In addition, they completed a range of health status measures at baseline and three months after end of participation in the CPSMP. Health care expenditure was obtained from Danish health registers. We performed cluster analyses to identify possible subgroups based on the participants' perceptions of their chronic pain condition.RESULTS: Cluster analysis of illness perceptions resulted in three meaningful clusters, classified as "distressed, certain cause", "distressed, uncertain cause", and "non-distressed, certain cause", respectively. The two distressed groups had significantly higher scores on pain catastrophizing, illness worry, and emotional distress than did the non-distressed. Moderator analyses showed, that the "distressed, certain cause" had significant positive effect of participating in the CPSMP on pain catastrophizing and emotional distress, whereas the "distressed, uncertain cause" had a decrease and the "non-distressed, certain cause" an increase in primary health expenditure.DISCUSSION: Clusters based on IPs meaningfully distinguished chronic pain sufferers on health measures and outcome of participating in the CPSMP, and may prove useful in future studies to understand responses to treatment.
