Predictors of attrition and exploration of the user experience of adolescents with type 1 diabetes and their parents during the randomised controlled trial of the Nothing Ventured Nothing Gained intervention

This research provides the first known comprehensive exploration of pre-treatment attrition from the randomised controlled trial of an online program for adolescents and their parents. The findings reflect the multiple complex factors that influence participant dropout which is a key consideration in the development and implementation of internet therapy. Several key predictors of attrition were identified including parent and adolescent self-efficacy, parent education levels and adolescent locus of control and reward responsiveness. The research also demonstrated the importance of exploring participant dropout in research trials, and the need for more rigorous standards regarding the reporting of attrition.
