Reliability and validity of the Smoking and Women Questionnaire among three ethnic groups.

Abstract

Cigarette smoking among women continues to be a major health risk to the smoker and to those around her. Programs aimed at stopping and maintaining smoking cessation have had very limited success due in part to the failure to individualize smoking cessation programs based on specific characteristics of the smoker. This study presents reliability and validity of a 14-item questionnaire developed to determine the readiness of women from three ethnic groups (non-Hispanic white, black American, and Hispanic American) to stop smoking. The Smoking and Women Questionnaire (SWQ) consists of items representative of core elements conceptualized in the Smoking/Ex-smoking Model for Women. The core factors are: beliefs/attitudes toward smoking, sociability, stress, coping, self-efficacy, motivation, nicotine dependence, and support. The SWQ was completed by both smoking and nonsmoking non-Hispanic white (N = 233), smoking and nonsmoking black American (N = 70), and smoking and nonsmoking Hispanic American (N = 73) women. The test-retest correlation coefficient over a one- to three-week period (N = 53) was .84. Cronbach alphas for whites, blacks, Hispanics, and combined groups were .81, .85, .84 and .83, respectively. Content validity was shown by experts who agreed that the core elements were represented in the SWQ. Construct validity was shown for ethnic groups separately and combined in that smokers had significantly lower SWQ scores than nonsmokers. Items representative of the core elements were rated by smokers in a similar manner irrespective of ethnicity, suggesting similar attitudes and behaviors toward smoking. Further research is needed to determine if the SWQ can predict readiness of women to stop smoking and serve as a basis for developing individualized smoking cessation programs. Implications for smoking cessation programs are reviewed.
