Partial correlations between (A) secure attachment scores at 42 m and friendship measures at age 16 across groups and within-group.

All analyses adjust for sex differences:

n in secure scores=115 (42 CAUG, 47 FCG, 26 NIG), n in age of placement within the FCG= 46.

Analyses on friend and self rated FQ and observed behaviors exclude those paired with strangers and acquaintances and adjust for whether the peer had a history of institutionalization:

n with secure scores= 93 (33 CAUG, 34 FCG, 26 NIG), n with age of placement within the FCG= 31

n with secure scores=97 (34 CAUG, 37 FCG, 26 NIG), n with age of placement within the FCG=35.
