本研究旨在探讨强化敏感理论、生活压力与内化症状之间的关系。一般来说，行为接近系统（BAS）的低敏感性预测抑郁，而行为抑制系统（BIS）的高敏感性预测焦虑和抑郁。然而，很少有研究探讨了生活压力变量如何与生活压力相互作用来预测这些症状。据推测，较高的BIS敏感性将预测更大的焦虑唤醒;较低的BAS敏感性和较高的BIS敏感性将预测更大的快感缺乏抑郁症的联合子系统假说（JSH）预测;和低BAS，高BIS，高生活压力将相互作用，预测快感缺乏抑郁症症状，而高BIS与高生活压力将预测焦虑症状。285名大学生完成的抽样措施，生活压力，内化症状。较高的BIS敏感性预测混合型焦虑抑郁和快感缺失型抑郁症状，较低的BAS预测快感缺失型抑郁症状，生活事件预测混合型焦虑抑郁。三因素相互作用表明，对于高生活压力，BIS预测这两种类型的症状。对于低生活压力，低BAS和高BIS预测快感缺乏型抑郁，而高BIS和高BAS预测混合型焦虑抑郁。这些研究结果的影响进行了讨论的JSH。(c)2007爱思唯尔有限公司保留所有权利。
This study examined the relationship between reinforcement sensitivity theory (RST), life stress, and internalizing symptoms. Generally, low sensitivity of the behavioral approach system (BAS) predicts depression whereas high sensitivity of the behavioral inhibition system (BIS) predicts anxiety and depression. However, few studies have examined how RST variables interact with life stress to predict these symptoms. It was hypothesized that higher BIS sensitivity would predict greater anxious arousal; lower BAS sensitivity and higher BIS sensitivity would predict greater anhedonic depression as predicted by the joint subsystems hypothesis (JSH); and low BAS, high BIS, and high life stress would interact to predict anhedonic depression symptoms whereas high BIS with high life stress would predict anxious symptoms. A sample of 285 undergraduates completed measures of RST, life stress, and internalizing symptoms. Greater BIS sensitivity predicted mixed anxiety-depression and anhedonic depressed symptoms, lower BAS predicted anhedonic depression symptoms, and life events predicted mixed anxiety-depression. Three-way interactions indicated that for high life stress, BIS predicted both types of symptoms. For low life stress, low BAS and high BIS predicted anhedonic depression whereas high BIS and high BAS predicted mixed anxiety-depression. The implications of these findings are discussed in terms of the JSH. (c) 2007 Elsevier Ltd. All rights reserved.
