The baseline survey used published items to assess (in the order asked) general health, smoking patterns and quitting history, children and children's health, household composition and smoking status, weight, alcohol consumption, depressive symptoms, social support, perceived stress, and demographic characteristics. General health questions covered perceived health status, current or past medical conditions, whether the woman had a regular health care provider, if she had visited the clinician in the past year, and, if so, whether the clinician had advised her to quit smoking. Smoking patterns and quitting history questions assessed the amount smoked, the time to the first cigarette of the day as a proxy measure of addiction, the number of serious attempts to quit and the longest prior period of abstinence, advice to quit from any health care provider in the prior year, use of pharmacological and/or behavioral treatments for quitting, stage of readiness to quit, the level of desire to quit, and reasons for quitting. Questions about children ascertained current pregnancies, the number and ages of children, health problems of children in the past 3 months, children's visits to physicians in the past 3 months for respiratory-related conditions, and the level of concern and behavior regarding exposure of the child to secondhand smoke. Household composition assessed whether the woman lived with a husband or partner, the number of adults and children currently living in her household, and the number of adults and children living in the household who smoked. Weight questions assessed the woman's perception of being overweight, underweight, or about average, the level of concern regarding a weight gain of 5 pounds, current dieting status, height, and weight. Alcohol questions assessed use of alcohol in the past 30 days, average daily consumption, driving after consuming more than 2 drinks, and the number of binge drinking episodes (defined as 5 or more drinks on a single occasion). A 6-item measure from the Hopkins Symptom Checklist10 assessed depressive symptoms. Stress was assessed using a 4-item Perceived Stress Scale11; social support was assessed using a 6-item Interpersonal Support Evaluation List.12 Demographic information included race/ethnicity (respondents could check any of 5 categories, plus an "other" category, that applied to them), marital status, employment, education, and household income. Completion of the survey took 10 to 15 minutes.
