In this paper a self-report questionnaire on reading-writing difficulties for adults in Spanish (ATLAS) is presented. Two studies were carried out to determine the validity and reliability of ATLAS. The first study was aimed to select the critical items and to assess their reliability and discriminability. In the second study the assessment reported through the answers to the questionnaire was contrasted with the results of psychometric tests. Results showed that (a) items were suitable descriptors for adult difficulties, (b) there were significant correlations between self-report scores and reading measures, and (c) the items discriminate between good and poor readers. The results of this study demonstrated that ATLAS is a reliable tool to screen adults with reading difficulties. As a further advantage, ATLAS is an easy-to-use and time-saving instrument.
