All subjects were sentenced in 1985. Multiple regression analysis was used to determine the relative predictive power of the variables for sentencing. Although type of previous court disposition and current offense were powerful factors, the inclusion of the social-inquiry-report recommendations as an additional variable greatly improved prediction of the court outcome. The study cautions that the context in which juvenile court decisions are made as influenced by changes in local crime patterns, variations in operational procedure, and differences in the sentencing objectives of individual magistrates are all factors which may account for variation within the predictive model based in the factors examined in this study. 5 tables and 7 references.
