Screening CHIR99021 mw continued until the selected sample was approximately 33% normal weight, 33% overweight, and 33% obese. Participants meeting initial screening criteria were invited to participate. Procedures Interested and initially eligible callers were transferred to a specially trained quit coach who provided informed verbal consent and conducted a baseline survey. Participants were then provided with standard quitline services. A total of 595 eligible participants agreed to participate in the study, comprising 15.5%, 14.3%, 29.9%, 8%, and 32.3% of quitline users from Georgia, Louisiana, Maryland, South Carolina, and Texas, respectively. Assessments Demographics Age, sex, educational attainment, race and ethnicity, height, and weight were obtained by self-report.

Body Mass Index (BMI; weight in kg/height in m2) was calculated. Tobacco Use Number of years of tobacco use and the frequency of current smoking was determined by asking if the caller smoked cigarettes every day or some days. The number of previous quit attempts and current number of cigarettes smoked per day was also ascertained. Smoking-Specific Weight Concerns Several smoking-related weight concerns measures were used. First, participants answered a six-item questionnaire designed to assess cessation specific weight concerns and a separate six-item questionnaire assessing self-efficacy for weight management after quitting smoking (Borrelli & Mermelstein, 1998). Both the weight self-efficacy and weight concerns scales range from 0 to 10. In addition, based on previous work on the treatment of weight-concerned smokers (Levine et al.

, 2010; Perkins, et al., 2001), individuals answered the following two questions using a scale of 0�C100 (where 0 = not at all and 100 = extremely): 1) ��How concerned are you about gaining weight after quitting?�� and 2) ��How concerned would you be if quitting smoking caused you to permanently gain 10 pounds (4.54 kg)?�� Finally, callers were asked about the amount of weight they expected to gain upon successfully quitting smoking and about the amount of postcessation weight gain they would be willing to accept as well as the amount of maximum weight gain in any previous quit attempt. Motivation to Quit Smoking Participants rated their motivation on a scale from 1 (not strong at all) to 10 (extremely strong), in response to the question ��How strong is your motivation to quit?�� Depressive Symptoms Two depressive symptoms were queried.

Participants were asked how often they experienced anhedonia or felt ��down, depressed or hopeless�� over the past two weeks. Response options were ��not at all, several days and more Drug_discovery than half the days.�� Participants who responded ��more than half the days�� to at least one option were rated positive for depressive symptoms.
