Online, group, low-intensity psychological intervention for adults, children, and parents with food allergy

Abstract

BackgroundFood allergy (FA) impairs psychological wellbeing because of constant vigilance, planning and preparation, dietary and social restrictions, and fear of accidental ingestion, though psychological interventions are sparse. ObjectiveTo examine online, group, low-intensity psychological interventions for adults, children, young people (CYP), and parents with food allergies. MethodsThe randomized controlled trials assessed the feasibility and signal of the efficacy of a psychological intervention for adults, CYP, and parents with FA. Participants were randomized to receive the psychological intervention or treatment as usual. The intervention consisted of two, 3-hour manualized online sessions spaced 1 week apart. All participants completed relevant Food Allergy Quality of Life Questionnaires (FAQLQ) and worry (Penn State Worry Questionnaires), in addition to exploratory outcomes, at baseline, 1 month, and 3 months. ResultsA total of 129 participants (n = 44 adults, n = 52 CYP, and n = 33 parents) were recruited and randomized; 95 (74%) (n = 36 adults, n = 35 CYP, and n = 24 parents) were retained at 3 months. Owing to baseline differences, mean change was used for parent and CYP outcomes. The psychological intervention demonstrated large FAQLQ benefits across adults (g = −1.12, 95% CI −0.41 to −1.28), CYP (g = 1.23, 95% CI 0.51-1.95), and parents (g = 1.43, 95% CI 0.54-2.30) compared with controls at 3-months. ConclusionThis study provides encouraging findings regarding the feasibility of online, group, low-intensity psychological interventions, in terms of recruitment and retention as well as a signal of efficacy on FAQLQ. A definitive trial including health economic analysis and FA-specific psychological measures with consideration of best routes to implementation, is warranted.
