Productivity loss of caregivers of schizophrenia patients: a cross-sectional survey in Japan

Abstract

Background: When a family member is diagnosed with schizophrenia, it causes stress to the caregiver that can eventually result in missed work days and lower work performance. Aim: This study aims at revealing productivity costs for caregivers of schizophrenia patients in Japan. Method: A cross-sectional survey of caregivers was conducted and resulted in 171 respondents. The assessment of work productivity included calculating the costs of absenteeism, presenteeism and total productivity costs. This was accomplished using the “Work Productivity and Activity Impairment Questionnaire” (WPAI). Results: A relative majority of caregivers in the sample provided care for their spouse (47%), 18% cared for their brother or sister and 16% provided care for their child. Per capita productivity costs totaled JPY 2.42 million, with JPY 2.36 million (97%) of that amount being due to presenteeism. Conclusions: The burden on caregivers is substantial enough to warrant structured support programs aimed at maintaining careers’ physical and mental health, helping them provide more effective care to schizophrenia patients and eventually increase productivity at work.
