According to hopelessness theory, hopelessness expectancy is the proximal, sufficient cause of hopelessness depression. Consequently, hopelessness expectancy is viewed as mediating the influence of all other factors on hopelessness depression. Using a longitudinal research design, we examined hopelessness expectancy as a mediator of the relation between illness attributions and hopelessness depression in a sample of 57 adults with rheumatoid arthritis. Although hopelessness expectancy was a strong predictor of hopelessness depression, it moderated rather than mediated the relation between attributions and depression. Finding support for a moderating rather than a mediating model is inconsistent with theory but is consistent with the findings of Riskind, Rholes, Brannon, and Burdick (1987).
根据绝望理论，绝望预期是绝望抑郁的直接充分原因。因此，绝望预期被视为介导所有其他因素对绝望抑郁的影响。我们采用纵向研究设计，在57名类风湿性关节炎成年患者样本中，检验了绝望预期作为疾病归因与绝望抑郁之间关系的中介变量。尽管绝望预期是绝望抑郁的有力预测指标，但它调节而非介导了归因与抑郁之间的关系。对调节模型而非中介模型的支持与理论不符，但与里斯金德、罗尔斯、布兰农和伯迪克（1987年）的研究结果一致。
