Abstract
Importance: Physician burnout has reached crisis levels. Supportive leadership is one of the strongest drivers of physician well-being, and monitoring supervisor support is key to developing well-being focused leadership skills. Existing measures of leader support were designed within "direct report" supervision structures limiting their applicability to matrixed leadership reporting structures where direct reports are not the predominant norm. Antecedently, no measure of leadership support is validated specifically for implementation in matrixed leadership structures.
Objective: Adapt and validate the Mayo Leadership Impact Index (MLII) for settings with matrixed leadership structures.
Design: A psychometric validation study utilizing classical test theory and item response theory.
Setting: A tripartite hospital system in the southwestern US.
Participants: Physician-respondents to a 2023 cross-sectional survey.
Main outcomes and measures: After pilot testing, the adapted MLII was examined using a unidimensional graded response model and confirmatory factor analyses. Convergent validity was investigated via correlations with professional fulfillment, perceived autonomy support, self-valuation, and peer connectedness/respect. Divergent validity was tested via correlations with burnout.
Results: Of the three candidate revisions of the MLII, the 9-item adaptation was selected for its superior validity/reliability indices. Standardized Cronbach's and Ordinal alpha coefficients were 0.958 and 0.973, respectively. CFA loadings exceeded 0.70 (p < 0.001), and coefficients of variation (R2) exceeded 0.60 for all items. GRM slope parameters indicated "high" to "very high" item discrimination. Items 2, 5, and 8 were the most informative. Positive correlations of the adapted MLII with professional fulfillment, perceived autonomy support, and peer connectedness/respect were observed, supporting convergent validity. Negative correlation with overall burnout supports divergent validity.
Conclusions and relevance: The findings provide evidence of the adapted MLII's validity, reliability, and appropriateness for implementation within matrixed leadership settings. Prior to this study, no leadership support measure had been validated for use among the growing number of healthcare systems with matrixed leadership reporting structures.
期刊介绍：
Efficient and successful modern healthcare depends on a growing group of professionals working together as an interdisciplinary team. However, many forces shape the delivery of healthcare; changes are being driven by the markets, transformations in concepts of health and wellbeing, technology and research and discovery. Dynamic leadership will guide these necessary transformations. The Journal of Healthcare Leadership is an international, peer-reviewed, open access journal focusing on leadership for the healthcare professions. The publication strives to amalgamate current and future healthcare professionals and managers by providing key insights into leadership progress and challenges to improve patient care. The journal aspires to inform key decision makers and those professionals with ambitions of leadership and management; it seeks to connect professionals who are engaged in similar endeavours and to provide wisdom from those working in other industries. Senior and trainee doctors, nurses and allied healthcare professionals, medical students, healthcare managers and allied leaders are invited to contribute to this publication
