Factors Associated with Perceived Feasibility and Willingness of Non-Psychiatric Doctors in Japan to Treat Depressed Patients

Abstract

We previously reported that many non-psychiatric doctors in Japan believe that treating depression was not part of their duties. Educational interventions must address motivation of physicians to play a role in depression care. In this study, we explored factors associated with perceived feasibility and willingness of non-psychiatric doctors in Japan to treat depression. The study population included non-psychiatric doctors of the General Physician-Psychiatrist (G-P) Network group in Japan. We explored perceived feasibility and willingness to treat depressed patients, and examined preliminary associations with attitudes toward depression (the Depression Attitude Questionnaire: DAQ) and current depression treatment in routine medical practice. Responses were obtained from 56 non-psychiatric doctors (response rate: 35.4%). The doctors who scored high on the "Professional" and "Pessimism" subscale of the DAQ believed that treating depressed patients was not feasible (chi2 = 13.6, p < 0.01; chi2 = 7.3, p < 0.05, respectively) and were not willing to treat depressed patients (chi2 = 9.4, p < 0.01; chi2 = 6.6, p < 0.05, respectively) as part of their routine medical practice. The doctors who scored high on the "Professional" subscale referred fewer depressed patients to psychiatrists (r = -0.33, p < 0.05), and those who scored high on the "Pessimism" subscale recognized fewer depressed patients (r = -0.39, p < 0.01). The present study showed that attitudes toward depression were associated with perceived feasibility and willingness to treat depressed patients and with under-diagnosis of depression. Educational interventions optimized for these attitudes should be developed to improve recognition and treatment of depression in Japan.
