Health-compromising behaviors are difficult to change, and motivation to change is not sufficient. Unforeseen barriers emerge, and people might give in to temptations. Good intentions need behavioral support to be translated into action. Advances in human-computer interaction, as well as eHealth or mHealth applications, open a promising agenda for precision behavior change. Studies will be reported that examine the role of theoretical constructs, mechanisms, and digital interventions in the initiation and adherence to health behaviors (e.g., physical exercise, dietary behaviors, hygiene, smoking cessation). The general aim is to examine the requirements and effects of web-based precision behavior change, based on various behaviors, time spans, and samples from different countries. The Health Technology Adoption and Maintenance (HTAM) model serves as one possible backdrop of the studies, making distinctions between (a) preintentional motivation processes that lead to a behavioral intentions, and (b) postintentional volition processes that lead to the actual health behaviors.
