dimensions still predict relationship quality better than measures of the Big Five. Implications are discussed.     

The big five personality dimensions and entrepreneurial status: a meta-analytical review

In this study, the authors used meta-analytical techniques to examine the relationship between personality and entrepreneurial status. Personality variables used in previous studies were categorized according to the five-factor model of personality. Results indicate significant differences between entrepreneurs and managers on 4 personality dimensions such that entrepreneurs scored higher on Conscientiousness and Openness to Experience and lower on Neuroticism and Agreeableness. No difference was found for Extraversion. Effect sizes for each personality dimension were small, although the multivariate relationship for the full set of personality variables was moderate (R = .37). Considerable heterogeneity existed for all of the personality variables except Agreeableness, suggesting that future research should explore possible moderators of the personality-entrepreneurial status relationship.     

Manic-depressiveness and Jungian dimensions of personality
