Cultural Adaptation and Assessment of the Psychometric Properties of the Greek Version of the Perceived Quality of Patient-Centered Care Among Cancer Survivors

TL;DR

This study adapts and validates a Greek version of a scale to measure patient-centered care quality for cancer survivors.

Contribution

The study provides a culturally adapted and psychometrically validated Greek version of the QPCC scale for cancer survivors.

Findings

The Greek QPCC scale demonstrated high internal consistency with a Cronbach’s α of 0.946.

Exploratory factor analysis identified 10 factors with minimal cross-loading.

Six modifications were made to the original English version for better cultural fit and interpretation.

Abstract

Background: No specific scale exists to assess the perceived quality of patient-centered care in Greek cancer survivors.

Aim: The purpose of this study was the cultural adaptation of the Quality of Patient-Centered Care (QPCC) scale and the assessment of the psychometric characteristics of the QPCC scale among Greek cancer survivors.

Sample and methods: A total of 400 cancer survivors with solid tumors were being treated at one hospital located in Athens, the capital of Greece, and participated in the validation study. The English version of QPCC was used after permission which had been obtained from the original developers. Participants completed the 48-item scale of QPCC as well as questions about sociodemographic characteristics and clinical characteristics. The validity of the scale's structure was evaluated using exploratory factor analysis, a method that identifies key dimensions measured by the tool, and the internal consistency of scale and sub-scales was estimated using Cronbach’s α.

Results: Exploratory factor analysis (Kaiser-Meyer-Olkin (KMO) = .791 and Bartlett test = 10093.336, df = 1035, p<0.01) with principal component extraction and varimax rotation revealed 10 factors with little cross-loading. Cronbach’s α for internal consistency of the whole scale was 0.946, which proved satisfactory. The lowest value of Cronbach’s coefficient was observed in the “equitable care” factor whilst the highest value was observed in the “timely care” factor. Finally, 45 items were identified. The results indicated six changes in the total of the English version such as the deletion of three items, the change of the positive wording of one item, and the transfer of two items in different factors due to better interpretation.

Conclusions: The Greek version of the QPCC scale is reliable and suitable for use among Greek patients with solid cancers.
