Children with autism spectrum disorder (ASD) often exhibit challenging behaviors. Existing behavioral parent trainings (BPT) address ASD symptomology, but are lengthy and associated with significant attrition. In the current pilot study, a longitudinal randomized controlled trial was used to evaluate a novel brief BPT targeting caregivers of children with ASD ages 5-9. The 6-session BPT, delivered in a group format, focused on high-frequency challenging behaviors (e.g., problem behaviors, feeding and sleep issues). Caregivers who received BPT (n = 29), relative to an active control (psychoeducation/supportive therapy; n = 9), reported higher treatment satisfaction and acceptability. Challenging behaviors were reduced in the BPT and active control groups. The novel BPT was a feasible and acceptable intervention to target challenging behaviors in youth with ASD.

Functional communication training (FCT) is one of the most commonly prescribed interventions for the treatment of severe destructive behavior exhibited by individuals with intellectual disabilities. Although highly effective, FCT has been shown to fail in some cases when treatment is introduced into the child's typical environment. Basic and translational research on renewal provides a model for studying the relapse of destructive behavior following successful response to treatment in clinic settings using FCT. In the present study, we evaluated whether relapse of destructive behavior could be attributed to the discriminative control of the home context, which was historically correlated with reinforcement for destructive behavior. We implemented baseline contingencies in the home setting with caregivers acting as interventionists (i.e., Context A). We then implemented FCT in a treatment clinic with trained therapists (i.e., Context B). Finally, we introduced FCT in the home setting with caregivers implementing the treatment procedures (i.e., return to Context A). For three of four participants we observed the relapse of destructive behavior consistent with operant renewal. We discuss the implications of these findings with respect to strategies designed to promote generalization of FCT across settings during the treatment of severe destructive behavior.

Laboratory research has shown that when subjects are given a choice between fixed-ratio and bi-valued mixed-ratio schedules of reinforcement, preference typically emerges for the mixed-ratio schedule even with a larger ratio requirement. The current study sought to replicate and extend these findings to children's math problem completion. Using an ABCBC reversal design, four fourth-grade students were given the choice of completing addition problems reinforced on either a fixed-ratio 5 schedule or one of three mixed-ratio schedules; an equivalent mixed-ratio (1, 9) schedule, a mixed-ratio (1, 11) schedule with a 20% larger ratio requirement, and an equally lean mixed-ratio (5, 7) schedule without the small fixed-ratio 1 component. This was followed by a reversal back to the preceding phase in which preference for the mixed-ratio schedule had been observed, and a final reversal back to the mixed-ratio (5, 7) phase. Findings were consistent with previous research in that all children preferred the mixed-ratio (1, 9) schedule over the equivalent fixed-ratio 5 schedule. Preference persisted for the leaner mixed-ratio (1, 11) schedule for three of the four children. Indifference or preference for the fixed-ratio 5 alternative was observed in phases containing the mixed-ratio (5, 7) schedule. These results extend previous research on risky choice to children's math problem completion and highlight the importance of a small ratio component in the emergence of preference for bi-valued mixed-ratio schedules. Implications of these results for arranging reinforcement to increase children's academic responding are discussed. [ABSTRACT FROM AUTHOR]

This study replicated previous basic research into the dynamics of choice and extended this analysis to children's behavior in a naturalistic setting. Two preschoolers with disabilities were observed interacting with their teachers at baseline and during an experimental analysis involving four pairs of concurrent variable-interval schedules of adult attention implemented by an experimenter. Each child was exposed to four experimental phases in which the relative reinforcer rates for on- and off-task behavior were 10:1, 1:1, 1:10, and reversed back to 10:1. The 10:1 phase was designed to mimic the same schedules and types of adult attention observed at baseline. We used the generalized matching equation to model steady-state behavior at the end of the transition phases and to evaluate changes in sensitivity at various points throughout the phases. Choice in transition was evaluated by plotting log behavior ratios by session, cumulated time on- and off-task and cumulated attention for on- and off-task behavior by session, and interreinforcer behavior ratios following different sequences of the first four reinforcer deliveries. The generalized matching equation accounted for a large proportion of variance in steady-state responding, sensitivity values increased steadily throughout the phases, patterns of choice in transition were similar to those reported in basic research, and interreinforcer preference generally shifted toward the just-reinforced alternative. These findings are consistent with previous basic research and support the generality of the dynamics of choice to children's on- and off-task behavior reinforced by adult attention.
