About this study

The Hutchinson Smoking Prevention Project is a 16-year, group-randomized trial to determine the extent to which a school-based (grades 3-10), theory-based, social-influences tobacco use prevention intervention can deter youth tobacco use throughout and beyond high school.

Read the detailed description

Cigarette smoking remains the number one cause of preventable premature death in the U.S., annually killing more than 400,000 Americans. Without reversal of adolescent smoking trends, five million of today's youth will die prematurely of smoking-related illnesses. The 16-year Hutchinson Smoking Prevention Project (HSPP) was conducted in 1984-1999 to (1) address challenges of trial design and execution in school-based smoking prevention by developing the most rigorous school-based randomized trial possible, and (2) use the trial to answer the scientific questions, "To what extent can a theory-based, social-influences smoking prevention intervention spanning elementary, middle and high school grades reduce smoking among youth at 12th grade and two years post-high-school?"

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Smoking Daily at 12th Grade

    Response "1 to 3 cigarettes per day," "4 to 10 cigarettes per day," "11 to 20 cigarettes per day," or "More than 20 cigarettes per day" to the Item "How often do you currently smoke cigarettes?"

    Measured: 12th grade

  2. Whether or Not Smoking Daily at 2 Years After High School

    Response (from the 2-years-after-high school questionnaire) "Daily: 1 to 10 cigarettes a day," "Daily: 11 to 20 cigarettes a day," "Daily: more than a pack a day" to the Item "How often do you currently smoke cigarettes?"

    Measured: 2 years after high school

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Nov 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants Smoking Daily at 12th Grade (time frame: 12th grade). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00115869, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
