Experimental: ImPACT group
Group of children at elevated likelihood of ASD who will receive the ImPACT intervention
|
Project ImPACT ("Improving Parents As Communication Teachers", Ingersoll & Dvortcsak, 2019) is a promising evidence-based parent-mediated intervention that is part of a class of naturalistic, developmental, behavioral interventions (NBDIs).
NBDIs involve the use of behavioral principles of learning to teach skills chosen from a developmental sequence in naturalistic play-setting and using natural rewards.
Skills selected as relevant for intervention are those that allow the child to participate more fully within reciprocal interactions with the adult.
In recent years the program has been adapted for use with infants and toddlers at elevated likelihood of ASD.
These adaptations have made this program appropriate for younger children and children who are experiencing social communication delays but do not have an ASD diagnosis.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Bigger change from baseline in Social Engagement in the intervention group compared to the no-intervention group.
Time Frame: outcome at 3 months after entry (post-test)
|
Duration of the engagement in interactive play with the adult. Consider whether the child 1) engages in interactive play, 2) follows the adult's lead in play activities; 3) sustains interactive play (e.g. by requesting for the activity to continue) and 4) initiates the adults engagement in interactive play. The total Social Engagement score will consist of a composite score of the abovementioned aspects coded during the administration of both the Communication and Symbolic Behavior Scale (CSBS) and the Early Social Communication Scales (ESCS). Higher frequency and longer social engagement time is considered positive outcome. |
outcome at 3 months after entry (post-test)
|
Bigger change from baseline in the score of imitation in the intervention group compared to the no-intervention group.
Time Frame: outcome at 3 months after entry (post-test)
|
Semi-structured social imitation task developed by B. Ingersoll, author of the ImPACT intervention programme. Semi-structured observation of interaction with experimenter. Only the object scale is used. The score ranges from 0 to 20, with higher scores corresponding to higher social imitation rates. Score increase is a positive outcome. |
outcome at 3 months after entry (post-test)
|
Bigger change from baseline in the score of intentional communication in the intervention group compared to the no-intervention group
Time Frame: outcome at 3 months after entry (post-test)
|
Composite weighted frequency of unprompted intentional triadic communication (initiations), obtained by multiplying each unprompted triadic communication act by the weight assigned to the behaviour used to communicate. The total Intentional Communication score will consist of a composite score of the abovementioned aspects coded during the administration of both the Communication and Symbolic Behavior Scale (CSBS) and the Early Social Communication Scales (ESCS). Score increase is a positive outcome. |
outcome at 3 months after entry (post-test)
|
Bigger change from baseline in attention disengagement in the intervention group compared to the no-intervention group
Time Frame: outcome at 3 months after entry (post-test)
|
Attention disengagement is defined as the time needed to shift the gaze to a peripheral target. It's measured with an Eye-tracker while presenting a well-known paradigm called Gap-Overlap task. Decrease in Attention disengagement time is considered as a positive outcome. |
outcome at 3 months after entry (post-test)
|
Bigger change from baseline in the intervention group compared to the no-intervention group in electrophysiological spectral power and connectivity (theta and alpha band) in response to social versus non-social videos, measured with EEG.

|
EEG activity recorded while children watch videos of abstract figures moving (resting-state), social scenes (nursery rhymes) and non-social scenes (toys moving).
|
outcome at 3 months after entry (post-test)
|
Bigger change from post-test in the intervention group in the score of Social Engagement compared to the no-intervention group.
Time Frame: follow-up at 6 months after post-test
|
Duration of the engagement in interactive play with the adult.
Consider whether the child 1) engages in interactive play, 2) follows the adult's lead in play activities; 3) sustains interactive play (e.g. by requesting for the activity to continue) and 4) initiates the adults engagement in interactive play.
The total Social Engagement score will consist of a composite score of the abovementioned aspects coded during the administration of both the Communication and Symbolic Behavior Scale (CSBS) and the Early Social Communication Scales (ESCS).
Score stability (after increase at outcome) or increase is a positive outcome.

Difference between intervention and no-intervention group in the severity score of the Autism Diagnostic Observational Scale - 2 (ADOS-2).
Time Frame: outcome at 9 months after entry
|
A standard measure internationally used to identify symptoms of autism. The total score ranges from 0 to 30, with a higher score corresponding to higher symptom severity. The total score results from the sum of two subscales: the Social Affect subscale (SA), with scores ranging from 0 to 22, and the Restricted and Repetitive Behavior one (RRB), with scores ranging from 0 to 8. The ADOS-2 total score is converted through an age-dependent algorithm to a diagnostic ordinal scale ranging from 0 to 10 (with higher scores indicating higher symptom severity), based on which a diagnostic classification can be formulated (no ASD, ASD, autism). A lower total score in the intervention group, as well as in a subscale score, compared to the no-intervention group is considered a positive outcome. |

Bigger change from baseline in the in the intervention group in the score of the Bayley Scales of Infant and Toddler Development - Third Edition - NL compared to the no-intervention group.
Time Frame: outcome at 9 months after entry
|
An age-appropriate measure of cognitive, language, motor and social-emotional development for children from 0 to 42 months.
A high growth rate (= the change in months is higher than the number of months actually passed between baseline and follow-up) in a domain where a child initially showed a delay is considered a positive outcome.

outcome at 9 months after entry
|
Bigger change from baseline in the intervention group score of the Nijmeegse Ouderlijke Stress Index compared to the no-intervention group.
Time Frame: outcome at 9 months after entry
|
Questionnaire over Parenting stress index developed in Nijmegen. Scores range from 0 to 738, distributed over two main subscales: parent-related stress and child-related stress. Each subscale is composed of subdomains. The parent-related stress is described by competence, role restriction, attachment, depression, health, social isolation, marital relationship. The child-related stress is described by adaptation, temperament, distractibility, demandingness, positive reinforcement, acceptance. An algorithm converts the subscores and the total score to a descriptive classification of parental stress level. Special norms hold for clinical samples. Higher values correspond to higher parental stress. A score reduction is a positive outcome, in particular if lower than the no-intervention group. |
outcome at 9 months after entry
|
Bigger change from baseline in the intervention group score of the Vineland screener questionnaire (0-6 years) compared to the no-intervention group.
Time Frame: outcome at 9 months after entry
|
Questionnaire to assess adaptive skills. The composite score is computed as the sum of subscale scores: communicative skills (0-38), social skills (0-38), everyday skills (0-16), motor skills (0-36). Raw scores can be converted to adaptive age. Score stability (after increase) or increase is a positive outcome, in particular if higher than the no-intervention group. |
outcome at 9 months after entry
|
Difference between intervention and no-intervention group in language.
Time Frame: outcome at 9 months after entry
|
Language will be investigated with the Dutch adaptation of the MacArthur Communicative Development Inventories (CDI), Words and Gestures (8-18 months) and Words and Sentences (16-30 months), which consists of a parent report of language development (both comprehension and production). Higher score in the intervention group is considered a positive outcome. |
