Objective Multidrug‐resistant tuberculosis ( MDR ‐ TB ) has been a major threat for successful TB control. We examined the relationship between social support and treatment outcomes in MDR ‐ TB patients and evaluated barriers to social support. Methods Retrospective cohort study with MDR ‐ TB patients enrolled in the Global Fund programme between 1 January 2009 and 30 June 2014 in Zhejiang, China. We reviewed all MDR ‐ TB patients’ diagnoses and treatment outcomes. In‐depth interviews were conducted with 10 community health workers and 10 patients. Pathway analysis was employed to examine the association between social support and treatment outcomes, and the mediating effect of medication adherence on their relationship. Results Of 218 participants, 144 (66%) were successfully treated and 59 (27%) had poor treatment adherence. Directly observed therapy ( DOT ) had an indirect positive effect on treatment success, mediating through medication adherence ( β = 0.541, P = 0.008; β = 0.538, P < 0.001). Financial support had both a direct ( β = 0.769, P < 0.001) and an indirect positive effect on treatment success, which was mediated by a self‐reported social support scale ( β = 0.541, P = 0.008; β = 0.538, P < 0.001). The interviews indicated poor performance of DOT . Patients often suffered from substantial stigma, but were not provided with psychological support. Conclusion DOT and financial support were effective strategies for improving successful treatment outcomes in MDR ‐ TB patients, but they were delivered not considering patients’ perspectives. There is an urgent need for consistent and specific psychological support for MDR ‐ TB patients in their communities.
