Introduction: Caregivers of patients with schizophrenia are under the burden of continuous and difficult processes. Determination of the factors related to caregiver burden in schizophrenia may help find strategies to decrease the burden. This study aimed at investigating the factors associated with caregiver burden among relatives of patients with schizophrenia.
Methods: Eighty-eight caregivers of patients under treatment for schizophrenia for at least 1 year were included in the study. The Zarit Caregiver Burden Interview was used for the assessment of caregiver burden. Sociodemographical data, the level of knowledge about schizophrenia, clinical impression scale, and global assessment of functioning were used to evaluate the related factors.
Results: Caregiver burden was negatively correlated with income level and functionality of the patient and was positively correlated with the age of the caregiver, the daily time spent with the patient, and the number of hospitalizations of the patient (p<0.05). There was no significant correlation between the caregivers' knowledge about schizophrenia and caregiver burden (p<0.05). Living in the same house with the patient was a positive predictor, whereas functionality and income level of the patient and education level of the caregiver were negative predictors (p<0.05).
Conclusion: This study highlighted the importance of setting targets for improving the functionality of patients in the design and implementation of rehabilitation and support programs for patients with schizophrenia. Additionally, providing higher income for patients, creating conditions for an independent life, and increasing incentives for younger caregivers with a higher educational level may help decrease caregiver burden.
