Tailoring Depth

About

This project runs in conjunction with Phase I of Project Quit. While Project Quit focuses on tailoring messages based on a variety of theoretical constructs, this study focuses on tailoring those messages on a deeper level. Depth of tailoring is another potentially active ingredient in tailoring and refers to the level of detail of tailoring and the extent of the connections made among theory-based constructs.

Aims

Aim 1. Compare the effectiveness of low- versus high-depth tailored websites in achieving a 7-day abstinence measured at 6-month follow-up.

Aim 2. Compare the effectiveness of low- versus high-depth tailored websites on smoking cessation across baseline characteristics of self-efficacy, motivation, gender, age, income, and education.

Participants

1,848 participants from three HMOs: Group Health (Seattle, WA), HealthPartners (Minneapolis, MN) and the Health Alliance Plan (Detroit, MI).
