- Confirmatory analysis of the Parenting Styles and Dimensions Questionnaire (PSDQ) short form in a portuguese samplePublication . Martins, Cátia; Ayala Nunes, Lara; Nunes, Cristina; Pechorro, Pedro; Costa, Emília; Matos, FilomenaAn important research field in family studies relates to the role parenting practices can have on several domains of children's development. Regarding to parenting styles, it was Baumrind's conceptualization that was responsible for a relevant research boost in this area. She proposed a model contemplating three different styles: authoritative, authoritarian, and permissive. The aim of our study was to examine the factor structure, internal consistency and others psychometric properties of the Portuguese version of the Parenting Styles and Dimensions Questionnaire (PSDQ). The participants were 424 parents (mainly mothers, 81.2%) from Algarve (South of Portugal), that answered to PSDQ and a sociodemographic questionnaire. The instrument comprises 32 items: 12 questions regarding the authoritative style, 15 questions regarding the authoritarian style, and 5 questions regarding the permissive style. Several competing models (i.e., one and three-factorial, and another where latent variables were organized in a 1st and 2nd order factors) were tested in regards to PSDQ factor structure using confirmatory factor analysis. A fourth model, contemplating inter-correlations between item 7 and 8 was also proposed, which showed adequate fit and internal consistency. These findings support the PSDQ original structure. Implications concerning the use and contributes to social and emotional child' adjustment are discussed.
- Análise psicométrica das escalas de defensividade e validade do Weinberger Adjustment InventoryPublication . Pechorro, Pedro; Nunes, Cristina; Paulino, Mauro; R. Simões, MárioO presente artigo tem como principal objetivo examinar as propriedades psicométricas das escalas de defensividade e de validade do Inventário de Ajustamento de Weinberger (Weinberger Adjustment Inventory - WAI) numa amostra de jovens adultos portugueses (N=610, M=21.33 anos, DP=3.09) provenientes de meio universitário. Os resultados da análise fatorial confirmatória indicaram a presença de uma estrutura tridimensional com um bom ajustamento. As escalas de defensividade e de validade do WAI demonstraram propriedades psicométricas adequadas, nomeadamente ao nível de fiabilidade e de validade convergente, discriminante e de critério. Tais resultados apoiam a utilização das escalas de defensividade e validade do WAI na investigação e avaliação psicológica de jovens adultos portugueses.
- Dark triad psychopathy outperforms self-control in predicting antisocial outcomes: a structural equation modeling approachseabreamPublication . Pechorro, Pedro; Curtis, Shelby; DeLisi, Matt; Maroco, João; Nunes, CristinaDark Triad traits and self-control are considered viable causal precursors to antisocial and criminal outcomes in youth. The purpose of the present study is to concurrently compare how Dark Triad traits and self-control differ in terms of predicting self-reported juvenile delinquency, CD symptoms, proactive overt aggression, and crime seriousness. The sample consisted of 567 (M = 15.91 years, SD = 0.99 years, age range = 14–18 years) Southern European youth from Portugal. Structural-equation-modelling procedures revealed that the psychopathy factor of Dark Triad traits presented the strongest significant hypothetical causal associations with the antisocial/criminal outcomes, followed by self-control. Machiavellianism and narcissism presented the lowest causal associations. Our findings indicate that psychopathy, as operationalized in the Dark Triad, concurrently surpasses self-control and the remaining factors of the Dark Triad in terms of predicting antisocial/criminal outcomes in youth. This suggests that behavioral disinhibition, or a core incapacity to regulate one’s conduct, is central for understanding delinquency and externalizing psychopathology. Comparatively, the interpersonal component of dark personality features, such as Machiavellianism and narcissism, are secondary for understanding crime.
- Psychopathy and behavior problems: a comparison of incarcerated male and female juvenile delinquentsPublication . Pechorro, Pedro Santos; Vieira, Duarte Nuno; Poiares, Carlos Alberto; Vieira, Rui Xavier; Maroco, Joao; Neves de Jesus, Saul; Nunes, CristinaThe objective of the present study was to compare incarcerated male and female juvenile offenders regarding psychopathic traits, behavior problems, psychopathy taxon, conduct disorder, self-reported delinquent behavior, and crime seriousness. Within a total forensic sample of 261 detainee participants, subdivided in a male group (n = 217) and a female group (n = 44), statistically significant differences were found. Female juvenile offenders show less callous-unemotional traits, more emotional symptoms, more prosocial behaviors, less self-reported delinquent behavior, and lower crime seriousness. Conduct disorder prevalence was very high, but no statistically significant gender differences were found. The predictive importance of psychopathic traits, behavior problems, psychopathy taxon, and conduct disorder for the prediction of group membership (female versus male) was established by binary logistic regression.
