For intervention condition, attachment-based intervention = 1 (n = 34), control intervention = 0 (n = 32); for attachment disorganization, organized attachment = 0 (n = 44), disorganized attachment = 1 (n = 20). All values shown are Pearson correlations of continuous variables, except those with intervention status and attachment disorganization which are Spearman’s rank correlations. Descriptive statistics for cortisol are log10 transformed values due to positive skew.
