Previous research has shown that parasuicides' view of the future is characterized by an absence of anticipation of positive experiences rather than the presence of anticipation of negative experiences. The present study aimed to replicate this finding and examine whether it would also be found in parasuicides who were not depressed.
Depressed parasuicides (N = 27), non-depressed parasuicides (N = 17) and matched controls (N = 34) were assessed on their anticipation of future positive and negative experiences using an adapted fluency paradigm, where they were given a set time to generate future positive and negative anticipated experiences.
Consistent with previous findings, parasuicides showed an overall reduced anticipation of positive experiences and no overall increased anticipation of negative experiences. However, the parasuicides did show evidence of increased negative anticipation for the immediate future. The results for depressed and non-depressed parasuicides were essentially the same.
Lack of positive anticipation in the absence of increased negative anticipation is a feature of parasuicide. Although this lack of positive anticipation can occur in depression, it appears to be an independent feature of parasuicide.
先前的研究表明,自杀未遂者对未来的看法特点是缺乏对积极经历的预期,而非存在对消极经历的预期。本研究旨在重复这一发现,并检验在未患抑郁症的自杀未遂者中是否也会发现这一情况。
使用一种改编的流畅性范式,对抑郁的自杀未遂者(N = 27)、未抑郁的自杀未遂者(N = 17)和匹配的对照组(N = 34)对未来积极和消极经历的预期进行评估,在给定的固定时间内让他们生成未来积极和消极的预期经历。
与先前的研究结果一致,自杀未遂者总体上对积极经历的预期降低,对消极经历的预期并未总体增加。然而,自杀未遂者确实表现出对近期未来消极预期增加的证据。抑郁的和未抑郁的自杀未遂者的结果基本相同。
在消极预期未增加的情况下缺乏积极预期是自杀未遂的一个特征。尽管这种缺乏积极预期的情况可能发生在抑郁症中,但它似乎是自杀未遂的一个独立特征。
