This study used ecological momentary assessment (EMA) to explore the correlates of suicidal ideation (SI) instability in patients hospitalized for depression and SI. Thirty-nine adult inpatients were given smartphones with visual analogue scales to rate current depressed mood, anger/irritability, feeling socially connected, and SI three times a day throughout hospitalization. Affective Lability Scales (ALS) were also completed at baseline. SI instability was correlated with SI intensity, depressed mood instability, and social connection instability. Social connection instability was not associated with SI instability after controlling for depressed mood instability. ALS scores were not associated with EMA-derived SI instability. Participants with multiple past suicide attempts experienced greater SI instability. More research examining the clinical significance of SI instability is warranted.
本研究采用生态瞬时评估（EMA）来探究因抑郁和自杀意念（SI）住院患者中自杀意念不稳定性的相关因素。39名成年住院患者在住院期间每天三次使用视觉模拟量表对当前的抑郁情绪、愤怒/易怒、社交联系感和自杀意念进行评分，同时还配备了智能手机。在基线时还完成了情感不稳定性量表（ALS）。自杀意念不稳定性与自杀意念强度、抑郁情绪不稳定性和社交联系不稳定性相关。在控制了抑郁情绪不稳定性后，社交联系不稳定性与自杀意念不稳定性无关。ALS评分与EMA得出的自杀意念不稳定性无关。有多次既往自杀未遂经历的参与者经历了更大的自杀意念不稳定性。有必要进行更多研究来检验自杀意念不稳定性的临床意义。
