WASI-II Wechsler Abbreviated Scale of Intelligence

The WASI-II (Wechsler Abbreviated Scale of Intelligence) is an IQ test for ages 6-90.  It is a shorter and simpler measure based on the more comprehensive Wechsler Intelligence Scale for Children (WISC) and the Wechsler Adult Intelligence Scale (WAIS). 

WASI-II measures cognitive abilities across a range of domains and provides an estimate of a person's general intellectual ability (or Full Scale IQ - FSIQ). It is often used in research studies, and often used to screen for intellectual disability or giftedness, or to assess cognitive abilities in the context of neuropsychological evaluations or clinical diagnoses.

Uses in autistic population
  • Assessment of Cognitive Abilities: believed to help identify cognitive strengths and weaknesses in verbal comprehension and perceptual reasoning, which can be informative for planning educational/ behavioral interventions.
  • Research: frequently used in autism research studies as measure of cognitive ability.
  • Diagnosis: While the WASI-II itself isn't a dx tool for autism, it can be part of a broader diagnostic assessment as it is believed that understanding an individual's cognitive functioning can perhaps provide context for other symptoms or behaviors.

STAT: Screening Tool for Autism in Toddlers and Young Children

The Screening Tool for Autism in Toddlers and Young Children (STAT) is a play-based screening measure designed to identify early signs of autism  in toddlers and young children. It t assesses social communication and play behaviors associated with ASD in children between 24 and 36 months of age.

Limitations
The STAT is a screening tool and not a diagnostic instrument. A comprehensive evaluation by a qualified professional is necessary for a definitive autism diagnosis.

Scoring and Interpretation
The STAT includes a series of play-based activities and social interactions between the child and the examiner. The examiner observes and scores the child's behaviors in different domains, such as joint attention, pretend play, and social responsiveness.

The STAT scoring involves rating specific behaviors observed during the play-based interactions. The scoring criteria may vary depending on the specific version or adaptation of the STAT being used. There are established cutoff scores that help identify children who may be at risk for ASD and require further evaluation by a qualified professional.

History and Revisions:
The STAT was developed by Wendy Stone, Barry L. Prizant, and Samuel P. Openden in 2008.
