Trial Outcomes & Findings for Online Survey in Studying Smoking Attitudes and Behaviors Among Current Smokers (NCT NCT03863795)

NCT ID: NCT03863795

Last Updated: 2021-09-08

Results Overview

Single item assessed intentions to quit smoking, 'Are you considering quitting smoking during the next 6 months?' from the 2014-2015 Tobacco Use Supplement to the Current Population Survey (1=yes, plan to stop within the next 30 days; 2=yes, plan to stop within the next 6 months, but not within 30 days; 3=no, not thinking of quitting in the next 6 months; U.S. Census Bureau, 2016). Response options were reverse scored so that higher scores indicated greater intentions to quit.

Participant Flow

Respondents were directed to complete a 15-20 min online survey on smoking attitudes and behaviors. Participants provided electronic informed consent and then answered two questions to confirm their current smoking status. Current established smokers (smoked at least 100 cigarettes in lifetime and now smoke every day or some days) were eligible. Eligible participants completed survey items assessing smoking characteristics and smoking self-concept.

Measure
Smoking Stigma, Self-Affirmation
Participants viewed a 30-s smoking stigma anti-smoking paid PSA video. Participants ranked 11 values from most to least important. Those in the self-affirmation condition wrote a short paragraph about their most important value (rank 1), describing why it was personally important and how they applied it in daily life.
Smoking Stigma, No-Affirmation Control
Participants viewed a 30-s smoking stigma anti-smoking paid PSA video. Participants ranked 11 values from most to least important. Participants in the no-affirmation control condition wrote a short paragraph about their lowest-ranked value (rank 11), describing why it might be important to someone else.
Non-Stigma Control, Self-Affirmation
Participants viewed a 30-s smoking non-stigma control paid PSA video. Participants ranked 11 values from most to least important. Those in the self-affirmation condition wrote a short paragraph about their most important value (rank 1), describing why it was personally important and how they applied it in daily life.
Non-Stigma Control, No-Affirmation Control
Participants viewed a 30-s smoking non-stigma control paid PSA video. Participants ranked 11 values from most to least important. Participants in the no-affirmation control condition wrote a short paragraph about their lowest-ranked value (rank 11), describing why it might be important to someone else.

Deterministic beliefs regarding smoking behaviors were evaluated using the 18-item self-exempting beliefs scale (Oakes et al., 2004).Response options were 1 (strongly disagree) to 5 (strongly agree). Items were averaged to create a composite measure of self-exempting beliefs with excellent interitem reliability, α = .91.
