Detailed Description

The HSPP trial used a group-randomized, matched pair design with the school district as the experimental unit. Of 40 participating school districts, 20 were randomly assigned to the experimental (intervention) condition and 20 were assigned to the control (no HSPP intervention) condition. No restrictions were placed on the health promotion or tobacco use prevention activities of the control districts, thus enabling schools to continue whatever health curricula were normally offered. Main endpoints were daily smoking at 12th grade and 2 years after high school (Plus-2). Study participants (N=8,388) were two consecutive third grade enrollments in each of the 40 school districts. All third graders were followed to endpoint, including those who dropped out of school or otherwise left their school districts. The study achieved a 94% follow-up rate at the Plus-2 endpoint.
The HSPP intervention was a teacher-led, grades 3-10 tobacco use prevention curriculum plus unit-specific teacher training. There were 65 classroom lessons in the HSPP curriculum: 9 lessons in each of grades 3-5, 10 lessons in each of grades 6-7, 8 lessons in grade 8, and 5 lessons in each of grades 9-10, for a total number of 46.75 hours of classroom instruction time in grades 3-10. The HSPP uses an enhanced social influences approach that includes the 15 NCI-endorsed "essential elements" for school-based tobacco prevention and meets the CDC's "best practices" guidelines. The intervention's behavioral components featured skills for identifying and resisting social influences to smoke, correcting erroneous normative perceptions regarding smoking, promoting tobacco-free norms, and building self-efficacy for tobacco-free lifestyle choices. The intervention was developed to be practical for the school setting, emphasizing ease of use by teachers, good fit into school routines and with schools' existing educational objectives, and incorporation of topics/activities that are interesting, engaging and developmentally-appropriate for students.
