生态瞬时评估已被用于调查广泛的行为和精神状况。以往的研究一直取得了可喜的成果，高接受率和遵守率，只有轻微的反应性影响的特定变量。尽管这种方法对严重精神病人群的研究有希望，但对其在自杀风险样本中的可行性知之甚少。在本研究中，四个不同自杀风险的样本通过在一周内每天响应五次电子评估完成了生态瞬时评估研究。样本包括健康对照组（n=13）、情感对照组（n=21）、过去自杀未遂者（n=20）和最近自杀未遂者（n= 42）。结果表明，所有群体的参与率令人满意，对日常生活重复评估的依从性很高。重要的是，负面想法或自杀意念对研究的持续时间没有反应，这表明在日常生活中重复评估这些认知对其频率几乎没有影响。研究结果提供了支持使用生态瞬间评估的自杀意念的研究，并建议移动的技术代表了新的机会，为评估高风险的认知状态的患者在日常生活中经历的。(c)2014爱思唯尔爱尔兰有限公司版权所有。
Ecological Momentary Assessment has been used to investigate a wide range of behaviors and psychiatric conditions. Previous investigations have consistently obtained promising results with high acceptance and compliance rates, and with only minor reactive effects for specific variables. Despite the promise of this methodology for the study of severe psychiatric populations, little is known about its feasibility in samples at risk for suicide. In the present study, four samples at varying risk for suicide completed an Ecological Momentary Assessment study by responding to five electronic assessments per day over a one-week period. Samples included healthy controls (n=13), affective controls (n=21), past suicide attempters (n=20), and recent suicide attempters (n= 42). The results demonstrate satisfactory participation rates and high compliance with daily life repeated assessments across all groups. Importantly, negative thoughts or suicidal ideation were not reactive to the duration of the study, indicating that the repeated assessment of such cognitions in daily life have little or no effect on their frequency. The findings provide support for the use of Ecological Momentary Assessment in the study of suicidal ideation and suggest that mobile technologies represent new opportunities for the assessment of high-risk cognitive states experienced by patients in daily life.
