Examination of Reliability and Validity of the Japanese Version of the Protective Nursing Advocacy Scale(PNAS)

Abstract

    Hanks （2010） developed the protective nursing advocacy scale (PNAS), an instrument for assessing how nurses advocate on behalf of the rights and dignity of patients. We sought to enhance the Japanese version of the PNAS by examining its internal consistency and construct validity. A questionnaire survey was conducted on operating room nurses nationwide, 443 people were analyzed. As a result of factor analysis by Principal axis method promax rotation, 28 items of 4 factors were adopted. As a result of confirming the reliability, the Cronbachʼs α coefficient of the entire scale was 0.85, and the subscale was 0.73 to 0.90. Confirmatory factor analysis showed reasonable suitability. The reliability and validity of this scale have been confirmed to be statistically acceptable and can be used as an indicator of the degree to which nurses perform their role in advocating for the rights and dignity of patients.
