This systematic review investigates the links between literacy difficulties, dyslexia and the self-perceptions of children and young people (CYP). It builds on and updates Burden's (2008) review and explores how the additional factors of attributional style and the dyslexia label may contribute to CYP's self-perceptions. Nineteen papers are included and quality assessed. Quantitative papers measured the self-reported self-perceptions of CYP with literacy difficulties and/or dyslexia (LitD/D) and compared these with the CYP without LitD/D. Qualitative papers explored the lived experiences of CYP with LitD/D, including their self-views and how these were affected by receiving a dyslexia diagnosis. Results suggest that CYP with LitD/D may be at greater risk of developing negative self-perceptions of themselves as learners, but not of their overall self-worth. Factors found to be relevant in supporting positive self-perceptions include adaptive attributional styles, good relationships with peers and parents, and positive attitudes towards dyslexia and neurodiversity. In some cases, CYP with LitD/D felt that others perceived them as unintelligent or idle; for these CYP, a diagnosis led to more positive self-perceptions, as it provided an alternative picture of themselves. There is a need for further research to explore the impact of attributional style and the potential for intervention, as well as CYPs' experiences of diagnosis and the associated advantages or disadvantages.
