The present study examined relations between choice preference and reaction time to emotionally valenced words, dysphoric symptoms (BDI), and dysfunctional attitudes (DAS) in clinically depressed (CD; n= 61), previously depressed (PD; n= 42), and never depressed controls (ND; n= 46). The results showed: (1) NDs and PDs exhibited a choice preference for the relatively more positive words and differed significantly from CDs; (2) PDs and CDs exhibited longer reaction time and differed significantly from NDs; and (3) BDI and DAS were positively associated with reaction time to positively valenced words, whereas no associations were found for reaction time to negatively valenced words. The increased reaction time, in PDs and CDs, is discussed as a possible vulnerability factor to depression, which may be related to decreased approach motivation.
本研究考察了临床抑郁症患者(CD;n = 61)、既往抑郁症患者(PD;n = 42)和从未患过抑郁症的对照组(ND;n = 46)在对带有情绪色彩的词汇的选择偏好、反应时间、烦躁症状(BDI)和功能失调性态度(DAS)之间的关系。结果显示:(1)ND组和PD组对相对更积极的词汇表现出选择偏好,且与CD组有显著差异;(2)PD组和CD组的反应时间更长,且与ND组有显著差异;(3)BDI和DAS与对积极情绪词汇的反应时间呈正相关,而对消极情绪词汇的反应时间未发现相关性。PD组和CD组反应时间的增加被认为是抑郁症可能的易感性因素,这可能与趋近动机降低有关。
