Increasing Retention in a Trial by Supporting Basic Psychological Needs for Autonomy, Competence and Relatedness: Developing a Theory-Informed App-Based Complex Intervention.
Ontology highlight
ABSTRACT: Aims and objectives
Most interventions to improve retention in randomised trials have low or uncertain evidence of effect and are not informed by behaviour change science even though behaviour change is their aim. Self-Determination Theory is an evidence-based theory within behaviour change science which argues that supporting basic psychological needs for autonomy, competence and relatedness leads to high-quality motivation, active engagement and well-being. The purpose of this study was to develop a need-supportive digital intervention supporting these three psychological needs to increase retention in a randomised allergy trial.Methodological design
We applied the Medical Research Council's framework for complex interventions and merged the development phase with steps suggested by O'Cathain and colleagues. Development was an iterative process involving patient partners. It included: (1) Evidence review, (2) Identification of theory, (3) Interviews, (4) Workshops, (5) Prototyping, and (6) Programme theory.Results
We developed a web app intended to support participants' basic psychological needs informed by findings from stages one to six in this development process. It included the following features: (a) the option to only complete all questions on days with symptoms, (b) the possibility to answer up to 48 h later, (c) positive feedback when responding to a questionnaire, (d) pollen counts and forecasts, (e) personal and total response rate, (f) visualisation of data entered, (g) advice about grass pollen allergy, (h) updates on the status of the allergy trial, (i) an ability to change the time of the reminder, (j) download icon and (k) contact information.Conclusions
This study provided findings on how to support basic psychological needs among participants with grass pollen allergy in a randomised trial through need-supportive technology. The web app was ready for a randomised feasibility test within the allergy trial during the grass pollen season of 2022.Trial registration
