Introduction:
Uncertainty in medical practice affects physicians' well-being and decision-making. The Physicians' Reactions to Uncertainty (PRU) scale measures affective and behavioural reactions to uncertainty, but no Danish version exists. This study aimed to translate, culturally adapt and validate the PRU.
Methods:
The PRU was translated and culturally adapted in accordance with international guidelines. A pilot test assessed face validity. Reliability and validity were examined in a cross-sectional study with 116 physicians using Cronbach's alpha, the intraclass correlation coefficient (ICC) and confirmatory factor analysis (CFA).
Results:
A Danish version (PRU-DK) was developed with minor linguistic adjustments. It showed strong internal consistency (Cronbach's α ≥ 0.75 across subscales) and high item correlations (Spearman's ρ = 0.68-0.93). Test-retest reliability was high (ICC > 0.80 for all subscales except Reluctance to disclose mistakes to physicians, ICC = 0.56). CFA supported the four-factor model (χ²/df = 1.66, Comparative Fit Index = 0.923, Tucker-Lewis Index = 0.901, Root Mean Square Error of Approximation = 0.076, Standardised Root Mean Square Residual = 0.073). Inter-subscale correlations ranged from 0.16 to 0.62.
Conclusions:
The PRU-DK is a validated and reliable tool for assessing Danish physicians' reactions to uncertainty, demonstrating solid psychometric properties and acceptable model fit. The original structure was preserved to enable comparison, but periodic revision is warranted to address cultural shifts and refine behavioural components.
