Summary Background Attrition and treatment adherence are notorious challenges in paediatric obesity interventions. Objective To evaluate if brief, pretreatment motivational interviewing (MI) can improve retention (at baseline, post‐assessment and follow‐up assessment) and adherence (i.e. attendance) in a parent‐exclusive paediatric obesity intervention. Methods MI was implemented with parents as an adjunct to a larger randomized controlled trial of Nourishing Our Understanding of Role‐modeling to Improve Support and Health (NOURISH + ), a parent intervention for children with overweight ages 5–11 years. Parents ( N = 112) were randomized to receive two MI sessions (one telephone and one in person) or reminder calls. Results Parents (91% women; 52% African American) who completed one telephone MI session were more likely to attend baseline (74%) compared with parents who received reminder calls only (53%, p < .001). After a second MI session, there were no group differences in treatment initiation ( p > .05). Treatment attendance, post or 4‐month follow‐up assessment completion did not differ between conditions ( p > .05). Conclusion One MI session implemented prior to treatment can improve baseline attendance; a second MI session did not enhance these effects. A single‐session telephone‐based MI pretreatment might be a cost and time‐effective strategy to enhance recruitment efforts. Further strategies to address retention and treatment attendance are needed.
