Many professionals report using ABC narrative recording to identify the function of problem behavior in children with developmental disabilities, but research has not established whether their analyses yield valid results. Thus, the purpose of this study was to examine whether the function identified by expert reviewers using ABC narrative recordings would match the one identified by a functional analysis (FA) and the Questions About Behavioral Function (QABF) scale in four children with developmental disabilities. The functions identified by all twelve experts using the ABC narrative recordings matched at least one of the functions identified by the FA for three of four participants. The experts' analyses also agreed with the informant-based assessment at a statistically significant level for two of three participants with a conclusive QABF. Altogether, the results suggest that ABC narrative recording may be useful to generate hypotheses to identify the function of problem behavior, but that more research is needed before recommending its use as a standalone functional behavior assessment.

Challenging behaviors are a known predictor of high parenting stress in families of children with autism spectrum disorders. However, few studies have evaluated the effect of reducing challenging behaviors on parenting stress. The purpose of our study was to (a) examine the impact of reducing the frequency and severity of challenging behaviors on parenting stress and (b) compare the effects of family-centered support and parent education on changes in parenting stress. Both high severity of autistic symptoms and of challenging behaviors were predictors of parenting stress. Furthermore, receiving family-centered support were associated with larger reductions in parenting stress. Overall, our results suggest that reducing challenging behaviors with family-centered support may be preferable to produce collateral reductions in parenting stress.

A three-component multiple-schedule and brief reversals were used to examine the effects of differential reinforcement of other behavior (DRO) and noncontingent matched stimulation (NMS) on the automatically reinforced mouthing of a child with autism. Both DRO and NMS decreased immediate engagement in mouthing, but NMS produced larger reductions in the behavior. Furthermore, NMS produced subsequent effects (i.e., when the treatment was withdrawn) similar to those of prior access, whereas DRO marginally increased subsequent engagement in mouthing. The results suggest that NMS was a functionally matched intervention for mouthing. Implications for the assessment and treatment of stereotypy and applications for future research are discussed.

This proof-of-concept study assessed the feasibility of implementing Prevent-Teach-Reinforce-for-Young-Children (PTR-YC) program to address challenging behaviors in children with autism within the context of public, specialized early intensive behavioral intervention (EIBI) services offered in community settings. Following a two-day training and with brief weekly supervision meetings, children's EIBI educators acted as facilitators in 35 families' home environments. Small and moderate effect sizes were observed for parents' appraisals of their children's behavior and self-reported parenting stress. Recruitment and retention rates, implementation fidelity, as well as treatment acceptability from the perspective of participating parents and the organization attested to the feasibility and relevance of implementing and evaluating this program on a larger scale as part of a multi-center randomized controlled trial.
