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
