- Development and Factorial Validation of the Inventory of Deliberate Self-Harm Behaviours for Portuguese AdolescentsPublication . Duarte, Eva; Pereira, Maria Gouveia; Gomes, Hugo S.Deliberate self-harm (DSH) is a public health problem that mainly affects adolescents and young adults. Evidence suggests that multiple methods are used with a self-aggressive intent. The present article focuses on the development and factorial validation of the Inventory of Deliberate Self-harm Behaviours for Portuguese adolescents. This instrument assesses the lifetime frequency of 13 DSH methods, with and without suicidal intent. Study 1 consisted of an exploratory factor analysis with a sample of 131 adolescents with a reported history of DSH. Results revealed a three-factor structure with acceptable internal consistency: High Severity DSH, Mild Severity DSH, and Substance Use DSH. After item reduction, this structure was tested in Study 2 through a confirmatory factor analysis with an independent sample of 109 adolescents also with a history of DSH. Results showed an acceptable model fit. This instrument presents a solid structure and acceptable psychometric properties, allowing its use in further research.
- How do families represent the functions of deliberate self-harm? A comparison between the social representations from Adolescents and Their ParentsPublication . Duarte, Eva; Pereira, M. Gouveia; Gomes, Hugo S.; Sampaio, DanielResearch 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 functions, particularly in families. This article aimed to analyze the social representations about the functions of deliberate self-harm from adolescents and their parents. We developed two sets of analyses: first we compared the social representations from adolescents without a history of deliberate self-harm and their parents, and secondly we compared the social representations about the functions of deliberate self-harm from adolescents with a history of these behaviors and their parents' social representations. Results revealed significant differences between both groups of families, implying that the groups of participants represent the functions of deliberate self-harm differently. Overall, parents emphasized interpersonal functions and devalued intrapersonal functions. These differences were heightened in the families of adolescents with deliberate self-harm. The present article provides important insights regarding the social representations about the functions of deliberate self-harm and the differences between parents' social representations and their children experiences and social representations.
- Is suicidal intent present when adolescents engage in non-suicidal self-injury? A research notePublication . Duarte, Eva; Gomes, Hugo S.; Gouveia Pereira, M.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 NSSI. Methods Data were collected through the administration of a self-report questionnaire to 295 adolescents and young adults aged between 13 and 22 years, with a lifetime prevalence of NSSI. Results Results revealed that a large proportion of participants who reported no previous SB still report SI when engaging in NSSI. Regarding the diversity and severity of NSSI, both variables predicted the presence of SI during NSSI. Conclusion These findings demonstrate that, although NSSI does not have underlying SI, it is often present when individuals practice these behaviors.
- Testing the general theory of crime with the circumplex model: Curvilinear relations between family functioning and self-controlPublication . Gomes, Hugo S.; Pereira, Maria GouveiaThe 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 functioning and juvenile deviant behavior, contrary to self-control which presented curvilinear relations with family cohesion and flexibility (i.e. both high and low extreme levels were associated with low self-control). This finding suggests a new approach to the familial origin of low self-control.
- The validity of the Violence Risk Scale (VRS) in a Portuguese sample of remand prisonersPublication . Andrade, Joana; Gomes, Hugo S.; Abrunhosa Gonçalves, Rui; Wong, Stephen; Castro Rodrigues, Andreia deThis 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 evidence of the goodness of fit of the original two-factor model. Also, our findings indicated acceptable internal consistency for both sub scales. The correlational analyses supported both convergent and discriminant validity of the VRS. Finally, this study also tested known-groups validity. The VRS score showed a satisfactory postdictive accuracy, which means that it is able to demonstrate distinctive scores for groups known to vary on the variables being measured. We consider this work represents an essential support for decision-makers to evaluate the appropriateness of different judicial measures.
