Reliability statistics for final PTSQ scales.

<p>Cronbach’s alpha statistics are provided for internal reliability at each age and a mean across the ages. Scales that were formed using Cronbach’s alpha analyses of the 12-month data, from items that loaded inconsistently in the PCA’s, are indicated in the Scale column by an asterisk (*). Spearman’s correlations between ages are provided for temporal consistency (*** p< 0.001).
