Detailed Description
Objectives and Background
The purpose of this study is to determine whether Duet 2.0- a light-touch, public health model of remote intervention delivery 1) increases caregiver knowledge about children's language development, 2) improves caregiver-child language interaction quantity and quality, and 3) enhances children's language skills. It is hypothesized that dyads who receive the Duet 2.0 intervention will make greater gains in knowledge of child development, early interaction quality, and child language skills than the delayed-access control group. Secondary analyses will be conducted to examine if and how parent (e.g., self-efficacy) and child (e.g., child language abilities) characteristics relate to each other, baseline measures, and treatment outcomes.
Early language skills are fundamental to language, cognitive, and socioemotional development and are the single best predictors of later academic success. Caregiver-child language interactions in the first three years of life not only predict early language development, but also influence school readiness skills and academic achievement. High-quality early language interactions are characterized by rich and diverse vocabulary, responsive talk (i.e., language following the child's attention), decontextualized language (e.g., language beyond the here and now context, "Remember we went to a party last night"), communication foundation (e.g., use of verbal and gestural symbols, engaging in back-and-forth conversations), and question use. In fact, early reading outcomes are particularly contingent on strong language skills that go beyond and accompany strong decoding skills.
Despite the importance of these factors, there are large disparities in the frequency and quality of children's early language interactions. Although there is great within-group variability, children from low-income families on average have fewer and lower-quality language experiences than their middle- or high-income peers. Early disparities in language experiences can lead to gaps in language skills and academic achievement that persist into adulthood.
Duet 2.0 will adopt an innovative and scalable approach-remote delivery and coaching. This design reflects arguably the strongest evidence for successful intervention. Remote coaching and telehealth are becoming accepted models for public health intervention in domains like nutrition, fitness, heart health, and diabetes. There is also growing support for remote delivery parent and teacher training programs. For instance, remote coaching has effectively improved Head Start teachers' language and literacy practices. This intervention model has also been used successfully to promote mental health in parents of infants, train parents in domains such as child socioemotional development, and support language and communication in young children with autism.
With the support of the William Penn Foundation and the Bezos Family Foundation, the PIs spent three years designing and piloting a caregiver- implemented early language intervention program-The Duet Project: Early Engagement, Future Success. Using community-based participatory research (CBPR) framework with partners at the Maternity Care Coalition (MCC), the PIs created Duet training materials that are evidence-based and culturally sensitive.
Pilot work with Duet yielded promising findings despite low sample sizes. These preliminary results support the efficacy of the Duet modules. Duet participants included some Spanish speakers; however, all participants had to be able to receive services in English. This significantly limited recruitment-nearly 25% of infants and toddlers in Philadelphia are of Latino/Hispanic origin. Furthermore, the percent of Hispanic/Latino people living in poverty is disproportionately high-they make up 21% of the population living in poverty but only 14.4% of the total population.
Translating the Duet modules into Spanish and developing a more efficient delivery system will maximize their scalability and positive impact on low-SES families. Establishing an efficient communication foundation, will enhance language learning and literacy development with the goal of narrowing the achievement gap in future generations. Given the undeniably powerful link between early language competencies and later literacy skills, this intervention has the potential to have long-lasting and widespread benefits both at local and national levels.
Duet 2.0 Intervention and Data Collection
Prospective research participants will be identified and recruited through the Department of Pediatrics at Temple University Health System(TUHS) and possibly by sharing recruitment materials with local community organizations (e.g., Early Head Start centers). Participants will be recruited and screened. If they meet study requirements during screening, they will then be consented and enrolled. Families who are randomly selected into the intervention group will complete the modules at home on their own time and receive remote coaching from an interventionist or coach (terms used interchangeably). Families in the delayed-access control group will receive access to the modules at the end of the study, but will still complete data-collection sessions. Approximately once a week after enrollment, Interventionists will support the intervention-group families remotely in comprehending and implementing what they have learned from the modules. Interventionists may also be involved in remote data collection. All participants will be scheduled for follow-up data collection sessions via phone or video conference.

Intervention / Treatment |
---|---|
Experimental: Intervention
The Duet 2.0 intervention is comprised of six training modules, which include behavioral strategies, real-life and animated examples of high-quality early language interactions, and interactive scenarios.
Modules were translated into Spanish.
Participants will watch one Duet intervention module a week and have up to 3 months to complete all 6 modules.
As intervention families review the modules on their own time at home, they will receive remote coaching from an assigned interventionist and weekly module-specific fidelity/comprehension questions.
Interventionists will check-in weekly via phone or video (~30-60 minutes), whichever is more convenient for the family.
During the check-in, interventionists will do teach-back about the module, guide the family on how to incorporate the strategies into their daily lives, and provide feedback.
Intervention participants will be scheduled for follow-up data collection at 3 months, 6 months, and pending funding, 1-year after baseline.
|
The Duet 2.0 intervention modules promote the following guiding principles that help build effective communication.
Below are the 5 principles covered in the six Duet modules: 1) General Awareness: Awareness and knowledge of child development 2) Creating Opportunities: Opportunities for communication during everyday activities 3) Conversational Duets: Rhythmic and reciprocal early language interactions 4) Scaffolding: Providing just enough help to support child independence 5) Harmonizing: Using the strategies together.
These modules, which include behavioral strategies, real-life and animated examples of high-quality early language interactions, and interactive scenarios.
The modules were informed and narrated by community members and carefully designed to address specific needs of high-risk communities.
The modules have also been translated into Spanish, making sure to encompass specific cultural and dialect needs.
Translation accuracy was verified by a qualified Spanish translator.
|
No Intervention: Delayed Access
Participants who are in the delayed access control group will not have to complete the modules and will be scheduled for a 3-month, 6-month, and pending funding, a 1-year follow-up calls.
They will have delayed access to the modules, which means that they will receive access to the module videos at their 6-month study session and will be offered the opportunity to contact the research team with any questions.

Measure Description |
Time Frame |
---|---|---|
Change in Quality of Caregiver-Child Language Interaction
Time Frame: Baseline, 3-month follow-up, and 6-month follow-up
|
To assess the quality of caregiver-child interactions, caregivers and participating children will be filmed or film themselves for a total of 10-15 minutes, at baseline, 3-month, and 6-month follow-up sessions.
We will calculate the number of conversational turns.
|
Baseline, 3-month follow-up, and 6-month follow-up
|
Change in Parent/Provider Expectations and Knowledge
Time Frame: Baseline, 3-month follow-up, and 6-month follow-up
|
Caregiver's knowledge of child development will be assessed at baseline and post intervention.
The Parent/Provider Expectations and Knowledge-II (SPEAK-II) is a well-validated measure used in similar research.
Higher scores on the SPEAK-II indicate more knowledge about early language development.
