The presented study investigated the role that several variables, viewed separately, may play in terms of levels of nicotine dependence. Sixty participants were engaged in the study. Twenty- four were non-smokers the remaining thirty six were smokers, with different levels of addiction, from strong to very weak. The above specified sample of participants, completed few questionnaires: Cohen’s (Cohen, Kamarck and Mermelstein, 1983) stress perception scale, Goldberg’s (1993) depression questionnaire, and Barratt’s (Patton, Stanford and Barratt, 1985) impulsivity scale. Additionally smokers received Fagerstrom’s (Heatherton, Kozlowski, Frecker and Fagerström, 1991) nicotine dependence scale to fill in on the first place, to measure their level of addiction. The results were measured using multiple regression which would check the relationship between dependent variable- smoking and all three independent variables (stress perception, impulsivity and depression). The results were surprisingly only partially significant. Findings supported the hypothesis that stress perception as well as impulsivity could be good nicotine dependence predictors. The age was, as expected found non- significant predictor. However results concerning depression did not support findings from other studies. Depression therefore was found not to be mediator significantly influencing smoking addiction. Those several predictors and the strength of their mediation on nicotine dependence, as well as the implications of those findings are presented in more details below.
Studies concerning all types of addictions, and reasons for their more often occurrences seem to be increasing in number nowadays. There were many motives found by researchers, which would reasonably, in a sense, explain smoking dependence. Russell, Peto, and Patel (1974) found that people... [continues]
