What is it?
The Social Responsiveness Scale (SRS) is a tool primarily used for quantitative measurement of autism symptoms in the general population, including individuals who do not have a clinical autism diagnosis.It measures the severity of autism spectrum symptoms as they occur in natural social settings [1]. Although it is not a diagnostic tool for autism, it provides a clear picture of functioning in areas that could be impacted in autism.
There is both a child version filled out by caregivers and an adult self-report measure.
Five Subscales
- Social Awareness: Recognition of social cues
- Social Cognition: Interpretation of social cues
- Social Communication: Conveyance of appropriate responses to social cues
- Social Motivation: The extent to which a respondent is generally motivated to engage in social-interpersonal behavior.
- Autistic Mannerisms: Stereotypical behaviors and highly restricted interests characteristic of autism [2].
Scoring and Interpretation
The SRS is a 65-item rating scale, with responses ranging from "not true" to "almost always true." Scores are computed for each subscale as well as a total score that measures severity along the autism spectrum.
- Scores of 76 or higher: severe
- Scores of 60-75: mild-moderate, indicates presence of some autism symptoms
- Scores below 59: considered within typical limits, indicating no significant issues with social responsiveness [2]
History
The SRS was first developed by John N. Constantino and Christian P. Gruber, who published it in 2005. It was designed to be a quantitative measure of autism traits in the general population, including individuals who do not necessarily have an ASD diagnosis [3]. The child version was filled out by caregivers. The SRS for adults was designed to extend the applicability of the SRS to adults, addressing the need for a quantitative measure of autistic traits across the lifespan [3].Psychometrics
The SRS demonstrates good psychometric properties. It has high internal consistency (Cronbach's alpha = .97) and test-retest reliability (Intraclass correlation = .88) [4]. The inter-rater reliability is also good, ranging from .76 to .95 [5].
