The purpose of this pilot randomized control trial was to test the initial efficacy of a 10 week social cognitive theory (SCT)-based intervention to reduce workplace sitting time (ST). Participants were currently employed adults with predominantly sedentary occupations (n=24) working in the Greater Phoenix area in 2012-2013. Participants wore an activPAL (AP) inclinometer to assess postural allocation (i.e., sitting vs. standing) and Actigraph accelerometer (AG) to assess sedentary time for one week prior to beginning and immediately following the completion of the 10 week intervention. Self-reported measures of sedentary time were obtained via two validated questionnaires for overall (International Physical Activity Questionnaire [IPAQ]) and domain specific sedentary behaviors (Sedentary Behavior Questionnaire [SBQ]). SCT constructs were also measured pre and post via adapted physical activity questionnaires. Participants were randomly assigned to receive either (a) 10 weekly social cognitive-based e-newsletters focused on reducing workplace ST; or (b) similarly formatted 10 weekly e-newsletters focusing on health education. Baseline adjusted Analysis of Covariance statistical analyses were used to examine differences between groups in time spent sitting (AP) and sedentary (AG) during self-reported work hours from pre- to post- intervention. Both groups decreased ST and AG sedentary time; however, no significant differences were observed. SCT constructs also did not change significantly between pretest and post test in either group. These results indicate that individualized educational approaches to decreasing workplace sitting time may not be sufficient for observing long term change in behaviors. Future research should utilize a larger sample, measure main outcomes more frequently, and incorporate more environmental factors throughout the intervention.

This study applied the Social Cognitive Theory (SCT) to explore the sources of self-efficacy and professional development activities that are most predictive of PreK-6 music teachers’ efficacious beliefs. This study also compared teacher efficacy levels across different groups. The target population for this study was PreK-6 music teachers in the state of Arizona. The survey was disseminated through the National Association for Music Education (NAfME), the Arizona chapters of the American Orff-Schulwerk Association (AOSA), the Organization of American Kodály Educators (OAKE), and snowball sampling via a Facebook message. Of the 660 teachers invited to participate, 92 (13.94%) voluntarily completed the survey. Results from simultaneous multiple regression analyses indicated that teacher efficacy for instructional strategies was best predicted by their mastery experience, followed by vicarious experience, while mastery experience was the strongest predictor of teacher efficacy for student engagement. Additionally, the acquisition of method certification and watching teaching resources via YouTube were significant predictors of teacher efficacy for instructional strategies, while observation hours per year was the only predictor of teacher efficacy for student engagement. Results from factorial between-subjects ANOVAs indicated that teaching experience had a significant main effect on teacher efficacy for instructional strategies and student engagement. However, neither main teaching areas nor the combined effects of main teaching areas and teaching experience had a significant effect on teacher efficacy for instructional strategies and student engagement. Results from independent-samples t-test analyses showed that school types had a significant effect on teacher efficacy for student engagement, while no differences were found between school types regarding teacher efficacy for instructional strategies. The analysis of open-ended comments identified themes related to factors that strengthen or weaken participant teacher efficacy, the impact of the COVID-19 pandemic on teacher efficacy, the types of professional development activities that they engaged during the year, the most effective professional development activities for enhancing teacher efficacy. Findings of this study have theoretical and practical implications for school principals, school administrators, policy makers, music teacher educators, and music teachers to promote and support music teachers’ self-efficacy.
