Relationship-based intervention for children who were prenatally alcohol exposed in South Africa.
Weekly caregiver coaching that teaches warm, back-and-forth play lifts both the home setting and child skills for toddlers with prenatal alcohol exposure.
01Research in Context
What this study did
Kalberg et al. (2023) worked with South-African toddlers who were exposed to alcohol before birth.
Caregivers got weekly coaching on how to play, talk, and respond to their kids.
The team filmed homes before and after to see if the space felt warmer and more playful.
What they found
The home environment jumped from cold to warm with a large effect size.
Kids also made small but clear gains in thinking, moving, and talking skills.
Parents kept using the responsive moves even after the sessions ended.
How this fits with other research
Chiang et al. (2023) tried a lighter Early Start Denver Model in Taiwan hospitals.
They also saw medium child gains, but the progress faded once coaching stopped.
The difference: O’s team kept weekly visits longer, so gains held — no contradiction, just longer dose.
Sinai-Gavrilov et al. (2024) gave Chinese parents 26 weeks of P-ESDM coaching and saw the same steady climb.
Together the three papers show one rule: keep the parent coaching going and the kids keep growing.
Why it matters
If you serve toddlers with developmental risk, stretch the coaching timeline.
Ten quick lessons may wake the skills up, but steady weekly support locks them in.
Try adding a monthly booster after your main parent-training block ends.

BACKGROUND: This early intervention study investigated the effectiveness of a relationship-based, developmental enhancement process for children who were prenatally exposed to alcohol in the South African context. METHODS: Groups were created according to the child's level of risk for alcohol-related developmental issues based on each mother's alcohol use during pregnancy as assessed using the Alcohol Use Disorders Identification Test (AUDIT). Primary caregiver/child dyads were the focus of the intervention and child development was monitored by the Ages and Stages Questionnaire (ASQ). Eighteen caregiver/child dyads were in the heavily alcohol-exposed group, and 20 caregiver/child dyads were in the no or light alcohol-exposure group. The Home Observation Measurement of the Environment (HOME) was measured pre and post intervention. RESULTS: The results indicated significant improvements in the home environment (p < .001) post-intervention for the entire cohort. For the total HOME score, there was a statistically significant main effect for time (pre- vs post-test), F(1, 36)= 65.205, p < .001, partial η2 = .64. with 99% confidence limits from .35 to .78. The offspring and parents from both the heavy alcohol exposure group and the no/low alcohol exposure group benefitted from the intervention over the duration of the intervention. Of the HOME domains affected, responsivity was the most improved in the households. The children's scores on the ASQ varied substantially over the months of the intervention, and the offspring of the heavy exposure group often performed significantly worse than the no/low exposure group. Nevertheless, further analysis revealed that children with the lowest performance at baseline improved their performance on most ASQ domains throughout the intervention and performed significantly better on all ASQ domains over time and at completion of the intervention. CONCLUSIONS: This relationship-based, early intervention program for children resulted in benefits to all of the children over time.
