The BYI is a 100-item self-report measure comprising five self-report inventories that can be used separately or in combination to assess symptoms of depression, anxiety, anger, disruptive behaviour, and self-concept.

The five BYI are:

1) The Beck Depression Inventory for Youth (BDI-Y)
2) The Beck Anxiety Inventory for Youth (BAI-Y)
3) The Beck Anger Inventory for Youth (BANI-Y)
4) The Beck Disruptive Inventory for Youth (BDBI-Y)
5) The Beck Self-Concept Inventory for Youth (BSCI-Y).

Each inventory contains 20 questions about thoughts, feelings and behaviours associated with emotional and social impairment. Children and young people describe how frequently a statement has been true for them over the past two weeks.

Psychometric properties

Property Definition BYI
Reliability The extent to which a measure produces stable and consistent results. The BYI shows good to excellent internal consistency, with (alpha) coefficients ranging from 0.86 to 0.96 (Measure Profile, 2012).
Test-retest reliability Degree to which the same respondents have the same score over a period of time, when the measured trait should not have changed. Test re-test reliability correlation coefficients have been found to range between 0.74 to 0.93 (Measure Profile, 2012).
Concurrent validity Degree to which a new measure and a previously validated measure of the same nature produce similar results. 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) (Measure Profile, 2012).
Discriminant validity Extent to which constructs that theoretically should not be highly related to each other are, in fact, not found to be highly correlated to each other. The BYI demonstrates good discriminant validity, and has been found to reliably discriminate between internalising disorders, with the exception of depression (Measure Profile, 2012).


The BYI is to be completed by children and young people aged 7-18 years old.


The BYI is available in English, Danish, French and Polish.


The BYI is a paper-pencil format so the child/young person can complete this on paper or it can be verbally administered if necessary.


Raw scores

• Add scores from Items 1-20 for the total BSCI-Y score.
• Add scores from Items 21-40 for the total BAI-Y score.
• Add scores from Items 41-60 for the total BDI-Y score.
• Add scores from Items 61-80 for the total BANI-Y score.
• Add scores from Items 81-100 for the total BDBI-Y score.


Raw scores are translated into T-scores assigned by age and gender:

• Females 7-10 years old, 11-14 years old, 15-18 years old
• Males 7-10 years old, 11-14 years old, 15-18 years old.

You can use the tables in Appendix A - Tables for Beck Youth Inventories (p.246) to convert raw scores into T-scores.


T-scores for BYI are as follows:

• 55 or less = average
• 55-59 = mildly elevated
• 60-69 = moderately elevated
• 70+ = extremely elevated
