A meta-analysis of the relationship between attitudes in reading and achievement in reading was conducted to provide a statistical summary to the observed variability in the magnitude of previously reported effect sizes. A total of 32 studies, with a total sample size of 224,615 were used, and included a total of 118 effect sizes. A multilevel approach was used in meta-analysis to determine if variance in the magnitude of effect sizes could be partitioned to study (level 1) and moderator (level 2) levels by using a mixed model approach. Results from the meta-analysis indicated that the mean strength of the relationship between reading attitudes and achievement is moderate (Z r 5 .32), while stronger for students in elementary school (Z r 5 .44) when compared with middle school students (Z r 5 .24). Findings related to selected moderator variables are discussed, with suggestions for future research.Learning to read is the principal learning activity undertaken by children in their first years of school (Chapman & Tunmer, 1995), and the development of their literacy skills is a fundamental role of schools. Educational and psychological researchers have focused their attention on the cognitive components of reading (i.e. reading comprehension, acquisition of fluency, motor skills of reading, etc.), leaving a gap in the area of measuring student attitudes (Gettys & Fowler, 1996). Attitudes have long been held as an important psychological construct as they play an important role in moderating one's level of motivation and intention to read, as well as mediating the relationship between an individual's beliefs and reading activities. Among classroom teachers, it is widely believed that the students' attitude towards reading significantly impacts students' reading achievement (Russ, 1989). Although research has examined the role of attitudes in predicting reading behaviours, inconsistent replication, poor predictive models and the difficulty of separating attitudes from aspects of motivation and self-beliefs have left many researchers to focus on more reliable predictors of reading behaviours, namely cognitive (e.g. comprehension) and conative (e.g. intentions) components.Recent advances in models of reading attitudes development (Mathewson, 1994;McKenna, 1994) have delineated attitudes as mediators or moderators of achievement, rather than a direct corollary, and as Fazio, Zanna and Cooper (1978) noted, 'The inconsistent relationships obtained between attitude and behavior could be better understood if researchers asked ''under what conditions do what kinds of attitudes held
