Note. N = 56. Gender and adolescent depression controlled in all analyses; gender X² = 0.23, ns; depression X² = 1.37, ns.

^aStatistics for all seven infancy variables entered on one step X²(7) = 21.55, P = 0.03.

^bThe two-category contrast, disorganized vs not disorganized, was also marginally significant, Wald = 3.66 P = 0.06.

^xP < 0.10.

^*P < 0.05.

^**P < 0.01.
