Literacy and Smoking Risk Communications
NCT00684437 · View on ClinicalTrials.gov ↗
Study Summary
Objectives: 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 an

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00684437
The ClinicalTrials.gov registry entry for NCT00684437 describes a study currently listed as active not recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 494 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is M.D. Anderson Cancer Center, which has 2,992 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Smoking appearing as the primary indexed condition, and to 2 interventions — of which Focus Group is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00684437 reports 1 study location spanning 1 distinct geographic area — top geographies include Texas. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
