Dyslexic subtypes and severity levels: are there gender differences?
The prevalence of dyslexia among 100 children participating in a longitudinal study was examined. At age 10 years, The Dyslexia Screener (TDS) test, a direct assessment of coding skills used in reading and spelling, was administered. The incidence of suspected dyslexia of borderline or worse severity among boys and girls was not significantly different, nor did males and females differ significantly in terms of TDS-suspected dyslexic types of severity levels. Results challenge the widely held belief of an increased incidence  of reading disability among males and, in conjunction with findings from other recent studies, underscore the need for establishing objective and reliable screening procedures in addition to teacher referral in identifying children in need of special services. Possible factors mediating previous estimates of incidence and the implications of these findings are discussed.
