The first purpose of this study was to describe collegiate band members' preferred teacher interpersonal behaviors and perceptions of self-efficacy based on the gender, year in college, instrument, and major. The second purpose of the study was to measure the relationship between preferences of interpersonal teacher behavior and self-efficacy scores. The nonprobability purposive sample (N = 1020) was composed of band members representing 12 universities from different regions of the United States. There were 4 large public, 4 small public, and 4 private universities that participated in the study. Participants completed 2 questionnaires, the Teacher Interaction Preference Questionnaire (TIPQ) and the Self-Efficacy Questionnaire (SEQ). Descriptive statistics were calculated for each of the questionnaires. Results for the TIPQ showed that all sub-groups most preferred the dominant-cooperative behaviors, followed by submissive-cooperative behaviors, and least preferred the dominant-oppositional behaviors. Results for the SEQ showed subtle variations for all subgroups. Three Pearson product-moment correlation coefficients were calculated to measure the relationship between the three teacher interaction styles (dominant-cooperative, submissive-cooperative, dominant-oppositional) and students' perceived self-efficacy. Due to the possible over-use of the data with multiple correlations, a Bonferroni adjustment was made to avoid a Type I error (.05/3 = .016). A significant positive relationship was found between self-efficacy and dominant-cooperative with 22% shared variance. A significant positive relationship was found between self-efficacy and submissive-cooperative with 7% shared variance. Finally, a significant positive relationship was found between self-efficacy and dominant-oppositional with 5% shared variance. This study's results indicate that it may be beneficial for band directors to measure students' preferences and perceptions of teacher interpersonal teacher behavior in order to find ways to interact better with the students. In addition, due to the relationship between students' preferences of teacher interpersonal behavior and perceived self-efficacy, collegiate band directors may wish to examine their own behaviors to determine how they align with the students' preferences.
