EMT en Español Para Autismo: A Collaborative Communication Intervention Approach and Single Case Design Pilot Study.

The primary purpose of the current pilot study was to test the effects of an adapted and collaborative intervention model with a systematic teaching approach on Latina Spanish-speaking caregivers' use of EMT en Español Para Autismo strategies with their young children on the autism spectrum. A multiple baseline across behaviors single case design was replicated across two dyads. A series of family interviews and a direct therapist-child intervention phase supported individualization of the intervention. Families were provided speech generating devices as part of their children's intervention protocol. Caregivers were taught to use EMT en Español Para Autismo strategies with aided language input. Strategies included contingent target-level and proximal target-level language modeling, linguistic expansions, and communication elicitations. Secondary variables measured included generalization of strategy use to unsupported interactions and at a 2-month follow-up, child communication outcomes, and social validity. There was a strong functional relation for one dyad between the adapted and collaborative intervention and caregiver use of EMT strategies. The functional relation was weakened by behavioral covariation for the other dyad. Children increased the quantity and diversity of their communication during the study. Caregivers generalized their use of most EMT strategies and reported most aspects of the approach to be socially valid. The current study provides an initial demonstration of an effective model for adaptation and individualization of naturalistic developmental behavioral interventions for Latino Spanish-speaking families with children on the autism spectrum.

Teaching Spanish-Speaking Caregivers to Implement EMT en Español: A Small Randomized Trial.

PURPOSE: The primary purpose of this study was to examine the effects of using the Teach-Model-Coach-Review approach to teach Spanish-speaking caregivers from low-income households to implement EMT en Español with their young children with language delays. A secondary purpose was to explore the effects of the caregiver-implemented intervention on children's vocabulary. A final and more exploratory goal was to gain insight into caregivers' perceptions of the intervention. METHOD: 21 caregiver-child dyads participated in the intent-to-treat randomized control trial. Their children were 30-43 months old with language delays. Dyads were randomly assigned to receive 24 caregiver training sessions delivered at home in Spanish or a wait list control group. Pre, post and 3-month follow assessments included observational measures of caregiver-child interactions and child standardized vocabulary assessments. Caregivers completed surveys rating their perception of the intervention. RESULTS: Caregivers in the intervention group had significantly higher percentages of matched turns, expansions, and targets at post-assessment and of expansions and targets at follow-up compared to the control group. Overall, children in the intervention condition had significantly higher receptive vocabulary scores and performed better than children in the control condition on observational measure of their lexical diversity, with moderate effect sizes for most outcomes. Caregivers perceived the intervention as effective and culturally appropriate. CONCLUSIONS: Teach-Model-Coach-Review is effective in increasing Spanish-speaking caregivers' use of EMT en Español strategies with their young children with language delays. The intervention also appears to be effective for child vocabulary outcomes and acceptable to caregivers.

Teaching Low-Income Spanish-Speaking Caregivers to Implement EMT en Español With Their Young Children With Language Impairment: A Pilot Study.

Purpose: This study examined the effectiveness of teaching low-income Spanish-speaking caregivers of young children with language impairment a naturalistic language intervention, EMT en Español. Method: A single-case, multiple-baseline, across-behaviors design replicated across 3 caregiver-child dyads was used to examine the effects of teaching core EMT en Español strategies. The training program utilized the Teach-Model-Coach-Review instructional approach to teach strategies to support children's language development in Spanish. All sessions were at home and in Spanish. Results: Caregivers increased their use of matched turns, target talk, expansions, and a communication elicitation procedure following training on each specific skill. Additionally, caregivers generalized increased use of matched turns and target talk to an untrained activity during the intervention period and maintained their behavior 1 month after completing intervention. Two of 3 caregivers generalized their use of expansions, and 1 caregiver generalized her use of a communication elicitation procedure. Modest effects on the child's number of different words were observed for 2 of the 3 target children over the course of the intervention sessions. All 3 children demonstrated increases in total spontaneous words. Conclusion: Spanish-speaking caregivers were able to implement naturalistic language teaching strategies with their young children with language impairment in a relatively short-term intervention.

Gender differences in the relation between mothering behaviors and child-behavior problems among Hispanic preschoolers.

This is a report of an examination of gender differences in behavior problems and a prediction of their changes from 2.5 to 3.5 years from mothering qualities among 209 low-income Hispanic children. Externalizing behaviors declined over this time somewhat more for girls than for boys. Fewer externalizing behavior problems at age 3.5 were correlated with more supportive and less intrusive mothering at 2.5, but only for boys, and increases in externalizing behavior among boys were uniquely predicted by greater maternal intrusiveness. Implications for understanding parental control factors among Hispanic families are discussed.

Child Vocabulary, Maternal Behavior, and Inhibitory Control Development Among Spanish-Speaking Children.

RESEARCH FINDINGS: The roles of child lexical diversity and maternal sensitivity in the development of young children's inhibitory control were examined in 100 low-income Hispanic Spanish-speaking children. Child communication utterances at age 2½ years were transcribed from 10-min mother-child interactions to quantify lexical diversity. Maternal behavior was rated independently from the interactions. Inhibitory control was measured with a battery of tasks at ages 2½ and 3½. Greater maternal sensitivity was correlated with higher vocabulary at 2½. Greater vocabulary predicted positive growth in child inhibitory control skills from ages 2½ to 3½ in multivariable regression models that controlled for maternal education, family income, the home environment, and mothering quality. PRACTICE OR POLICY: These findings suggest that supporting vocabulary development in low-income Spanish-speaking children is important for the development of inhibitory control skills, an important foundation for school readiness and academic success.
