Abstract	The United States has a weight problem. It's not just about food intake but also about energy consumption [97, 153]. This dissertation asks: "How can we encourage people to act in ways that are mutually beneficial for themselves and the environment?" To date, there is no single behavior intervention in the literature targets behavioral changes containing both health and pro-environmental implications. Based on emerging knowledge from research in HCI, health communication, behavior interventions, psychology, pro-environmental psychology, habit formation (tiny habit theory), and experience sampling, this work describes the design and study of the EcoSante Lifestyle Intervention, a mobile behavior intervention app that engages participants with daily challenge prompts designed to engage health and environmental action simultaneously. A study of EcoSante engaged a total of 139 participants (83.5% women, 82.1% under 35 years old) in a 20-day intervention on sustainable lifestyle. Participants were asked to complete one unique behavioral challenge on sustainable lifestyle each day (e.g., challenges related to physical activity, purchasing decisions, travel mode, healthy diet). The study used a 2 x 2 design to manipulate two independent design variables: stating health benefits of a challenge with environmental benefits together (conditions 3 & 4) versus only stating environmental benefits (conditions 1 & 2); and, asking participants to complete only researcher generated challenges (conditions 1 & 3) versus challenges generated by both researcher (on odd days) and participants themselves (on even days) (conditions 2 & 4). To complete a challenge, participants were asked to record and describe what they had done in the app. Behavior changes were measured using self-reported survey data assessed at three time stamps (pre-study survey as baseline data, post-study survey, and one-month follow-up survey) on behaviors (eating, exercise, pro-environmental), self-efficacy (general and domain-specific self-efficacies), and psychological well-being. There are six major findings: (1) A total of 1,921 challenges were completed by 139 participants--the average completion rate across all 20 challenges was 69.1%. (2) There were few between-subject effects of experimental condition--stated health benefit in challenges and higher level of user-involvement during intervention did not lead to better performance in most outcome measures. (3) Participants' eating behavior (p<0.01) and general self-efficacy (p<0.05) improved right after the 20-day mobile intervention. (4) Participants' eating (p<0.01), exercise (p<0.05), pro-environmental (p<0.05) behaviors and general self-efficacy (p<0.05) improved in the delayed one-month post-intervention, comparing to where they were before participating in the intervention. (5) Domain-specific self-efficacies did not improve post-intervention nor one-month post-intervention. (6) More challenge completions led to improvement in pro-environmental behavior (b = 0.012, 95% CI = 0.0019, 0.0213). The survey and interview data along with participants' photo and challenge descriptions also have design implications. While the majority of participants enjoyed receiving a different challenge every day, the results suggest that repetition of challenges matters. Moreover, while the content variety of challenges boosted participants' motivation and engagement, no improvements were observed in participants' domain-specific self-efficacies (nutritional and physical activity self-efficacy, personal efficacy for global warming). This could be due to the gaps in participant perception of the actual number of challenge themes and its associated benefits (health and/or environmental benefits). In addition, there were more interesting learnings surrounding the challenges when participants chose to personalize/modify example challenges rather than inventing their own challenges from scratch (participants in conditions 2 and 4 were invited to generate their own challenges or modify/personalize example challenges on even days). Last but not least, activity-based photos captured by participants throughout the intervention revealed meaningful clues for researchers to better capture participants' challenge completion process (e.g., levels of user involvement, misunderstandings of challenges). My dissertation proposes a total of seven methodological and design implications in Chapter 8 (Discussions), and points out several directions for future work in Chapter 10. Findings and implications from this dissertation work contribute to habit formation, human-computer interaction, and image-based experience sampling research as well as research on mobile health (mHealth) and multiple behavior change intervention in preventive medicine.
