Effective Communication Strategies for Promoting Smoking Cessation in Carpenters

Specific Aim 1: Develop targeted health messages based on audience segmentation to encourage
smokers to enroll in a comprehensive union-sponsored smoking cessation program.

We will craft six specific health messages that appeal to four different audience segments:
workers under 30 years old without children, workers under 30 with children, workers 30
years old or older without children, and workers 30 or older with children.

Specific Aim 2: Conduct a randomized controlled trial of targeted messaging based on
audience segmentation versus standard smoking cessation messaging.

After conducting baseline surveys with union carpenters and floor layers, we will randomize
current smokers (smoked within the last 30 days) into either the intervention or control

- Control subjects will receive one standard mailing informing them about the free
smoking cessation program available to union members.

- Intervention subjects will receive the standard mailing in addition to six targeted
smoking cessation messages delivered monthly by mail to their homes. Messages will be
specific to one of four audience segments determined by age and parental status. In
addition to a segment-specific anti-smoking message, each mailing will have contact
information for the union smoking cessation program. Intervention subjects who
consented to text messaging will also receive one booster text message each month with
a shortened targeted message.

Inclusion Criteria:

- Current smoker (smoked cigarettes within the last 30 days)

- Eligible for union health benefits
