The DAPP-BQ in The Netherlands: factor structure and relationship with basic personality dimensions

After discarding eight items in the Dutch translation of Livesley's DAPP-BQ that showed item-total correlations < 0.20 in a sample of 223 normal subjects. Cronbach's alpha coefficients were calculated for the remaining items in the 18 scales of this instrument. The 'Dutch' alpha coefficients proved to be satisfactory. Furthermore, the Dutch DAPP-BQ scales were factor analyzed, retaining four factors. Three of these factors proved to be identical (Emotional Dysregulation and Dissocial) or nearly identical (Compulsivity) to the Canadian factors. However, the original factor Inhibition was not the same as the remaining Dutch factor Intimacy Problems. In a sample of 115 students, the estimated scores for the Dutch Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ) factors were correlated with the scales of Van Kampen's Four-Dimensional Personality Test. As expected, Emotional Dysregulation was found to correlate with Neuroticism, Dissocial with Insensitivity, and Compulsivity with Orderliness. The Intimacy Problems factor proved to be negatively correlated with Extraversion. The results obtained are embedded in the context of the evidence favoring a dimensional model of personality disorder. Furthermore, Livesley's proposal that separate diagnostic criteria for the existence of a personality disorder must be formulated to supplement the assessment by means of the DAPP-BQ is critically discussed.     

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.     

A comparison of personality function among patients with seasonal depression, nonseasonal depression, and nonclinical participants

Although a large body of research has accumulated concerning the relationship between nonseasonal depression and personality, comparatively few studies have examined the relationship between seasonal affective disorder (SAD) and personality. This study compared dimensional aspects of personality in patients diagnosed with SAD (N = 60), nonseasonal depression (N = 273), and nonclinical controls (N = 297) using the Dimensional Assessment of Personality Pathology (DAPP-BQ; Livesley & Jackson, in press). Analysis by ANCOVA indicated that significant between-group differences occurred in several of the 18 DAPP-BQ dimensions, with patients with SAD exhibiting personality psychopathology that was intermediate between the nonclinical sample and patients with nonseasonal depression. The results demonstrated that the traits associated with seasonal and nonseasonal depression differ in degree, not kind.     

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.     

Factorial structure of the German version of the dimensional assessment of personality pathology-basic questionnaire in clinical and nonclinical samples.

The Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ) assesses 18 traits to provide a systematic representation of the overall domain of personality disorders. We tested the cross-cultural stability of the prediction that four higher-order factors (Emotional Dysregulation, Dissocial Behavior, Inhibitedness, and Compulsivity) underlie the 18 basic traits. A total of 81 patients who were primarily treated for an Axis II personality disorder and N = 166 healthy control patients completed the German version of the DAPP-BQ. Results clearly confirmed cross-cultural stability of the postulated four-factor structure in both samples, accounting for 74.7% (clinical sample), and 65.7% (nonclinical sample) of the total variance. All four higher-order factors showed specific correlational relationships with dimensional assessments of DSM-IV personality disorders.     

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.     

An 8-item test of acrobatics and balance

A 14-item test of Acrobatics and Balance was previously developed to assess gross motor skills of high school physical education students. This study examined the factor structure of an 8-item version of the test based on exploratory and confirmatory factor-analytic techniques. The 8-item short-form of the Acrobatics and Balance test was administered to 334 Italian boys, ages 14 to 16 yr. (M = 15.0, SD= .8), during physical education lessons. The sample was then randomly split into two groups of equal size. Data from Group 1 were subjected to principal components analysis followed by oblimin rotation. Two factors emerged without overlapping items, accounting for 65.6% of variance. Factors included items of Acrobatics and Balance, matching the scales of the whole version of the 14-item test. Confirmatory factor analysis on data from Group 2 confirmed the two factor structure of the 8-item test. The test had a Cronbach coefficient alpha of .84. The Balance and Acrobatics scales had Cronbach alphas of .84 and .78 for Group 1 and of .84 and .77 for Group 2. Findings provided preliminary support for the use of the 8-item test, especially when there is a need to shorten assessment time.     

Cross-cultural replication of the five-factor model and comparison of the NEO-PI-R and MMPI-2 PSY-5 scales in a Dutch psychiatric sample

The authors investigated cross-cultural replicability of the five-factor model (FFM) of personality as represented by the revised NEO Personality Inventory (NEO-PI-R; P. T. Costa & R. R. McCrae, 1992) in a sample of 423 Dutch psychiatric patients. Also, NEO-PI-R domain scales were compared with the Personality Psychopathology Five (PSY-5; A. R. Harkness & J. L. McNulty, 1994) scales of the Minnesota Multiphasic Personality Inventory-2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 2002). Principal-components analysis with procrustean rotation confirmed the hypothesized structural similarity of the present sample with the U.S. normative factor scores. All of the hypothesized relations between NEO-PI-R and PSY-5 scales were confirmed. The results provide evidence for cross-cultural replicability of the FFM and for validity of the NEO-PI-R and PSY-5 constructs in the psychological assessment of psychiatric patients.     

