Effectiveness of a Dyadic Pain Management Program for Community-dwelling Older Adults with Chronic Pain

Objective: To evaluate the effectiveness of a dyadic pain management program (DPM) in reducing pain and psychological health symptoms, improving pain self-efficacy, quality of life, and physical function in older adults. Hypothesis: DPM is more effective in reducing pain and psychological health symptoms, improving pain self-efficacy, quality of life, and physical function among older adults than the usual care, upon completion of the DPM (week 8) and over time (week 16). Design and subjects: Clustered randomized controlled trial with neighborhood elderly centers (NEC) as cluster; 150 dyads (one older adults and his/her caregiver as one dyad) will be recruited from 22 NEC clusters. Each NEC will be randomly allocated to experimental group (receive DPM), control group (receive usual care and pain management pamphlet). Study instruments: Brief Pain Inventory; Pain Self-Efficacy Questionnaire; Short Form Health Survey-12; Depression, anxiety \& stress; Caregiver Burden Inventory; 6-minute walk test and process evaluation. Intervention: DPM, each session includes exercise, interactive pain management education, practices on non-drug techniques and using a WhatsApp (WhatsApp Messenger) group to encourage home-based exercise and practice of non-drug methods. Outcome measures: Pain intensity, pain self-efficacy, perceived health-related quality of life and experience in participating DPM, to be collected at baseline (T0), week 8 (T1), and week 16 (T2). Data analysis: Multilevel regression and/or Generalized Estimating Equation will be used for within-group and between- group comparisons.
