Predictors of attempts to stop smoking and their success in adult general population samples: a systematic review

To identify the predictors of attempts to stop smoking and the predictors of quit attempt success in adult general population samples.

We performed an electronic search of EMBASE, Pubmed, Web of Science, PsychINFO and the Cochrane Tobacco Addiction Group specialized register for articles that examined, in prospective adult general population samples, predictors of quit attempts and the success of quit attempts. Experts were contacted for knowledge of other relevant studies. Eight studies met the inclusion criteria and results were extracted independently by two researchers.
