Objective To develop a Chinese translation of the Mood and Anxiety Symptoms Questionnaire-Short Form (MASQ-SF) and evaluate the reliability and the validity in a sample of Chinese middle school students. Methods The questionnaire was administered to 682 middle school students. Internal consistency, testretest and confirmatory factor analyses were analyzed. Results The internal consistency reliability for the total scale was 0.95, and for the four factors ranged from 0.84 to 0.92 and the one month test-retest reliability coefficient for the total questionnaire was 0.78. The mean inter-item correlation coefficient for the MASQ-SF was 0.24,and the mean inter-item correlation coefficient for the four factors ranged from 0. 20 to 0.51. And the results of confirmatory factor analyses (IFI 0.91, CFI 0.92, TLI 0.91, RMSEA 0.06). The factors loadings ranged from 0. 28 to 0.71. The squared multiple correlations were 0.12 to 0.53. Indicated that the four-factor structure of the MASQ-SF was suitable for the Chinese middle school sample. Conclusion The Chinese version of the MASQ-SF with acceptable psychometric quality,and appropriate for assessing anxiety and depression in Chinese adolescence.
