Psychosocial condition of family caregivers of patients with chronic obstructive pulmonary disease in Hong Kong.

OBJECTIVES. Chronic obstructive pulmonary disease is associated with physical and psychological burdens. Although there is research about health-related quality of life (HRQOL) of such patients, less is known about the psychosocial condition of their family caregivers. The objectives of this study were to examine the HRQOL and the burden of chronic obstructive pulmonary disease patient caregivers, and to identify associated relevant factors. METHODS. A total of 81 eligible caregivers completed a caregiver survey on HRQOL (Short Form-36 Questionnaire), caregiving burden (Cumulative Illness Rating Scale, CIRS) and other biopsychosocial factors. Descriptive statistics, correlations, and multiple linear regression models were used to analyse data. RESULTS. The caregiver's Mental Component Summary measure of the Short Form-36 was associated with each caregiver's total CIRS scores, the anxiety subscale of the Hospital Anxiety and Depression Scale, and the Lubben Social Network Scale. The caregiver's Physical Component Summary measure was associated with the patient's disability allowance, the caregiver's total CIRS score, and the Barthel Index score. Caregivers' Caregiving Burden Scale scores were associated with their Geriatric Depression Scale total score and the need to take care of other family members. CONCLUSIONS. This study demonstrates that depressive and anxiety symptoms are associated with caregivers' burden and HRQOL. Further studies on evaluating interventions on caregivers' HRQOL and burden should take mood symptoms into consideration.
