Strategy-based reading comprehension therapy during early acquired brain injury rehabilitation: preliminary results
Kerrin Watter, Anna Copley & Emma Finch
Introduction: An evidence-based intervention and service delivery model for early acquired brain injury reading comprehension rehabilitation (involving multiple-strategy, hierarchical reading) was investigated with 3 clients <3 m post onset as part of their brain injury rehabilitation program.
Materials and methods: A multiple-baseline single case experimental design was used for each participant, with data analysed using Tau-U. Assessments of reading comprehension (impairment and activity level) were performed pre/post intervention, and at follow-up (3–6 months post-treatment). Participants’ perceptions of the intervention and service delivery model were captured via semi-structured interviews.
Results: All participants demonstrated improved reading comprehension post-intervention on all formal measures. At follow-up, reading comprehension was grossly maintained by 2 participants. The single case experimental design results (Tau-U) showed moderate-large intervention effect sizes for factual and inferential reading comprehension, two participants had significant (p = 0.01) changes. Participants reported overall positive experiences with the intervention.
Conclusion: The intervention and service delivery model were successfully implemented in clinical practice, and preliminary results show the intervention has clinical promise with an early acquired brain injury population.
