UNLABELLED: Nurses in hospitals are not active in smoking cessation because of certain beliefs and attitudes. Beliefs and attitudes must be measured for changing practice in quitting smoking. The objective is to develop and validate a questionnaire on smoking cessation practices of nurses in hospitals. METHODOLOGY: A methodological study was conducted to construct a questionnaire (n = 118) according to the theory of planned behaviour, to validate by four experts, for reliability and validation of instruments constructs (n = 38; n = 29; n = 157). RESULTS: An initial questionnaire on practices in smoking cessation was built according to the beliefs of a convenience sample of 118 nurses. Validation of experts was conducted, and the questionnaire obtained an index of content validation (ICV) of 0.94. Subsequently, after two convenience samples (n = 38; n = 29) and a random sample (n = 157), the questionnaire obtained reliability, measured by Cronbach's alpha ranging in 0.697 and 0.93 1. Finally, moderately high correlations (0.406 to 0.569) were obtained between concepts. CONCLUSION: A reliable and valid questionnaire in French is available to measure smoking cessation practices.
