Previous studies have focused on whether a trial-based functional analysis (FA) yields the same outcomes as more traditional FAs, and whether interventions based on trial-based FAs can reduce socially maintained problem behavior. We included a full range of behavior functions and taught 3 teachers to conduct a trial-based FA with 3 boys with developmental and intellectual disabilities who engaged in problem behavior. Based on the results of the trial-based FAs, we developed and conducted 5 function-based interventions, using differential reinforcement of an alternative behavior and extinction in all but 1 case. In the remaining case, we used noncontingent reinforcement. All interventions led to reductions in problem behavior and increases in alternative behavior.

Failure to reinforce appropriate behavior could result in resurgence of previously extinguished problem behavior and degradation of previously effective treatments such as differential reinforcement of alternative behavior (DRA). We analyzed arbitrary responses (i.e., switch flipping) exhibited by 3 adults with developmental disabilities to compare the effect of a traditional DRA intervention against the effect of a serial DRA intervention on the magnitude of target response resurgence using a 2-component multiple schedule. The target response served as an analogue to problem behavior, and alternative responses served as analogues to socially appropriate alternative responses. In all cases, the percentage of total responding allocated toward target response resurgence was less in the serial DRA component than in the traditional DRA component. Furthermore, we observed both reversion and recency for 2 of 3 subjects. Our data provide preliminary evidence suggesting that serial DRA may produce more durable and desirable outcomes than traditional DRA.

Despite years of research, methodological and practical obstacles make it difficult to conclude whether policies aimed at improving schools and communities are effective for improving youth outcomes. To complement existing work, we assess research on the educational and social outcomes for comparable youth who change school and neighborhood settings through unique housing policy and school voucher programs. Research shows that housing programs have helped poor families move to much safer, less disadvantaged, and less segregated neighborhoods. Some housing programs have also provided early educational benefits for young people who relocated to less poor and less segregated neighborhoods, but these gains were not maintained in the long run. School voucher programs have helped disadvantaged youth attend higher-performing private schools in less segregated environments with more middle-class peers. Although some voucher programs have shown small positive effects, the results of others are less certain owing to methodological weaknesses. Future research should directly examine families' selection processes and be cautious with quantitative research that uses naturally occurring variation to model the effects of potential social programs. Researchers should also recognize the family processes that interact with social policy to determine how youth development can be improved, alongside the structural and political processes that condition how programs work at a larger scale. 457 Annu.

Functional communication training (FCT) is commonly used to eliminate problem behavior. Not surprisingly, the efficacy of the intervention depends on fidelity to programmed procedures. For instance, problem behavior is likely to resurge if caregivers fail to reinforce mands during the maintenance stages of FCT. Despite this, recent translational work on arbitrary human responses suggests that incorporating multiple‐mand instruction into a serial‐training format may increase the probability of a recency effect, and a reversion of response resurgence (both desirable outcomes when mands are the most recently reinforced responses prior to extinction). Although promising, this effect has not been replicated with socially significant human behavior. Thus, we compared the relative effect of traditional FCT with that of serial FCT on the resurgence of the problem behavior, and mands, of 2 children. In contrast to previous research, we observed primacy effects for both subjects (i.e., the magnitude of the resurgence of problem behavior was greater than it was for any subsequently trained mand), and mand resurgence never occurred for one subject. Notwithstanding these limitations, the percentage of total responding allocated toward the resurgence of problem behavior was less in the serial FCT component relative to the traditional FCT component, and we observed a reversion of response resurgence for one subject.

Functional behavioral assessments are commonly used in school settings to assess and develop interventions for problem behavior. The trial-based functional analysis is an approach that teachers can use in their classrooms to identify the function of problem behavior. The current study evaluates the effectiveness of a modified pyramidal training procedure in which special education program coordinators were taught to conduct trial-based functional analyses and then provided support to special education teachers who were taught to conduct trial-based functional analyses and to calculate, graph, and analyze data. After training, the teachers conducted the trial-based functional analysis with over 85% accuracy and demonstrated criterion performance analyzing and graphing data. Accuracy was maintained during in-situ generalization probes conducted with two of the teachers.