Comparison of several shortened versions of the EMBU: exploratory and confirmatory factor analyses

The aim of the present study was to analyze the psychometric properties of different versions of the EMBU (Egna Minnen av Barndoms Uppfostran – My memories of upbringing) in a non-clinical sample of adolescents. The factor structure of the questionnaire was studied by means of more adequate exploratory and confirmatory factor procedures in order to ascertain which version achieves a better fit to data. The 64-item version of the EMBU was administered to a non-clinical sample of 832 adolescents. Exploratory and Confirmatory factor analyses were carried out for successive versions of 64, 37, 24 and 23 items. The theoretical four-factor structure of the 64-item version is not replicated in a factor analysis through principal axis extraction with direct oblimin rotation. The "Favoring Subject" factor was not found. 37 items present loadings equal to or larger than 0.30 for the "Rejection", "Emotional Warmth" and "Overprotection" factors. A re-analysis of these items shows a clear three-factor structure. When Arrindell et al .'s (1999 ) 23-item version was analysed, the three expected factors were also found. Confirmatory factor analyses allow us to reduce the 36-item version to a shorter one of 24 items. This last version achieves the best fit to data, including the 23-item version. The new 24-item version improves the construct validity of the EMBU and presents similar reliability coefficients.     

Factor analysis of MCMI-II and PACL basic personality scales in a college sample

This study examined factor dimensions common to the eight basic personality scales of the Millon Clinical Multiaxial Inventory-II (MCMI-II; Millon, 1987) and Personality Adjective Check List (PACL; Strack, 1987, 1990). Subjects were 140 college students (65 men and 75 women). MCMI-II weighted raw scores (WRS) and WRS corrected for number of items endorsed true by regression were employed for analysis along with PACL T-scores. Principal components analyses with varimax and direct oblimin rotations were carried out separately on the two sets of MCMI-II and PACL scores. MCMI-II and PACL scales measuring the same personalities were usually correlated most highly with each other, although some divergences were noted. WRS yielded three bipolar dimensions and a fourth unipolar method factor that loaded only the five MCMI-II scales that were strongly correlated with number of items endorsed true. Residual scores yielded a more meaningful set of three bipolar dimensions labeled Social Introversion-Extraversion, Emotionality-Restraint, and Social Dominance-Submissiveness, without the method factor, that were very similar to personality dimensions found separately in the two tests. More research is needed to clarify the response bias issue in the MCMI-II and to further explicate similarities and differences between the MCMI-II and the PACL.     

Factor Analysis of MCMI-II and PACL Basic Personality Scales in a College Sample

More research is needed to clarify the response bias issue in the MCMI-II and to further explicate similarities and differences between the MCMI-II and the PACL.     

Why do measures of normal and disordered personality correlate? A study of genetic comorbidity

The genetic and environmental correlations between measures of normal (NEO-FFI) and abnormal personality (Dimensional Assessment of Personality Pathology: DAPP-BQ) were estimated in a sample of 545 volunteer general population twin pairs (269 monozygotic and 276 dizygotic pairs). The largest genetic correlations were observed between the 18 DAPP-BQ dimensions and NEO-FFI neuroticism (range = .05 to .81; median = .48), extraversion (range = -.65 to .33; median = -.28), agreeableness (range = -.65 to .00; median = -.38), and conscientiousness (range = -.76 to .52; median = -.31). The smallest genetic correlations were found between the DAPP-BQ dimensions and NEO-FFI openness (range = -.17 to .20; median = -.04). The environmental correlations are lower in magnitude but show the same pattern of correlations between DAPP-BQ and NEO-FFI scales. These results indicate that these two scales share a common broad-based genetic architecture, whereas the environmental influences show greater scale specificity.     

“Authoritarianism” and Agreement with Things Authoritative

The use of personality and attitudinal questionnaires in private executive and military samples is briefly reviewed. The need for evidence regarding the factor similarity of such questionnaires in comparative studies is noted. Such a comparative factorial study of an abbreviated version of the Shure-Meeker (11) Personality/Attitude Schedule (PAS) is reported. In terms of the general scales examined, three of the four scales emerge in both samples. The order of emergence, as well as the number and item content of the factors, differs slightly between the two samples. Caution is suggested in assuming factor similarity across samples in comparative studies utilizing the PAS and other personality and attitudinal instruments.     

