Infant attachment securityb	0.05	-0.40	1, 53	ns
Maternal disrupted communication:
Affective communication errors	0.04	0.68	1, 53	ns
Role confusion	0.08	-0.54	1, 53	ns
Disorientation	0.05	0.35	1, 53	ns

Childhood abuse to age 18
Severity of abuse	0.29	2.31*	1, 53	0.02

Note. N = 56. Gender and adolescent depression controlled in all analyses; gender t-ratio = 0.68, ns; depression t-ratio = 2.62, P < 0.05.

^aStatistics for all seven infancy variables entered on one step, F(7, 46) = 4 .18^**, P = 0.007.

^bThe two-category contrast, disorganized vs not disorganized, was also non-significant, t = 0.46, ns.

^*P < 0.05.

^**P < 0.01.

^***P < 0.001.
