Resumo(s)
With the increased awareness about deliberate self-harm, the understanding of its social representations can be important for clinical intervention and prevention. However, there is still a lack of instruments to assess the social representations of the functions of these behaviors. This research focuses on the validation of the Questionnaire of Representations of the Functions of Deliberate Self-Harm for adolescents with and without a history of these behaviors. The basis for this questionnaire was the translation and adaptation of the Inventory of Statements About Self-Injury. To access adolescents' social representations, we conducted semidirective interviews and an analysis of the Portuguese written press, which complemented the questionnaire with new items and functions. Study 1 consisted of an exploratory factor analysis with a sample of 434 adolescents. Results revealed a 2-factor structure of interpersonal and intrapersonal dimensions. After item reduction, the factorial analysis of the independent functions showed acceptable psychometric values. This structure was corroborated in Study 2 by a confirmatory factor analysis with a new sample of 405 adolescents, which revealed an acceptable model fit. This questionnaire presents a relatively solid structure and is based on acceptable psychometric properties, which allows its use in future research.
