A feasibility study comparing a web-based intervention to a workshop intervention for caregivers of adults with eating disorders

Objective To assess for the validity of a future trial, the current feasibility study aimed to compare the feasibility and efficacy of a web- and workshop-based education intervention for caregivers of adults with eating disorders. Methods Psychoeducation was provided to caregivers, who were randomly assigned to a web or workshop condition. Independent samples t tests were conducted to analyse the between-group effect sizes for intervention condition with regard to change over time. A random selection of participants from each intervention provided qualitative feedback about their experiences. Results Overall, participants reported positive experiences in both education interventions. From baseline to the end of intervention, small between-group effect sizes were observed for changes in caregiver accommodation, problem-solving abilities, the quality of psychological health, and the quality of social relationships, favouring the web-based intervention, and changes in expressed emotion in the family context, caregiver burden, perceived stress, and the quality of the environment, supporting the workshop intervention. Conclusions There was a difference in initial feasibility of the web intervention. A future large-scale trial of these interventions is supported by the results of this feasibility study.
