0) indicates that PTSD symptoms account for at least some of the relationship between TE and AD or ND (41). To generate empirical percentile confidence intervals (CIs) and p values for τ-τ′ since its distribution is unknown (41), we first created 1,000 bootstrapped samples. Empirical 95% CIs were then computed by ordering τ-τ′ values from the bootstrapped samples from lowest to highest; the 25th value represents the lower bound (2.5%), and the 975th value represents the upper bound (97.5%). P values reflect the percentage of bootstrapped samples with τ-τ′ ≤ 0 (i.e., the proportion of samples indicating no change in the TE effect with the inclusion of PTSD symptoms).
