The effects of noncontingent reinforcement (NCR) without extinction during treatment of problem behavior maintained by social positive reinforcement were evaluated for five individuals diagnosed with autism spectrum disorder. A continuous NCR schedule was gradually thinned to a fixed‐time 5‐min schedule. If problem behavior increased during NCR schedule thinning, a continuous NCR schedule was reinstated and NCR schedule thinning was repeated with differential reinforcement of alternative behavior (DRA) included. Results showed an immediate decrease in all participants’ problem behavior during continuous NCR, and problem behavior maintained at low levels during NCR schedule thinning for three participants. Problem behavior increased and maintained at higher rates during NCR schedule thinning for two other participants; however, the addition of DRA to the intervention resulted in decreased problem behavior and increased mands.  相似文献

Noncontingent reinforcement (NCR) and response blocking are 2 common interventions for problem behavior maintained by automatic reinforcement. We implemented NCR and blocking with 1 boy and found this combined intervention to be effective at decreasing high rates of automatically reinforced pica. With another child, we compared the effects of blocking alone to the combined intervention. With the third child, we compared NCR alone and blocking alone to the combined intervention. Results showed that the combined intervention was effective at reducing automatically reinforced problem behavior while moderate to high levels of item engagement maintained. When evaluated individually, neither NCR nor blocking was sufficient to reduce problem behavior to clinically significant levels.  相似文献

Noncontingent reinforcement (NCR) is typically implemented with extinction (EXT) for destructive behavior reinforced by social consequences and without EXT for destructive behavior reinforced by sensory consequences. Behavioral momentum theory (BMT) predicts that responding will be more persistent, and treatment relapse in the form of response resurgence more likely, when NCR is implemented without EXT due to the greater overall rate of reinforcement associated with this intervention. We used an analogue arrangement to test these predictions of BMT by comparing NCR implemented with and without EXT. For two of three participants, we observed more immediate reductions in responding during NCR without EXT. However, for all participants, NCR without EXT produced greater resurgence than NCR with EXT when we discontinued all reinforcers during an EXT Only phase, although there was variability in response patterns across and within participants. Implications for treatment of destructive behavior using NCR are discussed.  相似文献

We examined the extent to which noncontingent reinforcement (NCR), when used as treatment to reduce problem behavior, might interfere with differential reinforcement contingencies designed to strengthen alternative behavior. After conducting a functional analysis to identify the reinforcers maintaining 2 participants' self-injurious behavior (SIB), we delivered those reinforcers under dense NCR schedules. We delivered the same reinforcers concurrently under differential-reinforcement-of-alternative-behavior (DRA) contingencies in an attempt to strengthen replacement behaviors (mands). Results showed that the NCR plus DRA intervention was associated with a decrease in SIB but little or no increase in appropriate mands. In a subsequent phase, when the NCR schedule was thinned while the DRA schedule remained unchanged, SIB remained low and mands increased. These results suggest that dense NCR schedules may alter establishing operations that result in not only suppression of problem behavior but also interference with the acquisition of appropriate behavior. Thus, the strengthening of socially appropriate behaviors as replacements for problem behavior during NCR interventions might best be achieved if the NCR schedule is first thinned.  相似文献

Having friends who engage in disruptive behavior in childhood may be a risk factor for childhood tobacco experimentation. This study tested the role of friends’ disruptive behavior as a mediator of the effects of a classroom based intervention on children’s tobacco experimentation. 433 Children (52% males) were randomly assigned to the Good Behavior Game (GBG) intervention, a universal preventive intervention targeting disruptive behavior, and facilitating positive prosocial peer interactions. Friends’ disruptive behavior was assessed from age 7–10 years. Participants’ experimentation with tobacco was assessed annually from age 10–13. Reduced rates in tobacco experimentation and friends’ disruptive behavior were found among GBG children, as compared to controls. Support for friends’ disruptive behavior as a mediator in the link between intervention status and tobacco experimentation was found. These results remained after controlling for friends’ and parental smoking status, and child ADHD symptoms. The results support the role of friends’ disruptive behavior in preadolescents’ tobacco experimentation.  相似文献

