Reliability and Validity of the Indonesian Version of the McCloskey/Mueller Satisfaction Scale

Abstract

Aim. To examine the reliability and validity of the Indonesian translation of the McCloskey/Mueller Satisfaction Scale. Background. The McCloskey/Mueller Satisfaction Scale is an instrument to measure nurses’ feelings about their job. Although the instrument has existed for a long time, there has been a lack of studies using this questionnaire in Indonesia due to the limitation of instrument validation in the Indonesian version. Therefore, it is necessary to investigate the validation and reliability of the instrument. Methods. The instrument was validated with a cross-sectional study of 350 nurses. For purposes of transcultural adaptation and psychometric validation, a forward-back translation strategy was used in conjunction with an expert panel and a cross-sectional study. The validity of the construct was verified using confirmatory factor analysis, and the overall fit of the model was measured using the calculated fit indices. The standard deviation of the extracted variance was used to evaluate the convergence validity. Composite reliability and Cronbach’s alpha coefficients were used to investigate the internal consistency of the study. Results. According to the results of the reverse translation, the Indonesian and original instruments are statistically indistinguishable. As a result of the confirmatory factor analysis, it was determined that the Indonesian version of the McCloskey/Mueller Satisfaction Scale adhered closely to the original structure of the English version. The convergence validity of the construct (0.44–0.74), reliability (Cronbach α = 0.69–0.93), and internal consistency (0.49–0.79) were rated highly. Conclusions. Good homogeneity and construct validity have been shown for the Indonesian translation of the McCloskey/Mueller Satisfaction Scale in the context of healthcare practice and research. Implications for Nursing Management. Nursing policymakers in Indonesia can use the instrument to inform the development of practice policies aimed at improving job satisfaction among nurses in the country.
