基于積極心理學的視角,以自殺的認知模型為依據考察反芻思維與自殺意念的關系,并在此基礎上建立一個有調節的中介模型,探討絕望的中介作用以及感恩的調節作用。采取問卷法對1191名大學生進行調查,結果表明:(1)反芻思維對自殺意念有顯著正向預測作用;(2)絕望在反芻思維與自殺意念之間具有中介作用;(3)感恩對反芻思維與自殺意念的中介過程存在調節作用,相對于感恩水平較高的大學生,中介效應僅在感恩水平低的大學生中顯著。

Based on cognitive model of suicidal behavior, this study constructed a moderated mediation model to examine whether hopelessness mediated the relationship between rumination and college students’ suicidal ideation, and whether this mediating process was moderated by gratitude from the positive psychology perspective. A survey with a sample of 1191 college students was conducted to explore the mediating and moderating effects. Results were as follows: 1) Rumination significantly positively contributed to suicidal ideation; 2) Hopelessness played a mediating role in the relationship between rumination and suicidal ideation;3) Gratitude moderated the mediated path through hopelessness, such that this mediating effect was only significant for one with gratitude at the low level.
