The purpose of this study was to determine the relationship between student-environment fit and physical self-efficacy among female undergraduate students living in the Trane and Tichenor wellness residence halls at Ball State University. This study examined the following questions: 1) What is the degree of fit experienced by female students living in the Trane and Tichenor wellness residence halls?, and 2) Is there a relationship between student-environment fit and physical self-efficacy? Student-environment fit is necessary for a student's happiness, satisfaction, and achievement. Physical self-efficacy is an important component of positive self-concept and has been correlated with the healthy development of an individual. Data on student-environment fit was collected using the University Residence Environment Scale. The Physical Self-Efficacy Scale was used to collect data on the students' perceptions of their physical ability and self-presentation confidence. Statistical analysis of the data revealed: 1) significant t-scores for the degree of fit experienced by female students in Trane and Tichenor wellness residence halls, and 2) a significant correlation between the total student-environment fit score and the total physical self-efficacy score as well as a significant correlation for the URES subscales of Academic Achievement and Intellectuality with the total physical self-efficacy score.
