RESUMO

When considering dyadic data, one of the questions is whether the roles of the two dyad members can be considered equal. This question may be answered empirically using indistinguishability tests in the actor-partner interdependence model. In this paper several issues related to such indistinguishability tests are discussed: the difference between maximum likelihood and restricted maximum likelihood based tests for equality in variance parameters; the choice between the structural equation modelling and multilevel modelling framework; and the use of sequential testing rather than one global test for a set of indistinguishability tests. Based on simulation studies, we provide guidelines for best practice. All different types of tests are illustrated with cross-sectional and longitudinal data, and corroborated with corresponding R code.

RESUMO

Personality disorders (PDs) are inherently associated with deficits in relating to other people. Previous research has shown consistent negative associations between categorical PD symptoms and relationship satisfaction. The present studies extend on these findings by examining the role of maladaptive traits in a number of ways. Self- and partner-reported maladaptive traits of both partners are included. Moreover, the present studies add a couple-centered approach by investigating the effects of actual similarity, perceptual similarity, and perceptual accuracy of the maladaptive trait profile on relationship satisfaction. PDs are conceptualized using 2 dimensional maladaptive trait models, that is, the Dimensional Assessment of Personality Pathology-Basic Questionnaire in Study 1 and the Personality Inventory for DSM-5 in Study 2. A total of 167 heterosexual couples participated in Study 1 and 52 heterosexual couples in Study 2. The actor-partner interdependence model was used to examine the associations between traits and relationship satisfaction, whereas the coefficient of profile agreement was used for the couple-centered analyses. Overall, results showed that the presence of maladaptive traits within romantic relationships has a detrimental effect on relationship satisfaction. Self-ratings on maladaptive traits, how we perceive our partners, and how we are perceived by our partners on maladaptive traits make significant contributions to our relationship (dis)satisfaction. Among the maladaptive traits, negative affect and detachment were most consistently negatively associated with relationship satisfaction. The couple-centered perspective showed less explanatory value but nontrivial associations between perceptual similarity and relationship satisfaction were found in Study 2.

RESUMO

The present study addresses the psychometric properties of the English version of the Dimensional Personality Symptom Item Pool (DIPSI), a comprehensive taxonomy of trait-related symptoms in childhood. The structural invariance of the English DIPSI and the original Flemish version was investigated in a large sample of Canadian (n = 341) and Flemish (n = 509) adolescents, using both self- and maternal ratings. The original 4-factor structure of the DIPSI, including the dimensions Emotional Instability, Disagreeableness, Introversion, and Compulsivity, was replicated in the Canadian sample across informants. Results provided support for metric invariance across the English and Flemish DIPSI version, indicating that associations between variables across samples can be confidently made, although the meaning of specific items may slightly differ across the different DIPSI versions. Across raters, the Flemish and English DIPSI dimensions showed a similar covariation pattern with internalizing and externalizing psychopathology. High intercorrelations between the DIPSI dimensions in both the Flemish and English version suggest low discriminant validity, potentially resulting from lower variance on personality pathology in general populations, from a general pathology factor, or from developmental issues. To conclude, the English version of the DIPSI can be considered a promising tool for assessing maladaptive traits in younger age groups in internationally oriented research designs.

RESUMO

The current study investigated how the Callous-Unemotional (CU) trait specifier is empirically associated with the proposed trait system for personality pathology in DSM-5, and addressed the use of multiple raters in the assessment of CU traits and additional maladaptive traits in an adolescent community sample. Both mothers and adolescents (N = 197) participated in the present study. Results showed that CU traits are located in different parts of the personality space, and are significantly associated with four broad maladaptive trait dimensions, Negative Affect, Detachment, Antagonism, and Disinhibition. Despite moderate agreement between raters, self- and maternal-rated CU traits were related in a congruent manner with PID-5 traits, and adolescents provided incremental information in CU trait assessment above maternal ratings. The present results have clear implications for the conceptualization of CU traits within the overarching model of personality pathology, proposed in DSM-5, and partially supported the application of a multi-informant approach in CU trait assessment.

