Mean ages provided in the headings.
Homotypic continuity is presented on diagonal (in bold), heterotypic continuity across diagonal.
95% confidence intervals (CIs) are presented in parentheses. CIs not inclusive of zeros indicate significant correlations. Non-overlapping CIs mean significant difference between the values.
Results presented on untransformed variables for comparison with other published samples. The within-time correlations between depression and anxiety subscales are discussed elsewhere (Lau et al. 2007; Waszczuk et al. 2014). The homotypic continuity of anxiety subscales has also previously been reported (Waszczuk et al. 2014).
