Effects of Acceptance and Commitment Training on Treatment Integrity Amongst Behavioral Technicians.

Behavioral technicians (BT) within the field of applied behavior analysis may be at greater risk for experiencing burnout and stress due to the nature of their clients, job demands, and work environments. Burnout and stress may negatively impact BT's work performances, more specifically, their treatment integrity. Acceptance and Commitment Training (ACT) may be a useful tool to address the private events as well as the covert and overt behaviors associated with burnout and stress. The purpose of this study was to investigate the effects of an ACT intervention on improving treatment integrity and reducing work-related burnout and stress amongst BTs. Four BTs participated in an ACT workshop, and their treatment integrity as well as their burnout and stress levels were measured prior to and following the ACT workshop. Treatment integrity increased for all participants, suggesting that ACT-based interventions may be an effective approach to improving work performance (i.e., treatment integrity) amongst BTs who may experience workplace burnout and stress.

An Evaluation of Contingent Gum Chewing on Rumination Exhibited by an Adolescent with Autism Spectrum Disorder.

Rumination is defined as repeated regurgitation of food, not attributed to other medical conditions. Some individuals with autism or other developmental disabilities engage in rumination, and it can lead to multiple health issues. Previous research demonstrated that noncontingent presentation of chewing gum could be an effective treatment for reducing ruminations. The current study evaluated the effects of noncontingent chewing gum and contingent gum on rumination of an adolescent boy with autism and the results suggest that both treatments were effective, but contingent gum resulted in the lowest rate of rumination. • Rumination can cause multiple health issues including malnutrition, weight loss, esophagitis, tooth decay, and abnormal gastrointestinal symptoms. • Rumination in individuals with autism is often automatically maintained. • Continuous noncontingent gum and contingent gum may be viable treatments for rumination. • Contingent gum may be a more practical intervention for rumination relative to continuous noncontingent gum.

A systematic review of the correspondence between descriptive assessment and functional analysis.

Clinicians report that they often rely on descriptive assessments when developing behavior-reduction plans despite literature suggesting that functional analysis is the most rigorous assessment method. Further, research comparing the outcomes of descriptive assessments and functional analyses is mixed, with some studies showing low correspondence and others showing high correspondence. Such persistent use of descriptive assessments suggests that they may yield useful information despite inconsistent correspondence with functional analyses. A more fine-grained analysis of the relation between descriptive assessments and functional analyses may elucidate variables affecting their utility. We conducted a review of 48 studies that included descriptive assessments and functional analyses and evaluated several measures of correspondence between each pair of assessments. Results indicated that descriptive assessments had exact correspondence with functional analyses in 50% of comparisons. Results also suggested that descriptive assessments were more likely to accurately identify and predict the absence of a function relative to the presence of a function and that structured descriptive assessments were more likely to accurately predict functions.

An individualized approach to teaching adults with autism to successfully navigate job interviews via remote instruction.

Adults with autism spectrum disorder (ASD) experience challenges securing employment, which may partially explain overall underemployment or unemployment in this population. One of the first steps to obtaining employment is participating in a job interview. However, social communication deficits may interfere with an individual with ASD's participation in a job interview. The current study evaluated the use of behavioral skills training delivered via remote instruction to teach interview skills to seven adults with ASD. Results showed overall improvement during interviews as well as posttraining tests with a career development expert. These data suggest that an individualized approach to teaching may be an effective strategy to help adults with ASD successfully navigate job interviews.

An Initial Development and Evaluation of a Culturally Responsive Police Interactions Training for Black Adolescents with Autism Spectrum Disorder.

The purpose of the current study was to conduct a qualitative and experimental analysis of a culturally informed police safety skills training for adolescents with autism spectrum disorder (ASD). The current study focused primarily on meeting the unique training needs of Black adolescents with autism spectrum disorder (ASD). A single case design was used to evaluate the initial efficacy and acceptability of a culturally responsive training method. Preliminary evidence about the physiological ramifications of police contact were also collected to begin to examine the broader behavioral and psychophysiological nature of youth's experiences. The current experimental design included in-person simulated contexts that youth, and caregivers, endorsed as relevant to their normal lives, which greatly strengthened the ecological validity of the approach.