RESUMO

Emotional dysregulation in childhood has been associated with various forms of later psychopathology, although no studies have investigated the personality related adolescent outcomes associated with early emotional dysregulation. The present study uses a typological approach to examine how the child behavior checklist-dysregulation profile (CBCL-DP) predicts DSM-5 pathological personality traits (as measured with the personality inventory for the diagnostic and statistical manual of mental disorders 5 or PID-5 by Krueger et al. (Psychol Med 2012)) across a time span of 4 years in a sample of 243 children aged 8-14 years (57.2 % girls). The results showed that children assigned to the CBCL-DP class are at risk for elevated scores on a wide range of DSM-5 personality pathology features, including higher scores on hostility, risk taking, deceitfulness, callousness, grandiosity, irresponsibility, impulsivity and manipulativeness. These results are discussed in the context of identifying early manifestations of persistent regulation problems, because of their enduring impact on a child's personality development.

RESUMO

The present study constructed empirically derived subtypes of adolescent offenders based on general traits and examined their associations with psychopathology and psychopathic traits. The sample included 342 detained minors (172 boys and 170 girls; mean age 15.85 years, SD = 1.07) recruited in various Youth Detention Centers across the Flemish part of Belgium. All adolescents provided self-reports on the quick big five, the youth self report, and the youth psychopathic traits inventory to assess general traits, psychopathology, and psychopathic traits respectively. Latent class analyses based on general personality traits were performed and suggested three personality types, consisting of an emotionally labile, close-minded and goal-oriented class, an undercontrolled class, and an emotionally labile-careless class. These three personality types within detained minors showed particular constellations of general traits and differed meaningfully in terms of their mean-scores on externalizing psychopathology and psychopathy measures.

RESUMO

OBJECTIVE: Relatively few data are available concerning the relations between hyperventilation symptoms and general personality traits in clinical populations. A clear picture of the personality traits associated with hyperventilation symptoms could enhance early detection of those individuals who are at risk for developing hyperventilation. The aim of this study was to investigate the role of general personality in hyperventilation syndrome. METHOD: Patients (N = 364) with symptoms not explained by an organic disease and supposedly caused by hyperventilation completed the NEO Five-Factor Inventory, the General Health Questionnaire--12, and the Nijmegen Questionnaire. Patients were also subjected to a hyperventilation provocation test and transcutaneous carbon dioxide (TcPCO(2)) values were registered. RESULTS: The results showed that patients with hyperventilation obtained mean Neuroticism scores above the normative mean. Moreover, only Neuroticism was positively linked with self-reported hyperventilation symptoms, and personality traits were more strongly related to self-reported complaints than to objective physical information. Neuroticism clearly differentiated between different diagnostic groups on the basis of Nijmegen Questionnaire and TcPCO(2) values, and an additional small effect of Agreeableness was observed. CONCLUSIONS: The present study contributes to the evidence that Neuroticism is strongly associated with self-reported hyperventilation symptoms, and provides substantial evidence that Neuroticism is a vulnerability factor in the development of hyperventilation. Therefore, personality assessment may be helpful in advancing the understanding and the early detection of hyperventilation symptoms.

RESUMO

Associations between callous-unemotional traits and general and maladaptive personality dimensions are examined in adolescence. More specifically, it was investigated to what extent general and maladaptive personality dimensions can account for the variance in callous-unemotional (CU) scores. Adolescents (N = 509) and their mothers completed the Inventory of Callous-Unemotional Traits (ICU; Frick, 2003), the Hierarchical Personality Inventory for Children (HiPIC; Mervielde & De Fruyt, 1999, 2002), and the Dimensional Personality Symptom Item Pool (DIPSI; De Clercq, De Fruyt, Van Leeuwen, & Mervielde, 2006). Both personality measures accounted for substantial variance in ICU scores and the overall CU profile in terms of the HiPIC and DIPSI was consistent with psychopathy conceptualizations and consistent across informant. Implications for the assessment of early externalizing trait pathology are discussed.

RESUMO

The present study examines the associations between anger and general and maladaptive traits in a combined forensic psychiatric and community sample of men. Thirty-four male forensic psychiatric patients and 219 men from the general population completed the Novaco Anger Scale (NAS; Novaco, 1994), the NEO-PI-R (Costa & McCrae, 1992), the ADP-IV (Schotte & De Doncker, 1994) and the VKP (Duijsens, Haringsma, & EurelingsBontekoe, 1999) at two measurement occasions with a one-year interval. The results of a series of multiple regression analyses showed that general and maladaptive traits accounted for a substantial amount of variance in anger scores. Neuroticism, Agreeableness and Externalizing traits were most prominent in the prediction of anger, while Conscientiousness was acting as a suppressor variable in the regression models. Strengths and limitations of the present study and implications for further research and clinical practice are discussed.

