Psychometric evaluation of the Nurse Spiritual Care Therapeutics Scale.
To measure nurse-provided spiritual care, robust instrumentation is needed. This study psychometrically evaluated an instrument that operationalizes frequency of nurse-provided spiritual care, the Nurse Spiritual Care Therapeutics Scale (NSCTS). The 17-item NSCTS, with an established content validity index of 0.88, was administered online to registered nurses (RNs) in four hospitals. Responses from 554 RNs (24% response rate), most who identified as Christian, provided evidence for the NSCTS' reliability and validity. Internal reliability was supported by an alpha coefficient of .93. Validity was evidenced by item-total correlations ranging from .40 to .80, low to modest direct correlations between the NSCTS and Daily Spiritual Experience Scale and Duke University Religiosity Index, and strong loadings between 0.41 and 0.84 on one factor (explaining 49.5% of the variance) during exploratory factor analysis.
