RESUMO

Food selectivity affects up to 72% and 45% of individuals with and without disabilities, respectively, and there is a need for interventions that rely on positive, unrestrictive strategies. We evaluated an assessment and treatment package for food selectivity for young children with developmental disabilities that prioritized caregiver collaboration, client autonomy, and did not rely on restrictive procedures (e.g. escape extinction). The process involved: (a) collaborating with caregivers on the selection of foods and design of the children's functional analyses; (b) indirectly and directly measuring food preferences prior to treatment; (c) evaluating the sensitivity of mealtime problem behavior to environmental variables through an interview-informed synthesized contingency analysis (IISCA); and (c) incorporating the assessment results into a progressive treatment process consisting of choice-making opportunities and differential reinforcement of successive approximations to consumption. Children also had the ability to opt in and out of treatment sessions. The treatment was effective in increasing consumption of nonpreferred foods and successfully extended to caregivers. Practical implications and directions for future research are discussed.

RESUMO

Saini et al. (2019) urged caution with respect to the use of practical functional assessment (PFA) procedures to inform behavioral treatment when they found that responses to an open-ended caregiver interview were only somewhat reliable and showed moderate to weak correspondence with analog functional analyses. Because the practitioner's goal in conducting any functional assessment process is to inform the successful treatment of problem behavior, we replicated and extended Saini et al. by (a) evaluating the reliability of hypotheses gleaned from two independent PFA processes for each of four children, (b) conducting treatment informed by a randomly assigned PFA, and (c) determining the extent to which potentially different levels of reliability impacted the treatment utility of the PFA process. Results indicated that the reliability of the PFA process varied depending on the stringency with which it was evaluated. However, treatments developed from randomly determined PFA processes produced efficacious outcomes on problem behavior and targeted social skills that transferred to the context designed from the other PFA process in all evaluations, suggesting that the PFA has strong treatment utility despite parts of the process having ambiguous levels of reliability. We discuss implications for practitioners tasked with treating severe problem behavior.

RESUMO

When reported, the methods for prompting functional communication responses (FCRs) following problem behavior during functional communication training (FCT) vary. Some researchers have prompted the FCR immediately following problem behavior but doing so may inadvertently strengthen problem behavior as the first link in an undesirable response chain. This study investigated the effects of prompting FCRs following problem behavior during FCT with 4 children who exhibited severe problem behavior. Problem behavior remained low and FCR rates were near optimal when prompts were delivered immediately following problem behavior for 2 participants. Delaying prompts following problem behavior was instrumental for FCR acquisition for 1 participant but led to escalation of problem behavior for a 2nd participant. The conditions under which immediate prompts following problem behavior may improve or worsen FCT are discussed.

RESUMO

Programs that prevent the development of severe problem behavior in young children with autism spectrum disorder (ASD) are critically needed. We describe a program designed to do this, and we report on a preliminary evaluation of its effects with four 3- and 4-year-old children with ASD. Parents served as the primary implementers, with twice-weekly coaching from a Board Certified Behavior Analyst. Direct measures and Aberrant Behavior Checklist scores reflected decreases in emerging problem behavior. Direct measures also reflected increases in child communication, social, and cooperation skills, and parents rated the process as highly acceptable. A randomized controlled trial will be required to evaluate the extent to which the program prevents the development of problem behavior in young children with ASD.

RESUMO

General and long-term outcomes of functional analysis training have not yet been reported. Within a randomized control trial, we trained 18 behavior analytic practitioners to interview caregivers, design and then conduct a personalized analysis as a part of a practical functional assessment (PFA). Participants were randomly assigned to groups, and those who experienced the seminar prior to conducting PFA with a confederate demonstrated more component skills than those who were provided the same materials but did not experience the seminar (mean scores: 87%, 36% respectively). Participants who experienced the seminar considered the training valuable and reported greater confidence in their ability to achieve control in an analysis. Several participants then conducted a PFA with a client who engaged in SPB. Results showed that skills transferred to these authentic applications. Results suggest that a seminar-based training can increase practitioners' ability to functionally analyze problem behavior and leads to subsequent analytic activity.

