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). |
Suitability
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
• 60-69 = moderately elevated
• 70+ = extremely elevated
