Self-determination theory provides an important lens through which to study the possible association between microbreaks and work performance. Self-determination theory states that when an individual's needs for autonomy, competence, and relatedness are satisfied the individual will have intrinsic motivation which will drive performance. In this experience sampling study, I recruited employees to respond to four surveys per day for five days. Based on the results of 100 participants, using unconflated multilevel modeling I found that higher work engagement covaried with higher personal initiative. Using multilevel structural equation modeling and focusing on between-person relationships, I found that autonomy need satisfaction during microbreaks covaried with increased intrinsic work motivation, while relatedness covaried with decreased intrinsic work motivation. Also, focusing on the between-person relationships, higher intrinsic work motivation covaried with higher work engagement, which then covaried with higher personal initiative. At the between-person level autonomy influenced personal initiative indirectly via enhancements in work engagement extending from intrinsic motivation. In this dissertation, I provided a comparative analysis of microbreak activities and implications of need satisfaction on various work-related constructs.ETDenIn CopyrightMicrobreaksPerformanceSelf-determination theoryDissertation