RESUMO

We replicated Shillingsburg et al. (2018) by teaching children with autism to mand for social information while analyzing the variables influencing the emission of mands. We presented questions about a social partner that were known and observable (e.g., "What is Robin doing?"), known but unobservable (i.e., questions for which an intraverbal response had previously been taught, such as, "Where does Robin work?"), or unknown (e.g., "What is Robin's favorite food?"). Correct answers were reinforced across all conditions. During treatment, we prompted children to mand for information from the social partner following only unknown questions. All children acquired mands for social information and answered previously unknown questions correctly after manding for social information and 3 of 4 participants emitted mands to novel social partners, including a peer with autism.

RESUMO

In their review of synthesis within the functional analysis (FA) literature, Slaton and Hanley (2018) reported that most synthesized contingency analyses have included multiple topographies of problem behavior in the reinforcement contingency class. This leaves the question of whether one, some, or all forms of problem behavior are sensitive to the synthesized reinforcement contingencies in published analyses. To address this ambiguity, all topographies of problem behavior that were reported by caregivers to co-occur with the most concerning problem behavior were analyzed for 10 participants. We implemented extinction across one or more forms of problem behavior to determine whether all forms reported to co-occur were sensitive to the same synthesized reinforcement contingency. For nine of 10 participants, the most concerning topographies were sensitive to the same synthesized reinforcement contingencies as the less concerning topographies (results were inconclusive for one). Implications for inferring response class membership from single analyses are discussed.

RESUMO

Response efficiency plays an important role in the initial success of functional communication training (FCT). Although low-effort functional communication responses (FCRs) have been shown to be most effective in replacing problem behavior; more developmentally advanced FCRs are favored later in the treatment process. Attempts to teach these more complex FCRs, however, often lead to the resurgence of problem behavior. In this study, we provide a detailed description of an effective shaping process applied within a changing criterion design to develop complex FCRs from simple FCRs without resurgence of problem behavior. Four children with various language and intellectual abilities participated in this study. A practical shaping procedure, suitable for typical teaching contexts, is described for two participants in Experiment 1. The necessity and efficacy of the shaping process are demonstrated with the participants in Experiment 2. Implications for practice and research are discussed.

RESUMO

Research with individuals with disabilities has demonstrated the utility of intervention approaches to address toy play, also referred to as functional leisure engagement (FLE). Examples include prompting FLE, blocking stereotypy, and differentially reinforcing appropriate FLE with social or automatic (i.e., access to stereotypy) reinforcers. Backward chaining has yet to be evaluated, but may be useful for establishing more complex FLE. The current study employed a treatment package consisting of these components with three school-aged children with autism in a therapeutic classroom. Effects were evaluated during pretest and posttest sessions, which consisted of free access to toys in a novel setting. The percentage of session with FLE was evaluated using a multiple probe design across participants. Results showed all participants demonstrated an increase in FLE and two participants showed decreased stereotypy. Feasibility for classroom implementation is discussed.

RESUMO

Previous research has evaluated contrived motivating operations to teach mands for information. However, literature evaluating acquisition of the mand when? is comparatively limited. As an extension of Shillingsburg, Bowen, Valentino, & Pierce (2014), we taught three children with autism to engage in mands for information using when under alternating conditions in which a contrived establishing operation was present (EOP) or absent (EOA). Following training with a constant prompt delay, all participants acquired the mand for information and demonstrated correct use of the provided information and a decrease in inappropriate attempts to access restricted items.

RESUMO

Using procedures similar to those of Tiger, Hanley, and Heal (2006), we compared two multiple-schedule variations (S+/S- and S+ only) to treat high-rate requests for edible items in the Picture Exchange Communication System (PECS). Two individuals with autism participated, after they showed persistent requests for edible items after PECS training. Stimulus control was achieved only with the multiple schedule that involved presentation of a discriminative stimulus during reinforcement components and its removal during extinction components (S+ only). Discriminated requests were maintained for the 1 participant who experienced schedule thinning.
