  7. Strengths of the BASC-2 (to name a few) • Not only does the BASC-2 assess for personality/behavioral problems, the test will provide you with some of the clients strengths • Addresses symptoms concurrent with the DSM and IDEA • High internal consistency and test-retest reliability • Available in Spanish

  8. Research behind the BASC-2 • Normative Samples • General Norms: based on a representative sample of population • Sex, race/ethnicity, parent education, geographic region, clinical/special education classification • Clinical Norms • ADHD norms and LD norms

  9. Research behind the BASC-2 • Validity Indexes • F Index: respondent is excessively negative • L-Index: child’s tendency to paint an extremely pretty portrait of themselves • V- Index: Highly implausible statement • Consistency Index: respondent answers differently to questions that should be answered the same* • Response Pattern Index: detects patterns in responses* *software scoring only

  10. Research behind the BASC-2 • Teacher Rating Scale • Internal Consistency: high .80’s to high .90’s • Test-Retest: mid .80’s to low .90’s • Inter-rater Reliability: .53-.65 dependent on age

  11. Research behind the BASC-2 • Parent Rating Scale: • Internal Consistency: mid .80’s to high .90’s • Test-Retest: low .80’s to low .90’s • Inter-rater Reliability: .69-.77 dependent on age

  12. Research behind the BASC-2 • Self Report of Personality • Internal Consistency: mid .80’s to mid .90’s • Test-Retest: high .70’s to low 80’s • This becomes better at the college level
