This study aims to test the psychometric properties of the Violent Risk Scale (VRS) in a sample of Portuguese remand prisoners. A total of 133 subjects participated in the present study. We carried out a Confirmatory Factor Analysis (CFA) to test the originally proposed two factor structure. Results showed evidence to support the VRS's psychometric qualities.The CFA tested the two-factor structure and showed ev...
Introduction Non-suicidal self-injury (NSSI) and suicidal behavior (SB) co-occur and are usually framed in a self-harm continuum, being differentiated according to several factors, including suicidal intent (SI). The current study aims to clarify if SI is present when adolescents engage in NSSI and, in addition, if these behaviors’ severity and diversity predict the presence of SI when adolescents engage in NSS...
Neste capítulo, revisitamos as origens das medidas de autorrelato e analisamos as suas caraterísticas, confrontando-as com as das estatísticas oficiais. As medidas de autorrelato são um método de recolha de informação amplamente usado na Criminologia, cujas potencialidades e limitações devem ser conhecidas e ponderadas. ∙ No panorama nacional, abordamos os instrumentos de delinquência autorrevelada adaptados pa...
The present study aims to test the psychometric properties of the Portuguese version of the "How I Think" (HIT) questionnaire. The HIT questionnaire is a self-report measure of self-serving cognitive distortions. Our sample was comprised of 442 Portuguese-speaking adolescents and young adults (254 males and 188 females), aged between 12 and 20 years. Of the total 442 participants, 351 were recruited from a Port...
ObjectivesField experiments combine the benefits of the experimental method and the study of human behavior in real-life settings, providing high internal and external validity. This article aims to review the field experimental evidence on the causes of offending.MethodsWe carried out a systematic search for field experiments studying stealing or monetary dishonesty reported since 1979.ResultsThe search proces...
Although research on sensitive topics has produced a large body of knowledge on how to improve the quality of self-reported data, little is known regarding the sensitivity of offending questions, and much less is known regarding how topic sensitivity is affected by recall periods. In this study, we developed a multi-dimensional assessment of item sensitivity in order to assess and rank the sensitivity of offend...
Objectives Current knowledge about the causes of offending behavior is heavily reliant on self-reports of offending (SRO). However, methodological research on the impact of modes of administration on SRO is very scarce. Further, the existing evidence conflicts with the general knowledge about responding to sensitive questions. In this study, we aimed to test whether SRO are affected by modes of administration. ...
Psychopathy Checklist-Revised (PCL-R) is the gold standard for assessing psychopathy. However, its factorial structure has been subject of debate, and different factor models have been proposed. Furthermore, research has not focused on the PCL-R factorial structure among intimate partner violence (IPV) perpetrators. We analyzed and compared the fit of nine alternative models of PCL-R among a sample of 242 IPV p...
Research has recognized the importance of understanding the social representations about the functions of deliberate self-harm, particularly in the context of clinical intervention. In addition, parents can play a relevant role in the rehabilitation of adolescents with these behaviors. However, there are few studies that focused on the description and comparison of the social representations about these functio...
The relation between family and low self-control is usually studied within linear hypotheses. In this study, we intended to test the familial origin of self-control under a curvilinear hypothesis. This is a cross-sectional study, with a sample of 448 adolescents and young adults. Data analysis was based on correlation and regression-based statistics. Results revealed linear associations between family functioni...