Reexamination of the Bem Sex-Role Inventory: The Interpersonal BSRI

The 40 masculine and feminine items of 746 Bern Sex-Role Inventory (BSRI; Bern, 1974) were subjected to a principal axis factor analysis with varimax rotation. Results revealed a four-factor solution, indicating that the original BSRI items do not provide two unidimensional ratings of femininity and masculinity. However, some support is given to Bern's initial two-factor thesis in that two principal factors emerged: one consisting of items that were originally identified as feminine, the other consisting of items that were originally identified as masculine. Content examination of the two principal factors resulted in an interpretation of the factors as Interpersonal Sensitivity and Interpersonal Potency. Internal consistency and validity of these two scales were examined and found to be adequate.     

Stability of the factor structure of Barrat's Impulsivity Scales for children across cultures: a comparison of Spain and Colombia

Despite the great importance of impulsivity in many childhood and adolescence disorders, there are few self-reports on child impulsivity. Recently, a modified version of Barratt's BIS-11 questionnaire adapted for children has been developed, which may be useful in assessing this personality dimension. The present study reports an adaptation of this questionnaire in a different culture (Colombia) and assesses the degree of convergence between the factor structures of both adaptations using consensus oblimin rotation. The results indicate not only that the factor structure of the test remains stable across both adaptations, and that two of the three scales in the Colombian version show acceptable reliabilities, but also that cultural and linguistic issues are important in test adaptation even when the same language is used.     

Effect of inapplicable items in the factor structure of the Spanish version of the Ways of Coping Questionnaire

The aim of this work was to examine how the presence of inapplicable items might change the factor structure of the 1984 Ways of Coping Questionnaire by Lazarus and Folkman. The Spanish version of the Ways of Coping Questionnaire was administered to 156 subjects with university degrees. The 95 women and 61 men whose ages were from 18 and 45 years (M = 27.8, SD = 12.1) were of middle socioeconomic status. All were residents of Buenos Aires. To study whether relevant items modify the factor structure of the Ways of Coping Questionnaire, two factor analyses were carried out, one with items rated as not relevant (Item Mean) and the other with the same items rated as not chosen. In both factor analyses, principal axes method and oblimin rotation were performed, and five factors were considered. Congruence indexes were performed. Analysis showed that not choosing an item because it does not coincide with one's behavior or ideas is not the same as not selecting that item because it does not apply to the current threatening situation. Lack of discrimination between situations when analyzing data leads to a distorted interpretation of the way in which the subject actually behaves or copes with the situation.     

Bryant's Empathy Index for children and adolescents: psychometric properties in the Spanish language

The present study investigated the following issues: (1) the structure of Bryant's Empathy Index for children and adolescents in a Spanish sample of 408 boys and 424 girls (M age=14.4 yr.), and (2) sex differences, including effect sizes and internal consistency of the scale. A principal components factor analysis with oblimin rotation showed that 20 of the index's 22 items load on three robust factors, related to Feelings of Sadness, Understanding Feelings, and Tearful Reaction with regard to the emotions of others. The 3-factor structure obtained an adequate fit to the data in the confirmatory factor analysis. Coefficients alpha ranged between .72 and .78. The 3 factors accounted for 42% of variance. As expected, girls scored higher than boys. It was concluded that the Spanish version of Bryant's Empathy Index has an acceptable reliability and construct validity, making it useful for research.     

The HEXACO model of personality structure and indigenous lexical personality dimensions in Italian,Dutch, and English

We correlated the scales of the HEXACO Personality Inventory (HEXACO-PI) with adjective scale markers of personality factors previously obtained in indigenous lexical studies of personality structure in the Italian, Dutch, and English languages. Self-ratings were obtained from samples of 327 Italian, 161 Dutch, and 214 English-speaking Canadian participants. Results showed that each of the six HEXACO variables—including Honesty–Humility—correlated strongly with its hypothesized six-factor adjective scale counterpart in all three languages. In each case, convergent correlations were substantially stronger than discriminant correlations. Because the HEXACO model was developed without prior knowledge of the indigenous Dutch and English lexical factors, the results suggest that the HEXACO model of personality structure can be extended to the personality lexicons of those languages.     

The predictive power of Cattell's personality questionnaires: An eighteen month prospective study

An 18 month prospective study of personality traits (as assessed by Cattell's Children's Personality Questionnaire and Sixteen Personality Factor Questionnaire) was conducted on twin pairs and their parents. The primary personality trait scores for both the adults and children had relatively low stability over the 18 month interval; in addition, in some cases, the inter-factor stability coefficients exceeded the intra-factor coefficients. This finding, coupled with the lack of parent/offspring similarity for the primary personality traits, places in question the predictive power of Cattell's personality questionnaires. A factor analysis on the original items indicated that 5 oblique factors for the children and 6 oblique factors for the adults need be retained. These factors were not only more stable than the primary trait scores, but they also did not have such high inter-factor stability coefficients. Except for Neuroticism and IQ, the adult and juvenile factors do not show structural similarities.
