Burden and satisfaction with social support in families with a history of problematic substance use or dementia - a comparison

Background Living in a family with a history of problematic substance use or dementia is a major stressful experience for family members and results often in an impaired health condition. Seeking and receiving social support has been emphasized as a major resource while coping with this stress. However, especially family members of people with problematic substance use often refrain from help-seeking. This paper examines whether (1) family members of problematic substance users are more physically and psychologically distressed than caregivers of people with dementia, and (2) whether and to what extent differences are mediated by satisfaction with perceived professional and private social support. Methods Two samples of family members of people with a chronic disease (problematic substance use (n = 221), dementia (n = 322)) completed self-administered questionnaires on burden, quality of life and social support. Physical distress was assessed using the Giessen Subjective Complaints List, psychological distress using the Center for Epidemiological Studies Depression Scale and anxiety symptoms using the Hospital Anxiety and Depression Scale. Quality of life was measured using the WHOQOL-BREF, and satisfaction with professional and private social support was assessed using a visual analog scale. Multivariate analyses of variance were performed to compare the two groups on the means of (1) burden ratings and (2) QoL dimensions and followed up by discriminant analyses to explore meaningful variables according to group differences. Parallel mediation analyses were performed to test the mediators private and professional support. Results Family members of problematic substance users score higher on the burden indicators, while they score lower with regard to the quality of life dimensions than caregivers of people with dementia. The difference in burden is mainly explained by the higher scores for exhaustion, stomach discomfort and depression of family members of problematic substance users. Caregivers of people with dementia reported greater satisfaction with perceived social support, either private or professional. Satisfaction with private support was shown to be more important in mediating the impact of stress. Conclusions Family members of people with problematic substance use are in great need of tailored support programs and should be explicitly targeted.