Four adults diagnosed with moderate to profound mental retardation performed a manual response that was reinforced with food identified from a stimulus preference assessment. During baseline, the response was reinforced on a variable ratio (VR) schedule. Participants were then exposed to noncontingent reinforcement (NCR) plus extinction, and no‐food (i.e., extinction) conditions. A combination multielement and reversal design was used to evaluate intervention effects. For each participant, sessions were conducted both before and after the midday meal during baseline and NCR‐plus‐extinction conditions, thus capitalizing on naturally occurring states of food deprivation and satiation. Results showed that response rates were slightly higher during deprivation sessions than during satiation sessions during NCR‐plus‐extinction and VR schedules for three of the four participants. For three participants, initial NCR schedules did not reduce responding; however, subsequent NCR schedules, which were twice as dense, were effective in reducing response rates. The results are discussed in terms of the development of NCR as a reductive technology and the manipulation of establishing operations applied to the habilitation of individuals with developmental disabilities. The use of a basic experimental preparation as a method of examining decelerative interventions is also addressed. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

We investigated the utilization and efficacy of distraction in reducing the anxious and disruptive behavior of 4 children undergoing dental treatment. During the distraction procedure, the children were shown a poster and told a story about it during dental treatment. They earned a prize if they attended to the poster and story and could correctly answer questions about them following each intervention visit. The children's disruptive behavior was assessed via direct observation, and results were analyzed within a multiple baseline design. The children exhibited high levels of anxious and disruptive behavior across baseline visits, regardless of the length of time in treatment or number of visits. Anxious and disruptive behavior decreased upon introduction of the intervention for all children. This was accompanied by the children meeting the criterion for correct answers on the distraction quiz. However, 2 of the children demonstrated an increase in their anxious and disruptive behavior across intervention visits. Results are discussed in terms of the need to evaluate treatment strategies that promote maintenance as well as initial changes.  相似文献

Parent management training is an evidence-based treatment for disruptive behavior. However, the number of treatment sessions can be high, contributing to high attrition rates. The purpose of this study was to examine post-treatment, 6-month, and 1-year treatment outcomes of the Brief Behavioral Intervention. One hundred twenty children aged 2–6.5 years demonstrating clinically significant disruptive behavior were referred to an outpatient clinic for treatment and participated in the study. Attrition was below reported rates in the literature. Significant decreases in child disruptive behavior and parent stress were found from pre-to-post intervention, and improvements were maintained at follow-ups. Significant pre-to-post intervention teacher reported decreases in behavior were reported.  相似文献

Although there is substantial functional behavioral assessment (FBA) literature suggesting that function-based interventions are effective for improving problem behavior, only a limited number of studies have examined the effectiveness of function-based antecedent versus consequent interventions. Additionally, although there has been a recent increase in the number of studies conducted in the K–12 school setting, only a limited number of studies have included children in the preschool setting. The present study extends existing literature by examining the effectiveness of function-based antecedent versus consequent interventions for reducing problem behavior and increasing appropriately engaged behavior for preschool children without cognitive disabilities. Following an FBA of 4 children, the effectiveness of a function-based antecedent (i.e., noncontingent reinforcement [NCR]) was compared with a function-based consequent (i.e., differential reinforcement of alternative behavior [DRA]) intervention using an alternating treatments design. Results indicated that both function-based NCR and DRA were effective for decreasing problem behavior and increasing appropriately engaged behavior, with function-based NCR being more effective than DRA for 2 of 4 participants.  相似文献

