[Validity and Reliability of a Nursing Process Scale].

BACKGROUND

A valid and reliable nursing record audit tool can simplify nursing records and provide a basis for quality auditing.

PURPOSE

To ensure the validity and reliability of the Nursing Process Scale to promote accurate monitoring of nursing record quality.

METHODS

This study employed structural equation modeling to examine the content validity and reliability of the current Nursing Process Scale. A total of 660 results from a medical center were used to revise the content and then the validity and reliability of the revised scale were analyzed. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used in three stages, namely item generation and content validity testing, item analysis and validity testing, and reliability testing.

RESULTS

Validity, reliability, and organization based on clinical practice were used to identify and remove scale items with low factor loadings. The remaining items were organized under several factors in the revised Nursing Process Scale, which had good internal consistency with a Cronbach's α of .653 in the EFA, a Kaiser-Meyer-Olkin value of .614, and a significant Bartlett's test of sphericity value. Five factors and 22 questions were extracted from the original 32 questions. The CFA conducted after the model correction reduced the number of questions to 10 and the number of factors to 3, with each index reaching the ideal level. To improve ease-of-use in clinical settings, the important items were reduced from 32 to 22 questions, including the 10 questions suggested by the CFA.

CONCLUSIONS

The validity, reliability, and organization based on clinical practice were considered in the removal of items with low factor loadings. Axial conversion was used to generate a component matrix, which allowed item rearrangement across factors and the revision of the Nursing Process Scale. The development of simple valid and reliable audit tools will save auditor time and allow the effective evaluation of nursing record quality and improvement in record integrity. This revised scale was reviewed and approved for implementation in 42 clinical wards.
