行为理论认为，某些环境变化和回避行为抑制个体体验环境奖励和强化，从而导致抑郁症状的发展和维持。本研究以环境奖励的自我报告和行为（日常日记）指标作为正强化的替代测量，考察环境奖励是否在回避和抑郁之间起中介作用。在控制焦虑的情况下，两项环境奖励指标均显著调节抑郁与认知、行为和完全回避的关系。进行事后调解分析以检查潜在的性别差异。自我报告的环境奖励在逃避和抑郁之间的关系中起着显著的中介作用。然而，在女性中，每日日记测量的奖励仅介导认知回避和抑郁之间的关系。在男性中，每日日记奖励是所有三种形式的回避和抑郁的中介。本研究初步支持了强化作为回避和抑郁之间的重要中介，并进一步强调了回避和强化在抑郁行为概念化中的相关性。(C) 2010 Elsevier Ltd.版权所有。
Behavioral theory posits that certain environmental changes and avoidant behaviors inhibit individuals from experiencing environmental reward and reinforcement and subsequently leads to the development and maintenance of depressive symptoms. Using self-report and behavioral (daily diary) indices of environmental reward as proxy measures for positive reinforcement, this investigation examined whether environmental reward mediated the relationship between avoidance and depression. When controlling for anxiety, both indices of environmental reward significantly mediated the relationships of depression with cognitive, behavioral and total avoidance. Post-hoc mediation analyses were conducted to examine potential gender differences. Self-reported environmental reward significantly mediated the relationship between avoidance and depression across both genders. Among females, however, daily diary-measured reward only mediated the relation between cognitive avoidance and depression. In males daily diary reward was a mediator with all three forms of avoidance and depression. This investigation provides initial support for reinforcement as a significant mediator between avoidance and depression and further highlights the relevance of avoidance and reinforcement in behavioral conceptualizations of depression.
