The aims of the study are to examine the predictive role of fluctuations in daily life mood, social contexts, and behavior on subsequent suicidal ideation (SI); and to identify clinical and psychological factors associated with the general frequency of SI in a high-risk sample. The sample comprised 42 adults (73.8% female) hospitalized for a suicide attempt. Immediately following hospital discharge, they used Ecological Momentary Assessment for seven consecutive days, providing repeated measures of SI, environmental, contextual, and behavioral factors. Controlling for prior SI, a number of contextual variables were associated with subsequent SI. Being at home or at work were both associated with an increased probability of SI, while being in the home of close others, or in a festive or leisure environment decreased SI probability. Working, passive leisure and inactivity all increased the likelihood of SI. Being alone increased SI while being with close others significantly reduced this risk. Finally, no overall effect for stressful events was found but negative family events specifically were associated with increased likelihood of SI (γ = 0.448, t = 2.255, df = 29, p < 0.05). The findings provide preliminary results regarding proximal environmental and behavioral factors associated with the occurrence of suicidal ideation in a high-risk sample.
本研究旨在考察日常生活情绪、社会环境和行为波动对随后自杀意念（SI）的预测作用；并确定与高危样本中 SI 一般频率相关的临床和心理因素。样本包括 42 名因自杀未遂而住院的成年人（73.8%为女性）。他们在出院后立即使用生态瞬间评估法连续 7 天，对 SI、环境、情境和行为因素进行了重复测量。在控制先前 SI 的情况下，许多情境变量与随后的 SI 相关。在家或工作时，SI 的可能性都会增加，而在亲近他人的家中，或在节日或休闲环境中，SI 的可能性则会降低。工作、被动休闲和不活动都会增加 SI 的可能性。独处会增加 SI，而与亲近的人在一起则会显著降低这种风险。最后，没有发现压力事件的总体影响，但负面家庭事件与 SI 的可能性增加有关（γ=0.448，t=2.255，df=29，p<0.05）。这些发现提供了关于高危样本中与自杀意念发生相关的近端环境和行为因素的初步结果。
