“A cheerful heart is a good medicine, but a crushed spirit dries up the bone.” Health psychology explores the mutual relationship between mental and physical health. My research in this field currently focuses on the impact of thin-ideal internalization on body dissatisfaction and dieting behaviors, health-related behaviors, and emotional regulation. Methodologically, I have primarily used questionnaire surveys and employed multivariate analysis to process the data. In a more recent project, I utilize ecological momentary assessment (EMA) to capture health behaviors in situ.
