Scholars of communication, teaching, and learning have been calling for more research on the instructor-student relationship to be studied from an interpersonal perspective. To answer these calls, we conducted a two-step scale development study, first to derive participant-generated responses concerning undergraduate student relational maintenance behaviors and second to construct and validate a scale concerning those behaviors. Of additional interest was to explore reasons as to why students aim to maintain these relationships. A 19-item measure titled the Student Relational Maintenance Scale was created, consisting of making connections, respectful behavior, classroom participation, expressing gratitude, and classroom effort. Additionally, results revealed that both professional reasons and personal reasons motivated students to build these relationships. The results of this study provided further insight into how and why undergraduate college students build positive interpersonal connections with their instructors.
