This study explores whether personality traits and temperamental dispositions are associated with adults' use of background music in daily life. Taking an exploratory approach, we sought to identify underlying personal dispositions that may account for individual differences in everyday engagement with background music. The participants in this study were 270 Chinese adults, both male and female, aged 18 years and older. We measured participants' personality traits based on the Big Five factors, and their temperamental dispositions based on the concepts of the Behavioral Activation System (BAS) and Behavioral Inhibition System (BIS). Background music use in daily life was measured using a subscale of the Use of Music Inventory. All data were collected online following approval from the Institutional Review Board (IRB) and after obtaining informed consent from the participants. In the correlation analysis, extraversion, openness, conscientiousness, and agreeableness were found to be positively correlated with background music use in daily life, whereas neuroticism showed no significant correlation. In contrast, the temperamental dispositions of BAS and BIS were not significantly correlated with background music use. In the multiple regression analysis with the Big Five personality traits, the model accounted for 10.7% of the variance in background music use, with extraversion and openness being identified as significant predictors. These findings suggest that personality traits play a notable role in everyday background music use. Further research should focus on developing more refined instruments for assessing background music use in daily life, which would allow for a deeper understanding of its relationship with individual psychological factors.
