RESUMEN
Objective: To develop and test the psychometric properties of the Pakistani Critical Thinking Dispositions Scale. Methods: In the item generation phase, constructs of the scale were identified through an in-depth literature review and items were written to measure the constructs. Following this, input of the experts was obtained for content validity index. In the item reduction phase, psychometric properties were measured. Initially, the scale was administered to 580 study participants during May 2018-2020 after approval from the institutional review board. Data was analyzed through SPSS v21, AMOS v21 and Omega extension. Results: First phase identified 54-items for seven constructs including contextual perspective, perseverance, reflection, intellectual integrity, creativity, open-mindedness, and inquisitiveness. Second phase determined KMO test value of 0.974 and Bartlett's test (P-Value < 0.001). The second-order confirmatory factor analysis showed a good fit model explaining 73.37% total variance. Parsimony and baseline comparison indices were favorable. Alpha and Omega value of 42-items was 0.869. Conclusion: Pakistani Critical Thinking Dispositions scale owning seven constructs and 42-items is valid, reliable, and feasible to use in undergraduate nursing education. However, its utilization in other healthcare disciplines can be tested.
