Short Description of Instrument
Published in 2005, the BYI-II is used to evaluate children's and adolescent's emotional and social impairment. This is a self-report form that assesses each area over the past two weeks. Inventories may be used individually to isolate specific aspects of a child's mental health.

Time to complete: 5 minutes per inventory (5 inventories of 20 questions each); 30-60 minutes for total instrument
Number of items: 100
Disruptive Behavior
Scoring and Psychometric Properties
Scoring: Uses a 4-point Likert scale from 0 (never) to 3 (always)
Requires a doctorate in psychology, education or a related field with training in the BYI-II.
Psychometric Properties:
Sample for development of norms - 1,278 children and adolescents ages 7-18 from the U.S. Sample was reflective of U.S. population demographics.
Reliability - The authors report internal consistency (alpha) coefficients ranging from 0.86 to 0.96, and test-retest reliability correlation coefficients ranging from 0.74 to 0.93. Another study found alphas of 0.87 to 0.92, and test-retest coefficients that were all greater than 0.70.
Validity - The authors report evidence of good concurrent validity for each of the individual inventories (except the anger inventory) with measures of those constructs (e.g., the depression inventory with the Children's Depression Inventory), and discriminative validity. A further study found that while the BYI could differentiate between clinical and non-clinical samples, it was not able to reliably discriminate between internalizing disorders, with the exception of depression.
  • Brief administration
