Parenting interventions, particularly those categorized as parent management training (PMT), have a large evidence base supporting their effectiveness with most families who present for treatment of childhood behavior problems. However, data suggest that PMTs are not effective at treating all families who seek services. Parental psychopathology has been identified as one important factor moderating their effectiveness, yet few PMTs pay explicit attention to the role of parental psychopathology in treatment. Given growing support for a transdiagnostic model of psychopathology, which posits that disruptions in emotions and emotion regulation (ER) may underlie various forms of psychopathology, one way to address the impact of parental psychopathology on PMT may be by targeting parental ER. This paper will review the available literature on PMT and parental psychopathology, as well as existing evidence on relations between ER and both parental psychopathology and parenting behaviors. The limited research on PMTs that include explicitly parent-focused components will be reviewed, and suggestions for augmenting existing PMT curricula by including intervention around parental ER will be presented.
