Children born at risk: What's happening in kindergarten?

Many studies examine the development of infants born at risk for medical and developmental problems during the early years of life, but far fewer follow these children into their school years. This project compared high-risk vs. low-risk children in their performance on the WPPSI at pre- and postkindergarten levels. In general, both groups of children demonstrated increases in performance; however, their patterns of performance were different. The high-risk children showed increases predominantly in the Performance areas of the test, whereas the low-risk children demonstrated increases predominantly in the Verbal areas.     

Differential effects of sociocultural variables on special education eligibility categories

The influence of sociocultural factors (ethnicity, socioeconomic status, father absence, and family size) on special education eligibility was examined for three ethnic groups. A multiple regression procedure was used to analyze the data on 300 students referred for evaluation and found to be either not eligible for services or eligible for services as mentally retarded or learning disabled. Results indicated that only socioeconomic status and ethnicity made a significant contribution to the prediction of all three groups. Individually, father absence and family size did not contribute to the prediction of special education eligibility. Results of this study suggest that legislative mandates to control for sociocultural factors in the determination of special education eligibility have been only partially successful.     

Social skills interventions across school settings: Case study reviews of students with mild disabilities

This study investigates the efficacy of a social skills training program with seven mildly handicapped students across three school settings: regular classroom, special education resource room, and recess. It was found that social skills training generated improvement on both pre-post measures and behavior ratings. Improvements were maintained 2 weeks after treatment was discontinued for seven students. All students' performance generalized from resource room to regular classroom settings; only four students' performance generalized to the recess setting.     

Can ability-achievement regression to the mean account for MDT discretionary decisions?

The test scores of 153 referred students who received inconsistent placements according to California's discrepancy criterion, which does not take regression into account (standard score distribution procedure), were reanalyzed using a procedure that accounts for regression. Students involved in these MDT discretionary decisions were placed into one of three groups: ineligible (originally met discrepancy criterion, but not placed), resource class (originally did not meet discrepancy criterion, but placed in a less restrictive pull-out program), and special day class (originally did not meet discrepancy criterion, but placed in a more restrictive, essentially full-time special education class). All of these placements were inconsistent with the nonregressed ability-achievement discrepancy criterion the MDTs used at the time of the IEP meeting. To evaluate how many of these students could be considered to be underachieving when regression is considered, regressed discrepancy scores were computed using the students' scores on the WISC-R and one or more of the following achievement tests: WRAT, PIAT, and W-J. Regression “accounted” for a significant proportion of the inconsistent placements in all three groups: ineligible (25.0%), resource class (31.5%), and special day class (46.9%). Implications for professional practice and public policy are discussed.     

Multimethod behavioral treatment of long-term selective mutism

This single-subject, experimental research design examined the efficacy of treating severe, long-term selective mutism in a 9-year-old male using shaping, multiple re-inforcers, natural consequences, stimulus fading, and mild aversives. Different treatment regimens were implemented in the home and school environments. A multiple baseline design across settings with changing criterion was used to evaluate the home intervention, and an A-B-A design was used for the school intervention. The home intervention resulted in an increase in the number of verbalizations in each setting and prompted generalization to additional settings. The school intervention increased the number of people spoken to, but the results were not maintained at follow-up nor did they generalize outside of the training situation. Possible explanations for the discrepancy in maintenance and generalization data between the two programs are presented.
