Assessing the DSM-IV structure of personality disorder with a sample of Chinese psychiatric patients

The validity of the three-cluster system of personality disorders (PDs) in the latest version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; APA, 1994) was examined in a sample of Chinese psychiatric patients (n = 227), who completed the self-report Personality Disorders Questionnaire for DSM-IV (PDQ-4; Hyler, 1994) and who were also administered the clinician-rated Personality Disorders Interview-IV (PDI-IV; Widiger, Mangine, Corbit, Ellis, & Thomas,). Using confirmatory factor analysis, a three-factor model corresponding to the DSM-IV clusters was tested and compared statistically to a one-factor model and a set of random, three-factor models. Only the clinician-rated instrument supported the DSM-IV three-cluster model, and then only when the factors were allowed to correlate. Results from the theoretically more rigorous uncorrelated model testing did not support the DSM-IV model for either assessment modality.     

Capturing the four-factor structure of psychopathy in college students via self-report

A number of self-report psychopathy scales have been used successfully in both clinical and nonclinical settings. However, their factor structure does not adequately capture the four factors (Interpersonal, Affective, Lifestyle, and Antisocial) recently identified in the Psychopathy Checklist-Revised (PCL-R; Hare, 2003) and related measures. This deficit was addressed by upgrading the Self Report Psychopathy Scale (SRP-II; Hare, Hemphill, & Harpur, 1989). In Study 1 (N = 249), an exploratory factor analysis of this experimental version revealed oblique factors similar to those outlined by Hare (2003). In Study 2 (N = 274), confirmatory factor analysis (CFA) confirmed this structure, that is, four distinct but intercorrelated factors. The factors exhibited appropriate construct validity in a nomological network of related personality measures. Links with self-reports of offensive activities (including entertainment preferences and behavior) also supported the construct validity of the oblique four-factor model.     

Confirmatory factor analysis of the WPPSI for language-impaired children

The present study used a maximum-likelihood confirmatory factor analysis (CFA) to test the hypothesis that a four-factor model is the most parsimonious explanation of the structure of the WPPSI for language-impaired children. Four separate maximum-likelihood confirmatory factor analyses were performed on a sample of 198 Norwegian language-impaired children tested with the WPPSI, and on the Norwegian (n = 563) and American (n = 1200) standardization samples. A one-factor (general), a two-factor (verbal and performance), three-factor (parallel to the WISC-R) and a four-factor solution composed of "processing dependent" ("knowing how" and "seeing how") and "knowledge dependent" ("knowing that" and "seeing that") were imposed on the average intercorrelation matrices of the 11 WPPSI subtests. Confirmatory factor analysis indicated that the four-factor latent construct model was the most parsimonious explanation of the structure of the WPPSI for language-impaired children, as well as for normally developing children.     

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 confirmatory factor analysis of the structure of schizotypy

Recent research into schizotypal traits has been concerned with the number and nature of these personality dimensions. Earlier exploratory factor analytic work using a wide variety of scales (the CSTQ) has generated a four-factor solution but other solutions have been provided by other investigators. This study uses confirmatory factor analysis on a large sample to compare several plausible models of the relationships between scales. These models include a two-factor model separating ‘positive’ from ‘negative’ schizotypal features, a three-factor model including features of cognitive disorganization, and the four-factor model generated previously by exploratory factor analysis. Results offer support for the four-factor solution as the only structure meeting multiple criteria for goodness of fit. The relevance of Eysenck's dimensions, and the P scale in particular, to the results is discussed. Attention is drawn to the possibility that the factors describe predispositions of risk of psychotic disorders beyond that of schizophrenia.     

The factor structure of the State-Trait Anxiety Inventory: an alternative view

Past studies of the factor structure of the State-Trait Anxiety Inventory (STAI; Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983) have arrived at various solutions. However, a relatively strong consensus supports a four-factor (State Anxiety Present, State Anxiety Absent, Trait Anxiety Present, and Trait Anxiety Absent) structure of the scale resulting from the combination of item polarity dimensions and the original two factors (State and Trait Anxiety). In this article, we assessed the adequacy of an alternative factor model of STAI data, the two-construct, two-method model, in three large samples using confirmatory factor analysis. The results revealed a statistical advantage of the two-construct, two-method model over the one-factor model, the two-construct factor model, and the four-factor model. We discuss possible interpretational advantages of the two-construct, two-method model of the STAI.     

