Parallel mediation analyzes testing indirect effects of anxiety and perceived competence (PC) on the association between Impostor Phenomenon (IP) and willingness to communicate (WTC).

N = 400. Bold coefficients: bootstrapped 95% CI (k = 5,000 samples) excludes zero. The χ2 model test indicated that the mediation model was superior to a null model assuming no associations among the study variables (χ2 = 498.09, df = 9, p < 0.001). The covariate gender had an effect of b = −0.26 (β = −0.13, p = 0.011) in the baseline model and b = −0.20 (95% CI [−0.343, −0.055], SE = 0.073, p = 0.007) in the mediation model.
