Clearly, the attitudes, values, expectations, and beliefs that individuals possess about literacy will play a vital role in shaping their engagement with reading, writing, and other language processes. Grounded in Self-Efficacy Theory (Bandura, 1977, 1982; Schunk, 1984), the Reader Self Perception Scale Version 2 predicts that students take four basic factors into account when forming literacy self-perceptions: Progress, Observational Comparisons, Social Feedback, and Physiological States. Student response data (n=3,031 in grades 7-10) provides evidence of construct validity through a principal components analysis of the factor structure. Alpha reliabilities by factor are reported.
