Background
  • Valid measurement is essential to science
  • Comprehensive validation studies are lacking,
    for most withdrawal scales
  • Available scales were developed in UK or USA,
    and may not reflect situation in other
    countries
  • Some widely used scales are not recent -
    Minnesota Withdrawal Scale (Hughes) 1986 -
    Shiffman-Jarvik 1976

To develop and assess the validity of a new,
self-administered scale measuring cigarette
withdrawal symptoms, using state-of-the-art
psychometric methods

Qualitative survey methods
  • Questionnaires sent out by mail to a
    representative population sample in Geneva,
    n2,000
  • "Please describe how a smoker feels when he
    is deprived of nicotine"
  • 404 answers from smokers and ex-smokers
