“ Convergent Validity: The BYI ‐ II manual discusses several validation studies that were conducted. A further study found that while the BYI could differentiate between clinical and non-clinical samples, it was bit able to reliably discriminate between internalizing disorders, with the exception of depression” (Measure Profile, 2012). “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. According to the manual, average standard error of measurement coefficients ranged from 2.12 to 3.37 depending upon scale and age group” (Beck Youth Inventories- For Children and Adolescents 2 nd Edition (BYI-II), 2011). “ Standard Error of Measurement and Confidence Intervals: The manual also discusses the degree to which measurement error contribute to an individual’s observed score. In general, test-retest reliabilities were the same for both males and females. The test-retest reliabilities were calculated, and yielded correlation coefficients in the ranges of.74 to.90 for ages 7-10.84 to.93 for ages 11-14, and.83 to.93 for ages 15-18. “ Test-retest Reliability: A sub-sample (105 individuals) of the general population samples were retested with the BYI-II approximately one week after the first administration. “The BYI-II manual discusses three kinds of reliability that were studied using the general population normative samples: “ Internal Consistency: An analysis of internal consistency yielded a Cronbach’s alpha coefficient that ranged from.86 to.91 for ages 7-10.86 to.92 for ages 11-14, and.91 to.96 for ages 15-18, across all five scales. Another study found alphas of 0.87 to 0.92, and test-retest coefficients that were all greater than 0.70” (Measure Profile, 2012). “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. Population demographics” (Measure Profile, 2012). Psychometric Properties “1,278 children and adolescents ages 7-18 from the U.S. Target Population Children and adolescent ages 7-18. (sub) Scales 5 inventories (depression, anxiety, anger, disruptive behavior, and self-concept) with 20 questions each (Measure Profile, 2012). It is NOT a diagnostic instrument“ (Measure Profile, 2012).ĭescription 100 self-reported or verbally administrated items (Measure Profile, 2012). The individual inventories may also be used in isolation to assess specific aspects of child and youth mental health.
Measurement Characteristics Purpose “This instrument is intended to provide a broad assessment of a child or adolescent’s current mental health. Retrieved from: Evaluation Methodology “This instrument can be used as a measure of self-concept and psychological well-being in children and adolescents, as a measure to identify children and adolescents in need of further intervention or evaluation, and as an assessment of symptom severity” (Measure Profile, 2012).
