Content validity testing of questions for a patient satisfaction with general anesthesia care instrument

J Perianesth Nurs. 2014 Feb;29(1):28-35. doi: 10.1016/j.jopan.2013.05.011.


Introduction: Patient satisfaction with any health care experience is the result of a complex set of interactions between the patient and the health system in which care is received. Measuring patient satisfaction allows quantification of the congruence between the expectations of care and the care that is received. It is important to quantify satisfaction with care because it involves the patient in the care experience and decreases the potential gap between expected and actual care delivered over time. Despite the benefits of measuring satisfaction with anesthesia care, this outcome has been historically understudied possibly because of a lack of reliable tools that measure the construct.

Purpose: The purpose of this study was to test the content validity of items derived from an integrated review of studies that measured patient satisfaction with anesthesia care.

Methods: The content validity of the questions was tested using an expert panel. A total of 13 nurse anesthetists consented to participate in the study as expert panel members. Each expert panel member evaluated the items for content validity on a 4-point scale. Both an Individual Content Validity Index (I-CVI) and a Scale Content Validity Index (S-CVI) were calculated.

Results: All I-CVI scores were greater than 0.8. The range of I-CVI was 0.833 to 1.0. The average scale Content Validity Index (S-CVI/ave) was 0.979.

Conclusion: High content validity of all items was supported by an expert panel of anesthesia providers. The high level of agreement among raters related to the content of the general anesthesia statements supports progressing to the next step in instrument development.
