背景先前的研究表明，准自杀者对未来的看法的特点是缺乏对积极经验的预期，而不是对消极经验的预期。本研究的目的是复制这一发现，并检查它是否也会被发现在parasuicides谁没有抑郁。采用适应性流畅性范式对抑郁性自杀者（N = 27）、非抑郁性自杀者（N = 17）和对照组（N = 34）进行了对未来积极和消极经验的预期评估，在该范式中，他们被给予一定的时间来产生未来积极和消极的预期经验。自杀未遂者对积极体验的预期总体上减少，对消极体验的预期总体上没有增加。然而，准自杀事件确实表明，人们对不久的将来的负面预期有所增加。抑郁和非抑郁的准自杀者的结果基本相同。在没有增加消极预期的情况下缺乏积极预期是准自杀的一个特征。虽然这种缺乏积极预期的情况可能发生在抑郁症中，但它似乎是准自杀的一个独立特征。
Background. 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.Method. 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.Results, 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.Conclusion. 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.