Validation of the dimensional factor structure of the personality psychopathology five in clinical and nonclinical samples

Confirmatory factor analysis (CFA) was used to determine whether the latent structure underlying the items composing the MMPI-2 Personality Psychopathology Five scales (PSY-5; Harkness, McNulty, & Ben-Porath, 1995) is representative of the theoretical model that informed their construction. Results from the CFA revealed a good fit between the hypothesized five-factor model and the obtained latent factor structure in both clinical (n = 284) and nonclinical (n = 351) samples. Moreover, the PSY-5 model proved to be a better fit than a random five-factor model and a one-factor model. Correlations between the PSY-5 scales and a set of MMPI-2 (DSM-IV) personality disorder scales provided additional evidence of convergent and discriminant validity.

The joint structure of DSM-IV Axis I and Axis II disorders

The Diagnostic and Statistical Manual (4th ed. [DSM-IV]; American Psychiatric Association, 1994) distinction between clinical disorders on Axis I and personality disorders on Axis II has become increasingly controversial. Although substantial comorbidity between axes has been demonstrated, the structure of the liability factors underlying these two groups of disorders is poorly understood. The aim of this study was to determine the latent factor structure of a broad set of common Axis I disorders and all Axis II personality disorders and thereby to identify clusters of disorders and account for comorbidity within and between axes. Data were collected in Norway, through a population-based interview study (N = 2,794 young adult twins). Axis I and Axis II disorders were assessed with the Composite International Diagnostic Interview (CIDI) and the Structured Interview for DSM-IV Personality (SIDP-IV), respectively. Exploratory and confirmatory factor analyses were used to investigate the underlying structure of 25 disorders. A four-factor model fit the data well, suggesting a distinction between clinical and personality disorders as well as a distinction between broad groups of internalizing and externalizing disorders. The location of some disorders was not consistent with the DSM-IV classification; antisocial personality disorder belonged primarily to the Axis I externalizing spectrum, dysthymia appeared as a personality disorder, and borderline personality disorder appeared in an interspectral position. The findings have implications for a meta-structure for the DSM.     

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 overall autobiographical memory usage: the directive, self and social functions revisited

According to theory, autobiographical memory serves three broad functions of overall usage: directive, self, and social. However, there is evidence to suggest that the tripartite model may be better conceptualised in terms of a four-factor model with two social functions. In the present study we examined the two models in Danish and German samples, using the Thinking About Life Experiences Questionnaire (TALE; Bluck, Alea, Habermas, & Rubin, 2005), which measures the overall usage of the three functions generalised across concrete memories. Confirmatory factor analysis supported the four-factor model and rejected the theoretical three-factor model in both samples. The results are discussed in relation to cultural differences in overall autobiographical memory usage as well as sharing versus non-sharing aspects of social remembering.     

Exploring the structure of Zuckerman's Sensation Seeking Scale, Form V in a Spanish sample

The psychometric properties of the original version of the Sensation Seeking Scale (Form V) were analyzed in a sample of 1,006 Spanish university students. The total sample was randomly split into two halves. Exploratory factor analyses were conducted on the calibration sample (n=504), whereas confirmatory factor analysis procedures were performed on the validation sample (n=502). As previous studies have suggested, exploratory factor structure indicated that several items load on a different factor or have loadings lower than .30. Those problems were surpassed when the best five items per factor were factor analyzed again. The confirmatory factor analyses showed that a 4-factor simple structure model gave a clearly imperfect fit. A model of 20 items (5 items per factor) gave a better fit, although with similar problems regarding the low reliabilities of the Experience Seeking and Boredom Susceptibility subscales. The need for improvement of the four-factor structure is discussed.     

