Smokers with varying levels of health literacy as assessed by the S-TOFHLA (i.e., inadequate, marginal, adequate) recruited from the community will listen to one of 4 different types of messages emphasizing the health consequences of smoking recorded on a computer in the form of audio scripts (i.e., a human voice pre-recorded on a computer will read each message). Messages written at a 5th to 6th grade reading level will be concurrently presented in written form via a computer monitor and be manipulated in terms of 1) emotionality (i.e., primarily fact- vs. primarily emotion-based), and 2) framing (i.e., gain-framed messages that highlight the potential benefits of quitting smoking vs. loss-framed messages that emphasize the potential costs of failing to quit smoking). Emotionality and framing will be completely crossed to create four different types of messages, 1) factual gain-framed (FGF), 2) factual loss-framed (FLF), 3) emotional gain-framed (EGF), and 4) emotional loss-framed (ELF).
The primary objectives are to:
1. Examine whether main effects emerge for health literacy as assessed by the S-TOFHLA (inadequate, marginal, adequate) and the different message types (fact- vs. emotion-based and gain- vs. loss-framed) on the primary explicit and implicit outcomes: a) intention to quit, and b) implicit and explicit attitudes toward smoking.
2. Examine whether health literacy interacts with the different types of messages (fact-based vs. emotion-based and gain-framed vs. loss-framed) to influence the primary explicit and implicit outcome measures: a) intention to quit smoking, and b) implicit and explicit attitudes toward smoking.
A secondary, exploratory aim is to:
3. Examine potential associations between a) the primary explicit and implicit outcomes, and b) the secondary explicit and implicit outcomes: knowledge, risk perception, attitudes, self-efficacy, message evaluations, implicit fear of disease, and implicit associations between smoking and disease. |
