Overview

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 Degree to which respondents in a similar sample had similar scores. No information at present.
Test-retest reliability The degree to which similar items within a scale correlate with each other. The BYI shows good to excellent internal consistency, with (alpha) coefficients ranging from 0.86 to 0.96 (Measure Profile, 2012).
Concurrent validity Degree to which the same respondents have the same score after period of time when trait shouldn’t have changed Test re-test reliability correlation coefficients have been found to range between 0.74 to 0.93 (Measure Profile, 2012).
Discriminant validity Inverse correlation with opposite concepts The BYI demonstrates good discriminant validity, and has been found to reliably discriminate between internalising disorders, with the exception of depression (Measure Profile, 2012).

 

Populations

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

Translation

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

Administration

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.

Scoring

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.

T-Scores

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.

Interpretation

T-scores for BYI are as follows:

• 55 or less = average
• 55-59 = mildly elevated
