Objectives: To assess the psychometric capability of the Fagerström test for nicotine dependence in a sample comprising college students in Arequipa. Materials and methods: We worked using a sample comprising students enrolled in a private college in Arequipa. All subjects participated in a voluntary fashion, and they were selected using a quota sampling technique. The sample size was calculated using probabilistic methods and a 95% confidence level. The six-item version of the Fagerström test for nicotine dependence was administered. Results: Four-hundred and sixty-four students participated, 59.48% wee female, and the mean age was 20 ± 2.29 years. The one-dimensional nature of the instrument was determined using adjusted goodness of fit indexes which were set in place with a confirmatory factorial analysis. Reliability of the test was 0.86 according to Cronbach's alpha test, and it was 0.65 using Mc Donald's Omega test. Conclusion: The test complies with acceptable validity and reliability criteria, and it allows to identify students with dependence to nicotine, particularly those who achieved 2.5 or higher scores.
