Evaluation of the Psychometric Properties of the Malaysian Version of Ottawa Decisional Conflict Scale among Cardiovascular Patients Undergoing Major Surgery

Abstract

Background: The Ottawa Decisional Conflict Scale (ODCS) is one of the initiatives developed to determine the information about the patient's decision and the factor that influence the decision made. Therefore, a systematic and structured process of decision-making can express the difficult action to be taken by patients. Objectives: This study aimed to evaluate the psychometric properties of the Malaysian version of ODCS among cardiovascular patients undergoing major surgery. Methods: This study used the forward-backward translation method to develop an instrument that enabled Malaysians to know about this variable. Therefore, the researcher decided to make a transcultural adaptation and evaluate the decision-making of the Malaysia version of the ODCS, which seeks information about decision-making and the factors that influence the choices made. This study was conducted from January 2015 to July 2016 through a convincing sampling of 520 cardiovascular patients who need to undergo major surgery with a focus on decision-making regarding the diseases. Results: The results obtained on the reliability tests showed good internal consistency for all items (Cronbach α=0.914-0.917). From the analysis, the Kaiser-Meyer-Olkin Measure of Sampling Adequacy was 0.886, while the significant value of Bartlett's Test of Sphericity was P<0.001. Therefore, the analysis concluded that the data were appropriate for principal component analysis. Conclusion: The psychometric properties of the Malaysian version of the ODCS are considered appropriate to be administered to patients who need to undergo cardiac surgery. Patients' provision of information was able to decrease decisional conflict among them with cardiovascular disease.
