OBJECTIVES Sasang Constitution is a traditional Korean medical system that classifies individuals into four types, Taeyangin, Taeeumin, Soyangin, and Soeumin, based on physical and psychological traits. Sasang Constitution is widely used for disease prevention and treatment, emphasizing the potential of personalized healthcare. However, concerns about the accuracy and reliability of diagnostic tools like the Questionnaire for Sasang Constitution Classification II (QSCC II) persist. This study investigates the impact of an 8-week lifestyle modification on Sasang Constitution classification using QSCC II, aiming to enhance the reliability and applicability of this diagnostic tool. METHODS A total of 124 sedentary college students participated in an 8-week lifestyle modification program. The participants were assessed with the QSCC II before and after the program to detect changes in their Sasang Constitution classification. The program consisted of self-directed aerobic and resistance training, performed 3 days/week for 40 minutes, along with dietary changes based on Korean nutrition guidelines. RESULTS After 8 weeks, 33.9% of participants (42 out of 124) experienced changes in their Sasang Constitution classification, with the majority of changes observed in the Soyangin group. Decision tree analysis revealed that changes were strongly influenced by four key QSCC II items. CONCLUSIONS This study demonstrates that the lifestyle modification program influenced responses to certain QSCC II items. The observed changes in responses related to psychological and interpersonal factors may have been due to the insufficient discriminative power of the items themselves. In contrast, physical factors may be influenced by the program, suggesting that these factors could potentially impact the results of Sasang Constitution classification when using the QSCC II.
