Developing a web-based add-on intervention for parents of adolescents with anorexia nervosa: a mixed methods preliminary study

Abstract Background The aim of this study was to carry out a mixed method evaluation of the acceptability and feasibility of a web-based psycho-educational intervention for parents. Method After developing the intervention, we recruited (N = 19) families of adolescents with AN engaged in family-based therapy at an outpatient specialist center for eating disorders. Participants were given 6-month access to the intervention. Acceptability, feasibility, parental well-being and mental health, and family functioning pre and post-intervention were collected. Results Amongst families who participated and accessed the intervention (N = 11), the majority rated the intervention as satisfying (median = 6, IQR = 5–7), and easy to use (median = 7, IQR = 6.5–8.3). Frequency of use was about once a month. No significant differences between baseline and follow-up were found for parental well-being and mental health. We identified a trend for an increase in parental self-efficacy with a large effect size (p = .074, rs = -0.52). Parents identified positive aspects of the intervention as ease of access, comprehensive content and a positive impact on their approach to their child’s illness. Conclusions This study suggests that an add-on digital intervention to family-based treatment for parents of adolescents with AN is acceptable and feasible. Satisfaction, ease of navigation, and finding answers to questions were positively rated. Web-based or computerized psychoeducation for parents can be a valuable addition to treatment for adolescent AN.
