| Abstract: | Abstract This article reviews school violence prevention programs that were published between the years of 1990 and 1999. All the interventions fitting inclusion criteria involved being implemented in a school setting, using a control group, and including a quantitative methodology. Effect sizes were calculated for the final sixteen articles that were reviewed in the meta-analysis. A process of inspection was used in order to come up with treatment characteristics most common to each prevention program. Each study was thus described according to six categories: theoretical base, setting, age group, leader training, duration, and random assignment. Four studies resulted with strong effect sizes; however, a regression analysis was not conducted due to inadequate sample size. A review of the literature suggested that program impact could be significantly affected by the use of cognitive-behavioral strategies, multi-setting atmosphere, and primary (elementary school) prevention. In addition, intuitive support (common knowledge in the social science field) indicated that a qualified program leader and longer length of program could also contribute to the influence of a program. Future researchers are encouraged to use a more comprehensive literature review (e.g., past 20 years) in terms of conducting meta-anal-yses in order to provide a larger sample size adequate enough to see the true effects of different intervention components on outcomes (regression analysis; i.e., additive component effects). |
