Objectives: this study aims to assess the validity and reliability of the persian version of simons and gaher `s distress tolerance scale(dts) by administering it to nicotine dependent students of tehran university. method:in a descriptive cross-sectional study, 317 nicotine dependent students of tehran university who were selected ,using available sampling method, completed dts, coping with stress- revised(cs-r), positive and negative affect scales(panas) and fagerstrom test for nicotine dependence(ftnd). data were analyzed using descriptive statistic methods and correlation coefficient. results: the alpha coefficients for tolerance, absorption, appraisal and regulation subscales were 0.75, 0.77, 0.70 and 0.75, respectively. the test-retest correlation coefficients with two months interval for tolerance, absorption, appraisal and regulation subscales and the total scale were 0.71, 0.69, 0.77, 0,73 and 0.79, respectively; all of which were statistically significant (p<0.001). the correlation coefficient of dts with problem-focused, emotional-focused, less useful and insufficient coping with stress were found to be: 0.213, -0.278, -0.337 and -0.196. in addition, the correlation coefficient of dts with positive emotion, negative emotion and smoking-dependency were 0.543, -0.224 and -0.653 which were also significant(p<0.05). conclusion: the dts is valid and reliable and suitable to use for assessing distress tolerance.
