AIMS: Objectives. This study examined the differential associations of patient satisfaction, and pain-specific psychosocial factors with three pain adjustment outcomes in a sample of Chinese patients with chronic pain. METHODS: Methods: A total of 178 patients with chronic pain were assessed at baseline, 3-, and 6-month following baseline using standardized questionnaire which comprised of the following measures: the Chronic Pain Grade (CPG), the Participant Compliance Reporting Scale (PCRS), the Pain Treatment Satisfaction Scale (PTSS), the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D), the Pain Catastrophizing Scale (PCS), and the Tampa Scale for Kinesiophobia (TSK) respectively. Linear mixed effects models (LME) were fitted to assess associations between variables and to identify predictors of adjustment outcomes. RESULTS: Results: After adjusting for sociodemographic and pain factors, results LME analyses showed that pain-related fear (std b = 0.10, p<0.05), activity engagement (std b = -0.46, p<0.001), and satisfaction with medical care (std b = 0.13, p<0.001) were significantly associated with depression (Model 1). Higher activity engagement and higher dissatisfaction with current pain medication were associated with higher pain disability (Model 2). Five significant predictors emerged for pain intensity (Model 3) after controlling for sociodemographic and pain factors: pain-related fear (std b = 0.13, p<0.01), activity engagement (std b = -0.15, p<0.01), satisfaction with impact of current pain medication (std b = 0.15, p<0.001), satisfaction with side effects of medication (std b = 0.10, p<0.05), and satisfaction with efficacy (std b = 0.12, p<0.05). CONCLUSIONS: Conclusions: Our data suggest there may be interaction between psychosocial factors and pain treatment satisfaction in impacting adjustment outcomes among Chinese patients with chronic pain.
