Functional analyses are used to assess maintaining variables of behavior. Despite the large amount of research on functional analyses with humans, there are limited examples with nonhumans and even fewer studies incorporating modifications to standard methods of assessment with nonhumans. One modification that has yet to be evaluated with nonhuman animals is the trial-based functional analysis in which control and test conditions are embedded in naturalistic environments. This study compared a standard functional analysis with a trial-based functional analysis across different topographies of problem behavior with dogs. The results of the functional analyses corresponded for every dog. Individualized treatments were designed to reduce problem behavior. Implications of the trial-based functional analysis include feasibility for privately owned dogs and dogs under the care of shelters. The trial-based functional analysis offers a modification to established functional analyses that may allow increased access to the assessment of problem behavior.

We replicated and extended Kanaman et al. (2022) by comparing outcomes of solitary (leisure items only), social (leisure items with social interaction), and combined (leisure items alone and leisure items with social interaction) stimulus preference assessments to determine the extent to which the inclusion of social interaction influenced the outcomes of preference assessments for five children with autism. We then conducted reinforcer assessments to determine the reinforcing efficacy of high- and low-preferred leisure items when presented with and without social interaction. The results showed that both high- and low-preferred items functioned as reinforcers to varying degrees for all participants and the inclusion of social interaction increased the reinforcing efficacy of some items for all participants. Additionally, the results showed that combined preference assessments predicted reinforcer assessment outcomes for two of five participants but produced false-negative outcomes for three participants. Clinical implications and directions for future research are discussed.

Substance use disorders (SUDs) affect millions and have substantial negative consequences for individuals and society. Social incentives that leverage social networks for reinforcement or feedback have been used to improve health behaviors such as physical activity. This study investigated the feasibility, acceptability, and usability of a novel digital social incentive system embedded into a web- and smartphone-based platform for SUD recovery. The system leveraged a preexisting care team to deliver social incentives following notifications on recovery-related goal completion and abstinence to members undergoing SUD treatment. In total, 243 notifications were sent to care-team members, resulting in 117 social incentives, nearly all of which (99.15%) were coded as positive. Treatment members and care-team members provided favorable endorsements on acceptability and usability measures. Some areas of improvement were identified, such as increasing personalization and transparency. This digital social incentive system was feasible, acceptable, and usable as an adjunct treatment component for SUD recovery.

A resurgence in research on response disequilibrium theory has prompted a concise review of the literature from the past 5 years. Response disequilibrium, also known as response deprivation, attributes reinforcement and punishment effects to constraints on free-operant baseline levels of behavior. By describing clinically relevant behaviors in terms of instrumental and contingent activities, researchers and practitioners can predict intervention outcomes with a disequilibrium model. We summarize the empirical outcomes of disequilibrium-informed interventions across six articles and discuss areas of future research.

We evaluated the effects of behavioral skills training on improving participant implementation of functional communication training with multiple schedules when working with a confederate. Behavioral skills training produced mastery-level responding for all six participants who required training, providing the first empirically supported training for this functional communication training approach. Next, we assessed durability during training challenges with (a) procedural changes to the original protocol, (b) a novel confederate with different discriminative stimuli and reinforcers, and (c) relapsed confederate destructive behavior. Training effects degraded at least once for all participants and in 62% of training challenges, although continuing to expose the participant to the challenging situations or providing postsession booster training resolved the degradation in most cases. We discuss these findings in relation to their clinical implications and directions for future research.

Using telehealth technology to deliver parent training in evidence-based intervention has been suggested to increase the accessibility of such interventions and improve skill acquisition and generalization. Within behavior analysis, global restrictions in response to the COVID-19 pandemic highlighted the need for the development of telehealth supports for families. The current research examined the online delivery of a parent-mediated implementation of the Preschool Life Skills program (PLS). Four parents completed the parent PLS program with their typically developing children (aged 3–5 years) via weekly videoconferencing sessions. A multiple-probe experimental design was employed to assess the effect of the intervention on children's preschool life skills and challenging behavior. Parental embedding of PLS strategies during daily activities was also evaluated. The results demonstrated increases in children's preschool life skills, decreases in challenging behavior, and evidence of parent acquisition and use of PLS strategies.

Inappropriate mealtime behavior (IMB) is a type of feeding challenge within the broader class of food refusal. The purpose of this study was to critically analyze the efficacy of interventions for the treatment of IMB through a meta-analysis of research using single-case experimental designs. We examined the extent to which different interventions resulted in decreases in IMB while also producing increases in food acceptance. This meta-analysis was also used to examine the efficiency of different interventions in achieving clinical significance. We identified 38 studies involving 266 cases in which IMB was treated with a behavioral intervention. The results indicated interventions that combined escape extinction and non-escape extinction had greater effect sizes for both reducing IMB and increasing food acceptance than either escape extinction alone or non-escape extinction alone. However, interventions that included escape extinction were slightly less efficient at decreasing IMB than were interventions that did not include escape extinction. We discuss the implications of these findings and provide recommendations for future research.

Parent-mediated interventions for infants and young children with an increased likelihood of autism may help ameliorate developmental concerns; however, generalization of parents' teaching strategies to novel child target skills has not been consistently demonstrated. This study expanded our parent training program, Parent Intervention for Children at-Risk for Autism (PICARA), by incorporating telehealth general case training (PICARA-TGCT) to promote generalization of teaching skills. Five parent–child dyads participated. Child target skills were chosen from the categories of imitation, receptive language, and expressive language. A concurrent multiple-baseline-across-participants design was used to evaluate the effect of training across two cohorts of parent–child dyads. Dependent variables included the percentage of correct parent teaching skills and the percentage of child correct responses. Parent teaching skills increased across all participants for both trained and untrained child target skills, as did child skills. This study provides support for PICARA-TGCT as an efficacious and efficient early intervention model.

Contingency management (CM), which involves the delivery of incentives upon meeting behavioral goals, has the potential to improve substance use treatment outcomes. The intervention allows for flexibility through numerous modifiable components including changes to incentive magnitude and schedule, target behavior, and intervention structure. Unfortunately, numerous changes in the substance use landscape have occurred in the past 10 to 15 years: Substances are more potent, overdose risk has increased, new substances and methods of use have been introduced, and substance classes are increasingly being intentionally and unintentionally mixed. These developments potentially undermine CM outcomes. We explored recent substance use changes due to legislative, regulatory, social, and economic factors for four substance classes: stimulants, opioids, tobacco, and cannabis. We discuss potential adjustments to the modifiable components of CM for future research in response to these changes. By continually adapting to the shifting substance use landscape, CM can maintain optimal efficacy.

Previous research has supported selecting development-matched targets rather than age-matched targets to teach play skills to children with autism spectrum disorder. However, few studies have been conducted, and replications and extensions of this research are needed. The current study replicated Pane et al. (2022) by comparing the acquisition of development-matched and age-matched play targets when teaching play skills to four children with autism. No contrived prompts or consequences were used to teach play skills in either condition. Extensions included identifying targets via a newer version of the Developmental Play Assessment, targeting different play categories, assessing additional imitation skills, and conducting a caregiver assessment to identify socially valid toys, play actions, and vocalizations based on each participant's common experiences and preferences as well as their caregiver's values and preferences. As in Pane et al., participants demonstrated a higher level of scripted play actions in the development-matched condition.
