Results reported above represent those examining both cross-sectional and prospective correlations, in line with moderation analyses reported in the text. The first portion of the table presents overall r-values within each sub-category of non-continuous moderators.

Supplemental materials report effects codes that explicitly compare the size of these r-values across sub-categories, and further subdivide results according to cross-sectional and prospective correlations. “N Effect Sizes”=the number of correlations within each subcategory; CI=confidence interval; τ =unexplained variance; SE=standard error. AAI=Adult Attachment Interview; AAS=Adult Attachment Scale; IPPA=Inventory of Parent and Peer Attachment.
