AbstractStudies suggest that reduced‐nicotine cigarettes decrease nicotine intake and dependence. However, questions remain about reduced‐nicotine cigarette abuse liability, whether reduced‐nicotine cigarette exposure lowers reduced‐ and full‐nicotine cigarette use, and whether reduced‐nicotine cigarettes substitute for full‐nicotine cigarettes. This randomized, double‐blind laboratory study used operant behavioral economics to examine abuse liability of cigarettes with varying nicotine content. Non‐treatment‐seeking smokers (N = 43) self‐administered reduced‐ (5.2, 2.4, or 1.3 mg/g) and full‐nicotine (15.8 mg/g) cigarettes before and after 3 weeks of at‐home exposure. Participants were randomized to full‐nicotine or one of the reduced‐nicotine cigarettes to determine the effect of exposure on abuse liability and substitutability. Abuse liability was assessed in single‐commodity sessions, and substitutability was measured in concurrent‐commodity sessions. In the self‐administration sessions, concurrently available reduced‐nicotine cigarettes attenuated full‐nicotine cigarette demand and rendered reduced‐nicotine cigarettes partial substitutes for full‐nicotine cigarettes. Exposure to study cigarettes for 3 weeks marginally reduced demand for reduced‐ and full‐nicotine cigarettes irrespective of nicotine content. Results suggest a limited influence of nicotine content on smoking behavior in established smokers and highlight the role of nonpharmacological factors (e.g., taste/smell) on the maintenance of smoking. These results should be considered in determining whether a nicotine‐reduction standard is a feasible path for reducing cigarette demand.

AbstractCarrigan and Sidman Journal of the Experimental Analysis of Behavior, 58, 183-204, (1992) proposed that select and reject arbitrary conditional relations are equivalence relations, each resulting in the emergence of alternative stimulus equivalence classes. The standard matching to sample (MTS) procedure can potentially teach both select and reject conditional relations, which apparently would prevent the emergence of equivalence relations, although there is extensive evidence for the emergence of equivalence with the standard MTS procedure. One possibility is that participants trained with the standard MTS procedure predominantly learn one type of control over the other. Experiment 1 explores the implementation of a Detached-MTS procedure, which separately trains the select and reject conditional relations involved in the Standard-MTS procedure. The results suggest that the emergence of equivalence relations may be compatible with conjoint select and reject conditional control. In Experiment 2, the Detached-MTS procedure succeeds in replicating the emergence of equivalence under exclusive select control but not under exclusive reject control, which conditions the findings of Experiment 1. The sources of control associated with the emergence of equivalence in the standard MTS procedure and some methodological issues of the Detached-MTS procedure are discussed.

Abstract Interprofessional collaboration, or effective, emotionally responsive teaming between professionals, consists of several skill sets including strong communication skills, compassion and shared knowledge, and can enhance client goal attainment. The field of applied behavior analysis has recently focused on improving capacities of interprofessional collaboration and compassion among its professional workforce. Few studies have reported on perceptions of behavior analytic professionals vis a vis these skill sets in clinical settings. The purpose of this study was to describe participant perceptions of interprofessional collaboration and compassion in the context of applied behavior analytic practice. Following IRB approval, a total of 24 applied behavior analysis practitioner participants were recruited in two cohorts, all of whom participated in a 4-month long training-and-coaching intervention on interprofessional, compassion and self-compassion competencies. Qualitative data consisted of 13 recorded transcripts, including a needs-assessment focus group, as well as each training and coaching session, collected to gain understanding in how participants perceived these competencies. Transcripts were independently coded and analyzed via multistep reflexive thematic analysis by a pair of researchers. Ongoing qualitative analysis yielded the following themes: Historical Perspectives: How We Got Here, More Compassionate to Others Than to Self, Old me versus New me. This study revealed perceptions of barriers and supports embedded systemically in behavior analytic training and culture, affecting development of a collaborative and compassionate behavior analytic workforce. This work highlights the importance of qualitative methodology to enhance research in emerging practice areas through analysis of lived experiences.

AbstractUnderstanding factors that influence the efficacy of functional communication training has both practical and conceptual benefits. The current study extended research in this area by exploring data from 95 consecutive applications of functional communication training with extinction across two independent clinics. We selected candidate predictor variables based on conceptual analysis, conducted preliminary exploratory analyses, and then selectively applied quantitative methods that are used in precision medicine to examine their accuracy and predictive utility. Treatment outcomes were better when challenging behavior was maintained by a single function than they were when it was maintained by multiple functions; however, these differences were most apparent among cases with an escape function. We also analyzed within‐session responding to explore the potential influence of unprogrammed establishing operations on decrements in treatment efficacy. Our within‐session measure only distinguished responders from nonresponders when escape was one of the multiple functions. Additional research is needed to validate these findings with an independent sample and to address a number of clinical conceptual issues.
