Spatial distance facilitated hedonic editing, which was indicated by systematic memory biases in users' recall of positive and negative self-tracking outcomes. We analyzed data using chi-square tests (SPSS version 23) and moderated mediation analyses with the PROCESS macro 2.16.1. Variables of interest measured were health behavior intentions, compensatory health beliefs, health motivation, and recall of the outcome profile. Thereafter, participants saw one of four manipulated self-tracking outcome profiles. The experiment started with a cover story about a fictitious self-tracking app. To assess users' responses to a spatially close (vs distant) presentation of a mixed-gain (vs mixed-loss) self-tracking outcome profile, a randomized 2×2 between-subjects online experiment with a final sample of 397 participants (mean age 27.4, SD 7.2 years 71.5%, 284/397 female) was conducted in Germany. ![]() Further, this study examined how the opportunity to hedonically edit one's self-tracking outcome profile relates to users' future health behavior intentions. ![]() This study examined whether a spatially close (vs distant) presentation of mixed positive and negative self-tracking outcomes from multiple domains (ie, activity, diet) on a digital device's screen can provide users the opportunity to hedonically edit their self-tracking outcome profile (ie, to view their mixed self-tracking outcomes in the most positive light). For these techniques to be effective, it is relevant to understand how the visual presentation of goal-related outcomes employed in the app design affects users' responses to their self-tracking outcomes. Goal setting is among the most common behavioral change techniques employed in contemporary self-tracking apps.
