Multivariable linear regression analysis of factors associated with the Clance Imposter Syndrome Assessment score^a

Variables	Regression coefficient (95% CI)	Partial r2b	p valuea
Intolerance of Uncertainty Scale	0.34 (0.16 to 0.51)	0.13	< 0.01
Personal Optimism and Self-Efficacy Optimism Scale (total)c	-0.70 (-1.0 to -0.35)	0.14	< 0.01
Supervising trainees
Yes	Reference value
No	0.84 (-2.0 to 3.7)	0.003	0.57
Marital status
Married	Reference value
Other	-3.2 (-6.9 to 0.40)	0.03	0.08

^aThe adjusted r² represents the goodness-of-fit for the model as a whole after adjusting for explanatory variables; in this model, the adjusted r² was 0.40. This suggests that all the terms in this model, taken together, account for about 40% of the variance.

^bThe partial r² represents the proportion of variance explained by each independent variable, such that a partial r² of 0.13 suggests that factor would account for 13% of the variance in the sample.

^cThe personal optimism and self-efficacy optimism subscales were dropped from the final model because of collinearity with the total score.
