Background People with aphasia (PWA) frequently experience difficulties in understanding longer written content such as paragraphs or books. Reading strategies are a promising approach to treat text‐level reading comprehension deficits in PWA. Nevertheless, empirical evidence for their efficacy remains rare. Aims The primary objective of this study was to analyse the efficacy of a strategy‐based intervention on text‐level reading comprehension in PWA. Secondary objectives were to compare the effects of two strategy‐based intervention components and to explore potential moderator effects. Methods & Procedures A protocol was published prior to data acquisition. In a repeated measures trial, 26 German participants with chronic, post‐stroke aphasia participated in a waiting period without aphasia treatment (control condition) followed by a strategy‐based intervention called ‘ Strategiebasierte Textverständnis‐Therapie bei Aphasie’ ( StraTexT , 14 face‐to‐face‐sessions, twice per week, 60 min each). Two strategy combinations, Intervention Micro targeting microstructure and Intervention Macro targeting macrostructure, were applied to newspaper and magazine articles. Participants were randomly allocated to two parallel groups that received these strategy combinations in interchanged sequences. Assessments were implemented before and after each period as well as 3 and 6 months after the intervention. The primary outcome measure was text‐level reading comprehension measured with the total score of a German version of the Test de Compréhension de Textes (TCT‐D). Secondary outcome measures addressed the self‐reported perception of reading abilities, reading activities and feelings about reading (German version of the Comprehensive Assessment of Reading in Aphasia CARA reading questionnaire) as well as selected cognitive functions. Outcomes & Results The per‐protocol‐analysis included data from 22 participants. We found significant small improvements up to 6 months post‐intervention compared to pre‐intervention in the TCT‐D Total ( d = 0.35–0.46) as well as medium to large improvements in the CARA questionnaire ( d = 0.68–0.96). Up to 3 months after the intervention, treatment‐induced improvements in the TCT‐D Total were significantly larger than change without treatment during the control condition. There was no evidence of moderator effects. Furthermore, we found improvements in several cognitive functions. Conclusions & Implications Reading strategies can lead to long‐term improvements in text‐level reading comprehension and in self‐reported reading abilities, feelings about reading and reading activities in aphasia. In regular clinical settings, it seems reasonable to implement both Intervention Micro and Intervention Macro. It remains important to investigate participant characteristics that contribute to treatment success. WHAT THIS PAPER ADDS What is already known on the subject Systematic reviews and multiple case studies suggest that reading strategies are a promising approach to treat text‐level reading comprehension in aphasia. The efficacy of reading strategies has been demonstrated for different populations. However, to date no group study has evaluated the efficacy of reading strategies on text‐level reading comprehension in people with aphas
