Parent-Child Interaction Therapy Supports Healthy Eating Behavior in Child Welfare-Involved Children

Impact of parent child interaction therapy on child eating behaviors

BACKGROUND

Picky eating commonly co-occurs with disruptive behaviors in young children. While feeding interventions exist, it remains unknown whether unmodified behavioral parent training (BPT) improves maladaptive child eating. As coercive feeding practices may exacerbate picky eating, BPT could ameliorate associated behaviors by increasing authoritative parenting.

METHODS

Caregiver-child dyads (N = 194, ages 2-8) received 18 weeks of Parent-Child Interaction Therapy (PCIT). Caregivers completed the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) at pre-, mid-, and post-treatment. The BPFAS overall picky eating frequency and number of problems was examined, as well as the subscale of mealtime misbehaviors, and overall caregiver feeding practices.

RESULTS

From pre-to post-treatment, reductions occurred in frequency/problems scales across overall BPFAS child behaviors. Mealtime misbehaviors significantly declined at all checkpoints - early skill acquisition may drive this early change, whereas changes in frequency/problem scales occurred after mid-treatment, suggesting later skill acquisition may be driving these changes. On the coercive caregiver feeding subscale, multivariate regression identified a significant race by time interaction (p = .02) - multiracial caregivers improved while others showed no difference.

CONCLUSION

Standard PCIT, not adapted for feeding concerns, decreased maladaptive child eating behaviors across all caregivers and coercive feeding practices in multiracial caregivers. Authoritative parenting principles may generalize to eating contexts for certain cultural groups. PCIT shows promise as an early upstream intervention potentially changing trajectories without needed feeding content modifications. Assessment of long-term maintenance is warranted. Coupling with nutrition education could optimize impact.

Investigating mother-child inter-brain synchrony in a naturalistic paradigm: A functional near infrared spectroscopy (fNIRS) hyperscanning study

Successful social interactions between mothers and children are hypothesised to play a significant role in a child's social, cognitive and language development. Earlier research has confirmed, through structured experimental paradigms, that these interactions could be underpinned by coordinated neural activity. Nevertheless, the extent of neural synchrony during real-life, ecologically valid interactions between mothers and their children remains largely unexplored. In this study, we investigated mother-child inter-brain synchrony using a naturalistic free-play paradigm. We also examined the relationship between neural synchrony, verbal communication patterns and personality traits to further understand the underpinnings of brain synchrony. Twelve children aged between 3 and 5 years old and their mothers participated in this study. Neural synchrony in mother-child dyads were measured bilaterally over frontal and temporal areas using functional Near Infra-red Spectroscopy (fNIRS) whilst the dyads were asked to play with child-friendly toys together (interactive condition) and separately (independent condition). Communication patterns were captured via video recordings and conversational turns were coded. Compared to the independent condition, mother-child dyads showed increased neural synchrony in the interactive condition across the prefrontal cortex and temporo-parietal junction. There was no significant relationship found between neural synchrony and turn-taking and between neural synchrony and the personality traits of each member of the dyad. Overall, we demonstrate the feasibility of measuring inter-brain synchrony between mothers and children in a naturalistic environment. These findings can inform future study designs to assess inter-brain synchrony between parents and pre-lingual children and/or children with communication needs.
