Key Components in eHealth Interventions Combining Self-Tracking and Persuasive eCoaching to Promote a Healthier Lifestyle: A Scoping Review

Abstract

BackgroundThe combination of self-tracking and persuasive eCoaching in automated interventions is a new and promising approach for healthy lifestyle management.ObjectiveThe aim of this study was to identify key components of self-tracking and persuasive eCoaching in automated healthy lifestyle interventions that contribute to their effectiveness on health outcomes, usability, and adherence. A secondary aim was to identify the way in which these key components should be designed to contribute to improved health outcomes, usability, and adherence.MethodsThe scoping review methodology proposed by Arskey and O’Malley was applied. Scopus, EMBASE, PsycINFO, and PubMed were searched for publications dated from January 1, 2013 to January 31, 2016 that included (1) self-tracking, (2) persuasive eCoaching, and (3) healthy lifestyle intervention.ResultsThe search resulted in 32 publications, 17 of which provided results regarding the effect on health outcomes, 27 of which provided results regarding usability, and 13 of which provided results regarding adherence. Among the 32 publications, 27 described an intervention. The most commonly applied persuasive eCoaching components in the described interventions were personalization (n=24), suggestion (n=19), goal-setting (n=17), simulation (n=17), and reminders (n=15). As for self-tracking components, most interventions utilized an accelerometer to measure steps (n=11). Furthermore, the medium through which the user could access the intervention was usually a mobile phone (n=10). The following key components and their specific design seem to influence both health outcomes and usability in a positive way: reduction by setting short-term goals to eventually reach long-term goals, personalization of goals, praise messages, reminders to input self-tracking data into the technology, use of validity-tested devices, integration of self-tracking and persuasive eCoaching, and provision of face-to-face instructions during implementation. In addition, health outcomes or usability were not negatively affected when more effort was requested from participants to input data into the technology. The data extracted from the included publications provided limited ability to identify key components for adherence. However, one key component was identified for both usability and adherence, namely the provision of personalized content.ConclusionsThis scoping review provides a first overview of the key components in automated healthy lifestyle interventions combining self-tracking and persuasive eCoaching that can be utilized during the development of such interventions. Future studies should focus on the identification of key components for effects on adherence, as adherence is a prerequisite for an intervention to be effective.

Persuasive technology and behaviour change in parent-focused eHealth interventions supporting child health: A scoping review protocol

“…The persuasive system design (PSD) model (Oinas-Kukkonen & Harjumaa, 2008), based on the original work by Fogg (2003), is a systematic way of designing and assessing persuasive technology. A growing number of studies are using this model in eHealth interventions to assess how persuasive technologies are being used and understand how they influence health outcomes more consistently (Kelders, Kok, Ossebaard, & van Gemert-Pijnen, 2012;Kelders et al, 2016;Lentferink et al, 2017;van Gemert-Pijnen et al, 2011;Wildeboer, Kelders, & van Gemert-Pijnen, 2016). The PSD model is specifically concerned with human-computer interaction, which refers to the inherent features of technology to influence the user's behaviour, rather than the features of technology which facilitate human-tohuman interaction.…”

“…The PSD model was recently expanded to include additional coaching elements that can be delivered via technology, namely goal setting, educational coaching, feedback and social support. To reflect these additions, "persuasive eCoaching" was suggested as a new term to represent the additional elements (Lentferink et al, 2017). The term "persuasive eCoaching" will be used in describing the findings of the scoping review to reflect the 28 PSD elements and the additional four coaching elements.…”

“…We will limit our search to articles published after 2008, the year that both BCTTv1 and the PSD model were first published (Michie et al, 2008;Oinas-Kukkonen & Harjumaa, 2008). The benefits of including earlier digital interventions that would not have had access to today's prevailing technologies are unlikely to add additional value to our objective of informing a future eHealth intervention (Hall & Bierman, 2015;Jones, 2014;Lentferink et al, 2017).…”

Design and Analysis Considerations for a Sequentially Randomized HIV Prevention Trial

“…The TechStep study is an ongoing randomized controlled trial (RCT) of mHealth interventions in highrisk HIV-negative trans youths and young adults (15-24 years old). Three trans-specific mHealth interventions were developed for TechStep: a short messaging service (SMS or text), a mobile-optimized webapp, and an eCoaching intervention, which offers one-on-one risk behavior counseling administered through a mobile video conferencing service [12,30]. The goal of the trial is to evaluate the efficacy of these interventions for reducing sexual risk behaviors (e.g., condomless anal or vaginal intercourse, engagement in sex work, sex while feeling the effects of alcohol or drugs) and increasing uptake of pre-exposure prophylaxis (PrEP).…”

Fuzzy modeling to 'understand' personal preferences of mHealth users: a case study

“…Hence, the challenge is to design mHealth tools that are on the long term sufficiently engaging. Tailoring an intervention to the exact needs and preferences of a user (i.e., personalization) may yield higher engagement [10], because -whenever one's preferences and needs are captured -effort can be directed efficiently to cater to these desires.…”
