Is this trial a fit for you?

Likely a 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.

Probably 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.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

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 gone: 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.
