From the male adolescents’ population of Nourabad in academic year of 1398-1399, a total of 331 students were selected via multistage cluster sampling method and were tested using Pittsburgh Sleep Quality Index (Buysse, Reynolds, Monk, Berman & Kupfer, 1989), Ruminative Response Scale (Nolen- Hoeksema & Morrow, 1991) and Five Factor Mindfulness Questionnaire (Baer, Smith, Hopkins, Krietemeyer & Toney, 2006) To analyze the data Pearson correlation and structural equation modeling were conducted. The results showed that direct effect of mindfulness on rumination was significantly negative; direct effect of rumination on sleep quality and the direct effect of mindfulness on sleep quality were significantly positive.