The cross-cultural generalizability of Axis-II constructs: an evaluation of two personality disorder assessment instruments in the People's Republic of China

We examined the reliability, cross-instrument validity, and factor structure of Chinese adaptations of the Personality Diagnostic Questionnaire (PDQ-4+; N = 1,926) and Personality Disorders Interview (PDI-IV; N = 525) in psychiatric patients. Comparisons with data from Western countries suggest that the psychometric properties of these two instruments are comparable across cultures. Low to modest agreement between the PDQ-4+ and PDI-IV was observed for both dimensional and categorical personality disorder evaluations. When the PDI-IV was used as the diagnostic standard, the PDQ-4+ showed higher sensitivity than specificity, and higher negative predictive power than positive predictive power. Factor analyses of both instruments replicated the four-factor structure O'Connor and Dyce (1998) found in Western samples. Results suggested that conceptions and measures of DSM-IV personality disorders are cross-culturally generalizable to Chinese psychiatric populations.     

Sixteen-item Anxiety Sensitivity Index: confirmatory factor analytic evidence, internal consistency, and construct validity in a young adult sample from the Netherlands

The present investigation examined the factor structure, internal consistency, and construct validity of the 16-item Anxiety Sensitivity Index (ASI; Reiss Peterson, Gursky, & McNally 1986) in a young adult sample (n = 420) from the Netherlands. Confirmatory factor analysis was used to comparatively evaluate two-factor, three-factor, and four-factor models of the anxiety sensitivity construct. Support was found for a hierarchical structure of anxiety sensitivity, with one global higher-order factor and four lower-order factors. Internal consistency for the global and lower-order factors of the 16-item ASI was adequate. Convergent and discriminant associations between the 16-item ASI and general mood and panic-specific variables were consistent with anxiety sensitivity theory. In addition, incremental validity of the anxiety sensitivity construct was established, relative to negative affectivity, for unexpected panic attacks and agoraphobic avoidance.

However, there is evidence to suggest that the tripartite model may be better conceptualised in terms of a four-factor model with two social functions. In the present study we examined the two models in Danish and German samples, using the Thinking About Life Experiences Questionnaire (TALE; Bluck, Alea, Habermas, & Rubin, 2005), which measures the overall usage of the three functions generalised across concrete memories. Confirmatory factor analysis supported the four-factor model and rejected the theoretical three-factor model in both samples. The results are discussed in relation to cultural differences in overall autobiographical memory usage as well as sharing versus non-sharing aspects of social remembering.     

MORE ON THE STRUCTURE OF MALE ROLE NORMS

This study assessed the structure of a widely used measure of masculinity ideology, the Male Role Norms Scale (Thompson & Pleck, 1986), using data from four samples of male college students (total N= 656) at two large, public universities (one Midwestern, one Eastern-Central). Exploratory factor analysis suggested a four-factor model best fit the data in the exploratory sample (sample 1; N = 210). The four factors were Status/ Rationality, Antifemininity, Tough Image, and Violent Toughness. A series of confirmatory factor analyses on a validation sample (samples 2, 3, and 4; N = 446), tested four models based on theory (i.e., Brannon, 1976) and previous research (i.e., Thompson & Pleck, 1986). Results from Study 1, our exploratory analysis, indicated that the four-factor model derived from the exploratory sample in Study 1 provided the best fit for the validation sample data of all models tested and also provided a good fit in absolute terms, according to several model-data fit indices. Implications for the assessment of masculinity ideology and suggestions for future research are discussed.     

A comparative assessment of the factor structures and psychometric properties of the GHQ-12 and the GHQ-20 based on data from a Finnish population-based sample

The General Health Questionnaire (GHQ) is a self-report questionnaire designed to identify psychological distress. Psychometric properties of two versions of GHQ-12 and GHQ-20 were assessed in a large population-based sample of Finnish twins, ages 22 to 27 (n= 4580). Participants were randomized into two subgroups, namely Twin1 (n= 2294) and Twin2 (n= 2286). The GHQ-12 data were assessed using Confirmatory Factor Analysis (CFA). The factor structure of the GHQ-20 was first assessed with Exploratory Factor Analysis (EFA) in the Twin1 dataset, and the results obtained were then subjected to CFA in Twin1 and Twin2 datasets. The CFA of the GHQ-12 indicated that the best fit and the simplest solution were provided by the three-factor solution in both subpopulations. Analyses of the GHQ-20 suggested that the four-factor structure was superior to the three-factor model. This result is also theoretically justifiable. Compared to the 12-item version, GHQ-20 provides additional fourth factor of anhedonia, suggesting some discriminative power.