RESUMO

The tripartite model (in Clark and Watson, J Abnorm Psychol 100:316-336, 1991) comprises Negative Affect (NA), Positive Affect (PA), and Physiological Hyperarousal (PH), three temperamental-based dimensions. The current study examined the tripartite model's assumptions that (a) NA interacts with PA to predict subsequent depressive (but not anxiety) symptom developments and (b) NA interacts with PH to predict subsequent anxiety (but not depressive) symptom developments in a sample of 243 community and referred children and adolescents (42.8% boys; M age = 10.87 years, SD = 1.83). Results confirmed that individuals with a combined high NA/low PA profile display the least favorable course of depressive -but not anxiety- symptoms. In contrast with the model, the combination of NA and PH influenced the development of depression, but not anxiety. Relations were not moderated by sex or sample. Results revealed that the assessment of the tripartite components is warranted as it can help to identify children at risk for an unfavorable depressive symptom course.

RESUMO

In literature, there exists disagreement regarding the impact of comorbid personality disorder(s) (PD[s]) on treatment outcome for patients with major depressive disorder (MDD). The aim of this paper was to investigate whether statistical heterogeneity and inter-dependency are potential moderators of the effect of co-morbid PDs on outcome for patients with MDD. Clinician-rated MADRS scores and DSM-IV Axis II personality disorder diagnoses were obtained from 562 outpatients with MDD who received 6 months of combined psycho- and pharmacotherapy. Single-level regression showed significantly worse treatment outcome among patients with co-morbid PD, as compared to patients with no PD. After controlling for statistical heterogeneity and interdependency, treatment outcome was no longer significantly worse for patients with co-morbid PD. In conclusion, heteroscedasticity and inter-dependency should be considered as potentially compelling explanations for inconsistencies in findings on treatment outcome for depressed patients with co-morbid PDs.

RESUMO

Using a combined sample (N=1,215) of referred children and children from the general population aged between 8 and 14 years, the present study addressed two research goals: First, latent mean differences (depending on the individual's sex or psychopathology level) in anxiety, depression, Positive Affect (PA), Negative Affect (NA) and Physiological Hyperarousal (PH) were examined. Secondly, the structure of anxiety and depression was investigated from a tripartite model perspective in boys and girls with high versus low levels of psychopathology respectively. When relating the latent mean level differences in NA, PA, and PH with those in anxiety and depression, the results suggest that higher levels (depending on the individual's sex and psychopathology status) of anxiety or depression are associated with higher levels of PH and lower levels of PA, whereas no consistent pattern was found between mean level differences in NA on the one hand and mean level differences in anxiety/depression on the other. Results further demonstrated that a better fit was obtained for the dual than for the unitary construct representation in boys or girls with high or low levels of psychopathology, thereby suggesting that a valid distinction can be made between anxiety and depression in children between 8 and 14 years old, irrespective of their sex or level of psychopathology. However, when looking at the structural relations of the dual construct representation of anxiety and depression with NA, PA and PH in each of the four groups separately, it became evident that the PH and PA tripartite dimensions could not account for the unique aspects of anxiety and depression respectively. Moreover, PH rather than NA was found to be common for anxiety and depression.

RESUMO

Psychometric properties of the Dutch version of the Affect and Arousal Scales (AFARS) were inspected in a combined clinical and population sample (N = 1,215). The validity of the tripartite structure and the relations between Negative Affect, Positive Affect, and Physiological Hyperarousal (PH) were investigated for boys and girls, younger (8-11 years) and older (12-14 years) children, and for children with high versus low levels of emotional/behavioral problems separately. Results demonstrated an adequate fit of the tripartite structure in each of the subgroups. Multigroup confirmatory factor analysis demonstrated parameter equivalence across sex, age, and psychopathology status. Furthermore, the assumption of invariant error variances of the indicator variables was tenable across sex, age, and psychopathology status. Invariant variances and covariances of the latent constructs (i.e., the tripartite factors) were supported across sex and psychopathology status but not across age. Finally, adequate item and scale properties and good convergent and moderate divergent validity of the Dutch AFARS subscales were demonstrated, except for the divergent validity of the PH subscale.

