The present study used archival data from 333 patients with chronic pain to compare the goodness-of-fit of four covariance structure models of causes for depressive symptoms. In accordance with predictions from a cognitive-behavioural approach, all four models proposed that pain severity was mediated by avoidance behaviours and cognitions of personal mastery. Model A hypothesized unidirectional pathways between pain severity, avoidance behaviours, and personal mastery cognitions, leading to depressive symptoms. Model B was identical, except for the addition of a bidirectional pathway between avoidance behaviours and personal mastery cognitions. Models C and D were the same as Models A and B, respectively, except for the addition of the exogenous latent variable Pain Duration, which was hypothesized to influence both avoidance behaviours and personal mastery. Each model was evaluated on two independent samples of patients with chronic pain. None of the models achieved an appropriate over-all goodness of fit to the data, and none of the nested model comparisons were significant upon replication. However, a number of meaningful results were obtained. Although all models accounted for at least 73% of the variance in depression scores, the link between pain severity and depressive symptoms was repeatedly non-significant, suggesting the involvement of other factors. Furthermore, the pathways between pain severity and avoidance behaviours, and between avoidance behaviours, and depressive symptoms, were not consistently significant, indicating that targeting avoidance behaviours in chronic pain treatment programs is not necessarily effective in affecting other areas of the pain experience. In both samples, personal mastery cognitions demonstrated a significant inverse relationship with both pain severity and depression scores, suggesting that cognitions concerning self-efficacy and perceived control may be a focus for intervention. This pattern was also demonstrated in a post hoc exploration of the models, which produced one model with a marginal fit to the data that replicated over both samples. This model accounted for at least 77% of the variance in depressive symptoms scores over both samples. The analysis indicated that neither pain seventy, avoidance behaviours, personal mastery cognitions, nor depressive symptoms varied significantly with the length of time patients had been experiencing painful symptoms. These findings are examined in relation to current models of depression in patients with chronic pain.
