This study investigates the screening for depressive symptoms among middle-aged and older homeless adults based on Patient Health Questionnaire-9 (PHQ-9) and examines the possible factors associated with their major depressive symptoms. A cross-sectional survey was employed, and research subjects included 129 homeless people aged 45 years old and over in Taipei Wanhua District and Taipei Main Station. We used a structured questionnaire and face-to-face interview conducted by three social workers to collect data in the analyses. The content of the questionnaire included an informed consent form, demographic characteristics, enabling and need factors of healthcare, and PHQ-9 of homeless people. Results revealed that 15.5% respondents were free of depressive symptoms, 16.3% had mild level (score 5-9), 31.8% had moderate level (score 10-14), 26.4% had moderately severe level (score 15-19), and 10.1% had severe level of depressive symptoms (score 20-27). Adopting a PHQ-9 score 10 as a cut-off point for major depressive symptoms, 68.3% of middle-aged and older homeless adults were the cases needing to be referred to healthcare settings for further recheck in the near future. A multiple regression analysis found gender, age, and usage of psychiatric outpatient care were associated with major depressive symptom occurrence. The female participants were less likely to have major depressive symptoms than the male participants (OR = 0.29, 95% CI = 0.09-0.96). The elderly participants were more likely to have major depressive symptoms than the aged 45-54 years (OR = 5.29, 95% CI = 1.44-19.41). Those participants who have ever used psychiatric outpatient care were significantly more correlated with the occurrence of major depressive symptoms than their counterparts (OR = 3.65, 95% CI = 1.46-9.09). The present study suggests that in the future health policy should eliminate the risk factors of depressive symptoms and improve mental healthcare access, to improve the health and wellbeing of the homeless population.
