Prevalence of Depression and Its Associated Factors among Caregivers of Elderly Psychiatric Patients
Objectives : To find the prevalence of depression and its associated factors among
caregivers of elderly psychiatric patients, and to evaluate burden, social support and
quality of life of caregivers.
Methods : Subjects were 181 primary caregivers of elderly patients who treated at
psychiatric outpatient clinic in Siriraj hospital. Instruments were Zarit Burden Interview,
Personal Resource Questionnaire : PRQ 85 - Part 2, SF-36 questionnaire, Mini
international neuropsychiatric interview (M.I.N.I) and Hamilton Rating Scale for
Depression (HRSD). Data were analyzed using chi-square, t-test and multiple logistic
Results : Nine of 181 primary caregivers of elderly psychiatric patients had depression;
prevalence = 5%. Most of caregivers had less than major depression (N=6, 67%).
Factors that had statistically significant correlation with depression in caregivers were
female gender (p = 0.03) and low to moderate level of self-efficacy for patient
management (p = 0.015). This study also found that group of caregivers who had
depression had more burden (p = 0.03), less social support (p = 0.002) and lower
quality of life in all aspect (p <0.001), with statistically significance. Multiple logistic
regression analysis found that lower quality of life had statistically significant correlation
with depression in caregivers (p = 0.002, OR 0.889, 95% CI 0.825 - 0.958)
Conclusion : Prevalence of depression in primary caregivers of elderly psychiatric
patients in this study was 5%, and associated factors were female gender and low to
moderate level of self-efficacy for patient management. Caregivers who had depression
had more burden, less social support and lower quality of life.
