ABSTRACT Background Smoking is one of the most dangerous types of addiction in terms of prevalence, morbidity, and mortality due to its nicotine content. For this reason, using a reliable and valid measurement tool is critical to identify and assess the level of smoking accurately. Objective The current study aimed to examine the validity and reliability of the Smoking Scale (SS) used in Turkey and to determine the psychometric properties of this scale. Methods Therefore, the present study consisted of two stages, each of which was conducted with different participants, and a total of 991 participants, both smokers and non-smokers, were included in the sample. Results The results obtained from the SS were found to be valid and reliable (Cronbach’s alpha = .91). The model fit indices obtained by confirmatory factor analysis were found to be within acceptable limits. It was also found that there was a positive and statistically significant relationship between smoking and depression, openness, impulses, and emotion regulation strategies. Conclusions These findings are believed to contribute to future smoking studies, especially in determining the level of addiction.
