The Autism Spectrum Rating Scales™ (ASRS) is a multi–informant measure designed to identify symptoms, behaviors, and associated features of Autism Spectrum Disorder (ASD) in children and adolescents aged 2 to 18.
From renowned authors Sam Goldstein, Ph.D., and Jack A. Naglieri, Ph.D., the ASRS is a norm–referenced assessment based on a nationally representative sample designed to identify symptoms, behaviors, and associated features of Autism Spectrum Disorder.
The ASRS serves as a scientifically validated tool, aiding psychologists, school psychologists,
clinical social workers, physicians, counselors, psychiatric professionals, and pediatric/psychiatric nurses in accurately assessing and diagnosing ASD. The ASRS assists in helping to develop effective intervention and treatment strategies and monitoring the response to intervention and treatment effectiveness.
Key Features:
- First nationally standardized, norm–referenced ASD Rating Scale
- Easy administration, scoring, and results interpretation
- Excellent reliability and validity
- Short version can be used for screening or treatment monitoring
- Spanish version available
- Items assess DSM–5 symptom criteria for ASD – DSM–IV–TR scoring still available for online options
- Option to score children with no or limited verbal abilities
- Interpretive, Comparative, and Progress Monitoring reports are available
Reports
Progress Reports compare the results of two to four administrations for the same individual to measure changes over time. These reports are ideal to use when monitoring treatment and intervention effectiveness.
Comparative Reports combine the results of different raters to provide an overview of an individual’s scores from a multi–rater perspective. This highlights potentially important inter–rater differences in scores.
Interpretive Reports provide detailed information about scores from a single administration, presented both numerically and graphically. An individual’s scores are compared to those in the normative sample and elevations at the scale and subscale level are indicated.
Reliability
The ASRS was found to demonstrate high levels of internal consistency (alpha ranging from .74 to .97). Test–retest reliability scores were computed for the ASRS scores over a 2– to 4–week interval. Overall, the test–retest values indicate excellent test–retest reliability (ranging from .72
to .93).
Validity
A series of discriminant function analyses were conducted in order to determine the ability of the scores to predict group membership in the Autism Spectrum Disorder or General Population groups. On average, the scales were able to very accurately predict group membership, with a mean overall correct classification rate of 92%.
Normative Data
The ASRS was standardized on 2,560 non–clinical cases from across the United States. The standardization included 640 cases for the ASRS
(2 to 5 Years) with 320 parent and 320 teacher forms and 1,920 cases for the ASRS (6 to 18 Years) with 960 parent and 960 teacher forms. Over 1,200 clinical cases were also collected. The disorders in the clinical sample include:
- Autism Spectrum Disorder (Autism, Asperger’s, Pervasive Developmental Disorder – Not Otherwise Specified)
- Attention–Deficit/Hyperactivity Disorder
- Mood and Anxiety Disorders
- Disruptive Behavior Disorders
- And many more
