Depression and generalized anxiety, separately and as comorbid states, continue to represent a significant public health challenge. Current cognitive-behavioral treatments are clearly beneficial but there remains a need for continued development of complementary interventions. This manuscript presents two proof-of-concept studies, in analog samples, of "microinterventions" derived from regulatory focus and regulatory fit theories and targeting dysphoric and anxious symptoms. In Study 1, participants with varying levels of dysphoric and/or anxious mood were exposed to a brief intervention either to increase or to reduce engagement in personal goal pursuit, under the hypothesis that dysphoria indicates under-engagement of the promotion system whereas anxiety indicates over-engagement of the prevention system. In Study 2, participants with varying levels of dysphoric and/or anxious mood received brief training in counterfactual thinking, under the hypothesis that inducing individuals in a state of promotion failure to generate subtractive counterfactuals for past failures (a non-fit) will lessen their dejection/depression-related symptoms, whereas inducing individuals in a state of prevention failure to generate additive counterfactuals for past failures (a non-fit) will lessen their agitation/anxiety-related symptoms. In both studies, we observed discriminant patterns of reduction in distress consistent with the hypothesized links between dysfunctional states of the two motivational systems and dysphoric versus anxious symptoms.
抑郁症和广泛性焦虑症,无论是单独出现还是作为共病状态,仍然是重大的公共卫生挑战。当前的认知行为疗法显然有益,但仍需要继续开发补充性干预措施。本手稿介绍了两项概念验证研究,研究对象为模拟样本,干预措施为源自调节焦点和调节适配理论的“微干预”,目标是缓解烦躁和焦虑症状。在研究1中,让具有不同程度烦躁和/或焦虑情绪的参与者接受简短干预,以增加或减少其对个人目标追求的投入,假设是烦躁表明促进系统投入不足,而焦虑表明预防系统投入过度。在研究2中,让具有不同程度烦躁和/或焦虑情绪的参与者接受反事实思维的简短训练,假设是促使处于促进失败状态的个体为过去的失败生成减法反事实(不匹配)将减轻其沮丧/抑郁相关症状,而促使处于预防失败状态的个体为过去的失败生成加法反事实(不匹配)将减轻其激动/焦虑相关症状。在两项研究中,我们都观察到了与两个动机系统功能失调状态和烦躁与焦虑症状之间的假设联系一致的痛苦减轻的判别模式。
