Nonprofit leadership attributes exert a significant effect on the nonprofit volunteer workforce to provide optimal service delivery to communities. Meeting the local community demands challenges nonprofit leadership to model inspirational behavior and attitudes that may motivate workers to transcend personal aspirations to support organizational goals more effectively. The purpose of this quantitative, correlational study was to determine whether transformational leadership influences the level of commitment and engagement of volunteer workers in nonprofit organizations. A theoretical framework based on transformational leadership guided the research. The research questions addressed the relationships between transformational leadership and nonprofit volunteer engagement and commitment. A sample of 111 U.S. volunteers provided the data by completing an online survey containing questions from the Multifactor Leadership Questionnaire 5X Short, the Utrecht Work Engagement Scale, and the Organizational Commitment Questionnaire. Simple linear regression was used to test the relationship between the independent variable, transformational leadership, and the dependent variables, engagement and commitment and their subscales. The results indicated a significant positive relationship between transformational leadership and nonprofit volunteer engagement and commitment, and transformational leadership and 8 of 9 subscales of the dependent variables. Transformational leadership positively impacts social change by effectively motivating the nonprofit volunteer workforce, thereby enhancing service delivery to local communities.
