Both impact of rheumatoid arthritis (RA) on valued life activities and dissatisfaction with abilities have been linked to depression among individuals with RA. We integrated these concepts by examining the hypothesis that satisfaction with one's abilities may explain the mechanism by which the impact of RA on valued activities leads to depression.
Data were collected over 2 years (1997 and 1998) through interviews with the University of California, San Francisco, RA panel. Analyses examined whether activity impairment in 1997 predicted later (1998) dissatisfaction with abilities and depression.
Greater impact on activities predicted dissatisfaction with abilities, which in turn was associated with higher depression scores. There was no direct relationship between activity impact and depression when satisfaction with abilities was considered.
Satisfaction with abilities mediated the relationship between the impact of RA on valued activities and an increase in depressive symptoms, suggesting a need to assess not only physical decline but also individuals' interpretation of the decline.
类风湿关节炎（RA）对重要生活活动的影响以及对自身能力的不满均与类风湿关节炎患者的抑郁相关。我们通过检验以下假设来整合这些概念，即对自身能力的满意度可能解释类风湿关节炎对重要活动的影响导致抑郁的机制。
通过对加利福尼亚大学旧金山分校类风湿关节炎专题小组进行访谈，在两年（1997年和1998年）期间收集数据。分析检验了1997年的活动损伤是否能预测之后（1998年）对能力的不满和抑郁情况。
对活动的更大影响预示着对能力的不满，而这反过来又与更高的抑郁评分相关。当考虑对能力的满意度时，活动影响与抑郁之间没有直接关系。
对能力的满意度介导了类风湿关节炎对重要活动的影响与抑郁症状增加之间的关系，这表明不仅需要评估身体衰退情况，还需要评估个体对衰退的理解。
