- Registration Number
- NCT06562439
- Lead Sponsor
- Washington University School of Medicine
- Brief Summary
Sickle cell disease affects 100,000 people and 2,000 newborns each year; 50% of these children have a developmental deficit (\>2 SD) before the age of 3. Early identification of developmental deficit supports timely intervention, but children with sickle cell disease are grossly underdiagnosed and undertreated. The goal of the proposed study is to determine the incidence and severity of developmental deficit at 9, 18 and 30 months of age among children with sickle cell disease and test a 12-month, home-based caregiver intervention with this disproportionately affected population.
- Detailed Description
This trial will be conducted in two phases. In Aim 1, the investigators are evaluating the developmental progress of children with and without sickle cell disease (SCD) at 9, 18, and 30 months. The investigators aim to recruit a total of 100 children and their caregivers (SCD = 50, Comparison = 50). Each child/caregiver dyad will be asked to complete 3 evaluation visits where the child's developmental progress will be evaluated and the caregiver will complete surveys related to their child's development, participation, and the caregiver's mental health.
In Aim 2, children with sickle cell disease will be randomized to receive developmental evaluations at 9, 18, and 30 months alone or a 12-month home-based intervention + developmental evaluations. The intervention is called the Sickle Cell Collaboration for Child Development (SCCCD) uses the widely used Parents as Teachers curriculum and is supplemented with specific support for the caregivers related to the child's sickle cell diagnosis. This pilot randomized controlled trial design is designed to (1) examine the potential effects of SCCCD on child development and caregiver well-being compared to the group with no intervention and (2) optimize trial procedures to enhance acceptability and scalability in preparation for a full-scale trial. Data will be collected to explore determinants (facilitators and barriers) affecting participation and outcomes. The investigators will recruit 50 children with sickle cell disease to this aim, with the goal to have 25 children randomized to intervention. Randomization will be completed using a random computer generator that can balance groups based on key factors like age, sex, and area deprivation index (index approximating income and community resources).
Participants randomized to SCCCD (n=25) will be invited to participate in 12 home-based intervention session over the course of 1 year (1 visit monthly) with a trained parent educator. They will complete the visit according to the Parents as Teachers curriculum and will provide additional discussion focused on sickle cell disease and strategies to promote child development. If caregivers are uncomfortable with home-visits, families will have the option to complete intervention visits in our on-site clinic space or in a preferred community location (e.g., public library, child care setting, place of worship). Participants in the developmental evaluation group will complete study visits as described in Aim 1.
The primary outcomes are child development and caregiver acceptability of developmental screening and intervention. The investigators will use implementation strategies guided by our earlier work to optimize the program's feasibility which will be measured by tracking participation and retention rates in each phase of this study. Acceptability will be assessed through interviews and surveys.
Recruitment & Eligibility
- Status
- NOT_YET_RECRUITING
- Sex
- All
- Target Recruitment
- 50
- All sickle cell disease genotypes will be included. Children will be eligible to participate until they reach 31 months of age (1 month over target evaluation).
- Children will be excluded if the child has fragile health, a diagnosis associated with developmental deficit (not sickle cell disease), or the family is not English language proficient -because of limitations in alternative language assessment and intervention delivery.

Group Intervention Description Developmental Screening + Home-Based Intervention Sickle Cell Collaboration for Child Development Participants in this group will complete developmental screening at 9, 18 and 30 months of age and monthly home visits with the family using the Parents as Teachers curriculum.
- Primary Outcome Measures
Name Time Method Bayley Scales of Infant Toddler Development-IV Completed at 9, 18 and 30 months Child participants will complete up to 3 developmental evaluations with a trained evaluator using the Bayley Scales of Infant Toddler Development-IV. The Bayley assesses development in the domains of cognition, fine and gross motor, and expressive and receptive language. Caregiver questionnaires assess adaptive behavior and social emotional development. Scaled scores range from 1-19, where a score of 10 is average and a higher score indicates better outcome.
Ages and Stages Questionnaire-3 Completed at 9, 18 and 30 months Caregivers will complete the Ages and Stages Questionnaire-3, which assesses the caregivers perspective of how their child is meeting developmental milestones in the domains of communication, gross motor, fine motor, personal-social and problem solving. Scores range from 0-60, where a higher score indicates a better outcome.
Behavior Rating Inventory of Executive Function-Preschool 30 months of age The Behavior Rating Inventory of Executive Function-Preschool (BRIEF) evaluates executive functioning of toddlers \>2.5 years. Executive functioning is identified as a high risk domain for deficits among individuals with sickle cell disease. Raw scores are converted to t-scores (mean = 50, SD = 10) and scores above 65 are considered clinically significant.
Infant Toddler Activity Card Sort Completed at 9, 18 and 30 months Caregivers will complete the Infant Toddler Activity Card Sort (ITACS) to determine activities and routines that are presenting performance or participation challenges for families in the context of their everyday lives.
- Secondary Outcome Measures
Name Time Method Fidelity through study completion, an average of 1 year The Comprehensive Intervention Fidelity Guide will be used to evaluate intervention design, training and delivery. This guide specifies the intervention model, the fidelity indices (e.g., participation and retention rates) and compare those to outcome measures.
PROMIS Depression (Caregiver) Completed at child's 9, 18 and 30 month evaluation. The Patient Reported Outcomes Measurement Information Systems (PROMIS) Depression short form is a valid and reliable 8-item tool to screen for depression. Scores range from 8-40, with higher scores indicating more severe depression symptoms.
Acceptability through study completion, an average of 1 year Study visit completion rates and notes from intervention visits will be reviewed. Interviews will be conducted with all participants in the SCCCD intervention, regardless of completion to determine components that contributed to participation or attrition.
