Chronic pain: a multiple-setting comparison of patient characteristics

Chronic pain patients attending four different pain management programs (N = 160) were compared on multiple variables encompassing demographics, the nature of the pain problem, and treatment history. Programs were selected because they differed on several dimensions (e.g., geographic location, general hospitals vs those serving veterans of Armed Services, university affiliated vs nonaffiliated) believed potentially to interact with treatment outcome. Results indicated differences between hospital programs serving veterans and general hospital programs (serving nonveterans) in terms of patients' age, percentage married, disability compensation, duration of pain symptoms, and treatment history. In addition, findings indicated that covariance among pain variables was dissimilar across the four types of pain programs, making it difficult to generalize from one type of setting to another regarding issues such as choice of optimal treatment.
