Caregiver strain and symptoms of depression among principal caregivers of patients with schizophrenia and bipolar affective disorder in Sri Lanka

Introduction Data on caregiver strain and depression of principal caregivers of patients with mental illnesses are few in developing countries. Findings from developed countries cannot be applied directly to developing countries as culture specific factors may influence the outcome. Methods A prospective study was carried out in the University Psychiatry Unit of the National Hospital of Sri Lanka (NHSL) to identify symptoms of depression, caregiver strain and dissatisfaction with life in caregivers of patients with schizophrenia and bipolar affective disorder. Participants were assessed using the Center for Epidemiological Studies – Depression Scale, Satisfaction with Life Scale and the Modified Caregiver Strain Index. Results and discussion Eighty caregivers were interviewed (males; 36, 45%). Symptoms of depression were significant in 37.5%, while 48.8% had unsatisfactory scores on the Satisfaction with Life Scale. Depression and higher caregiver strain were associated with spending more time with the patient, interruption to work, disputes with relations, being assaulted by patient and self admission of needing professional help to overcome mental stress. Conclusion This study identified several associations for depression and increased caregiver strain among caregivers in a subset of patients with mental disorder in Sri Lanka. These can be used as markers to screen and increase pretest probability to identify caregivers needing help rather than applying the cumbersome questionnaires to all.
