title: [Measure methods of tobacco abstinence according to recommendations--own and Canadian research finding].
abstract: BACKGROUND
  Tobacco abstinence measure in smoking cessation interventions is the key methodological issue. We can find different methods of short- and long-term tobacco abstinence measure and outcome comparisons in the scientific papers. The methodological guidelines have been provided by recommendations of the Society of Research on Nicotine and Tobacco 2001, 2002, 2003 and the Society for the Study of Addiction 2005.
  
  
  OBJECTIVE
  Preparation of the rules of tobacco abstinence rates calculation from extremely conservative to extremely liberal ones according to recommendations and comparison of own research and Tom Baker Cancer Centre Study TBC Calgary, Canada outcomes.
  
  
  METHODS
  The own empirical data gathered in 2001-2007 for 627 participants of group-based smoking cessation program with follow-up in 2008-2009 and the TBC data gathered in 1986-1990 for 971 participants of group behavior intervention with follow-up in 1995 were used in the analyses.
  
  
  RESULTS
  Tobacco abstinence rates were differentiated depending on an observation period (range from 12% do 17%) and the methodological approach from extremely conservative to liberal one (range from 17% to 30%).
  
  
  CONCLUSIONS
  To improve the scientific quality of long-term outcomes of smoking cessation interventions and comparisons the list of ten key methodological questions were prepared for researcher to answer them on the conceptualization stage of the project. Further research regarding smoking cessation interventions using methodological guidelines of the SRNT Work Groups recommendations are needed.
