Note: Abbreviations are explained in the first footnote to table 4. Bivariate genetic (Bivariate a 2), common environment (Bivariate c 2), and unique environment (Bivariate e 2) estimated indicate the proportion of phenotypic correlations explained by genetics, common, and unique environments, respectively. Bivariate genetic (r a), common environment (r c), and unique environment (r e) correlations indicate the genetic and environmental overlap between psychotic experiences and bullying victimization. 95% confidence intervals in parentheses.
