Evidence-Based Practice Section G: Evaluation Section G -- Evaluation

Methodology and data collection rationale. The role of leadership styles and training in nursing situations has been described in the literature and there is a substantive body of work suggesting that leadership can significantly affect the praxis of nurses and the outcomes of patients (Looke, 2001). Training that occurs over time is believed to enhance adoption of desirable behaviors in the workplace environment, and to strengthen the implementation of transformational leadership (Bowles & Bowles, 2000). Because individuals develop leadership skills over time, it is rational to survey nurses who receive training in transformational leadership at intervals during and after training to assess their levels of transfer of training to practice. The Leadership Practices Inventory (LPI) will be used to conduct face-to-face interviews of nurses receiving training in transformational learning. Use of the LPI will broaden and deepen...

In addition, surveys designed to assess formative mastery of the transformational leadership curricular content will be employed.
Evaluation of extent of achieved objectives. The purpose of the research is to provide greater knowledge of the training and development practices that lead to lower rates of attrition amongst nurse management and leadership. Measurement of this research goal will primarily focus on the practice and leadership differences, observed during the first two years of working in a management role, of nurses who have had training in transformational leadership and nurses who have not had this training.

Measurement and evaluation of outcomes. Explicitly, measurement of the attainment of the research objectives will focus on self-reported changes in the practice and the outlook of trained nurses, changes in work environments…

Validity. Quantitative data will be triangulated against the qualitative data collected through surveys and interviews of subjects. A baseline survey will establish levels of knowledge about the implementation of transformational training, about evidence-based practice, and about change in organizations. This first survey will strengthen the validity of subsequent surveys and interviews by establishing definitions and meaning of terminology used in subsequent surveys and interviews. The transformational leadership training itself will further solidify subjects' conceptual understanding, thereby contributing to content validity.

Interaction of testing and treatment poses the greatest threat to construct validity in this study because of the inherent need to test formative learning and the use of surveys and interviews which can function in much the same way as a test by signaling valued or awarded behaviors to subjects. Pilot testing of survey questions will contribute to construct validity.

Threats to internal validity in this study include social interaction, mortality, maturation, and testing (Carmines & Zeller, 1974). Social interactions can be a threat to internal validity if nurses who do not receive training behave differently because of
