'Development and Psychometric Testing of the Lean Management Scale for Nursing Services in Hospitals'.

Abstract

The aim of this study is to develop a new instrument (The Lean Management Scale for Nursing Services in Hospitals- LMS-N) to evaluate the lean levels of nursing services in hospitals and to evaluate its psychometric properties. A three-phase construct was used to develop this scale and to determine its psychometric properties: (1) creating the item pool, (2) preliminarily evaluating items and (3) evaluating psychometric properties. This methodological study evaluated the scale's face, content and construct validities, internal consistency, and temporal stability. The psychometric properties of the scale were tested with a total of 695 nurses in different sample groups. Data were collected between 18 November 2020 and 15 May 2021. The scale's content validity index was 0.75. According to principal component analysis, the scale included 22 items and five subdimensions, and the total variance was 60.32%. In confirmatory factor analysis, the fit indices were good or acceptable for this construct. Its internal consistency was good or acceptable according to reliability analysis. Test-retest showed that the scale had temporal stability. Lean Management Scale in Nursing Services in Hospitals is a valid and reliable tool that can evaluate the level of leanness of nursing services. It provides a comprehensive evaluation with five subdimensions: management support, visual stock management, work environment layout, preventive notification system and waste detection.
