Does poor vagal tone exacerbate child maladjustment in the context of parental problem drinking? A longitudinal examination.
Children's vagal tone was examined as a vulnerability factor in the longitudinal relation between mothers' (MPD) and fathers' (FPD) problem drinking and children's adjustment. At T1, MPD and FPD were examined, and children's vagal tone was assessed. Two years following initial participation, child adjustment problems were evaluated. A lower level of vagal tone was a vulnerability factor for internalizing problems associated with MPD and FPD and for externalizing difficulties associated with MPD. In the context of a higher level of MPD or FPD, a lower level of vagal tone was a vulnerability factor for increases in externalizing problems over time. Results are supportive of the importance of biopsychosocial perspectives in which child characteristics interact with family risk to predict psychopathology.
