[Reliability and Validity Testing of the Taiwanese Inpatient Nursing Care Satisfaction Scale: A Pilot-Study].

ABSTRACT

BACKGROUND: Inpatient nursing care satisfaction is an important indicator of medical care quality. However, no reliable and validated tool is currently available in Taiwan to measure the satisfaction of inpatients with nursing care. PURPOSE: This pilot study developed a reliable and validated scale for measuring inpatient nursing care satisfaction in Taiwan. METHODS: First phase literature review and expert focus group discussion constructs the content of the questionnaire to be used to assess inpatient nursing care satisfaction. Second phase experts were requested to validate questionnaire content. Third phase convenience sampling was used to recruit 766 inpatients from 6 hospitals to complete the validated questionnaire. The data collected from the questionnaire were analyzed using item analysis, construct validity, and internal consistency. The results of analysis were used to determine the reliability and validity of the developed scale. RESULTS: The 20-item Taiwanese inpatient nursing care satisfaction scale was developed, with a CVI (content validity index) of expert validity of .97, item discrimination CR (critical ratio) of 28.61-50.25 (p < .001), and item-total correlation of .68-.84 (p < .001). Two factors, including "professional knowledge & skill" and "environmental control" were extracted by exploratory factor analysis after the deletion of 5 items, with item factor loadings ranging from .61 to .84. The factors explained 71.40% of total variance. The internal consistency of the two categories of Cronbach's α was .94-.97 coefficient and the overall internal consistency coefficient was .97. CONCLUSIONS/IMPLICATIONS FOR PRACTICE This study confirms the validity of the developed Taiwanese inpatient nursing care satisfaction scale and suggests that this instrument is reliable for measuring the satisfaction of inpatients with nursing care in Taiwan.
