Questionnaire Analysis

The Comprehensive Assessment of Satisfaction with Care (CASC-61) questionnaire was developed by Bredart and colleagues in 1998 and consists of 61 items selected from existing patient satisfaction questionnaires. It is organized into three parts: the first concerns doctors, the second concerns nurses, and the third covers hospital services and overall satisfaction. It is a multidimensional questionnaire, including multiple aspects related to the care provided. The CASC-61 is completed by patients after their hospitalization, although patients may also fill it out during their hospital stay.

Objective of the Questionnaire

The main goal of the CASC-61 is to assess the overall satisfaction of patients with their hospitalization. It primarily focuses on evaluating the impact of various interventions aimed at improving the quality of life in cancer patients.

Scoring and Statistical Analysis

Responses to the CASC-61 are provided on a 5-point Likert scale, ranging from 1 = poor quality of care to 5 = excellent. The total score is calculated as the total or average of the responses for each subscale, representing the patient’s satisfaction level. A higher score indicates a higher level of satisfaction.

Validity and Reliability

The questionnaire is valid, with the correlation coefficient between the subscales being adequate, ranging from 0.62 to 0.73. Furthermore, it is reliable, with Cronbach’s alpha greater than 0.85 for all subscales and equal to 0.97 for the entire questionnaire. The CASC-61 was also validated in Greek by Kritsotakis and colleagues in 2009.
