In higher education, a limited number of studies have been conducted on the relationship between lifestyle and creativity and dating back to more than 50 years ago. This study investigates the up-to-date results of the relationship between university students' lifestyles and their creative ideation. The data was collected two times in order to perform Exploratory Factor Analysis (EFA) and Hierarchical Regression Analysis. The participants consisted of 233 students for EFA, whereas regression analysis consisted of 239 students from five public universities across Thailand. The data was analyzed using 'R Programing Language' to obtain the results. The study revealed that in a collectivist culture society like Thailand, student lifestyles consist of five dimensions, i.e., family-oriented, community consciousness, modern, family concern, and traditional lifestyle. The correlation results showed that community consciousness and a modern lifestyle were significantly associated with creative ideation after controlling for gender and age variables. In contrast, family concern, family-oriented, and a traditional lifestyle were not. These findings suggest that undergraduate students who endorse modern and community consciousness lifestyles were likely to perform better in generating creative ideas.