Advancing Methods in Animal-Assisted Intervention: Demonstration of Starting Points in Clinical Practice for Children with Autism Spectrum Disorder.

Therapy animals have been frequently included in interventions for children with autism spectrum disorder (ASD); however, direct and systematic procedures such as assessing preference for and reinforcing efficacy of the animals are rarely conducted. Assessing preference for stimuli is valuable when determining how to make interventions for children with ASD most effective. We conducted paired-stimulus preference assessments and follow-up reinforcer assessments to determine if a therapy dog might be an effective reinforcer. We found one third of participants preferred the dog the least, one third of participants moderately preferred the dog, and one third of participants highly preferred the dog relative to other stimuli. Furthermore, we found preference predicted reinforcing efficacy for five of six participants. We suggest clinicians systematically conduct assessments to clearly identify the role of the therapy animal, to improve quality of, and demonstrate efficacy of interventions including animals for clinical populations.

Treatment of Food Selectivity in an Adult With Autism Spectrum Disorder.

Food selectivity is common among individuals with autism spectrum disorder (ASD). Left untreated, food selectivity may continue into adulthood, leading to social and nutritional deficits. Although effective treatments have been identified for young children and the school-aged population, these treatments may not be feasible with adults. As such, effective treatments for adults with ASD need to be identified. In this study, the participant was a 26-year-old male with ASD and a history of food selectivity. We compared two treatments that used differential reinforcement of alternative behaviors-one using positive reinforcement and the other negative reinforcement-to increase acceptance of novel fruits and vegetables. Both treatments resulted in increases in the acceptance of grapes and red bell peppers. When given the choice, the participant preferred the positive reinforcement contingency. Additionally, his food acceptance occurred in the presence of novel foods (e.g., carrots and lettuce) and settings. This study represents one of the only studies examining the treatment of food selectivity in adults with ASD.

Interobserver agreement: A preliminary investigation into how much is enough?

Interobserver agreement (IOA) is important for research and practice, and supports the consistency of behavioral data (Kahng et al., 2011). Although general parameters for how much IOA is needed have been suggested (Bailey & Burch, 2018), it is unknown if the total number of sessions with IOA might impact the IOA coefficient. In this study, IOA was reanalyzed using functional analysis data at various cutoffs. Obtained IOA from these analyses was then compared to the original IOA. Overall, results suggested that, at least when using highly trained observers in a structured clinical setting, there were no significant differences in IOA across cutoffs. However, IOA was sensitive to overall rate of responding in the functional analysis. These data are encouraging, particularly for practitioners, because they provide preliminary support that the amount of sessions with IOA may not be as important as the consistency of the data.

Feasibility of virtual reality behavior skills training for preservice clinicians.

Effective training procedures include behavioral skills training (BST), which involves providing written and verbal instructions, modeling of the skill, rehearsal of the skill, and feedback on the performance. This training typically involves in vivo experience in which trainees and students are exposed to risks such as proximity to infectious disease, behavioral issues such as aggression, and errors in teaching performance. Conducting BST in a virtual reality (VR) context involving virtual individuals with problem behavior may be an effective means of mitigating these risks. The purpose of this study was to examine the feasibility of training students to conduct functional communication training (FCT) in a VR environment using BST. We trained 13 preservice college students to implement FCT for attention and escape functions. We found VR BST was effective at increasing correct steps performed of FCT to mastery criterion levels with all participants. Future researchers should examine generalization and maintenance of VR BST.

Evaluation of Free-operant Preference Assessment: Outcomes of Varying Session Duration and Problem Behavior.

