A statewide evaluation of the Education Now and Babies Later(ENABL) program was conducted to assess its ability to increaseadolescents’ knowledge and beliefs about pregnancy prevention.Using a quasi-experimental research methodology, middle schoolstudents were divided by homerooms into a treatment group (n=900)who got the ENABLE program and a comparison group (n=700) who gotnothing beyond classroom activities as usual (CAU). Participants inboth in ENABL and CAU homerooms completed a pretest and posttestreflecting knowledge and beliefs about pregnancy (PSI: PostponingSexual Involvement); the higher the PSI score, the more accuratethe pregnancy knowledge. Participation was anonymous and student IDnumbers were used to match pretest and posttest. Statistical testsreveal significant differences on posttest scores between ENABL andCAU groups and the ENABL group showed marked improvement frompretest and posttest scores, whereas the CAU group did not.
