This study investigates the effect of interaction with the large language model ChatGPT on users' mood. Using a quasi-experimental pretest-posttest design, 28 participants aged 18–35 completed the Positive and Negative Affect Schedule (PANAS) before and after an 8–10-minute open-ended conversation with ChatGPT. Results indicated a statistically significant increase in positive affect and a decrease in negative affect, with medium to large effect sizes. These findings suggest the potential of AI-driven conversational agents to positively influence mood and contribute to digital mental health interventions.
