Persuasive strategies in digital interventions to combat internet addiction: A systematic review

The internet provides valuable benefits in supporting our lives. However, concerns arise regarding internet addiction, a behavioural disorder due to excessive and uncontrolled internet use that has harmful effects on human health and wellbeing. Studies highlighted the potential of digital behaviour change interventions to address health behaviour problems. However, little is known about how and to what extent persuasive strategies can be utilised in digital interventions to combat internet addiction. Accordingly, this systematic review aims to investigate the design and implementation of persuasive strategies in digital interventions to combat internet addiction, including their contexts, features, and outcomes.

We searched for peer-reviewed articles from four databases (Scopus, Web of Science, ACM, and PubMed). The Persuasive Systems Design (PSD) model and Behaviour Change Technique (BCT) taxonomy were used to identify persuasive strategies. We included 14 primary studies discussing digital interventions to address the problem and their outcomes.

Four persuasion contexts were identified, including 1) self-management systems to reduce internet use, 2) analytics systems to examine use patterns and provide behavioural suggestions, 3) parental control systems to manage children's internet use, and 4) unattractive settings to discourage internet use. The promising interventions used the following persuasion route: help the user determine behaviour goals, facilitate actions to accomplish behaviour goals, and reinforce the user to perform behaviour goals. Potential persuasive strategies were also identified, including goal-setting, action planning, task reduction, tunnelling how to perform a behaviour, tailored and personalised suggestions/prompts, reminders, trustworthiness, anticipated regret, and social support strategies.

Our findings shed light on the promising persuasive contexts and strategies to combat internet addiction using digital interventions. We suggest future research and practices to utilise our findings to develop effective digital interventions, especially for combatting internet addiction in vulnerable populations like children or people from developing regions.