Previous researchers have found brief versions of preference assessments correspond to outcomes of longer preference assessments, and that varying levels of problem behavior occur in different preference assessments. Researchers conducted two studies to examine 1-, 2-, and 5-min duration outcomes of the free-operant preference assessment and evaluated the correspondence between the shorter and longer session durations and to identify frequency of problem behavior at each duration. Researchers also assessed relative reinforcing efficacy of the highest preferred stimulus from the shortest duration sessions. Moderate to high correlations were found between the 1- and 2-min sessions and 1- and 5-min sessions across six of eight participants diagnosed with autism spectrum disorder in Study 1 and two of three participants in Study 2. Furthermore, all highest preference stimuli identified in the shortest duration assessment served as reinforcers. Researchers found problem behavior generally occurred more in longer duration sessions.

Recent research on the relative efficiency of speaker and listener instruction for children with autism spectrum disorder.

The traditional recommendation for sequencing speaker and listener instruction has been to teach listener skills prior to teaching speaker skills. In a review of the research literature prior to 2011, Petursdottir and Carr (2011) concluded that research did not support this recommendation. We reviewed the most recent research on the efficiency of skill acquisition during speaker and listener instruction and found similar results to Petursdottir and Carr. Recommendations for future research and practice are provided.

Evaluating preference for and reinforcing efficacy of a therapy dog to increase verbal statements.

The purpose of this study was to evaluate preference for and reinforcing efficacy of a therapy dog to increase verbal statements across different contingencies. Five children with autism spectrum disorder ages 3-8 years participated. Alternating treatments and reversal designs were used to compare conditions in which (a) a therapy dog was not present, (b) access to a therapy dog was noncontingent, (c) access to a therapy dog was contingent on interacting with a therapist, and (d) access to another preferred item was contingent on interacting with a therapist. Results varied across participants. Noncontingent access to the therapy dog slightly increased verbal statements for 1 participant. Contingent access to the therapy dog increased social interactions for 2 participants; however, this was the most effective intervention for only 1 participant. Practitioners should be aware that some clients may be better suited for interventions including therapy dogs than others.

Assessment to identify learner-specific prompt and prompt-fading procedures for children with autism spectrum disorder.

Few studies have evaluated the use of assessment to identify the most efficient instructional practices for individuals with autism spectrum disorder. This is problematic as these individuals often have difficulty acquiring skills, and the procedures that may be efficient with one individual may not be for others. The experimenters conducted instructional assessments to identify the most efficient prompt type (model, partial physical, full physical) and prompt-fading procedure (progressive delay, most-to-least, least-to-most) for teaching auditory-visual conditional discriminations for individuals with autism spectrum disorder. Each assessment was conducted at least twice, and a final generality test combined the most and the least efficient prompt type and prompt-fading procedure for teaching novel auditory-visual conditional discriminations. The results demonstrated learner-specific outcomes for the prompt type assessment, whereas the least-to-most prompt fading procedure was most efficient for all participants.

A comparison of group contingencies on academic compliance.

We used a reversal design with an embedded multielement design to compare the effects of an independent group contingency and a randomized dependent group contingency on compliance with assigned literacy worksheets in a first-grade general education classroom. Nine participants were selected based on low levels of compliance in baseline or by teacher identification. Results indicated that both group contingencies increased compliance relative to baseline for the majority of participants. The independent condition produced higher levels of compliance for four students and the randomized dependent condition produced higher levels of compliance for one student. For four students, the two group contingencies were equally effective. A preference assessment indicated that the majority of target students preferred the randomized dependent condition and the majority of nontarget students preferred the independent condition. A number of potential explanations for our preference findings, including the possible role of obtained reinforcement, are discussed.

Context influences preference for and level of physical activity of adolescents with intellectual and developmental disabilities.

