Theoretical Perspectives of Adherence to Web-Based Interventions: a Scoping Review.

PURPOSE: The purpose of this paper is to review the literature as this relates to theoretical perspectives of adherence to web-based interventions, drawing upon empirical evidence from the fields of psychology, business, information technology and health care.

METHODS: A scoping review of the literature utilising principles outlined by Arksey and O'Malley was undertaken.

RESULTS: Several relevant theoretical perspectives have emerged, eight of which are charted and discussed in this review. These are the Internet Intervention Model, Persuasive Systems Design, the 'PERMA' framework, the Support Accountability Model, the Model of User Engagement, the Technology Acceptance Model, the Unified Theory of Acceptance and Use of IT and the Conceptual Model of User Engagement.

CONCLUSIONS: The findings of the review indicate that an interdisciplinary approach, incorporating a range of technological, environmental and individual factors, may be needed in order to comprehensively explain user adherence to web-based interventions.
