The present article focuses on the validation of the Questionnaire of Social Representations about the Functions of Deliberate Self-Harm for adults. The understanding of the social representations about deliberate self-harm can be relevant for clinical intervention and prevention. However, there is still a lack of instruments to assess these representations. The basis for this instrument was the translation of the Inventory of Statements About Self-Injury. To complement this instrument, we conducted semi-directive interviews with adults without deliberate self-harm and analysed the Portuguese written press. Results from these studies complemented the questionnaire with new items and functions. Study 1 consisted of an exploratory factor analysis with a sample of 462 adults. Results revealed a two-factor structure of interpersonal and intrapersonal dimensions. After item reduction, the factorial analysis of the independent functions was also acceptable. This structure was then corroborated in Study 2 by a confirmatory factor analysis with a new sample of 474 adults, revealing 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.

关于故意自残功能的社会表征：葡萄牙成年人问卷的构建和验证

本文着重于对成年人故意自残功能的社会表征问卷的验证。对故意自残的社会表征的理解可能与临床干预和预防相关。然而，仍然缺乏评估这些陈述的工具。该文书的基础是对自伤陈述清单的翻译。为了补充这个工具，我们在没有故意自残的情况下对成年人进行了半指导性的采访，并分析了葡萄牙的书面新闻。这些研究的结果用新的项目和功能补充了问卷。研究 1 包括对 462 名成年人样本的探索性因素分析。结果揭示了人际和人际维度的双因素结构。减少项目后，独立函数的因子分析也是可以接受的。这种结构随后在研究 2 中通过对 474 名成年人的新样本进行验证性因素分析得到证实，揭示了可接受的模型拟合。该问卷呈现出相对稳固的结构，并基于可接受的心理测量特性，可用于未来的研究。
