This study examines reliability and validity and establish Danish norms for the Danish version of the Beck Youth Inventories (BYI) (Beck, Beck & Jolly, 2001), which consists of five self‐report scales; Self‐Concept (BSCI), Anxiety (BAI), Depression (BDI), Anger (BANI) and Disruptive Behavior (BDBI). A total of 1,116 school children and 128 clinical children, aged 7–14, completed BYI. Internal consistency coefficients were high. Most test‐retest correlations were >0.70. A test‐retest difference was found for BAI. Exploratory and confirmatory factor analysis indicated that the five factor structure of the instrument was justified. The BSCI, BAI and BDI discriminated moderately between the norming sample and the clinical group, and the latter group included more children who exceeded the 90th percentile of the norming sample. Diagnostic groups scored higher on relevant scales than norms. Only BSCI and BDI differentiated between diagnostic groups. The BYI showed acceptable internal consistency and test‐retest stability, except for BAI. The BYI did not adequately differentiate between internalizing disorders.
