Multiple Linear Regression Results for Alternate Caregiver-Rated PDD^a,^b

Independent Variable	β	Unstandardized B Coefficient	95% CI for B	P Value
Maternal epilepsy	−0.044	−0.028	−0.134 to 0.078	.607
No. of children in the home	−0.124	−0.015	−0.036 to 0.005	.146
Prenatal SRI (drug weeks)	0.171	0.001	< 0.001 to 0.002	.047

^aPDD subscale score reflects a T score with a mean of 50 and an SD of 10. Bolded values show significance at P < .05, t = 2.01.

^bThe following variables were tested as covariates and were not significantly associated with the PDD subscale: child's age; child's gender; mother's age; mother's marital status; number of adults in the home; mother's work status; average hours mother worked per week; whether the child attended a structured early learning program; maternal depressive symptoms (BDI) at preschool visit; area under the curve measures for prenatal exposure to marijuana, alcohol, caffeine, tobacco, bupropion, mood stabilizers, anxiolytics, and hypnotics; postpartum exposure to SRIs, bupropion, mood stabilizers, anxiolytics, and hypnotics; birth weight, Apgar scores; gestational age; head circumference; delivery method; number of delivery complications; number of pregnancy complications; and maternal prenatal measures of depressive symptoms, mood episodes, and global assessment of functioning.

Abbreviations: PDD = Pervasive Developmental Disorder subscale of the Child Behavior Checklist, SRI = serotonin reuptake inhibitor.
