Functional communication training (FCT) is one of the most commonly prescribed interventions for the treatment of severe destructive behavior exhibited by individuals with intellectual disabilities. Although highly effective, FCT has been shown to fail in some cases when treatment is introduced into the child's typical environment. Basic and translational research on renewal provides a model for studying the relapse of destructive behavior following successful response to treatment in clinic settings using FCT. In the present study, we evaluated whether relapse of destructive behavior could be attributed to the discriminative control of the home context, which was historically correlated with reinforcement for destructive behavior. We implemented baseline contingencies in the home setting with caregivers acting as interventionists (i.e., Context A). We then implemented FCT in a treatment clinic with trained therapists (i.e., Context B). Finally, we introduced FCT in the home setting with caregivers implementing the treatment procedures (i.e., return to Context A). For three of four participants we observed the relapse of destructive behavior consistent with operant renewal. We discuss the implications of these findings with respect to strategies designed to promote generalization of FCT across settings during the treatment of severe destructive behavior.
Concepts from behavioral momentum theory, along with some empirical findings, suggest that the rate of baseline reinforcement may contribute to the relapse of severe destructive behavior. With seven children who engaged in destructive behavior, we tested this hypothesis in the context of functional communication training by comparing the effects of different baseline reinforcement rates on resurgence during a treatment challenge (i.e., extinction). We observed convincing resurgence of destructive behavior in four of seven participants, and we observed more resurgence in the condition associated with high-rate baseline reinforcement (i.e., variable-interval 2 s in Study 1 or fixed-ratio 1 in Study 2) compared to a low-rate baseline reinforcement condition. We discuss the implications of these results relative to schedules of reinforcement in the treatment of destructive behavior and strategies to mitigate resurgence in clinical settings.
ABA renewal is a model of treatment relapse that describes the recurrence of severe problem behavior when behavior learned in one context (e.g., home; A) and treated in a separate context (e.g., clinic; B) reemerges when the original context is reintroduced (A). However, in the typical environment and during the usual course of treatment for severe problem behavior, the target behavior is exposed to the baseline context periodically (e.g., the child returns home after several hours in a clinic setting). Due to the difficulty of studying what effect this may have on treatment relapse during ABA renewal in a strictly applied investigation, we developed a human-laboratory translation to study renewal in a nonsequential manner. Using undergraduate students as subjects, we directly compared levels of recurrence using the standard ABA renewal procedure and a modified nonsequential ACA procedure, one modeled from the typical course of treatment for problem behavior. Both methods produced renewal at comparable levels, and patterns during nonsequential ACA renewal were similar to those during sequential ABA renewal. We discuss the implications of these findings in the framework of treatment for severe problem behavior.
Functional analyses sometimes do not identify momentary fluctuations in the function of destructive behavior (Bowman, Fisher, Thompson, & Piazza, 1997). In such cases, individuals may mand for the reinforcer that is currently most preferred and display destructive behavior if that mand goes unreinforced. In this study, we conducted a mand analysis to test whether destructive behavior functioned as a precurrent response that increased reinforcement for the participant's mands. We then evaluated a treatment that matched this function of destructive behavior by providing differential or time‐based reinforcement of participant mands in accordance with multiple or chained schedules with reinforcement‐schedule thinning. Decreases in destructive behavior averaged 97.4% across cases. We discuss these results relative to the importance of matching treatments for destructive behavior to operant functions for both traditional and idiosyncratic functions of destructive behavior.
PurposeThis paper aims to examine contracts in public jurisdictions to compare academic theories related to outsourcing risks and risk management strategies to current practice in order to extend and refine theory concerning what risk management strategies can, or should, be included in outsourcing contracts.Design/methodology/approachAn automated content analysis tool is used to rigorously compare contract documents in two public jurisdictions to a comprehensive outsourcing risk framework from previous research.FindingsThe findings indicate that although IS outsourcing risk factors are widely acknowledged in the literature, they are not fully specified in the outsourcing contracts that are implemented in some public organizations. This research surfaces some of the differences in the techniques implemented through actual contracts to manage the risks inherent in IS outsourcing, including some strategies not previously identified in the literature. Also, not all risks need to be addressed in the contract to have a successful outsourcing engagement.Practical implicationsThe improved framework for thinking about risk management strategies in the contracting process shown within the paper can provide important ideas and insights for managers contemplating or renewing outsourcing engagements.Originality/valueThis paper uses content analysis to rigorously compare academic theory to actual practice to extend theory. Specifically, it discovers several risk management strategies that have not been presented in previous research.
