“…Higher scores indicate an increased presence of the associated characteristics. A Portuguese version of the NPI-13, especially adapted for use with adolescents, was used (Pechorro et al 2016c;Pechorro et al 2017). The internal consistency for the current study, estimated by Kuder-Richardson coefficient, was: NPI-13 total KR20 = .82; Leadership/Authority dimension KR20 = .75; Grandiose Exhibitionism dimension KR20 = .70; and Entitlement/Exploitativeness dimension KR20 = .60.…”

The association between psychopathic traits and antisociality among females is an important and understudied area of research. Drawing on 377 female adolescents (103 selected from forensic settings and 274 selected from school settings) from Portugal, the current study examined the psychometric properties of the Antisocial Process Screening Device Self-Report (APSD-SR) and Youth Psychopathic Traits Inventory-Short version (YPI-S) in female youth populations. When comparing these two measures the YPI-S revealed clearer results in terms of its three-factor structure and internal consistency, and stronger convergent validity coefficients. The APSD-SR revealed problems in terms of its factor structure and internal consistency of its Callous-Unemotional (CU) and Impulsivity dimensions. Convergent validity was demonstrated among these measures and with measures of other facets of the psychopathy construct (CU traits, narcissism) and related constructs (reactive and proactive aggression), and discriminant validity was found with a measure of basic empathy. Expected significant associations were found in terms of criterion-related validity with several indicators of delinquent careers including age of criminal onset, Conduct Disorder (CD), crime seriousness, violent crimes, alcohol use, and drug use. Keywords Psychopathic personality. Psychopathy measures. Female adolescents. Delinquency. Delinquent career Psychopathy, defined as a personality disorder that represents a suite of affective, interpersonal, and behavioral traits that create significant impairments in social functioning and impose high costs to society in terms of crime and criminal justice system expenditures. The prevalence of psychopathy among forensic and justice system-involved individuals is several times higher than the general population. Although the association between psychopathy and assorted antisocial conditions and behaviors is unequivocal (da Silva et al. 2012; DeLisi 2009; Hare 1993, 1996; Pechorro et al. 2016b), the strength and consistency of that relationship largely pertains to data derived from male, adult criminal offenders. The association between various psychopathy features and female antisociality, defined as the liability for involvement in conduct problems and antisocial behavior is more heterogeneous and the literature is replete with competing and at times contradictory findings (Nicholls and Petrila 2005; Vitale and Newman 2001). Certainly, studies have shown gender consensus in the linkages between psychopathy and a multitude of behavioral outcomes including: self-reported and teacher-rated aggression (Marsee et al. 2005), emotional processing (Kimonis et al. 2006), negative health outcomes (Beaver et al. 2014), and both self-reported physical and relational aggression (Penney and Moretti 2007). Together, these studies suggest that the

“…Internal consistency based on Cronbach's alpha has previously been reported as .66 for LA, .65 for GE, .51 for EE, and .73 for the NPI-13 total (Gentile et al 2013). The Portuguese version of the NPI-13 (Pechorro et al 2016b) was used. The internal consistency of the NPI-13 total for the current study, estimated by Kuder-Richardson coefficient, was .77.…”

Few personality traits are as socially relevant as impulsivity, but few self-report measures have been specifically developed for adolescents and children. The aim of the present study was to examine the psychometric properties of the Barratt Impulsiveness Scale version 11 (BIS-11) among a mixed-gender sample of 782 Portuguese youth (M = 15.87 years; SD = 1.72), in a school context. Confirmatory factor analysis revealed the expected 6-factor first-order structure, but the 3-factor second-order factorial structure did not present a good fit. Cross-gender measurement invariance was demonstrated only in terms of weak invariance. Nonetheless, the Portuguese adaptation of the BIS-11 demonstrated some generally acceptable psychometric properties of internal consistency, mean interitem correlation, convergent validity, discriminant validity, and criterion-related validity of statistically significant associations with conduct disorder symptoms, alcohol abuse, drug use, and unprotected sex. The use of the BIS-11 among the male and female youth population is psychometrically justified, and it can be a useful measure to identify impulsive adolescents who are at considerable risk of personal injury and present a potential source of injury to others.

Research on adolescent aggression often distinguishes between reactive and proactive aggression, but there is limited knowledge regarding the application or measurement of these subtypes of aggression among female youth, especially forensic samples of female youth. Drawing on 377 girls (103 selected from forensic settings and 274 selected from school settings) from Portugal, the current study is the first to simultaneously examine the psychometric properties of the Reactive-Proactive Aggression Questionnaire (RPQ) in incarcerated girls and community girls. The results support the use of the RPQ in terms of its two-factor structure, measurement invariance, internal consistency, convergent validity, discriminant validity, and known-groups validity. Significant associations were found with several criterion-related variables such as age of criminal onset, age of first problem with the law, conduct disorder, crime severity, violent crimes, and alcohol and drug use. Findings are discussed in terms of the use of the RPQ among incarcerated girls and community girls.
