A sense of mattering among college students has been found to have positive outcomes, including lower levels of anxiety and depression as well as increased self-esteem, wellness, happiness, and job satisfaction. However, the feeling of mattering among Resident Assistants (RAs) has received little attention in literature. This quantitative study collected data from 74 RAs at a large, public research university in Texas to explore the relationship between RAs' feelings of mattering and their placement, individual community size, and overall area size. Results showed RAs in residence halls have higher levels of mattering compared to their apartment RA counterparts. Additionally, the results showed there is a negative relationship between RAs' feelings of mattering and both individual community size and overall area size. Implications for future research and practice are discussed. [Discussion questions developed by Diane Waryold and Pam Schreiber.]
