Validating School Social Work: An Evaluation of a Cognitive-Behavioral Approach to Reduce School Violence

Whitfield’s 1999 article aimed to evaluate a cognitive-behavioral approach to reducing school violence. Specifically, the study aimed to test the effectiveness of this approach on reducing violent behavior and increasing academic performance among high-risk students in a large urban school district.

The sample for this study consisted of six high-risk students who were identified by school administrators as having a history of violent behavior. The sample included four male and two female students, all of whom were in grades 9 through 12. The students were selected based on their prior involvement in violent incidents, poor academic performance, and attendance problems.

The dependent variables studied were academic performance and violent behavior. Academic performance was measured using the students’ grades, and violent behavior was measured using incident reports from the school’s security staff. These variables were operationalized by calculating the students’ grade point averages and recording the number of violent incidents reported during the study period.

A single-subject design was used in this study to evaluate the effectiveness of the cognitive-behavioral approach. The strengths of a single-subject design include the ability to measure individual behavior changes over time, the ability to control for extraneous variables, and the ability to determine causality. In this study, a single-subject design was appropriate because the sample consisted of only six participants, and each participant received individualized treatment.

The key findings of the study indicated that the cognitive-behavioral approach was effective in reducing violent behavior and improving academic performance among high-risk students. The data analysis showed a significant decrease in the number of violent incidents reported and a significant increase in grade point averages for all six participants.

While the study’s findings were promising, several limitations of a single-subject design must be considered when critiquing the results. First, the sample size was small, which limits the generalizability of the findings to other populations. Second, the study lacked a control group, which makes it difficult to determine whether the changes observed were a result of the treatment or other factors. Finally, the study did not address the long-term effects of the cognitive-behavioral approach on students’ behavior and academic performance.
