Eat for Life examines two constructs of tailoring within a print-based fruit and vegetable intervention for African American adults. Study 1 explores the use of motivational predisposition to tailor health behavior content, while Study 2 explores the use of cultural factors and ethnic identity for tailoring its' messages. Both studies use tailored print media, in the form of three 8 to 12 page newsletters, delivered to participants' homes.
Aim 1. Develop conceptually distinct intervention messages for modifying fruit and vegetable intake for African Americans, from domains of cultural tailoring (surface structure, deep structure, and culturally-based) and domains of motivation (extrinsic, intrinsic, and values-based).
Aim 2. Using a fractional factorial design, identify the most powerful messages and/or combination of messages that impact fruit and vegetable intake at six month follow-up.
Aim 3. Identify person characteristics that modify the impact of these messages (e.g., ethnic identity and motivational predisposition).
Aim 1. Develop an individually-tailored, print fruit and vegetable intervention using conceptually distinct cultural and motivational messages.
Aim 2. Explore the optimal "dose" of tailored cultural and motivational messages.
Aim 3. Explore the optimal "source" the tailored messages, such as peer, professional, or religious leader.
Aim 4. Explore possible person characteristics that may interact with message, dose and source factors.
