Background: Health promotion and growth-based interventions can effectively improve individual well-being; however, significant gaps in access and utilization still exist.
Objective: This study aims to develop and test the effectiveness and implementation of a new, widely targeted conversational agent prevention program (Zenny) designed to enhance well-being.
Methods: A total of 1345 individuals in the United States were recruited online and randomly assigned to either (1) a self-help program intervention delivered via an automated conversational agent on WhatsApp or (2) an active control group that had access to evidence-based wellness resources available online.
Article Synopsis
- The text discusses how self-control involves competing decision-making routes, specifically between default behaviors and more deliberate, effortful choices.
- It highlights the common dilemma of whether to use limited cognitive resources for immediate needs or to invest them for potentially better long-term outcomes.
- The authors propose a framework that links various models and theories from different fields, suggesting that similar mechanisms affect decision-making across diverse situations.
