Helping toddlers of caregivers with substance use disorders build language skills with group and individualized parenting supports

Evidence-based Intervention Enhancements to Reduce Language Delays and Disorders Among Children of Parents With Substance Use Disorders

NA · University of Oregon · NCT07529327

This project will test whether adding coaching and one-on-one lessons to a group parenting program helps toddlers (12–42 months) of caregivers with substance use disorders develop better language skills.

What this trial studies

Researchers will randomize 244 parent-child pairs into a 2x2 factorial design where everyone receives the Learn and Play Every Day group-based parent-implemented naturalistic communication intervention and some receive additional parental coaching, individualized lessons, both, or neither. The additional coaching and individualized lessons are delivered via telehealth, and randomization is stratified by the parent's primary language (English vs. Spanish). Recruitment occurs through community agencies serving adults with substance use disorders, and interventionists delivering different components are masked to the other components to limit bias. The team will measure child language outcomes, parent responsivity, and other related measures to compare the added benefit of the extra supports.

Who should consider this trial

Good fit: Caregivers aged 18 or older with a lifetime history of SUD treatment or active use in the past year who care for a child 12–42 months old with limited expressive vocabulary (under ~150 words and not regularly combining three or more words), who can speak English or Spanish and are willing to attend weekly in-person groups and any assigned Zoom sessions.

Not a fit: Children who are already combining three or more words regularly, have expressive vocabularies above the study threshold, or families unable to attend weekly group sessions or telehealth visits likely will not benefit from this program.

Why it matters

Potential benefit: If successful, the combined approach could reduce early language delays and boost vocabulary growth for young children of caregivers with substance use disorders.

How similar studies have performed: Parent-implemented naturalistic communication interventions have shown improvements in early language and vocabulary in prior research, though their specific deployment for children of caregivers with substance use disorders has been less studied.
