Only 25% of adults meet both aerobic and strength training recommendations for physical activity. Contingency management interventions have been used to increase physical activity; however, they may be cost prohibitive. Intermittently provided incentives lower costs and are effective for various health behaviors. The present study investigated whether intermittent cash incentives can increase physical activity (step counts). The researchers used a reversal design with 21 participants, and goals during the intervention were set using a percentile schedule. Contingent on meeting goals, participants could earn the opportunity to draw tickets that corresponded to either no cash or cash incentives. Step counts significantly increased from baseline to the intervention phase. Overall, intermittent cash incentives may be a viable and cost-effective approach to promoting health behavior.

Many researchers have evaluated how characteristics of feedback may influence trainee performance, but relatively little attention has been allocated to directly assessing trainee preference for feedback characteristics and its relation to performance. Thus, the primary purpose of this study was to use a within-subject experimental design to directly assess trainee preference for the frequency of feedback and its relation to task performance. A secondary objective was to evaluate how trainee preferences varied across specific task components based on component complexity. Thirty-five undergraduate students completed two arbitrary tasks and were given the opportunity to request feedback after each component of the task. For 85.71% of our participants, an inverse relation was observed between preference for feedback frequency and task performance. Participants requested feedback less often as performance improved. Feedback preferences also varied with the complexity of each component of the task. Implications for training, supervision, and feedback practices are discussed.

Among the developmental milestones related to language and communication in early childhood, one that has been the subject of considerable research is response to name (RTN). Delayed or absent RTN in early childhood is a diagnostic marker for autism spectrum disorder and a target behavior in many early intervention curricula. This article describes two related studies. Study 1 evaluated the efficacy and efficiency of a behavioral screening-to-intervention model for RTN proposed by recent research. Overall, trials to mastery were reduced relative to previous research. Study 2 evaluated the efficacy of using behavioral skills training to teach caregivers to implement a RTN intervention with their child after that intervention was successful in a clinical setting. Generalized improvements in RTN with caregivers sometimes occurred but did not maintain without programmed reinforcement. Subsequent behavioral skills training was associated with increases in both child RTN and caregiver intervention fidelity.

Behavior analysts typically assess and treat challenging behavior after it occurs regularly and at high severity. Although effective, this reactive approach is quite costly and resource intensive. A growing literature supports an alternative preventive approach; the first step involves conducting sensitivity tests to screen the topographies and functions of low-severity behavior evoked by establishing operations commonly included in challenging behavior research (e.g., Fahmie et al., 2020). Despite the potential value of sensitivity tests, their correspondence with functional analyses has yet to be established. This study measured the correspondence between social reinforcer classes nominated by sensitivity tests and social reinforcer classes verified by traditional functional analysis outcomes of the same behaviors. Participants included 10 young autistic learners who were reported to exhibit low-severity challenging behavior. Data showed generally high correspondence between both assessment outcomes for challenging behavior but not for appropriate requests.

Several studies have examined the prevalence of behavioral relapse among individuals with intellectual and developmental disabilities following common treatment challenges (context changes, schedule thinning). Most applied studies compare behavior during the treatment challenges with the maximum level of behavior from five preceding treatment sessions. This max-of-5 criterion could inadvertently capture behavior in transition during the preceding treatment phase, thereby underestimating the prevalence of relapse. In the current study, we reanalyzed existing clinical data with the max-of-5 criterion and an alternative criterion less likely to capture target behavior in transition—the mean of the last two sessions (mean-of-2 criterion) of the treatment phase. As hypothesized, the max-of-5 criterion produced lower prevalence estimates relative to the mean-of-2 criterion. We encourage researchers conducting these analyses to weigh different approaches to reporting prevalence data and discuss considerations for future areas of research and practice related to measurement of relapse.

Resurgence is the recurrence of target behavior (e.g., challenging behavior) during a worsening of reinforcement conditions (e.g., increases in response effort, decreases in alternative reinforcement). Previous studies have examined the prevalence and magnitude of resurgence during functional communication training implemented with discriminative stimuli. We conducted a systematic review of the literature to analyze the magnitude and prevalence of resurgence during delay-and-denial tolerance teaching. Similar to previous studies with discriminative stimuli, resurgence occurred for most participants and in about one third of transitions. When resurgence was present, challenging behavior increased to approximately 26% of baseline levels. Resurgence was less likely to occur during response-effort manipulations (i.e., complexity teaching, tolerance-response teaching) and was most likely to occur during increases in delays that ended following the passage of time rather than a response criterion. We discuss implications for treatment refinements and future treatment-relapse research.

Previous research has shown that low procedural fidelity can lead to decreased effectiveness and efficiency of skill acquisition during discrete-trial instruction. Previous research has also found that procedural fidelity may be substantially lower when a supervisor is not present to observe the session. Finding a socially acceptable, effective, and efficient method to increase and maintain high levels of staff members' procedural fidelity during covert observations is critical in the clinic setting. The purpose of the current study was to examine the effectiveness of video self-monitoring in increasing and maintaining high procedural fidelity among staff who implement discrete-trial instruction during covert and overt observations. Participants included four staff members working one-on-one with children with autism spectrum disorder. The results show that video self-monitoring was effective at increasing staff members' procedural fidelity and maintaining high fidelity over time.

Many individuals with Down syndrome are diagnosed with obstructive sleep apnea (OSA), a medical condition that substantially affects health and quality of life. The most common treatment for OSA is positive airway pressure (PAP) therapy. Few studies have examined interventions to improve PAP therapy adherence for adults with developmental disabilities or have recruited the assistance of caregivers to improve adherence with this therapy in the home. This study evaluated the efficacy of a caregiver-implemented behavioral intervention to increase PAP use for four adults with Down syndrome and OSA. The experimenters trained caregivers via telehealth to implement the intervention in their homes. The intervention consisted of graduated exposure, noncontingent reinforcement, and differential positive and negative reinforcement without escape extinction. The intervention increased the duration of PAP use for all four participants. These results provide preliminary support for the efficacy of this intervention and service-delivery model.

Understanding of the correspondence between intervention preference and efficacy is limited. We systematically reviewed 112 articles (457 cases) evaluating efficacy of and preference for behavioral interventions. We analyzed the percentage of cases for whom interventions were preferred and efficacious across broad (e.g., behavior reduction, performance, skill acquisition) and specific (e.g., noncontingent reinforcement, video modeling) intervention types. Authors reported one preferred intervention for most cases. Regarding efficacy, authors reported about half of cases as having one efficacious intervention and the other half having multiple equally efficacious interventions. The same intervention was preferred and efficacious for 74% of cases for whom authors reported one preferred and one efficacious intervention. Several specific interventions were generally preferred and efficacious across cases (e.g., digital stimuli, computer-based instruction, accumulated reinforcement, contingent reinforcement). We discuss clinical recommendations, the importance of assessing preference, and the need for research in developing protocols for assessing intervention preference.
