It’s particular interest for the incidence and influence factors. Methods: The characteristics and their sleep quality by Pittsburgh Sleep Quality Index (PSQI) were measured, respectively. Single-factor analysis and multiple stepwise liner regression analysis were carried out to explore the independent influence factors of sleep quality in adolescents with MADD. Results: The PSQI scores of MADD adolescents was (10.31±3.92). The following variables influenced the PSQI scores of adolescents with MADD: phase of study, sex, smoking, depressive symptoms, loneliness, emotion regulation strategies as expressive suppression and cognitive reappraisal of MADD adolescents. The model was able to explain 56.5% of variance in sleep quality of adolescents with MADD (F = 2.956, P =0.003, R2 = 0.576, adjusted R2 = 0.565). Conclusion: The sleep quality in adolescents with MADD is important. Psychologists are suggested to pay more attention to their sleep quality, which can aggravate their current emotional problems, leading to more serious psychiatric disorders. Support programme in order to guide adolescents with MADD to adopt more positive emotion regulation strategies and less negative emotion regulation strategies, reduce negative emotions such as depression and loneliness can effectively improve their sleep quality.
