“…These findings extend previous meta-analytic results that indicate a field-specific small to medium effect size (Schuengel et al, 2021) when examining the association between disorganized attachment to one parent and externalizing behavioral problems (d = 0.34, 95% CI: 0.18, 0.50; Fearon et al, 2010). Moreover, the findings regarding the null effect of organized/disorganized attachment networks on internalizing behavioral problems are in line with previous meta-analytic results that indicated that disorganized attachment to a single parent was non-significantly associated with internalizing behavioral problems (d = 0.08, 95% CI = −0.06, 0.22, Groh et al, 2012; d = 0.12, 95% CI = −0.02, 0.23, Madigan et al, 2013).…”
