OBJECTIVES: The aim of this study was to determine the reliability and validity of the Smoker Complaint Scale for the Turkish population. METHODS: The research was conducted in the university students. For pretest study forty students were chosen as a sampling group. After the assessment of the results, the Smoker Complaint Scale was applied to 250 students who quit smoking. Of the students are 54% female and 46% male. The original instrument was translated into Turkish and then translated back into English by two independent translators. For psychometric measures, a small sample was used to check the initial comprehension and factibility. Cronbach’s Alfa was used to assess reliability and factor analysis to assess dimensionality. The EuroQol-5D was used for concurrent validity. RESULTS: The internal consistency coefficient (Cronbach's alpha) of SCS was 0.912. Factor analysis of the scale revealed that it was composed of 5 factors with Eigenvalues >1.0, accounting for 77.9% of the total variance. All the items of the Turkish SCS had a factor load ranging from 0.587 to 0.886 and they all belonged to 5 factors. There was a strong relationship between SCS and EuroQol 5D (r= between 0.46.- 0.76). CONCLUSIONS: The research suggests that the validity and reliability of the Turkish SCS are satisfactory and that it can be used in Turkey.
