The Social Aptitudes Scale: an initial validation.

Area of Science:

• Child and Adolescent Psychiatry
• Developmental Psychology
• Clinical Psychology

Background:

• Poor social skills are a hallmark of several child and adolescent psychiatric disorders.
• Deficits in social skills are particularly pronounced in autistic spectrum disorders (ASDs).
• Early identification of ASDs is crucial for timely intervention and support.

Purpose of the Study:

• To validate the Social Aptitudes Scale (SAS) as a brief measure for identifying individuals at risk of ASDs.
• To assess the utility of the SAS in a large, community-based sample of children and adolescents.
• To differentiate the SAS from general psychopathology measures.

Main Methods:

• The Social Aptitudes Scale (SAS) was administered to 7,977 British children and adolescents aged 5-16.
• Parents also completed the Strengths and Difficulties Questionnaire (SDQ).
• Clinical raters assigned psychiatric diagnoses based on multi-informant data.

Main Results:

• The SAS demonstrated strong internal consistency (Cronbach's alpha = 0.88) and loaded onto a single factor.
• SAS scores showed modest correlations with the SDQ, indicating it measures distinct attributes.
• The SAS proved significantly more effective than the SDQ in identifying ASDs.

Conclusions:

• Low scores on the SAS indicate an elevated risk for mental health problems in children and adolescents.
• The SAS is a valuable tool for identifying individuals with a substantially increased risk of autistic spectrum disorders.
• This brief measure can aid in the early screening and diagnosis of ASDs.