Stereotypy is one of the core diagnostic features of autism spectrum disorder and warrants behavioral intervention when it negatively impacts the person's life. The aim of this study was to evaluate the effectiveness of noncontingent matched stimulation (NCR‐M) compared with response interruption redirection (RIRD) on reducing levels of vocal stereotypy in the natural environment. Interventions were compared using an alternating treatments design followed by generalization and maintenance phases, which utilized lay people as instructors. Results showed that both RIRD and NCR‐M resulted in a reduction in vocal stereotypy for three out of four participants within an educational setting. An increase in appropriate vocalizations was found for two out of four participants for both interventions. These results suggest that both NCR‐M and RIRD were effective in reducing levels of vocal stereotypy, yet their effects on appropriate communication remain undetermined. Social validity scores were obtained following the study, which demonstrated that both interventions were met with approval across a variety of measures.  相似文献

This study examined predictors and outcomes of attendance in two standard components of a multifaceted preventive intervention aimed at children with early-onset disruptive behavior after 3 years of intervention. Mean rate of attendance in the Family Program, but not the Summer School Program, differed by level of child disruptiveness (grouping variable). Although predictors of attendance (SES, single-parent status, child IQ) did not differ across high- and low-disruptive groups, predictors of outcome were moderated by level of child disruptiveness for academic achievement and aggression outcomes, but not for social competence. Higher attendance in the Summer Program was associated with higher child social competence at Year 3 for all children. For academic achievement, higher attendance in the Summer Program was associated with higher scores for mild/moderately disruptive children and lower scores for highly disruptive children in Year 3. Higher attendance in the Family Program was associated with lower aggression scores for mild/moderately disruptive children. Findings highlight the importance of matching intervention components to the assessed or expressed needs of client subgroups.  相似文献

This study provides a direct comparison of differential reinforcement of other behavior (DRO) and differential reinforcement of alternative behavior (DRA). Participants included three children in center-based classrooms referred for functional assessments due to disruptive classroom behavior. Functional assessments included interviews and brief functional analyses. An alternating treatments design was used to evaluate the relative effectiveness of function-based DRO and DRA interventions. Results indicated that both intervention procedures effectively reduced disruptive behavior, but the DRA procedure consistently resulted in greater reductions in disruptive behavior across all participants. Results are discussed in terms of directions for future functional assessment and intervention research as well as implications for applied practice.  相似文献

Prevention studies typically focus on outcome variables such as reductions in problem behavior, rather than targeted factors (e.g., cognitions), or the relation between change in targeted factors and outcomes. Therefore, the current study examined the effect of a targeted prevention program for childhood disruptive behavior on targeted factors (i.e., perspective taking and self-control) and associations between change in targeted factors and outcomes (i.e., aspects of disruptive behavior). The sample consisted of 173 children (Mage?=?10.2 years) who were randomly assigned to an intervention condition (n?=?70) or waitlist control condition (n?=?103). Assessment took place at pre-, post- and follow-up measurements. For ethical considerations, follow-up data was not available for children on the waitlist. Findings revealed a direct intervention effect on self-control. From pre-test to follow-up, children who received the intervention improved in perspective taking and self-control. Moreover, improvements in self-control were associated with and predicted reductions in teacher-reported symptoms of oppositional defiant disorder. No associations were found between changes in perspective taking and disruptive behavior. These findings suggest that self-control may be an important target factor in reducing childhood disruptive behavior in targeted prevention.

We investigated the separate and combined effects of a behavioral intervention and methylphenidate (Ritalin®) on disruptive behavior and task engagement in 3 children with severe to profound mental retardation. The behavioral intervention involved differential reinforcement of appropriate behavior and guided compliance. All 3 children demonstrated decreased disruptive behavior and improved task engagement in response to the behavioral intervention. Two of the 3 children demonstrated similar improvement in response to methylphenidate. Although both interventions were highly effective for these 2 participants, the relative efficacy of the interventions varied between the 2 children. There was no evidence of an additive or synergistic effect of the two interventions, but the high efficacy of each intervention alone limited our ability to detect such effects.  相似文献

