Determinants of family functioning in caregivers of persons with obsessive-compulsive disorder

Abstract

BackgroundObsessive-compulsive disorder (OCD) is known to cause significant burden to patients and their caregivers. However, there is limited data on its impact on family functioning, especially from families with an adult member having OCD. MethodsFour hundred subjects, which included treatment-seeking adult OCD patients (n = 200) and their caregivers (n = 200) were recruited. Patients were evaluated using the Mini International Neuropsychiatric Interview (MINI) and the Yale-Brown Obsessive-Compulsive Scale (YBOCS). Caregivers were evaluated using the MINI, the Caregiver Strain Index (CSI), the Hamilton Anxiety Rating Scale (HAM-A), the Hamilton Depression Rating Scale (HAM-D), the Socio-Occupational Functioning Assessment Scale (SOFAS), the Family Accommodation Scale (FAS) and the Connor-David Resilience scale (CD-RISC) in a cross-sectional interview. Family functioning was measured using the OCD Family Functioning (OFF) Scale. Structural equation modeling (SEM) was carried out to evaluate the relationships between the patient and caregiver variables to predict family functioning. ResultsFrom the best-fitting path model, we ascertained that OCD symptoms did not have a direct relationship with family dysfunction. Their effects were in turn was mediated by family accommodation, anxiety, caregiver stress/burden and depression. “Contamination & washing” was the only significant symptom dimension within the model. Caregiver resilience was found to predict only their individual functioning, and not family functioning. LimitationsStudy sample included patients from a tertiary care OCD service, only one caregiver from each patient's family was interviewed. ConclusionsEvaluating family functioning, addressing it as part of interventional modules for patients and caregivers may help improving treatment outcomes.
