ABSTRACT
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.
