sample of population Sex, race/ethnicity, parent education,
geographic region, clinical/special education classification
▫Clinical Norms ADHD norms and LD norms
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
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
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
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
