Background A good limb position (GLP) plays an important role in the rehabilitation process of patients who have had a stroke with hemiplegia. However, there remains a lack of effective assessment tools for clinical nurses to evaluate their GLP management practices.Objective This study aimed to develop and test the psychometric properties of the Good Limb Position Management Scale for Stroke Patients with Hemiplegia by Nurses (GLPMSSPHN).Design A quantitative and cross-sectional design.Setting 89 hospitals in 16 cities of China.Participants A total of 516 participants completed the questionnaire and were finally used for the analyses.Main outcome measures An initial scale was developed based on the Capability, Opportunity and Motivation-Behaviour model combined with a comprehensive literature review, semi-structured interviews, Delphi expert consultations and a pilot test. A field survey was then performed using the initial scale to test the reliability and validity of the scale. Reliability analysis was conducted by calculating Cronbach’s α coefficients and test–retest reliability. The results of exploratory factor analysis and confirmatory factor analysis were used as the validity index to further verify the model structure of the scale and develop a formal scale.Results The GLPMSSPHN was formulated with 4 dimensions and 35 items. Exploratory factor analysis extracted four factors, with a cumulative variance contribution rate of 81.842%, and confirmatory factor analysis indicated that the scale had good construct validity. The Cronbach’s α coefficient of the scale was 0.978, and the test–retest reliability was 0.863.Conclusions The GLPMSSPHN has ideal reliability and validity and provides a valid and reliable tool for clinical nurses to identify and assess the management level of GLP in patients who have had a stroke with hemiplegia.
