Effects of pain controllability and discrepancy in social support on depressed mood among patients with chronic pain.

Background: Preference of types of social support may vary across recipients, and social support that is less than the amount preferred may be associated with depressed mood.

Purpose: This study aimed to investigate the interaction effects between pain controllability and discrepancy in social support and the additive utility of discrepancy in social support over perceived social support in predicting depressed mood among patients with chronic pain.

Method: A total of 173 patients seeking treatment at two outpatient pain management clinics in Hawaii participated.
