Setting Goals and Accepting Challenges for Behavior Change—Analysis of Participants’ Interactions With a Digital Multiple Health Behavior Intervention: Mixed Methods Study
Notice bibliographique
Résumé
Background: Digital interventions are effective in promoting healthy behaviors and are recognized as one of many strategies for achieving healthier populations. These interventions often include goal-setting, but the practical application and fidelity of goal setting, especially when targeting multiple health behaviors, remain underexplored. In a factorial randomized trial, we included goal-setting as one of six behavior change components in the digital intervention "Buddy," targeting university and college students' alcohol, diet, physical activity, and smoking behaviors. However, we found no strong and consistent evidence of an effect of goal-setting alone on any of the outcomes, highlighting the need to investigate how participants used this component. Objective: This case study of Buddy aimed to gain insight into participants' interactions with the goal-setting component. Specific objectives were to identify the characteristics of participants who used this component and to analyze participants' self-authored content. Methods: This study combined fidelity and effectiveness findings and involved 1704 participants from 18 universities and colleges in Sweden. Self-authored goals and challenges were analyzed using summative content analysis. Logistic and negative binomial regression analyses were conducted to estimate the odds of setting a goal, selecting or self-authoring a challenge, to estimate the odds of setting a goal with respect to a specific behavior, and to estimate the frequency of selecting or self-authoring different behavioral challenges. Results: Of the 850 participants given access to the goal setting and challenges component, 427 (50%) set at least one goal and 403 (47%) selected or self-authored at least one challenge. A total of 607 goals were set, with most participants setting one goal (336/427, 79%). Goals primarily targeted physical activity (n=302), dietary behavior (n=140), and multiple health behaviors (n=53), typically combining physical activity with diet, alcohol, smoking, or sleep. Other goals included study performance, mental health, sleep, and mobile phone use (n=73). Fewer goals concerned alcohol (n=19) or tobacco (n=17). Participants selected 1506 challenges from 41 premade challenges, with dietary behavior challenges being most popular (667/1506, 44%). An additional 170 challenges were self-authored. Participants' baseline characteristics were associated with the odds of setting goals targeting specific behaviors and the frequency of selecting or self-authoring challenges targeting specific behaviors. Conclusions: Our analyses suggest that, while goal-setting is theoretically grounded, and participants used Buddy in ways that suited their personal needs, this did not translate to measurable behavior change in the study population. The self-authored content showed how participants used the component and provided insights into how they articulate behavior change in terms of personal goals, challenges, strategies for action, motivation plans, and rewards. Future research should explore the conditions under which goal-setting may be more or less effective, to better understand its nuances and potential benefits.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
