Parent form for children and adolescents aged 4-17 and a youth form for adolescents aged 12-17.
Primary: General mental health assessment Secondary: Other
Generalized anxiety, separation anxiety, major depressive and social phobia disorder symptoms, attention deficit hyperactivity, oppositional defiant and conduct disorders.
The measure was designed as a brief, easy to administer, self-completed symptom checklist of child and adolescent psychiatric disorders that are aligned with disorders in theDSM-5 that produces scores that are valid and reliable for both dimensional and categorical use.
The measure is designed for epidemiological studies in the general population and screening in clinical studies based on dimensional and categorical use.
Children and adolescents ages 4-17 (parent version) and adolescents ages 12-17 (youth version).
English, Canadian French is being piloted.
Additional information to inform measure use
All items and scales met the psychometric requirements of validity and reliability. Though there was mixed evidence of the reliability and validity of the conduct disorder scale, the authors recommend retaining the scale to represent behaviors that are rare and concerning and to interpret youth-reported conduct disorder with caution.
Three-point Likert scale from 0 (never or not true) to 2 (often or very true).
7-10 minutes.
None.
No training is required to administer the OCHS-EBS scales.
The OCHS-EBS can be scored as a total score, internalizing score, externalizing score and individual disorder scores. To calculate the total score, all 52 items are summed together. To calculate the scale scores for internalizing disorders, externalizing disorders and individual disorders, the items that make up the groupings can be summed together. A scoring tool is available that produces population normed scores based on children and youth in the Ontario general population. Please contactduncanlj@mcmaster.cato access the scoring tool.
The norms, reliability and validity statistics included in each measure profile are those reported by the author(s) of the measure. It is important to note that altering, adding or removing questions from a measure voids these reported statistics, possibly making the revised tool unreliable and invalid.
Population norms based on child/youth age group and child/youth gender come from the 2014 Ontario Child Health Study of 10,802 children and youth, a representative sample of Ontario children and youth.
When useddimensionally, the authors reported internal reliability with Cronbach’s αall over 0.7 with the exception of youth-assessed conduct disorder and caregiver-assessed conduct disorder for ages 4-11. The authors reported internal coefficient alphas of 0.62-0.87 for the parent/caregiver report (ages 4-11), 0.8-0.87 for the parent/caregiver report (ages 12-17) and 0.66-0.86 for the youth report (ages 12-17).
The OCHS-EBS demonstrated test-retest reliability with Pearson’s r all over 0.7 with the exception of youth-assessed separation anxiety disorder. The authors reported test-retest Pearson’s r of 0.7-0.78 for the parent/caregiver report (ages 4-11), 0.7-0.87 for the parent/caregiver report (ages 12-17) and 0.66-0.86 for the youth report (ages 12-17).
When used categorically, the authors reported there was no significant differences in test-retest reliability estimates between the OCHS-EBS and a structured standardized diagnostic interview, the MINI-KID-P.
When used dimensionally, the authors reported evidence of content validity, internal convergent and discriminant validity (with the exception of youth-assessed conduct disorder scale). The authors noted that there were a few internal discriminant validity test failures that reflect the overlap of characteristics among the disorders. In addition, the authors reported evidence of external convergent and discriminant validity with scales of the independent MINI-KID disorder assessments in 81/84 comparisons of individual disorders. Exceptions occurred between disorders that had similar characteristics.
When used categorically, the authors reported evidence that the OCHS-EBS had similar levels of validity as a structured standardized diagnostic interview.
