Cognitive biases play a significant role in the decision-making process covering medical, financial, social, and personal choices. Our review indicated that the need for reliable measures to assess perception of cognitive biases. The current study aimed to develop a self-report measure to assess the perception of cognitive biases in decision-making and to test its initial psychometric properties. In the study, exploratory factor analysis was conducted with Sample 1, while confirmatory factor analysis confirmed a six-factor model in Sample 2, showing satisfactory reliability. The total sample consisted of 453 randomly selected Turkish adults, 302 of whom are women (66.67%), and 151 are men (33.33%), with ages ranging from 18 to 65 years (M = 33.25, SD = 9.50). Cronbach’s alpha coefficient was 0.88, indicating good internal consistency. The Perception of Cognitive Biases in Decision-Making Scale (PCBDM-S) scores were found to be negatively correlated with mindfulness scores. PCBDM-S consists of six dimensions: Framing and Anchoring bias, Overconfidence bias, Sunk-Cost bias, Status-Quo bias, Confirmatory bias, and Availability bias. The findings provide preliminary evidence of the psychometric properties of the PCBDM-S, suggesting that the scale holds promise for further validation as a tool to assess perception of cognitive biases in decision-making.
