ABSTRACT Computer-tailored interventions have become increasingly common for facilitating improvement in behaviors related to chronic disease and health promotion. A sufficient number of outcome studies from these interventions are now available to facilitate the quantitative analysis of effect sizes, permitting moderator analyses that were not possible with previous systematic reviews.
The present study employs meta-analytic techniques to assess the mean effect for 88 computer-tailored interventions published between 1988 and 2009 focusing on four health behaviors: smoking cessation, physical activity, eating a healthy diet, and receiving regular mammography screening. Effect sizes were calculated using Hedges g. Study, tailoring, and demographic moderators were examined by analyzing between-group variance and meta-regression.
Clinically and statistically significant overall effect sizes were found across each of the four behaviors. While effect sizes decreased after intervention completion, dynamically tailored interventions were found to have increased efficacy over time as compared with tailored interventions based on one assessment only. Study effects did not differ across communication channels nor decline when up to three behaviors were identified for intervention simultaneously.
This study demonstrates that computer-tailored interventions have the potential to improve health behaviors and suggests strategies that may lead to greater effectiveness of these techniques.

    ABSTRACT: Internet based interventions promoting healthy lifestyle changes are well documented within the last years, especially using online platforms as well as applications for mobile devices. They are used in primary, secondary as well as tertiary prevention to support people in leading a healthier lifestyle and adhering to medication. To communicate relevant messages and information for the user without involving personal counseling, the content is often personalized. These so called tailored eHealth or online interventions are a promising approach to improve intervention effects and adherence. Increasing the level of tailoring of the intervention seems to be beneficial for intervention effects when considering each participant. But this practice also leads to methodological issues concerning the general comparability of the results. This is a direct consequence of tailored content based on prior assessments and indications instead of providing one intervention for all. We discuss pros and cons of such interventions as well as ways to increase the comparability of different tailored interventions. The discussion tries to advance the research field by critically appraising this approach and providing suggestions to tackle the addressed problems. These include the use of standardized taxonomies as well as adjusting the sample size or study design to adequately reflect the research goal and planned analysis of subgroups or individuals.

    • "According to surveys published by the European Commission, > 70% of people in the Netherlands, Southeastern Europe, and Denmark are reported to have searched the Internet for health-specific information during the past year [17]. Interventions encompassing more readily available ICTs enable efficient delivery of authoritative educational resources , individually tailored health and wellness programs in addition to time-unlimited feedback, coaching, and support [18] [19] [20]. Furthermore, there is growing evidence that healthrelated social media channels and similar online communications are useful in helping to promote health literacy, thereby fostering improvements in self-efficacy, self-care behaviors, and health status [16] [21].

    ABSTRACT: Abstract Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality worldwide yet the majority of related risk factors are largely preventable (primary prevention [PP]) and effectively treatable (secondary prevention [SP]) with healthy lifestyle behaviors. The use of information and communication technology (ICT) offers a unique approach to personal health and CVD prevention, as these mediums are relatively affordable, approachable, and accessible. The purpose of this review is to provide an overview of ICT-driven personal health technologies and their potential role in promoting and supporting self-care behaviors for PP and SP of CVD. In this review, we focus on technological interventions that have been successful at supporting positive behavior change in order to determine which tools, resources, and methods are most appropriate for delivering interventions geared towards CVD prevention. We conducted a literature search from a range of sources including scholarly, peer-reviewed journal articles indexed in PubMed and CINAHL, gray literature, and reputable websites and other Internet-based media. A synthesis of existing literature indicates that the overall efficacy of ICT-driven personal health technologies is largely determined by: 1) the educational resources provided and the extent to which the relayed information is customized or individually tailored; and 2) the degree of self-monitoring and levels of personalized feedback or other interactions (e.g. interpersonal communications). We conclude that virtually all the technological tools and resources identified (e.g. Internet-based communications including websites, weblogs and wikis, mobile devices and applications, social media, and wearable monitors) can be strategically leveraged to enhance self-care behaviors for CVD risk reduction and SP but further research is needed to evaluate their efficacy, cost-effectiveness, and long-term maintainability.

Computer-based interventions can assess and create a user model to deliver tailored information and dynamically update the user profile over multiple adaptive sessions (Yasavur, Amini, & Lisetti, 2012).

    ABSTRACT: Cyberpsychology is a recent branch of psychology whose main research objects are the processes of change induced by new technologies. Some of these processes are related to and involve a variety of affective processes. The discipline’s overlap with affective computing and human-computer interaction in general are significant, yet its psychological origins suggests that the research communities have somewhat different focus. In this chapter we review these histories, and discuss the similarities and differences that are currently found in the two bodies of literature. We focus in particular on how technologies can be used to help people change behavior in both clinical situations (cybertherapy) and in personal development (positive technology/computing and smart health).
