Factor analysis of the Autism Spectrum Screening Questionnaire.
The ASSQ gives a three-factor profile that helps you decide whether a kid needs an ASD referral or just social-skills help.
01Research in Context
What this study did
The team ran a factor analysis on the Autism Spectrum Screening Questionnaire. They wanted to see if the 27 items group into clear themes.
They worked with school-age children. Parents and teachers filled out the checklist.
What they found
Three clean factors showed up: social problems, autism-linked behaviors, and cognitive style.
The social factor lines up well with the SDQ peer-problems scale. That lets you compare scores side-by-side.
How this fits with other research
Kahng et al. (1999) built the original ASSQ. Posserud et al. (2008) now map its bones, showing which items hang together.
Kopp et al. (2011) add girl-specific items like "avoids demands" to catch female ASD. The three-factor core stays the same; the REV just widens the net.
Posserud et al. (2009) give a parent-plus-teacher cut-off of 17 for population screening. Use that cut-off with the three-factor profile to decide who needs a deeper look.
Why it matters
You now have a quick way to split ASSQ results into social, autism, and cognitive domains. If social scores are high but the other two are low, rule out simple peer conflict before you flag ASD. Pair the profile with the 17-point cut-off to sharpen referrals and save families weeks of wait time.

03Original abstract
The present study investigated the factor structure of parent and teacher Autism Spectrum Screening Questionnaire (ASSQ) in a population of 7-9 years old children. For validation purposes, factors derived were correlated with results on the Strengths and Difficulties Questionnaire (SDQ). A three-factor solution was identified on both parent and teacher ASSQ. Most of the variance was explained by one factor including measures of social function, validated by a high correlation with the SDQ peer problems scale. The second factor included measures of autism-associated problems. The items allocated to the third factor were more specific for a cognitive style typically found in high-functioning individuals with autism/Asperger syndrome. This factor did not correlate highly with any of the SDQ subscales. The results indicated that the screening efficiency of ASSQ could be increased by closer examination of the individual profile of factor scores.
