Development of the Perioperative Privacy Scale: A Validity and Reliability Study

Abstract

PurposeThis study aims to develop the Perioperative Privacy Scale and test its validity and reliability. DesignThis is a methodological study. MethodsThis study was conducted with 298 patients who were hospitalized in surgical clinics in a university hospital, met the inclusion criteria, and agreed to participate in the study. The data were collected using a personal information form and the Perioperative Privacy Scale developed by the researchers. This methodological study was conducted between August 2019 and March 2020. The items of the scale were determined after a literature review and qualitative interviews with the patients. The draft version created to test the scale's content and face validity was reviewed by 11 experts (faculty members). Six items were omitted from the 37-item pool and revisions were made based on the experts’ opinions and recommendations. Data analysis was conducted using the content validity index specially for content validity, and exploratory and confirmatory factor analyses for construct validity. Reliability was assessed using Cronbach's Alpha, Spearman Brown, and Guttman's coefficients. FindingsThe content validity index of the 16-item scale was 0.87. The scale explained 63.37% of the total variance and consists of 3 subscales. The scale's Kaiser-Meyer-Olkin value was 0.89, Bartlett's test was χ2 = 3834.2 (P < .05), and Anti-Image Correlation was between 0.74 and 0.97. The goodness of fit values showed that the scale was acceptable. Items and subscales were related with the scale and a three-factor structure was confirmed. Spearman-Brown was 0.87, Guttman Split-Half was 0.87, and Cronbach Alpha was 0.92 for the entire scale. ConclusionsThe Perioperative Privacy Scale is a short scale consisting of 16 items. It can be used in descriptive and experimental studies to assess the thoughts of inpatients in surgical clinics regarding privacy.
