ABSTRACT
Response interruption and redirection (RIRD) is a common treatment for automatically reinforced vocal stereotypy; it involves the contingent presentation of task instructions. Tasks that are included in RIRD are typically selected based on caregiver report, which may affect the efficacy of RIRD. The purpose of the current study was to evaluate the role of task preference in the efficacy of RIRD for four participants who engaged in vocal stereotypy. We conducted task-preference assessments and selected tasks of varying preferences to include in RIRD. For three out of four participants, the results showed that RIRD with higher preference tasks was not effective at reducing vocal stereotypy, whereas RIRD with lower preference tasks was effective for all participants.

We evaluated a noncontingent reinforcement treatment that included initial brief exposures to signaled alternation of availability and nonavailability of reinforcement, followed by rapid schedule thinning. Results confirmed findings from previous research (typically with differential reinforcement schedules) that establishing stimulus control across multiple treatment components facilitated schedule thinning. We discuss both the clinical utility of this procedure and the utility of stimulus control for making interventions more practical for clinicians.
ABSTRACT
Slaton and Hanley (2016) compared the effects of multiple and chained schedules on stereotypy and item engagement for 2 individuals who exhibited automatically maintained motor stereotypy. Contingent access to motor stereotypy (i.e., chained schedules) was more effective than time-based access (i.e., multiple schedules) at reducing motor stereotypy, increasing item engagement, and establishing stimulus control for both participants. We systematically replicated Slaton and Hanley with 2 participants by a) targeting vocal stereotypy, b) including response interruption and redirection as a treatment component across conditions, c) conducting sessions in the natural environment with teaching assistants as change agents, and d) conducting an analysis of the effective treatment component(s). Chained schedules were more effective for 1 participant, whereas both treatments were effective for the other participant. The component analysis showed that different components were necessary for effective treatment for each participant.

Despite the utility of experimental functional analysis methodology, not all applications produce differentiated results. Factors such as interaction effects or methodological inefficiencies may compromise the likelihood of obtaining differentiated outcomes. Various studies have addressed methods to improve the efficiency of experimental functional analysis methodology (e.g., analysis of within-session responding). In the current study, we describe an updated model for progressing from brief to extended experimental analyses. The model incorporates several procedural refinements developed over the past 20+ years of experimental functional analysis research and additional conditions to confirm or annul findings. We present data for 20 participants who were referred for assessment and treatment of a variety of behavior problems (e.g., stereotypy, aggression, self-injury). We generally terminated the analyses when response patterns were consistent with established best-practice functional analysis methodology. Results showed conclusive interpretations were obtained for 100% of participants.

The use of token systems has been supported across a variety of populations, but little research has evaluated the reinforcing value of token systems for individuals with autism. We used progressive-ratio schedules to compare the reinforcing value of an established token system, primary reinforcement, and tokens unpaired with reinforcement. Token systems were variably reinforcing for 2 students with autism and more so than primary reinforcement for 1 student. Results support formal assessment of the effectiveness of token systems.

Functional analysis procedures have been effectively used to determine the maintaining variables for challenging behavior and subsequently develop effective interventions. However, fear of evoking dangerous topographies of maladaptive behavior and concerns for reinforcing infrequent maladaptive behavior present challenges for people working in applied settings. The present investigation sought to evaluate the utility of an adjunctive functional analysis model that involved the reinforcement of mands rather than problem behavior and compared the results to traditional functional analyses. The results from the manding analysis yielded results similar to the traditional FA in 3 of 4 cases. These findings suggest that manding analyses may represent a useful assessment tool for difficult to assess problem behavior or for individuals in settings where consultative support is limited.

This study evaluated how children who exhibited functionally equivalent problem and appropriate behavior allocate responding to experimentally arranged reinforcer rates. Relative reinforcer rates were arranged on concurrent variable-interval schedules and effects on relative response rates were interpreted using the generalized matching equation. Results showed that relative rates of responding approximated relative rates of reinforcement. Finally, interventions for problem behavior were evaluated and differential reinforcement of alternative behavior and extinction procedures were implemented to increase appropriate behavior and decrease problem behavior. Practical considerations for the application of the generalized matching equation specific to severe problem behavior are discussed, including difficulties associated with defining a reinforced response, and obtaining steady state responding in clinical settings.

