Development and Psychometric Properties Evaluation of a Care Needs Questionnaire in Phase 1 Cardiac Rehabilitation for Patients with Coronary Artery Disease: CNCR-Q

Introduction:Cardiovascular diseases (CVDs) are one of the most common chronic illnesses
and the leading cause of mortality worldwide. This study aimed to design and assess the
psychometric properties of questionnaire to examine the care needs of patients with coronary
artery disease (CAD) in phase 1 of cardiac rehabilitation (CR).
Methods:This sequential exploratory study used a mixed method with two phases. In the first
phase, qualitative study was performed by analyzing the concept of Schwartz-Barcott-Kim
hybrid model; and in the second phase, quantitative data were obtained and analyzed for the
psychometric parameters of the designed tool.
Results:The questionnaire for care needs was based on the indicators of measurement, which
was identified in the qualitative phase of the study, as a tool with 40 items. After conducting
face validity qualitatively, all tool items were considered important and were retained for the
next steps. After completing the steps for determining the content validity ratio (CVR) and
content validity index (CVI) of 40 items, they were preserved for decision making at a later
stage. The results of exploratory factor analysis revealed four factors; the factor analysis of three
items was eliminated and the final version of the questionnaire CNCR-Q (Care Needs Cardiac
Rehabilitation-Questionnaire) with 37 items remained.
Conclusion:The findings indicated that the questionnaire with properties, such as simple
scoring, reliability and validity, is an appropriate tool for assessing care needs in Iranian patients
with CAD. Moreover, the CNCR-Q is an effective instrument for assessing patient needs before
discharge.
