Parent Acceptance and Commitment Therapy (PACT) for Parents of Children With Pediatric Feeding Disorder

The goal of this study is to advance the science of a brief parent mental health intervention for parents of children with pediatric feeding disorder using Parent Acceptance and Commitment Therapy (PACT-F). The ultimate goal of this research is to improve parent mental health and child health and feeding outcomes through a parent-focused behavioral intervention.

PACT-F is a 2-session acceptance and commitment therapy (ACT) intervention guided by Brown and Whittingham's ACT intervention for parents of children with neurodevelopmental conditions. Intervention content is based on principles of ACT, an evidence-based treatment for adult mental health problems. The intervention content is therefore broadly applicable to all parents but was specifically tailored for the needs of parents of children with neurodevelopmental conditions. In study phase 1 of this award, the investigators adapted parent ACT for parents of children with pediatric feeding disorder (PACT-F) with consultation from 2 parents of children with pediatric feeding disorder and 2 experts in parent ACT. The investigators now have a complete treatment package that has been tailored for parents of children with pediatric feeding disorder and is ready to be piloted.

Thus, in this study the investigators will conduct a feasibility and proof-of-concept pilot of a 2-session parent-focused ACT intervention tailored to meet the needs of parents of children with pediatric feeding disorder (PACT-F). The goal of this pilot is to determine factors that impact the success of recruitment, retention, assessment, and treatment delivery for the PACT-F clinical trial and to test the intervention's proof of concept (i.e., does it show a clinically meaningful signal of change in parent mental health). This study will be conducted at a single site (Children's Mercy Hospital). The investigators will pilot the clinical trial procedures and monitor feasibility success, and factors that may impact feasibility success. Participants who meet inclusion criteria will be randomized to either PACT-F or an attention control (control) condition. Participants will be blind to treatment condition (single blind study). The aim of the feasibility analyses is to evaluate factors critical to success, rather than evaluating whether the intervention is "feasible or not feasible". The aim of the proof-of-concept analyses is to determine if this intervention has promise and warrants a larger efficacy trial.

Parents randomized to PACT-F will complete two 90-minute PACT-F sessions individually with a study interventionist, 2 weeks apart. Parents randomized to the control group will complete two 90-minute sessions individually with a study interventionist, 2-weeks apart (focused on nutrition education). The control intervention will be parallel to the ACT intervention in all ways, including interactive components and the face-to-face time with health professionals (interventionists). The control condition intervention has already been developed by Dr. Davis's research team and covers a range of nutrition and healthy lifestyle topics including the United States Department of Agriculture's (USDA) MyPlate. An attention control condition was selected to mimic the interpersonal benefits that may come from meeting individually with a caring professional. The control condition intervention content (healthy lifestyles) was specifically chosen as it most closely reflects the types of information that parents would learn from healthcare professionals about the type of nutrition that their child needs. However, this type of intervention should not impact parent mental health.

Interventionists for both conditions will be individuals with at least master's degree training in mental health or a related field. The interventions will take via tele-video conferencing to allow participants to participate from home without needing transportation to and from the hospital. Both arms of the intervention will be manualized and interventionists in both arms will be trained using didactics and role playing with the Principle Investigator(PI). Intervention fidelity will be monitored by audio/video recording all sessions. The PI (Dr. Bakula) will review recordings each week and conduct separate 1-hour weekly supervision of study interventionists for each arm of the study (PACT-F \& control).

Strategies will be used to promote fidelity in line with recommendations from the NIH Behavior Change Consortium. A fidelity checklist will be developed in line with adaptations to the intervention and will be piloted with study interventionists. The fidelity checklist will be refined during research team meetings. The fidelity checklist will be reviewed by the PI during supervision.

Hypothesis testing: The investigators will test the hypothesis that PACT-F results in clinically meaningful change using the Reliable Change Index (RCI; success defined as RCI > 1.96). The investigators anticipate that these procedures will be feasible, with feasibility success defined as recruitment rate above 60%, and retention, assessment completion, and intervention completion rate above 80%. Mixed methods data collection will identify factors that impact 1) recruitment rate (qualitative interviews, % meeting inclusion criteria, # of contact attempts), 2) retention rates (qualitative interviews, baseline characteristics; treatment group), 3) assessment completion rate (qualitative interviews, measure type), and 4) treatment completion rate (qualitative interviews, scheduling, treatment location).

The proposed study is an important first step towards developing an evidence-based treatment that can be used with parents of children with pediatric feeding disorder. This intervention has the potential to improve parent mental health, as well as child health, and therefore has the potential to have broad public health impact.
