Reading Comprehension and Phonics Research: Review of Correlational Analyses with Deaf and Hard-of-Hearing Students

This manuscript reviews 28 studies of reading research on deaf and hard-of-hearing (DHH) students published since 2000 that used correlational analyses. The examination focused on assessment issues affecting measurement and analysis of relationships between early phonological or orthographic skills and reading comprehension. Mixed outcomes complicate efforts to determine evidence-based practices, and to develop an accurate model of reading. Across the 28 studies, DHH participants represented a wide age range with potential floor and ceiling effects that reduce score variability for valid correlations. Many studies assessed readers beyond the optimal ages during which early skills develop and are most useful for reading. Reading skills also were assessed using a diverse array of measures and skill definitions. Particularly for reading comprehension, word-level and text-level abilities appear to be different constructs. Suggestions include more consistent skill definitions and differential timing for early- versus later-developing skill assessments to ensure more robust correlational relationships.
