Psychometric Properties of the Greek Version of the Inpatient Dignity Scale

Background/Objectives: Patient dignity is one of the central values in nursing, equivalent to justice, freedom, and individuality. The purpose of this study was to investigate the psychometric properties of the Greek version of the Inpatient Dignity Scale (IPDS). Methods: In this descriptive, cross-sectional study, 280 patients from three Hemodialysis Units (HD) completed the IPDS, a self-completed questionnaire assessing patients' expectations regarding dignity and patients' satisfaction with dignity. Items are categorized into four dimensions, both for expectations and satisfaction: Respect as a Human Being, Respect for Personal Feeling and Time, Respect for Privacy, and Respect for Autonomy. For the translation into Greek, a double forward-backward translation process was followed, and subsequently, cultural adaptation was carried out. Construct validity was tested using the Confirmatory Factor Analysis (CFA) conducted in AMOS 26.0. Convergent validity was assessed through correlations with the Caring Behaviors Inventory-16 (CBI-16) and correlations between the dimensions of the IPDS. Repeatability was assessed using the Intraclass Correlation Coefficient (ICC), and internal consistency using Cronbach's alpha. The SPSS 26.0 statistical program was used for the descriptive and correlational analyses (p < 0.05). Results: The mean age of participants was 64.8 years old. CFA revealed an acceptable fit for the questionnaire (CFI 0.92-0.93, TLI 0.91-0.94, and RMSEA < 0.08 for both expectations and satisfaction). The IPDS was significantly and positively correlated with the CΒΙ-16, indicating good convergent validity. Cronbach's alpha was >0.70 in all dimensions of the IPDS, indicating good internal consistency. Conclusions: The Greek version of IPDS is a valid and reliable tool to measure patients' perceived dignity.
