This study examined the relationship between individual personality traits and preferences for positive activities, drawing on trait theory and typology perspectives. An online survey was conducted by a Japanese market research company, with Japanese participants (N=934, 508 men, 426 women) ranging in age from 15 to 91 years. Participants completed the Japanese version of the Ten-Item Personality Inventory (TIPI-J) and the Person-Activity Fit Diagnostic. Multiple regression analysis revealed that agreeableness was the strongest predictor of preferences for all positive activities. In addition, a cluster analysis identified four prototypes of Big Five personality traits: Not Identifiables, Undercontrollers, Resilients, and Overcontrollers. An analysis of variance demonstrated that Resilients exhibited the highest preferences for positive activities. These findings indicate that agreeableness plays a significant and consistent role in preferences for positive activities, as supported by both trait theory and typology perspectives.