Differential reinforcement of alternative behavior (DRA) is used frequently as a treatment for problem behavior. Previous studies on treatment integrity failures during DRA suggest that the intervention is robust, but research has not yet investigated the effects of different types of integrity failures. We examined the effects of two types of integrity failures on DRA, starting with a human operant procedure and extending the results to children with disabilities in a school setting. Human operant results (Experiment 1) showed that conditions involving reinforcement for problem behavior were more detrimental than failing to reinforce appropriate behavior alone, and that condition order affected the results. Experiments 2 and 3 replicated the effects of combined errors and sequence effects during actual treatment implementation.

A functional analysis for a boy with Down syndrome and autism suggested that vocal stereotypy was maintained by automatic reinforcement. The analysis also showed that instructions and noncontingent attention suppressed vocal stereotypy. A treatment package consisting of noncontingent attention, contingent demands, and response cost effectively reduced vocal stereotypy. The treatment package remained effective even when noncontingent attention was removed, making the procedure easier to implement. Also, the presence of the therapist in the room with the participant was faded systematically. After completion of fading, vocal stereotypy remained low during conditions similar to the no-consequence phase of the functional analysis.

Data reliability and treatment integrity have important implications for clinical practice because they can affect clinicians' abilities to accurately judge the efficacy of behavioral interventions. Reliability and integrity data also allow clinicians to provide feedback to caregivers and to adjust interventions as needed. We present reasons why reliability and integrity measures are paramount in clinical work, discuss events that may result in decreased reliability or integrity, and provide several efficient means for collecting data and calculating reliability and integrity measures.
ABSTRACT
Ten individuals, residing in a treatment facility specializing in the rehabilitation of sex offenders with developmental disabilities, participated in an arousal assessment involving the use of the penile plethysmograph. The arousal assessments involved measuring change in penile circumference to various categories of stimuli both appropriate (adult men and women) and inappropriate (e.g., 8- to 9-year-old boys and girls). This approach extends the existing assessment literature by the use of repeated measurement and single-subject experimental design. Data from these assessments were analyzed to determine if clear and informative outcomes were obtained. Overall, three general patterns of results emerged. Some participants showed differentiated deviant arousal or higher levels of arousal to specific inappropriate stimuli (deviant is a term used in the existing sex-offender literature to describe this type of arousal). Other participants showed undifferentiated deviant arousal, in which case they showed nonspecific arousal to inappropriate stimuli. The remaining participants showed no arousal to inappropriate stimuli but did show arousal to appropriate stimuli. Implications for assessment, treatment, and future directions are discussed.

We conducted descriptive observations of 5 individuals with developmental disabilities and severe problem behavior while they interacted with their caregivers in either simulated environments (an inpatient hospital facility) or in their homes. The focus of the study was on caregiver reprimands and child problem behavior. Thus, we compared the frequency of problem behavior that immediately preceded a caregiver reprimand to that immediately following a caregiver reprimand, and the results showed that the frequency of problem behavior decreased following a reprimand. It is possible that caregiver reprimands are negatively reinforced by the momentary attenuation of problem behavior, and the implications for long- and short-term effects on caregiver behavior are discussed.

Prior researchers have evaluated the efficacy of using the matching law to describe naturally occurring behavior-environment interactions. However, spurious matching could be obtained if the response and environmental event were correlated, even if the event did not reinforce the response. To assess the likelihood of obtaining spurious matching when relating attention and problem behavior, we evaluated the problem behavior of 3 participants for whom attention did not serve as a reinforcer for problem behavior in a functional analysis. Both the simple and generalized matching equations were used to examine matching relations extracted from descriptive observations that were conducted in the participants' classrooms. The results of aggregated matching analyses showed that the proportional rate of responding approximately matched the proportional rate of contiguous adult attention. Matching analyses conducted for all participants showed correlations between attention and problem behavior. These results demonstrate that spurious matching can be obtained, and they highlight the role of functional analyses in the analysis of naturally occurring matching relations.
