Where do autistic teens struggle with reading and writing?
Autistic teenagers read words and answered text questions as well as their peers, but they did worse when reading required switching strategies and when writing stories, and these weaknesses tracked their school grades.

Study at a glance
- Design
- Case-control — Cross-sectional comparison of an autistic group and a typically developing group, with MANCOVAs controlling for IQ, vocabulary and parental education, plus within-group correlations and regressions predicting school grades.
- N
- N=56 · 56 adolescents aged 12-14: 30 autistic without intellectual disability (28 boys) and 26 typically developing (17 boys).
- Population
- Adolescents in the Valencia region of Spain around the transition to secondary school; autistic group had a prior clinical diagnosis confirmed with the ADI-R and SCQ, IQ above 80
- Outcome
- Word reading accuracy and speed, literal and inferential comprehension, a 'mental flexibility' reading-strategy subtest, narrative writing (length, syntactic diversity, coherence), parent-reported grades and transition success

What they did
The researchers tested 56 Spanish adolescents aged 12 to 14, 30 autistic without intellectual disability and 26 typically developing, one-to-one at their schools. They measured reading of a 40-word list, literal and inferential questions about two expository texts, a subtest asking students to adapt and explain their reading strategies, and a story written about a birthday picture that was scored blind for length, variety of complex sentences and coherence. Parents reported recent grades and how well the move to secondary school had gone, and group differences were tested while controlling for IQ, vocabulary and parents' education.
What they found
The groups did not differ in word-reading accuracy, reading speed, or literal and inferential comprehension. The autistic group scored lower on the flexibility-dependent reading subtest, a large effect with partial eta squared of 0.22, and wrote shorter stories with less varied sentence structure that more often left the story's resolution out. Autistic students also had lower grades and a less successful transition by parent report. Within the autistic group, the flexibility reading score alone explained 31% of the variance in language grades and 24% in maths grades.
The limits
What it doesn't show
With 30 autistic participants, almost all boys, and a single cross-sectional snapshot, the study cannot show that reading or writing weaknesses cause lower grades; the grade links are correlations. The comprehension texts were short expository passages with little social content, which the authors suggest may explain why the usual comprehension gap did not appear, so the null result should not be generalised to narrative or social texts. Several tests had only moderate reliability, writing was sampled from one narrative prompt, and grades and transition success came from parents rather than school records. Some F values reported for grades are identical to those reported for writing, so the exact grade statistics in the text should be treated with caution.
Key terms
- Simple View of Reading
- A model in which reading comprehension is the product of word decoding and language (listening) comprehension, so a reader needs both to understand text.
- Decoding
- Turning written letters into the sounds and words they represent, measured here by accuracy and speed on a word list.
- Cognitive flexibility
- The ability to shift attention and switch strategies when task demands change, an executive function often affected in autism.
- Weak central coherence
- A theory that autistic people tend to process local detail at the expense of integrating information into an overall meaning.
- MANCOVA
- A multivariate analysis of covariance that tests group differences on several outcomes at once while statistically adjusting for covariates such as IQ.

Common questions
Does this mean autistic teens have no reading comprehension problems?
No. They matched peers on these particular expository texts after vocabulary was controlled, but they did worse on a task requiring flexible use of reading strategies, and earlier research finds bigger gaps with socially rich texts.
Why control for IQ and vocabulary?
Both strongly predict reading and writing, so adjusting for them helps show that group differences reflect something about autism rather than general ability or word knowledge.
How does the writing result connect to weak central coherence?
Autistic students described settings, characters and conflicts as well as peers but more often failed to give an ending tied to the conflict, which fits a style that handles parts better than the integrated whole.
