Abstract

Background

Aggression is a transdiagnostic indicator of risk and represents one of the most common reasons children are referred for mental health treatment. Theory and research highlight the impact of maternal invalidation on child aggression and suggest that its influence may vary based on differences in child physiological reactivity. Moreover, the interaction between these risk factors may be particularly pronounced among children of mothers with emotion regulation (ER) difficulties. The current study examined the independent and interactive effects of maternal invalidation and child physiological reactivity to frustration on teacher-reported aggression in an at-risk sample of preschool children.

Method

Participants included 77 mothers (Mage = 33.17 years, s.d. = 4.83; 35% racial/ethnic minority) and their children (Mage = 42.48 months; s.d. = 3.78; 56% female; 47% racial/ethnic minority). Groups of mothers with and without clinician-rated ER difficulties reported on maternal invalidation, and child respiratory sinus arrhythmia (RSA) was assessed continuously during a frustration task as an indicator of physiological reactivity. Teachers or daycare providers reported on child aggression.

Results

Results demonstrated positive associations between maternal ER difficulties and both maternal invalidation and child RSA reactivity to frustration. As expected, the interaction between maternal invalidation and child RSA reactivity was significant, such that higher maternal invalidation and greater child RSA reactivity to frustration predicted more aggression in a daycare or preschool setting. Importantly, this effect was demonstrated while controlling for demographic covariates and baseline RSA.

Conclusions

Findings are in line with diathesis–stress and biosocial models of risk and point to multiple targets for prevention and early intervention.

Fig. 1. Multivariate model testing independent and interactive paths from maternal ER difficulties, maternal invalidation, and RSA reactivity to frustration to teacher-reported aggression.Note. Overall model fit was good [χ2(11) = 8.50, p = 0.67; CFI = 1.00; TLI = 1.00; RMSEA < 0.01]. R2(aggressive behavior) = 0.33. Significant associations are bolded and represent standardized effects after accounting for child age, child sex, child minority status, family receipt of public assistance, and child baseline RSA. The direct path between clinician-rated maternal ER difficulties and teacher-reported aggression was also modeled (though not shown above) and was non-significant [β = 0.19 (0.14), p = 0.18]. *p < 0.05; **p < 0.01.

Fig. 2. Maternal invalidation moderates the effect of child RSA reactivity to frustration on teacher-reported aggression. Predictors were mean-centered, and effects are shown at ±1 s.d. above and below the mean on maternal invalidation (mean = 2.39; s.d. = 0.67; range = 1.31–4.61), with higher values reflecting more maternal invalidation, and lower values reflecting less maternal invalidation. Simple slope analyses revealed that child RSA reactivity was related to teacher-reported aggression at higher levels of maternal invalidation (+1 s.d.: b = − 0.57, p = 0.03), but not at lower levels of maternal invalidation (−1 s.d.: b = 0.15, p = 0.29). The overlapping shaded areas represent the point beyond which child RSA reactivity, specifically RSA withdrawal (<−0.36; mean-centered range = −2.93 to 1.87), predicted teacher-reported aggression for preschoolers with higher maternal invalidation (>0.67; mean-centered range = −1.62 to 3.35).