RESUMO

Miller and colleagues (Miller, Bagby, Pilkonis, Reynolds, & Lynam, 2005) recently developed a Five-Factor Model (FFM) personality disorder (PD) count technique for describing and diagnosing PDs and psychopathy in adulthood. This technique conceptualizes PDs relying on general trait models and uses facets from the expert-generated PD prototypes to score the FFM PDs. The present study corroborates on the study of Miller and colleagues (2005) and investigates in Study 1 whether the PD count technique shows discriminant validity to describe PDs in adolescence. Study 2 extends this objective to psychopathy. Results suggest that the FFM PD count technique is equally successful in adolescence as in adulthood to describe PD symptoms, supporting the use of this descriptive method in adolescence. The normative data and accompanying PD count benchmarks enable to use FFM scores for PD screening purposes in adolescence.

RESUMO

The present study investigates five types of continuity of personality and internalizing and externalizing problems (i.e., structural, differential, mean-level, individual-level and ipsative continuity) in a sample of referred children and adolescents (N = 114) with a broad variety of psychological problems. Mothers were administered a child personality and psychopathology measure, i.e., the Hierarchical Personality Inventory for Children [Handleiding hiërarchische persoonlijkheidsvragenlijst voor kinderen (manual hierarchical personality inventory for children). Ghent University, Department of Developmental, Personality, and Social Psychology, Ghent, 2005] and the Child Behavior Checklist [Handleiding voor de cbcl/4-18: (Manual of the CBCL/4-18), Afdeling Kinder- en Jeugdpsychiatrie. Erasmus Universiteit Rotterdam, The Netherlands, 1996] at two measurement occasions, with a 26-months interval. Personality was substantially stable, paralleling findings for non-referred peers. Internalizing and Externalizing Problem Behavior were almost as stable as personality traits, suggesting that childhood psychopathology is more persistent than generally assumed. Strengths and limitations of the present study and implications for further research are discussed.

RESUMO

The validity of DSM-IV predictions [Widiger, T. A., Trull, T. J., Clarkin, J. F., Sanderson, C. J., & Costa, P. T., (2002). A description of the DSM-IV personality disorders with the five-factor model of personality. In Costa, P. T. & Widiger, T. A. (Eds.), Personality disorders and the five-factor model of personality (2nd ed.). Washington DC: American Psychological Association] concerning Antisocial Personality Disorder and the validity of the hypothesized associations between the Five-Factor Model and psychopathy were examined in 48 male forensic-psychiatric patients. Prevalence of psychopathy and comorbid personality pathology was also investigated, as well as the convergent validity of two Dutch personality disorder inventories. Patients provided self-descriptions on the NEO-PI-R [Costa, P. T., & McCrae, R. R., (1992b). Professional Manual: Revised NEO Personality Inventory (NEO-PI-R) and NEO Five-Factor-Inventory (NEO-FFI). Odessa, FL: Psychological Assessment Resources], and were administered the VKP [Duijsens, I. J., Haringsma, R., & EurelingsBontekoe, E. H. M., (1999). Handleiding VKP (Vragenlijst voor kenmerken van de persoonlijkheid). Gebaseerd op DSM-IV en ICD-10. Leiderdorp: Datec] and the ADP-IV [Schotte, C. K. W., & De Doncker, D. A. M., (1994). ADP-IV Questionnaire. Antwerp Belgium: University Hospital Antwerp] to assess personality pathology. Psychopathy was assessed using Hare's Psychopathy Checklist-Revised (PCL-R; [Hare, R. D., (1990). The Hare Psychopathy Checklist Revised Manual. Toronto: Multi-Health Systems]) based on a semi-structured interview and file records of psychiatric and psychological evaluations and criminal history. Results underscored the validity of the FFM Antisocial PD associations, but the hypothesized correlations between the FFM and Psychopathy were less supported. Results supported the convergent validity of the ADP-IV and the VKP, both at the dimensional and categorical level. Around 55% met the diagnostic threshold of psychopathy, and Antisocial PD was the most prevalent disorder in the psychopathic group, consistent with previous research. Sizeable personality comorbidity was also observed.

RESUMO

This study examines 5 types of personality continuity--structural, mean-level, individual-level, differential, and ipsative--in a representative population (N=498) and a twin and sibling sample (N=548) of children and adolescents. Parents described their children on 2 successive occasions with a 36-month interval using the Hierarchical Personality Inventory for Children (I. Mervielde & F. De Fruyt, 1999). There was evidence for structural continuity in the 2 samples, and personality was shown to be largely differentially stable. A large percentage had a stable trait profile indicative of ipsative stability, and mean-level personality changes were generally small in magnitude. Continuity findings were explained mainly by genetic and nonshared environmental factors.
