The main goal of the present study was to identify and validate latent classes of suicidal behavior in a representative sample of adolescents. The sample comprised a total of 1506 students, including 667 males (44.3%), selected through a sample stratified by clusters. The mean age was 16.15 years (SD 1.36). The instruments used evaluated suicidal behavior, positive and negative affect, emotional and behavioral problems, prosocial behavior, and subjective well-being. Using the Paykel Suicide Scale, the latent class analysis identified four homogeneous subgroups: "low risk", "suicidal act", "suicidal ideation", and "high risk for suicide". These subgroups presented a differential pattern in terms of their social-emotional adjustment. The subgroups with the highest theoretical risk showed lower scores on subjective well-being and positive affect as well as higher scores on emotional and behavioral problems and negative affect compared to the non-risk subgroups. This study contributes to an understanding of the typologies of suicidal behavior among adolescents and the relationship with psychopathological adjustment. Ultimately, these findings may promote the development or improvement of early detection and prevention strategies in the suicidal behavior field in order to reduce the socio-economic burdens associated with suicide in young populations.
本研究的主要目的是在代表性青少年样本中识别和验证自杀行为的潜在类别。该样本共包括 1506 名学生，其中 667 名男性（44.3%）通过按聚类分层的样本选择。平均年龄为 16.15 岁（标准差 1.36）。使用的工具评估了自杀行为、积极和消极情绪、情绪和行为问题、亲社会行为和主观幸福感。使用佩克尔自杀量表，潜在类别分析确定了四个同质亚组：“低风险”、“自杀行为”、“自杀意念”和“自杀高风险”。这些亚组在其社会情感调整方面表现出不同的模式。理论风险最高的亚组在主观幸福感和积极情绪方面的得分较低，在情绪和行为问题以及消极情绪方面的得分较高，与非风险亚组相比。这项研究有助于理解青少年自杀行为的类型学及其与心理病理调整的关系。最终，这些发现可能会促进自杀行为领域早期发现和预防策略的制定或改进，以减少与年轻人自杀相关的社会经济负担。
