rater biases due to global,stable, depressogenic halo effects may influence parents’ ratings of child behavior and parenting practices, suchthat parents with greater depressive symptoms may similarly endorse poorer parenting practices and greater child externalizing problems. Indeed, significant relations were observed between parents’ depression/anxiety symptoms and parent-rated child externalizing behaviors, although these relations were of small magnitude (r = .15). However, our finding that parental ADHD symptoms also show relations to PCEs, parenting behaviors, and child externalizing problems sheds doubt on this possibility. In addition, the inclusion of teacher ratings in the composite score for externalizing behavior reduces the likelihood that mono-method bias, secondary to parental depressive symptoms or otherwise, accounts for the present findings.
