Turkish validity and reliability study of the quality of care through the patient's eyeschemo scale: Methodological study

Turkish validity and reliability study of the quality of care through the patient's eyes chemo scale: Methodological study C hemotherapy, which is an important part of cancer treat- ment, increases survival in many cases but seriously compromises patients' quality of life and causes difficult-to-manage symptoms. [1,2]For patients and their families, adaptation can be a challenging experience. [3]The physical, sexual, and psychosocial problems caused by cancer and chemotherapy, as well as the management of these problems, can be influenced by many variables.One of these variables is the active role that patients and their families take in the process, as well as their ability to manage it. [1]Education and informa-tion about cancer and the treatment process are crucial in supporting patients and their families. [4]rses play a key role in patient and family education. [5][6][7] Their constant and close interaction with patients, their position as implementers of treatment and managers of care, and their possession of the knowledge, skills, and competence required by their educational role place significant responsibilities on nurses at this point. [8]The chemotherapy process is one of the most challenging stages in which patients experience the fastest and most radical changes.Therefore, it is crucial for Objectives: This study aimed to assess the Turkish validity and reliability of the Quality of Care Through the Patient's Eyes chemo Scale.Methods: Conducted at a university hospital in Trkiye, the study utilized a methodological design and involved 335 chemotherapy patients in the Outpatient Unit.Data collection employed a simple random sampling method along with a "Patient Information Form" and the "Quality of Care Through the Patient's Eyes chemo Scale."Steps were taken to determine the language, content, construct validity, and reliability of the scale.Results: Patients had a mean age of 54.48 years, with the majority being female (53.1%) and married (75.8%).Breast cancer (22.1%), lung cancer (17.3%), and colon cancer (10.7%) were the most common diagnoses among patients.Content validity analysis resulted in the removal of 9 items from the 67-item scale, with a content validity index of 0.92.The suitability of the data for factor analysis was confirmed with a Kaiser-Meyer-Olkin (KMO) value of 0.936 and Bartlett's test (6042.307,p<0.000).However, in construct validity, Confirmatory Factor Analysis (CFA) fit indices, including /SS (3.963), GFI (0.674), IFI (0.690), CFI (0.788), and RMSEA (0.124), fell below acceptable limits, suggesting incompatibility of the original structure of the scale in the country.Exploratory Factor Analysis (EFA) revealed a 3-factor structure with 27 items, explaining 59.648% of the total variance.The scale demonstrated a Spearman-Brown correlation coefficient of 0.871, a Guttman equivalent halves coefficient of 0.867, and a total Cronbach's alpha value of 0.950. Conclusion:The scale is a valid and reliable tool for measuring the information and communication needs of chemotherapy patients.It is expected to serve as a guide for chemotherapy nurses in effectively assessing these needs.
