Abstract:Background: Many serious illnesses and risk factors are related to unhealthy behavior, which many people want to change. eHealth seems to be a promising means to support health behavior change. But the effects of eHealth interventions vary a lot, which is eventually explained by the way persuasive technology is applied to them. Recent research points out a significant relation between persuasive technology and adherence to web-based interventions. Unfortunately, little is known about the relationship between persuasive technology and the effects of web-based lifestyle interventions. Objective: This study’s objective is to gain more insight into the relationships between persuasive technology, the usage, and the effects of web-based lifestyle interventions. Method: By the means of a systematic literature review different studies were analyzed. According to specific coding rules the 16 included articles were coded. The relationships between persuasive technology, the effects and adherence were analyzed using Kruskal-Wallis tests. Furthermore, the possible influences of different sorts of outcome measures were investigated. Results: No significant relation between persuasive technology and the effects of web-based lifestyle interventions was found. The relationship between adherence and the intervention effects was ambiguous. In interventions with a strong effect, adherence was significant higher than in interventions with small effects. But there was no significant difference in adherence between interventions with a strong effect and interventions with no effect. Moreover, non-validated measures found systematically more positive effects compared to validated ones. Conclusion: This study could not reveal that the application of persuasive technology within web-based lifestyle interventions influences the effects of those interventions. Intervention designers should always have the goal in mind when implementing persuasive technology features. In future, researchers should explicitly describe the reasons for applying specific technology features and their implementation. Furthermore, more validated measures should be used in effect studies and the validation should be mentioned so that the quality of the measures can be compared.
