This study investigated the validity of the factor structure of the Wi de Range Assessment of Memory and Learning (WRAML) in samples of child ren with attention deficit hyperactivity disorder (ADHD) and reading d isability, as well as a group of controls. An attention/concentration factor emerged for all 3 groups. For the ADHD group it accounted for t he highest proportion of the variance. These results support the valid ity of an attention/concentration factor and call into question the 3 published indexes of the WRAML.
