Using the short mood and feelings questionnaire to detect depression in detained adolescents

The Mood and Feelings Questionnaire (MFQ) is examined for its utility in screening youth in juvenile justice settings for depression. In a cross-sectional study conducted at King County Juvenile Detention Center, a representative sample of 228 detained adolescents complete structured assessments, including the MFQ and the Massachusetts Youth Screening Instrument. Fifty youth also complete the Voice-Diagnostic Interview Schedule for Children. Internal reliability coefficient for the MFQ short form (SMFQ) is alpha =.87. Factor analysis produces a unifactorial scale with item loadings of .43 to. 78. At SMFQ cutoff ! 10, sensitivity and specificity are optimized at 1. 00/0. 79. Prevalence of major depressive disorder is estimated at 32.1% (95% Confidence Interval = 25.3% to 39.2%). The SMFQ shows potential for depression screening of detained adolescents.
