Improving Parent-Child Interactions to Enhance Child Health (PCIT-Health)

Improving Parent-Child Interactions to Prevent Child Obesity in Early Childhood

Childhood obesity is a formidable public health issue in the United States, disproportionately affecting children from lower socioeconomic status households. Onset of obesity predicts cardiometabolic risks and other health problems in adolescence and into adulthood; thus, effective and early prevention is critical. Healthy parenting may play a pivotal role in preventing early childhood obesity. Warm, responsive, and consistent parenting is associated with the development of child self-regulation as well as healthy eating and physical activity practices, and thus may be protective against obesity risk. Targeting the parent-child relationship may be especially important when facilitating behavior change in parents who have ongoing stressors (e.g., low-income families). The proposed study aims to test an adaptation of Parent-Child Interaction Therapy (PCIT), an innovative parent management program that improves the parent-child relationship and enhances general parenting skills through the use of therapeutic in vivo coaching. Our adapted version, PCIT-Health, is a selective-prevention intervention that includes content specific to improving parent-child interactions and parenting in obesity-salient contexts, such as mealtime and child screen time. This project will elucidate novel approaches to, and novel targets of, early childhood obesity prevention and will provide data critical to test PCIT-Health in a large-scale randomized controlled trial. Parent-child dyads will be randomly assigned to PCIT-Health or a waitlist control in order to accomplish the following aims: AIM 1: To assess the acceptability and feasibility of the PCIT-Health delivery and assessment methods in low-income parents of overweight young children ages 3 to 6 years. AIM 2: To test the preliminary efficacy and estimate the effect size of PCIT-Health on changes in child BMI z-score (primary outcome) from baseline to (1) intervention completion and (2) 6-month post-intervention. AIM 3: To explore the effect of PCIT-Health on the following secondary outcomes: (1) parent-child relationship quality, (2) parent behavior management skills, (3) child self-regulation, (4) child eating behaviors, (5) child physical activity, and (6) child screen media use.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Child Body Mass Index (BMI) Percentile	Change in child BMI percentile will be calculated using standardized anthropometric measurement (height and weight) procedure	Pre-intervention (T1), post-intervention (T2;4 months after pre-intervention), and six-month follow-up (T3;10 months after pre-intervention)
Change in Child Body Mass Index (BMI) Z-score	Change in child BMI z-score will be calculated using standardized anthropometric measurement (height and weight) procedure. The z-score is a standard deviation away from the mean, based on the CDC growth charts. Higher z-scores indicate greater weight status. A Z-score of 0 equals the population mean, based on age and sex.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Child Self-regulation (Parent Report)	Emotion Regulation (ER) Checklist, higher scores = greater regulation (better outcome). Mean calculation for total score, with Min=1 to Max=4	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Child Screen Time	Parent report of weekly amount of time child spends viewing/using screen media. Scores range from 0-168, with total scores reflecting sum of daily screen time across multiple types of screen media. Higher scores = more screen time.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Child Physical Activity	Measured by Actigraph accelerometer to assess sedentary, moderate, moderate-to-vigorous, and vigorous physical activity (MVPA)	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Child Sleep (Parent Report)	Measured by parent report of bedtime, wake time, and naps.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Child Sleep (Via Actigraphy)	Measured by Actigraph accelerometer.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Child Problematic Media Use	Measured by the parent-report via Problematic Media Use Measure (Domoff et al., 2019). Higher scores = greater problematic media use. Total scores = mean of items; Min = 1 to Max = 5.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Parent-child Relationship Quality (Observed)	Dyadic Parent-Child Interaction Coding System-IV (DPICS-IV) will be used. The DPICS provides a reliable measure of parent-child relationship quality (e.g., parents' child-centered skills, parent and child positive and negative physical and verbal interactions) and parent behavior management skills (e.g., use of contingent reinforcement, effective discipline, child compliance). This outcome reflects behavioral observation of parents' child-centered skills ("DO" skills) during child led play. This is a count variable that can range from 0 displayed skills (min) with no determined maximum. Higher numbers = more skills (better outcome).	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Parent-child Relationship Quality (Parent Report)	Scores on the Parent-child Dysfunctional Interaction (PCDI) subscale of the Parenting Stress Index will be used as the parent-report of parent-child relationship quality. Values range from 12 to 60, with higher scores indicating greater dysfunction in (poorer quality of) the parent-child relationship.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Pressure to Eat (Parent-report)	Scores on the Child Feeding Questionnaire (CFQ)- Pressure to Eat subscale will be calculated. This subscale score is a mean, with minimum of 1 and maximum of 5 (higher scores = more pressure to eat, a worse outcome).	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Restriction (Parent-report)	Scores on the Child Feeding Questionnaire (CFQ)-Restriction subscale will be calculated. A mean is calculated for this subscale (min = 1 to max = 5). Higher scores = greater restriction of food (poorer outcome).	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Emotional Feeding (Parent-report)	Child Feeding Questionnaire (CFQ)- Emotional Feeding subscale will be calculated with a mean of responses to items. Min = 1 to max = 5. Higher scores reflect worse outcome.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Instrumental Feeding (Parent-report)	Scores on the Parental Feeding Questionnaire (PFQ)- Instrumental Feeding subscale will be calculated. Mean calculation of responses, with scores ranging from 1 (min) to 5 (max). Higher scores reflect poorer outcome.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Active Mediation of Television (Parent-report)	Scores on the Instructive Mediation subscale of the Parental Mediation Scale (Valkenburg et al., 1999) will be calculated via sum score of 5 items. Min = 5, max = 20, higher scores = better outcome.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Restrictive Mediation of Television (Parent-report)	Scores on the Restrictive Mediation subscale of the Parental Mediation Scale (Valkenburg et al., 1999) will be calculated via sum score of 5 items. Min = 5, max = 20, higher scores = better outcome.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Social Coviewing of Television (Parent-report)	Scores on the Social Coviewing subscale of the Parental Mediation Scale (Valkenburg et al., 1999) will be calculated via sum score of 5 items. Min = 5, max = 20, higher scores = better outcome.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Location/Quantity of Screen Media in the Home (Parent-report)	Parents will report on the location/quantity of screen media in home and child's bedroom.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Media Parenting Practices (Observed)	Family mealtime observations will be coded for presence and use of screen media (TV, mobile device present, other media present). Coding of the observed behavior is as follows: TV on = 1 if TV is on during mealtime, TV on = 0 if TV is off during mealtime, lower values = better outcomes. Mobile device present = 1 if a mobile device is present, 0 if no mobile device is present, with lower values= better outcomes. Other media present = 1 if other screens are present, 0 if no other screens are present (lower values=better outcomes).	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Parent Feeding Practices (Observed)	Family mealtime observations will be coded using a modified version of the Mealtime Interaction Coding System. Aspects of task accomplishment (TA) and behavior control BC) were coded. Scores could range from 1 (min) to 3 (max), with higher scores = better outcomes.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Child Disruptive Behaviors (Parent Report)	Eyberg Child Behavior Inventory (ECBI); intensity t-score. Higher t-scores indicate poorer outcomes (i.e., greater intensity of behavior problems). T-scores have a mean of 50 (SD = 10). T-scores of 60 or higher indicate clinical significance.	Pre-intervention (T1), post-intervention (T2; 4 months after pre-intervention), and six-month follow-up (T3; 10 months after pre-intervention)
Child Psychological Functioning (Parent Report)	Behavior Assessment System for Children (BASC-3); internalizing symptoms t-score (lower scores better outcome) and adaptive skills t-score (higher scores better outcome).
