Suicide, as one of the leading causes of death for the adolescent population, both in Chile and globally, remains a complex and elusive phenomenon. This research studies the association between positive and negative affect in relation with suicidal ideation and suicidal attempt, given that affectivity is a fundamental basis on which people make evaluations on their satisfaction with life. First, it examines the reliability, structure, and validity of Watson's positive and negative affect scale (PANAS) scale in a representative random sample of Chilean high school students ( = 4,568). The scale evidences strong reliability coefficients and a confirmatory factor analysis, excluding one positive (excited) and one negative (nervous) item. The scale shows a satisfactory goodness of fit. Secondly, it investigates the association of PANAS positive and negative affect scores with suicidal ideation as well as reported attempt in adolescents, controlling for the potential effect of age and sex ( = 420 high school students). Low positive and high negative affect, but not sex and age, show a significant association with suicidal ideation. Suicidal ideation totally mediates the association of affect with suicide attempt, as expected. Results are discussed regarding prevention and it considers how positive and negative affect can be relevant as indicators for prevention and treatment using widely available technology.
自杀作为智利乃至全球青少年主要死因之一，仍然是一个复杂且难以捉摸的现象。鉴于情感是人们对生活满意度进行评估的基本依据，本研究探讨了积极情感和消极情感与自杀意念及自杀未遂之间的关联。首先，在一个具有代表性的智利高中生随机样本（n = 4568）中，检验了沃森正负情感量表（PANAS）的信度、结构和效度。该量表显示出很强的信度系数，通过验证性因素分析，排除了一个积极项目（兴奋）和一个消极项目（紧张）。量表显示出令人满意的拟合优度。其次，在控制年龄和性别的潜在影响后（n = 420名高中生），研究了PANAS正负情感得分与青少年自杀意念及报告的自杀未遂之间的关联。低积极情感和高消极情感，而非性别和年龄，与自杀意念存在显著关联。正如预期的那样，自杀意念完全介导了情感与自杀未遂之间的关联。讨论了有关预防的结果，并考虑了如何将正负情感作为使用广泛可用技术进行预防和治疗的指标。
