This study investigated the role of perceived daily stress as a potential moderator in the relation between a set of predictors (disease activity, education, pain) and psychological status (anxiety, depression) of 31 patients with rheumatoid arthritis. Psychological measures served as dependent variables in hierarchical regression analyses testing for potential interaction effects of daily stress upon relationships between predictors and dependent measures. No predictors predicted directly scores on depression and anxiety; however, daily stress directly predicted scores on depression and anxiety, even after having separately controlled for each of the predictors. Increased disease activity had significantly stronger associations with increased psychological morbidity only among patients reporting high scores on daily stress, suggesting a potential moderating role for stress.
本研究调查了感知到的日常压力作为潜在调节因素，在31名类风湿性关节炎患者的一组预测因素（疾病活动度、教育程度、疼痛）与心理状态（焦虑、抑郁）之间关系中的作用。在分层回归分析中，心理测量指标作为因变量，以检验日常压力对预测因素与因变量关系的潜在交互作用。没有预测因素能直接预测抑郁和焦虑得分；然而，即使在分别控制了每个预测因素之后，日常压力仍能直接预测抑郁和焦虑得分。仅在报告日常压力高分的患者中，疾病活动度增加与心理发病率增加之间的关联显著更强，这表明压力具有潜在的调节作用。
