Abstract
This study examined the relationship between reading motivation and reading comprehension in a sample of 421 twin pairs (MZ = 168, DZ = 253) recruited from The Western Reserve Reading Project. Reading motivation was assessed using the Motivation for Reading Questionnaire, a specific set of scales based on 11 dimensions of reading motivation. Reading comprehension was assessed using the Peabody Individual Achievement Test – Revised and the Woodcock Reading Mastery Test – Revised comprehension subtests. Latent factors were formed for reading motivation and reading comprehension using data from three annual home visits, beginning when children were
6 years old (M =6.09, SD=.69).
