This study compared an outpatient pain self-management (PSM) program, using cognitive-behavioural therapy and exercises, with 2 control conditions in 141 chronic pain patients aged > 65 years. Results immediately posttreatment indicated that relative to the exercise-attention control (EAC) group, the PSM group was significantly improved on measures of pain distress, disability, mood, unhelpful pain beliefs, and functional reach. The mean effect size for these gains was 0.52 (range 0.44 to 0.68). By 1-month follow-up, relative to the EAC group, the PSM group remained better on most measures. At the 1-month follow-up, relative to a waiting list (usual care) (WL) group, the PSM group was significantly improved on measures of pain distress, disability, and unhelpful pain beliefs. The mean effect size for these variables was 0.69 (range 0.56 to 0.83). Relative to the WL group, the EAC group made no significant gains on any of the measured variables. At 1-month follow-up, the mean proportion of reliably improved cases (across outcome variables) was 41% (range 16 to 60%) for the PSM group, twice that of those who met this criterion in the 2 control conditions (and this difference was statistically significant). Similarly, significantly more (44%) of the PSM group (versus 22% and 20% for the control groups) achieved a clinically significant improvement on pain disability. In the short term at least, cognitive-behavioural therapy-based PSM was more effective than exercises and usual care.
