Researchers have argued for more dynamic and contextually relevant measures of regulatory processes in interpersonal interactions. In response, we introduce and examine the effectiveness of a new task, the Parent-Child Challenge Task, designed to assess the self-regulation and coregulation of affect, goal-directed behavior, and physiology in parents and their preschoolers in response to an experimental perturbation. Concurrent and predictive validity was examined via relations with children’s externalizing behaviors. Mothers used only their words to guide their 3-year-old children to complete increasingly difficult puzzles in order to win a prize (N = 96). A challenge condition was initiated mid-way through the task with a newly introduced time limit. The challenge produced decreases in parental teaching and dyadic behavioral variability and increases in child negative affect and dyadic affective variability, measured by dynamic systems-based methods. Children rated lower on externalizing showed respiratory sinus arrhythmia (RSA) suppression in response to challenge, whereas those rated higher on externalizing showed RSA augmentation. Additionally, select task changes in affect, behavior, and physiology predicted teacher-rated externalizing behaviors four months later. Findings indicate the Parent-Child Challenge Task was effective in producing regulatory changes and suggest its utility in assessing biobehavioral self-regulation and coregulation in parents and their preschoolers.

AIM To test the effect of child, family, and environmental factors on young children’s participation in home-based activities. METHOD Caregivers of young children were recruited using convenience and snowball sampling. Participants were 395 caregivers of children aged from 1 month to 5 years and 11 months. Demographic items and the home section of the Young Children’s Participation and Environment Measure were administered online, followed by completion of the daily activities, mobility, and social/cognitive domains of the Pediatric Evaluation of Disability Inventory Computer Adaptive Test by telephone interview. RESULTS A structural equation model fitted the data well (comparative fit index=0.91) and explained 31.2% of the variance in perceived environmental support and 42.5% of the variance in home involvement. Functional limitations and performance had an indirect effect on young children’s participation through their effect on perceived environmental support. Specifically, fewer functional limitations and higher task performance were associated with greater environmental support, which in turn predicted higher levels of home involvement. INTERPRETATION Results suggest the importance of a young child’s functional abilities and task performance on caregiver perceptions of environmental support at home, and the impact of environmental support on a child’s participation in home-based activities during the early childhood period. Results warrant replication with more diverse samples to evaluate model generalizability.

Lower levels of parent–child affective flexibility indicate risk for children’s problem outcomes. This short-term longitudinal study examined whether maternal depressive symptoms were related to lower levels of dyadic affective flexibility and positive affective content in mother–child problem-solving interactions at age 3.5 years (N=100) and whether these maternal and dyadic factors predicted child emotional negativity and behaviour problems at a 4-month follow-up. Dyadic flexibility and positive affect were measured using dynamic systems-based modelling of second-by-second affective patterns during a mother–child problem-solving task. Results showed that higher levels of maternal depressive symptoms were related to lower levels of dyadic affective flexibility, which predicted children’s higher levels of negativity and behaviour problems as rated by teachers. Mothers’ ratings of child negativity and behaviour problems were predicted by their own depressive symptoms and individual child factors, but not by dyadic flexibility. There were no effects of dyadic positive affect. Findings highlight the importance of studying patterns in real-time dyadic parent–child interactions as potential mechanisms of risk in developmental psychopathology.

Predictable patterns in early parent-child interactions may help lay the foundation for how children learn to self-regulate. The present study examined contingencies between maternal teaching and directives and child compliance in mother-child problem-solving interactions at age 3.5 and whether they predicted children’s behavioral regulation and dysregulation (inhibitory control and externalizing behaviors) as rated by mothers, fathers, and teachers at a 4-month follow-up (N = 100). The predictive utility of mother- and child-initiated contingencies was also compared to that of frequencies of individual mother and child behaviors. Structural equation models revealed that a higher probability that maternal directives were followed by child compliance predicted better child behavioral regulation, whereas the reverse pattern and the overall frequency of maternal directives did not. For teaching, stronger mother- and child-initiated contingencies and the overall frequency of maternal teaching all showed evidence for predicting better behavioral regulation. Findings depended on which caregiver was rating child outcomes. We conclude that dyadic measures are useful for understanding how parent-child interactions impact children’s burgeoning regulatory abilities in early childhood.
