Internal health locus of control as a predictor of pain reduction in multidisciplinary inpatient treatment for chronic pain: a retrospective study.

Chronic pain is a major health concern and its treatment requires physiological as well as psychological interventions. This study investigates the predictive value of health locus of control (HLOC) in pain intensity in chronic pain patients in an inpatient treatment setting. Data of 225 patients with a chronic pain condition were collected in a psychosomatic university clinic in Switzerland. Self-report assessment tools were used to measure pain intensity pre- and posttreatment and with a questionnaire dimensions of the HLOC were captured. Using hierarchic linear regression analysis, the predictive value of HLOC was investigated. A higher internal HLOC at pre-treatment was associated with a greater reduction in pain intensity from pre- to posttreatment ( Internal HLOC showed predictive value regarding the reduction in pain intensity in a multidisciplinary inpatient treatment for chronic pain, whereas social-external and fatalistic-external HLOC did not. Early interventions to strengthen internal beliefs of health control may be a promising component in multidisciplinary inpatient treatment for patients with chronic pain.
