- 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.
- 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.
