Child maltreatment (CM) lies on an extreme end of the continuum of parenting-at-risk, and while CM has been linked with a variety of behavioral indicators of dysregulation in children, less is known about how physiological markers of regulatory capacity contribute to this association. The present study examined patterns of mother and child physiological regulation and their relations with observed differences in parenting processes during a structured interaction. Abusing, neglecting, and non-CM mothers and their 3- to 5-year-old children completed a resting baseline and moderately challenging joint task. The structural analysis of social behavior was used to code mother–child interactions while simultaneous measures of respiratory sinus arrhythmia were obtained. Results indicated that physically abusive mothers were more likely to react to children’s positive bids for autonomy with strict and hostile control, than either neglecting or non-CM mothers. CM exposure and quality of maternal responding to children’s autonomous bids were uniquely associated with lower parasympathetic tone in children. Results provide evidence of neurodevelopmental associations between early CM exposure, the immediate interactive context of parenting, and children’s autonomic physiology.

The present study assessed behavioral distress during noninvasive outpatient procedures in children ages 4-10 years using a multimethod approach. Factors hypothesized to exacerbate children's distress included parents' and children's attitudes toward healthcare, children's knowledge of medical settings, and parental anxiety. A total of 53 parent-child dyads were recruited from outpatient clinics, with procedural distress assessed via child report, parent report, and direct observation. Some differences emerged depending on the method used to gauge distress. Children's healthcare attitudes and knowledge were associated with observed and child-reported distress, but parent's personal anxiety was associated only with their own perceptions of children's procedural distress. Parents' attitudes toward healthcare were associated with their anxiety but not with children's behavioral distress or healthcare attitudes. Findings are discussed in terms of more consistent findings regarding children's healthcare knowledge and attitudes versus the potential need for additional research on more divergent findings regarding parents' anxiety and healthcare attitudes.
