Abstract

Objective This study was carried out to examine the efficacy of a 12-week, low intensity (one-hour-per-week of therapist contact), parent-delivered intervention for toddlers at risk for autism spectrum disorders (ASD) ages 14–24 months and their families. Method A randomized controlled trial involving 98 children and families was carried out in three different sites investigating the efficacy of a parent delivery of the Early Start Denver Model (P-ESDM) (which fosters parental use of a child-centered responsive interaction style that embeds many teaching opportunities into play) compared to community treatment as usual. Assessments were completed at baseline and 12 weeks later, immediately after the end of parent coaching sessions. Results There was no effect of group assignment on parent-child interaction characteristics or on any child outcomes. Both groups of parents improved interaction skills and both groups of children demonstrated progress. Parents receiving P-ESDM demonstrated significantly stronger working alliances with their therapists than did the community group. Children in the community group received significantly more intervention hours than those in the P-ESDM group. For the group as a whole, both younger child age at the start of intervention, and a greater number of intervention hours, were positively related to degree of improvement in children’s behavior for most variables. Conclusions Parent-implemented intervention studies for early ASD have thus far not demonstrated the large effects seen in intensive treatment studies. Evidence that both younger age and more intervention hours positively affect developmental rates has implications for clinical practice, service delivery, and public policy.

  • The authors state this as an assumption.

    The project's logic model assumes that parent behavior is the causal mechanism for changes in child behavior.

    “Given that the logic model of the project assumes that parent behavior is the causal mechanism for changes in child behavior, group effects on measures of parent behavior were examined at both time points, and relations between parent behavior and child symptoms and development examined.”

  • The effectiveness of early intensive behavioral training to foster social interaction and speech development can be understood as a result of gently enforcing the child's engagement in an interaction with the social environment, which is usually too noisy and dynamic for the affected child to regard as learnable and with which it therefore does not interact spontaneously.

    “the effectiveness of early intensive behavioral training to foster social interaction and speech development (18, 19) can be understood as a result of gently enforcing the child’s engagement in an interaction with the social environment, which is usually too noisy and dynamic for the affected child to be regarded as learnable and with which it, therefore, does not interact spontaneously.”
  • In another parent-coaching RCT, groups had equal hours before randomization, but by week twelve the comparison group was getting significantly more weekly treatment (P-ESDM 1.48 [1.96]; community 3.68 [3.91], p<.05).

    “In that study, the groups had received equivalent intervention hours up until randomization. But in a very short time, by the end of the twelve-week intervention period, there was a significant difference in the number of treatment hours children (aged 12–24 months) were receiving weekly, with the comparison group receiving more intervention (P-ESDM 1.48 [1.96]; community group 3.68 [3.91], p<.05.”
  • A recent trial evaluated the ESDM in a brief format (1 hour per week of parent training for 12 weeks) and failed to detect improvements in parental intervention skill acquisition and child-related outcomes relative to community intervention controls.

    “For example, a recent trial evaluated the ESDM in a brief format: 1 hour per week of parent training for 12 weeks, as opposed to the original ESDM, which involved 20 hours per week of therapist involvement plus additional parent-mediated intervention for 2 years. 14 The study failed to detect improvements in parental intervention skill acquisition and child-related outcomes relative to community”
  • Early evaluation, diagnosis, and evidence-based interventions could enhance short-term and long-term developmental outcomes for young children with ASD.

    “Early routine screening for ASD and other developmental concerns is recommended by the American Academy of Pediatrics (1) because early evaluation, diagnosis, and evidence-based interventions could enhance short-term and long-term developmental outcomes for young children with ASD (2–6).”
  • On the basis of evidence linking early treatment to improved outcomes, it is important that children with developmental concerns be evaluated and referred to services as soon as possible.

    “On the basis of evidence linking early treatment to improved outcomes (36–39), it is important that children with developmental concerns be evaluated and referred to services as soon as possible.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Claim about intervention hours overstates the reported outcomes

    Major

    The discussion says intervention hours predicted change on every dependent variable, including reduced autism symptoms. The results instead describe an ambiguous, nonsignificant association for modified ADOS Social Affect.

  • Age conclusion adds an unsupported symptom effect

    Major

    The paper concludes that younger age was linked to greater symptom reduction, but its earlier discussion explicitly excludes autism symptom reduction from the reported age effect.

  • Nine coaching weeks are assigned ten weekly skills

    Minor

    Sessions 2 through 10 provide nine sessions, but the paper says one new skill was addressed each week across ten techniques.

  • Enrollment counts leave four referrals unaccounted for

    Minor

    The stated screening dispositions total 224 referrals, not the 228 initially reported.

    Reported 228 · recomputed 224

  • Follow-up diagnostic proportions disagree

    Minor

    If all but one child still met the ADOS-T cutoff at follow-up, the later statement that only 95% did so is inconsistent with the reported cohort of 98 children.

  • Sibling subgroup counts do not total 26

    Minor

    The two treatment-group counts add to 23 children, three fewer than the stated total with a sibling with another developmental disorder.

    Reported 26 · recomputed 23

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-06.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-06.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