Previous research has shown that disruptive behavior can impair students’ academic success (Pierce et al. in Remedial Spec Educ 25:175–188, 2004, https://doi.org/10.1177/07419325040250030501), as well as increase teacher’s stress level (Westling in Remedial Spec Educ 31:48–63, 2010, https://doi.org/10.1177/0741932508327466). The Class Pass Intervention (CPI) is a Tier 2 intervention designed to decrease disruptive behavior and increase academic engagement; however, few studies have evaluated the efficacy of CPI. The purpose of this study was to assess the effects of CPI on disruptive behavior and academic engagement of young students who engage in disruptive behavior. This study used a non-concurrent multiple baseline design to assess experimental control. In the current study, CPI led to a decrease in disruptive behavior and an increase in academic engagement for all three participants and these levels persisted throughout schedule thinning. In addition, results of teacher and student social validity assessments indicated that the intervention was effective and easy to implement and that students preferred the intervention.

Daily Behavior Report Cards (DBRCs) have been found to decrease disruptive behaviors of children with attention-deficit/hyperactivity disorder, intellectual and developmental disorders, and typically developing students. However, although previous studies indicate that peers can assist with the implementation of a variety of interventions (e.g., Check in check out), teachers are often the implementer of DBRCs. In addition, it appears that no studies evaluating DBRCs have included a functional assessment. Thus, the purposes of this study were to assess the effects of a peer-mediated DBRC on disruptive classroom behaviors, determine whether peers could implement their portion of the intervention procedures with high integrity, and assess whether DBRC was effective independent of the functional reinforcer for disruptive behavior. In this study, peer-mediated DBRC led to a decrease in disruptive behavior and an increase in on-task behavior for all three target students who were at risk for EBD. The peer mediators also implemented the DBRC procedures with high integrity. Furthermore, DBRC was effective at suppressing disruptive behavior independent of their presumed functional reinforcer. However, it does appear that different portions of the intervention likely addressed the hypothesized functions of problem behaviors of all three participants.

The current study extends the literature on the assessment and treatment of rumination through the evaluation of a combined reinforcement‐ and punishment‐based intervention. The study included a single participant with a history of rumination maintained by automatic reinforcement, as identified via a functional analysis. Both noncontingent reinforcement (NCR) with preferred edible items and punishment, in the form of a facial screen, were implemented separately to evaluate their independent effects on the occurrence of rumination. The final treatment package included both NCR and punishment procedures. Implementation of the combined treatment resulted in a 96.5% reduction in rumination relative to baseline. Procedural modifications and integrity errors also were evaluated.  相似文献

We evaluated the long-term therapeutic effects of noncontingent reinforcement (NCR). In Experiment 1, NCR effects were examined with 2 participants' arbitrary responses; in Experiment 2, NCR was used as treatment with 3 participants whose self-injurious behavior (SIB) was maintained by automatic reinforcement. In both experiments, NCR consisted of continuous access to a highly preferred leisure item and was implemented initially during 10-min and later during 120-min sessions. Varied reinforcers (leisure items) were subsequently introduced during 120-min sessions to determine if treatment effects might be extended. Finally (Experiment 2 only), NCR was implemented throughout the day in participants' homes. Results of Experiments 1 and 2 showed that reinforcers obtained through object manipulation can compete with those obtained automatically by engaging in SIB during brief NCR sessions. However, data from the 120-min sessions indicated that satiation to a specific leisure item might occur over periods of time more typical of those during which treatment would be implemented. Access to a variety of highly preferred leisure items extended the effectiveness of NCR for some individuals. When NCR was implemented throughout the day (Experiment 2), therapeutic effects were shown to be maintained for up to 1 year.  相似文献

In the current investigation, we evaluated the relative effects of noncontingent reinforcement (NCR), escape extinction, and a combination of NCR and escape extinction as treatment for the feeding problems exhibited by 4 children. For each participant, consumption increased only when escape extinction was implemented, independent of whether NCR was present or absent. These results were consistent with prior research suggesting that positive reinforcement alone is insufficient for increasing consumption, and that escape extinction often is necessary to increase and maintain food acceptance. However, NCR appeared to decrease inappropriate behavior for some participants.  相似文献
