In 2002, Lefly and Pennington published the Adult Reading History Questionnaire (ARHQ), a self-report tool that asks adults about childhood and current reading habits. Research on dyslexia consistently links core deficits to phonological processing (mapping sounds to letters) and reading fluency (accurate, automatic word recognition). The International Dyslexia Association defines dyslexia as a specific learning disability characterized by difficulties with accurate or fluent word recognition and by poor spelling and decoding abilities.

The Quiz Hub built this dyslexia test as an abbreviated, plain-language screener inspired by those research themes. It uses 24 original items and three result bands rather than a full clinical battery. That trade-off favors readability for casual users while naming the Lefly and Pennington (2002) source and IDA definition honestly. NIH notes that dyslexia affects reading and related language-based processing skills and that structured evaluation by a qualified professional is the appropriate path when symptoms affect daily life.

The Quiz Hub testWhat it adds
ADHD testInattention and hyperactivity symptom frequency, not reading accuracy or phonology
Autism testSocial communication and sensory patterns, not literacy-specific screening
Mental health testGeneral mood, anxiety, sleep, and functioning, not reading domains
This dyslexia testFour reading and processing domain scores with core screening flag

Sample item: rating Often on mixing up letters that look alike raises your reading accuracy score. Rating Very often on needing to reread sentences raises fluency. Vision problems, ADHD, and reading in a second language can mimic dyslexia symptoms, so clinicians rule out other causes during evaluation.
