PREDICTING OUTCOME OF CHRONIC PAIN TREATMENT VIA A MODIFIED SELF-EFFICACY SCALE

This study utilized a modified self-efficacy scale and examined the relationship of perceived self-efficacy to treatment outcome in a chronic, intractable, benign pain population (N = 62). In two separate studies a self-efficacy scale was given to inpatients in a combined cognitive-behavioral and medical treatment program. The scale categories consisted of (1) walking distance, (2) lifting ability, (3) pain coping, (4) working ability, and (5) social and recreational engagement. Self-efficacy beliefs were found to be associated with the level of functioning of these patients and their response to treatment. Patients with higher self-efficacy scores following treatment rated themsleves as more improved and demonstrated better overall functioning with greater reductions in chronic illness behavior at followup. These observations support the merits of self-efficacy measures as predictors of treatment outcome in chronic pain patients. © 1990.
