1. Objectifs

Intentions :
«The primary objectives of our study were to examine the effects of the IWT [interactive web training] alone on the frequency and severity of challenging behaviors, reported use of behavioral interventions by parents, and parenting practices.» (p. 773)

Questions/Hypothèses :
«We hypothesized that following the completion of the IWT, parents would report lower frequency and severity of challenging behavior, more frequent use of behavioral interventions, and improved parental practices.» (p. 773)

2. Méthode

Échantillon/Matériau :
«Individuals were eligible to participate in the study if [t]hey were the parent or primary caretaker of a child 12 years of age or younger with a formal diagnosis of ASD1, [their child presented challenging behaviors as confirmed by a frequency score of at least three and a severity score of at least two on one or more items of the Behavior Problems Inventory-01[,] they lived in the province of Québec, Canada, and [t]hey understood French. […] Forty-seven parent/child dyads met all the inclusion and exclusion criteria with the parent providing informed consent to participate.» (p. 773)

3. Résumé

«Our results indicate that parents in the experimental group reported using more behavioral interventions and observed lower frequency and severity of challenging behaviors in their child than parents on the waiting list for 4 weeks after completing the IWT. These changes persisted up to 12 weeks after the training. Surprisingly, the medium-to-large effect sizes observed for our fully self-administered short-duration IWT were comparable to previous research evaluating in-person, personalized parent trainings […]. On the other hand, we did not find the IWT to significantly improve parenting practices […]. [Moreover,] one of the main concerns reported by parents related to their child experiencing discomfort or side-effects during the implementation of the behavioral interventions. Through the IWT, parents learned about the possible short-term side-effects of some interventions such as extinction, which probably explains these results. As we did not measure the side-effects or discomfort directly, we do not know whether these concerns materialized when the parents implemented some of the interventions. The results indicate that it would be essential to implement a side-effect monitoring system in the future and to provide on demand support from a practitioner when the intervention produces undesirable consequences. Parents also reported that implementing the treatment may be time consuming and effortful, underlying the need to integrate strategies to support and encourage parents during implementation.» (p. 784)