The purpose of the current study was to replicate and extend Hustyi, Normand, Larson, and Morley (2012) by determining the effects of different contexts on physical activity displayed by adolescents with intellectual and developmental disabilities, and determining preference for various activities. Results indicated that an exergaming condition produced the highest levels of activity. Results of a preference assessment indicated that 2 out of 3 participants preferred the physical activity context to the sedentary. For the third participant, an intervention was included to increase activity. Although the intervention was successful, participant preference for the sedentary activity context remained unchanged.

Behavioral Treatment of Self-Injury: 2001 to 2016.

Individuals diagnosed with intellectual and developmental disabilities (IDD) frequently exhibit self-injurious behavior (SIB). Previous research has examined the published literature on behavioral treatments of SIB from 1964-2000. Results suggested that these treatments were highly efficacious at decreasing SIB, particularly when based on the results of a functional assessment. The purpose of this review is to update, replicate, and extend the previous research. The current findings indicate an increase in studies reporting automatically maintained SIB as well as less efficacious treatments overall. Discussion of our conclusions and methods of SIB assessment and treatment are discussed, both as they relate to the previous review and for future directions.

Some effects of noncontingent positive reinforcement on multiply controlled problem behavior and compliance in a demand context.

Functional analysis suggested that the problem behavior of an 8-year-old girl with autism was maintained by escape from demands and access to edible items. Noncontingent delivery of an edible item was sufficient to increase compliance and reduce the rate of problem behavior without the use of escape extinction in a demand context. Leaner and richer schedules of noncontingent reinforcement were equally effective, and there were minimal differences between noncontingent reinforcement and differential reinforcement of compliance.

Descriptive assessment of problem behavior during transitions of children with intellectual and developmental disabilities.

Transitions from one activity to another may evoke problem behavior from individuals with intellectual disabilities. One explanation for the occurrence of problem behavior could be the change in relative densities of reinforcement between the two activities. We conducted a descriptive assessment of problem behavior with four children during transitions to and from several different contexts. We observed that, in most cases, the probability of problem behavior was greater during a transition to an activity with a lower density of reinforcement than during a transition to an activity with a higher density of reinforcement. We discuss our findings in terms of problem behavior associated with transitions in activities with different reinforcer densities, as well as the possibility that the problem behavior may be associated with shifts in motivating operations.

Effects of computer-based training on procedural modifications to standard functional analyses.

Few studies have evaluated methods for training decision-making when functional analysis data are undifferentiated. The current study evaluated computer-based training to teach 20 graduate students to arrange functional analysis conditions, analyze functional analysis data, and implement procedural modifications. Participants were exposed to training materials using interactive software during a 1-day session. Following the training, mean scores on the posttest, novel cases probe, and maintenance probe increased for all participants. These results replicate previous findings during a 1-day session and include a measure of participant acceptability of the training. Recommendations for future research on computer-based training and functional analysis are discussed.

Further Evaluation of Presentation Format of Competing Stimuli for Treatment of Automatically Maintained Challenging Behavior.

Behavioral interventions have been effective in reducing automatically maintained skin picking for individuals with disabilities including autism spectrum disorder (ASD). A competing stimulus assessment (CSA) is typically utilized in behavioral intervention and assessment to identify potential stimuli which compete with the reinforcer for various forms of challenging behavior (CB). Treatment evaluations have validated the results of these assessments by demonstrating competing stimuli may reduce levels of CB. In Phase 1 of this study, we conducted a functional analysis (FA) to determine what variables were maintaining skin picking of an 11-year-old girl diagnosed with ASD. In Phase 2, we conducted a CSA to determine which stimulus competed the most with skin picking. In Phase 3, we utilized a multielement with reversal design to compare the effectiveness of three presentation formats: (a) single stimulus (single), (b) multiple stimuli (multiple), and (c) alternating stimuli (alternating) in reducing levels of automatically maintained CB. We found noncontingent access to a single item was the most effective intervention to decrease skin picking. This study adds to the literature on reducing CB in children with ASD by incorporating a CSA before the evaluation of different formats of delivering competing stimuli, across extended duration session times.
