Assessment of behavior change in a fragile X syndrome male treated with folic acid.There is limited empirical evidence regarding teachers' decisions about interventions to change the behavior of students with emotional and behavioral problems. This study examined whether teachers considered such salient student characteristics as age and type of problem behavior when selecting interventions that they perceived as likely to be effective in managing students' behavior. The results suggest that both regular and special education teachers take student characteristics into consideration when making such intervention choices.Research has shown that teachers differentiate among specific student behaviors when making labeling decisions. Previous studies have indicated also that labeling decisions are influenced negatively by the presence of labels such as "emotionally disturbed" or "behaviorally disordered" in referring information, and that the label-related biasing effects are compounded by bias related to sex, socioeconomic status, and ethnic group identification (Smith, Wood, & Grimes, 1988). Researchers have attempted to clarify the mechanisms governing biasing effects. Baer, Goodall, and Brown (1983) and Algozzine (1979) have shown that teachers view certain behaviors as more serious and disturbing than others. Baer et al. (1983) found that physically dangerous behaviors were considered the most serious problems in school settings, followed, in order, by disruptions to learning, challenges to the teacher's authority, violation of social standards, violation of the rights of others, and illegal behaviors. Algozzine (1979) found that socially defiant behaviors were rated as more disturbing than socially immature, socially delinquent, or physically disturbing behaviors. The student peer group does not always share teachers' views of the seriousness of problem behaviors. Mullen and Wood (1 986) found that junior high school students considered many problem behaviors on the checklist used by Algozzine to be less disturbing than did their teachers and differed in their overall rankings of the disturbingness of behaviors. To what extent do these perceived differences in the seriousness of problem behaviors influence teacher decisions about the acceptability and effectiveness of different interventions?Algozzine, Ysseldyke, Christenson, and Thurlow (1983) obtained teachers' intervention choices for students characterized by either immature or unmanageable socially defiant behavior. They found that, for their sample, "student characteristics (e.g., immature vs. unmanageable) had no effects on teachers' preferred interventions," and conRequests for reprints should be sent to Frank H.
