Turkish Validity and Reliability Study of the Cancer Care Evaluation Scale

Abstract

Purpose: The aim of the study is to adapt the “Cancer Care Evaluation Scale” to Turkish and to test its validity and reliability.

Methods: The research was conducted methodologically. The data of the study were obtained from patients in a university hospital in eastern Türkiye between January and April 2023. The research was carried out with 350 people who met the inclusion criteria. The data were collected by the researchers using the “Patient Information Form” and the “Cancer Care Evaluation Scale.” Content validity index (CVI), Bartlett’s test of sphericity, Kaiser–Meyer–Olkin (KMO) index, and confirmatory factor analysis (CFA) were used to find out the content and construct validity. Cronbach’s alpha coefficient, split-half reliability analysis, and correlation analysis were used to test reliability.

Results: As a result of the evaluations and analyses, the CVI of the scale was found to be as 0.94. The Cronbach’s alpha value of the subdimensions of the scale ranged from 0.843 to 0.975 and the total Cronbach’s alpha value was found to be 0.948. In the split-half reliability analysis, Spearman–Brown’s coefficient was found to be 0.989. The fit index values were found to be as follows: X²/SD = 2.57, RMSEA = 0.067, GFI = 0.83, CFI = 0.955, and SRMR = 0.062. CFA results showed good fit index values.

Conclusion: As a result of the research, the factor structure of 35 items and 12 subdimensional scales was confirmed by CFA. It was determined that the Turkish version of the Cancer Care Evaluation Scale is a valid and reliable measurement tool to evaluate the care of cancer patients. The scale allows the care offered to cancer patients to be evaluated from the patient’s perspective. For this reason, it is thought that the scale will contribute to the identification of deficiencies in care and the improvement of the quality of care.
