This study compared the effects of video feedback (VF) as a stand-alone intervention and video modeling plus video feedback (VMVF) for improving soccer players' static ball control skills. Research has suggested that VF alone and VMVF produce substantial improvements for young athlete's skills, though no studies have compared the two. Therefore, we used a multiple-baseline-across-participants design with embedded alternating treatments to compare VF and VMVF. Two 10-year-old female soccer players and one 9-year-old male soccer player participated. The first author implemented the VF and VMVF training procedures and assessed the same three target behaviors across participants. The results suggested that VF and VMVF produced similar increases in performance for two of three participants and that VMVF produced slightly greater increases for one participant. In addition, both interventions were effective at substantially improving ball control skills from baseline levels and relative to a control skill.

The Good Behavior Game (GBG) is an effective procedure for reducing disruptive classroom behavior. Students in three fifth-grade classes selected the rules of the GBG and then experienced the GBG with different forms of feedback for rule violations (vocal and visual, vocal only, visual only, no feedback). Following an initial baseline, the four feedback versions of the GBG and a baseline condition were alternated across sessions in a multielement design. All versions of the GBG substantially reduced disruptive behavior below baseline levels. Additionally, in one of the three classes losing the GBG produced an increase in negative peer interactions immediately following the GBG. Following the multielement comparison, we implemented a group-arrangement concurrent-chains preference assessment in which students selected one of the conditions to experience each day. The most selected condition across all classes was the GBG condition, which included both vocal and visual feedback.

A competing stimulus assessment is used to identify stimuli that are associated with a low level of challenging behavior and a high level of engagement. These stimuli are often used as a treatment component for challenging behavior that is maintained by automatic reinforcement. One limitation of implementing competing stimulus assessments is that they may be time consuming. The purpose of the current study was to evaluate the efficacy and efficiency of a latency-based competing stimulus assessment. During the asssessment, a therapist presented potential competing stimuli to the participants and contingent on the first occurrence of challenging behavior, the trial was terminated. The results of a brief treatment evaluation indicated that stimuli that were associated with the longest latency to challenging behavior were more effective in competing with challenging behavior relative to stimuli that were associated with shorter latencies. However, procedural modifications were necessary for one participant. The use of latency-based measures improved the efficiency of conducting a competing stimulus assessment.

When applied to functional analysis results, structured visual inspection criteria have resulted in improvements in the levels of agreement between raters as well as earlier identification of the function of challenging behavior. However, multistep criteria can be difficult to apply in real time, which could be a barrier to widespread adoption in practice. This study evaluated a Microsoft-Excel-based functional analysis decision support system (FADSS), which could aid behavior analysts with interpreting functional analysis results. Final overall agreement between the FADSS and post hoc visual inspection was high at 95%. Final overall agreement between the post hoc results generated by FADSS and ongoing results generated by FADSS was acceptable at 81%, representing a 50% increase in efficiency. These results indicate that FADSS could aid behavior analysts when interpreting functional analysis results in real time.

Modern medical training consists largely of lecture-based instruction and in vivo or video modeling of specific skills. Other instructional methods, such as teaching with acoustical guidance (TAGteach), have rarely been evaluated. In this study, we compared teaching with tactile guidance, or tactile TAGteach in which a vibratory stimulus is delivered to indicate a correct response, with video modeling and self-evaluative video feedback to teach four participants two medical skills: simple interrupted suture and endotracheal intubation. The results showed that both instructional methods improved performance. However, three participants met the mastery criterion in the tactile TAGteach condition first, although this instructional method required more time to train the skills. We discuss the implications of these findings for training skills to medical practitioners.

Contingency management is especially effective in supporting medication adherence and drug abstinence among people with opioid use disorder. However, the incorporation of contingency management into clinical practice has been slow. The present study was designed to evaluate the feasibility, acceptability, and usability of incentives for providers as a means of accelerating collaborative care with contingency management. Thirteen buprenorphine prescribers served as participants in a nonexperimental study. The prescribers who referred patients to a contingency-management service received monetary incentives for reviewing patient performance data and describing their use of these data in treatment decisions. The results show that this approach is feasible, acceptable, and easy to use for everyone involved. Self-reports indicate improved prescriber-patient relationships and more informed care. However, prescriber-focused incentives did not appear to greatly enhance access to contingency-management services for patients. Thus, provider incentives may be beneficial but further research is needed to advance adoption of contingency management.

This article is a transcription of Murray Sidman's presentation at the annual meeting of the Society for the Quantitative Analysis of Behavior in May 1998. It describes the development (from 1965 to 1975) of behavior-change programs implemented outside the animal laboratory to benefit humans before such application was established formally as an entity derived from the experimental analysis of behavior. The presentation illustrates the use of an inductive method in practice, where working with a fluid behavior stream entails making intervention decisions on the spot. Examples include fading and backward-chaining procedures in the establishment and stimulus control of novel actions. Sidman also discusses the certification of practitioners and the interaction between client and therapist and between basic and applied endeavors. The latter define what is contemporaneously described as translational intervention. It is noteworthy that Sidman's presentation was at a meeting attended by both practitioners and scientists.

The purpose of the present experiments was to systematically replicate Step it UP! Game interventions with adults with disabilities. Participants were divided into two competing teams, and the team with the highest step count participated in a prize drawing. Experiment 1 (N = 9) evaluated the efficacy of an extended version of the Step it UP! Game that included additional and longer sessions. Experiment 2 (N = 8) evaluated the addition of contingent experimenter attention during the Step it UP! Game. Baseline, Step it UP! Game, and Step it UP! Game plus interaction sessions were evaluated in a multielement design. The Step it UP! Game was effective with additional and longer sessions, and all participants took more steps during Step it UP! Game sessions. Adding experimenter interaction to the Step it UP! Game did not increase the efficacy of the intervention.

Pairing is a commonly recommended practice used to build rapport and create positive therapeutic environments. However, there are limited evaluations of training procedures to teach pairing skills to direct-care staff. The purpose of the present study was to formalize and improve the efficiency of the training process for the initial stages of pairing using video modeling with embedded voice-over instructions plus performance feedback. Participants included three dyads of behavior technicians and children with autism. The results indicated that the training package increased the consistency of pairing implementation. These outcomes were maintained in a novel setting and for up to 4 weeks following training. We also measured relevant child behaviors such as joint attention, engagement, indices of happiness, and calm. Specific areas for future research are described.
