Early Life Stress and Child Temperament Style as Predictors of Childhood Anxiety and Depressive Symptoms: Findings from the Longitudinal Study of Australian Children

Table 4

Odds ratios for anxiety and depressive symptoms at age 4 years attributable to person-environment interaction between early life stress and avoidant temperament style.

		Anxiety and depressive symptoms at 4 years
Infant avoidance	Stress exposure		Noncase	Case	OR^†	95% CI^†		PPV	AR%
