Evaluation of a Targeted Intervention Within a Schoolwide System of Behavior Support

A recommended component of comprehensive behavior support in schools is a targeted intervention designed to efficiently and effectively meet the support needs of students who are not responding to preventive schoolwide intervention strategies (Sugai, Horner et al., 2000; Walker et al., 1996). This study provides a fine-grained analysis using a multiple baseline across students design with the targeted intervention as the independent variable, and both classroom problem behavior and academic engagement as dependent variables. The multiple baseline analysis documents a modest functional relationship between implementation of the intervention and reduction in problem behavior. Implications for the design of behavior support in schools and the development of future research are provided.

IDENTIFYING INSTRUCTIONAL TASKS THAT OCCASION PROBLEM BEHAVIORS AND ASSESSING THE EFFECTS OF STUDENT VERSUS TEACHER CHOICE AMONG THESE TASKS

Levels of problem behavior were assessed when 4 students with severe disabilities received instruction on preferred versus nonpreferred tasks and when tasks of each type were chosen by the teacher rather than by the student. In Phase 1, interview and direct observation assessments were conducted to identify relative preferences for academic tasks. In Phase 2, the effects of these lower preference and higher preference tasks on the rate of problem behavior were evaluated using a multielement design. The results showed that lower preference tasks were associated with higher rates of problem behaviors and that students, when given a choice, consistently selected the tasks that had been identified through interview and direct observation as higher preference. In Phase 3, we assessed whether allowing the students to choose between pairs of lower preference tasks or between pairs of higher preference tasks reduced problem behavior relative to a condition in which the teacher selected the same tasks. For 2 of 4 students, the rates of problem behavior were lower when students (rather than the teacher) selected the lower preference activity. Higher preference tasks for 3 students were associated with relatively low rates of problem behavior regardless of whether the student or the teacher selected the task.     

School-Wide Behavioral Support: Starting the Year Off Right

Two years of office referral data are presented in evaluation of a school-wide behavioral support program designed to define, teach, and reward appropriate student behavior in a rural middle school (grades 6, 7, and 8). During 1994-95, the school had 530 students and recorded 2,628 office referrals. The 1995-96 school year began with a full day in which students were taught five school expectations. Throughout the year, students also received rewards for appropriate behavior and office referrals for infractions. Results during 1995-96 document a 42% reduction in office referrals from the previous year. While the evaluation results do not document functional relationship, they suggest an efficient process for evaluating school-wide behavioral support, teaching appropriate behaviors, and changing the overall climate of the school. Implications for future research, and the use of schools as a unit of analysis, are discussed.     

The Student Guided Functional Assessment Interview: An Analysis of Student and Teacher Agreement

Functional assessment strategies are used to guide the treatment of problem behavior with individuals who have severe disabilities. Also, researchers have extended functional assessment applications to individuals with emotional and behavioral disabilities. One such extension is the use of students as informants in the functional assessment process. The present study assessed an interview tool designed to elicit information directly from students regarding their problem behaviors. We examined agreement between students and their teachers. Results showed high agreement on the causes and functions of problem behavior with mixed agreement on support plan recommendations.     

The effects of complexity on the perception of vibrotactile patterns

Vibrotactile patterns were presented to subjects’ left index fmgerpads using the array from the Optacon. A set of simple (one-line) patterns and a set of complex (two-line) patterns were constructed so that they were equally identifiable when presented individually. In Experiment 1, discrimination performance was lower for two-line patterns than for one-line patterns. Communality, the number of lines that two patterns share in common, appeared to be the major factor in reducing discrimination performance for two-line patterns. Experiment 2 measured the time required to identify individual patterns. There was no significant difference in identification times for one- and two-line patterns, suggesting that features within a pattern were processed simultaneously. In the presence of a temporal masking stimulus (Experiment 3), two-line patterns were more difficult to identify than one-line patterns, but reaction times were similar for the two sets of patterns. The results suggest that varying complexity affects perception of patterns at later stages of processing.     

SOCIAL INTERACTIONS IN THREE SUPPORTED EMPLOYMENT OPTIONS: A COMPARATIVE ANALYSIS

Controversy exists over the benefits that workers with severe disabilities accrue under different supported employment options. This study focused upon one benefit of supported employment: social integration. Direct observation procedures were used to assess the social interactions of 37 adults with severe disabilities in 18 employment programs representing three different supported employment contexts (individual, enclave, and work crew). Results indicated that workers employed in individual and enclave programs had significantly more contact with nondisabled persons than did members of work crews. No differences were detected in the social contact rate between disabled and nondisabled workers in individual versus enclave sites. Furthermore, few differences in type of interactions across the three different work options were revealed. Results suggest that both individual and enclave models are capable of facilitating social integration. However, characteristics of specific job sites, more so than the employment model per se, may determine whether a particular employment setting is conducive to social integration.     

THE EFFECTS OF RESPONSE EFFICIENCY ON FUNCTIONALLY EQUIVALENT COMPETING BEHAVIORS

Three experiments addressed the role of response efficiency in the application of functional equivalence training. Functional equivalence training includes conducting a functional assessment of the problem behavior. Variables that predict and maintain the problem behavior are defined, and socially appropriate, functionally equivalent skills are identified and taught. The logic is that if the learner has a socially appropriate way to achieve the same function, he or she will be less likely to use problem behaviors. This study examined the role of response efficiency in functional equivalence training. Response efficiency was examined in terms of three variables: (a) physical effort, (b) schedule of reinforcement, and (c) the time delay between presentation of the discriminative stimulus and reinforcer delivery. Each of the three experiments involved a person who performed a set of problem behaviors and a functional assessment of the problem behaviors. A socially appropriate alternative response was taught, but this new response was less efficient than the problem behavior on one of the efficiency variables (effort, schedule, delay in time). The new behaviors did not compete successfully with the problem behaviors until a new, more efficient, alternative behavior was taught. These results are discussed in terms of our understanding of response covariation and the need in applied contexts to include response efficiency in any functional analysis assessment.     

The effects of complexity on the perception of vibrotactile patterns.

Vibrotactile patterns were presented to subjects' left index fingerpads using the array from the Optacon. A set of simple (one-line) patterns and a set of complex (two-line) patterns were constructed so that they were equally identifiable when presented individually. In Experiment 1, discrimination performance was lower for two-line patterns than for one-line patterns. Communality, the number of lines that two patterns share in common, appeared to be the major factor in reducing discrimination performance for two-line patterns. Experiment 2 measured the time required to identify individual patterns. There was no significant difference in identification times for one- and two-line patterns, suggesting that features within a pattern were processed simultaneously. In the presence of a temporal masking stimulus (Experiment 3), two-line patterns were more difficult to identify than one-line patterns, but reaction times were similar for the two sets of patterns. The results suggest that varying complexity affects perception of patterns at later stages of processing.
