Sensory and cognitive awareness impairment patterns in children with autism spectrum disorder: a factorial analysis of the underlying constructs
ATEC caregiver ratings cluster into five sensory-cognitive impairment patterns you can screen for when individualizing supports for autistic kids.
01Research in Context
What this study did
Researchers asked 145 Ethiopian caregivers to complete the Autism Treatment Evaluation Checklist (ATEC).
They ran a principal-component analysis on the sensory and cognitive-awareness items.
The goal was to see if distinct impairment patterns show up in everyday ratings.
What they found
Five clear factors emerged from the numbers.
Each factor points to a different mix of sensory and thinking-awareness problems.
You can now screen for these five patterns instead of lumping all issues together.
How this fits with other research
Laugeson et al. (2014) argued autism’s core triad may split into separate cognitive routes. Liyew et al. (2025) now show caregiver data support that split.
Bhaumik et al. (2008) found cognitive traits sit on a continuum. The new five-factor map gives you practical bins along that line.
Vassos et al. (2023) also carved parent data into latent classes, but focused on health and screen time. Using both sets of factors gives a fuller child profile.
Why it matters
Instead of saying “sensory issues,” you can now flag which of the five patterns a child shows. Pick targets that match the pattern and track progress on that factor. This quick ATEC screen costs nothing and travels well across cultures.

03Original abstract
Individuals with autism spectrum disorder (ASD) have a wide range of challenges related to sensory and cognitive awareness. In Ethiopia, the increasing prevalence of ASD underscores the need for a comprehensive understanding of the associated challenges and impairments, an area that has not been studied so far. The objective of this study was to investigate the underlying patterns of sensory and cognitive awareness impairments in children diagnosed with ASD at autism centers in Addis Ababa, Ethiopia. An institution-based cross-sectional study was conducted at the Nehemia Autism Center and the Nia Foundation in Addis Ababa, Ethiopia. The study included children aged 4 to 16 years who had a confirmed diagnosis of ASD. A total of 145 study participants involved in this study. Study subjects were identified in collaboration with staff and caregivers. Caregivers of the study subjects were approached by trained data collectors, and written informed consent was obtained. The sensory/cognitive awareness subscale of the Autism Treatment Evaluation Checklist (ATEC) was administered to caregivers. This questionnaire tool has been validated for the autism population in Ethiopia. A face‒to-face interview was conducted. Data analysis was conducted IBM SPSS Version 22 Statistical Software. Principal component analysis with varimax rotation was employed to examine the patterns of sensory and cognitive awareness impairments. The numbers of principal components and factors to be retained were determined by examining the Eigenvalues and scree plot. Eigenvalues greater than 1 were used. The variable composition of each factor was examined by analyzing the factor loadings in the rotated component matrix. High variable loadings above 0.3 were considered for each factor. This study revealed five patterns of sensory and cognitive awareness impairments in children diagnosed with ASD. Pattern 1, limitation in social engagement and exploration (α = 0.822); Pattern 2 challenges in emotional awareness and cognitive responsiveness (α = 0.743); Pattern 3 challenges in story comprehension and creativity (α = 0.62); Pattern 4 difficulties in social reciprocity and reward (α = 0.34); and Pattern 5 trouble with focus and attention (α = 0.12). All of these patterns accounted for 60% of the total variance. In this study, five patterns of sensory and cognitive awareness impairments were identified. Clinicians and therapists may need to consider these patterns for more personalized and effective support of children with ASD.
