Structured AI Dialogues Can Increase Happiness and Meaning in Life
Bibliographic record
Abstract
Millions of people now use AI-powered chatbots to support their mental health, yet little is known about whether such interactions can effectively enhance psychological well-being. We conducted a preregistered experiment on a large, diverse sample (N = 2,922) to test four AI chatbots, each prompted to employ a multi-step strategy drawn from prior psychological research on sources of happiness and meaning in life. Chatbots encouraged participants to either (a) savor positive life experiences, (b) express gratitude toward a friend or family member, (c) reflect on sources of meaning in their life, or, (d) reframe their life story as a “hero’s journey.” All four chatbots led to improvements on a broad range of psychological well-being outcomes – including affective well-being, meaning in life, life satisfaction, anxiety, and depressed mood – relative to a control chatbot condition. These results generalized to key subpopulations, including those with high baseline levels of anxiety or depression. Chatbot interactions increased interest in seeing a human therapist, including among those who were previously unwilling or had never attended therapy. A separate, nationally representative survey (N = 3,056) found that half of U.S. adults expressed interest in using empirically validated AI chatbots for mental health support. These findings demonstrate that AI-driven well-being chatbots grounded in psychological research offer a scalable and effective way to produce short-term increases in several aspects of psychological well-being. Importantly, these results do not generalize to all AI-based emotional support.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
