There are indications that awareness may have an important impact on functioning and response to rehabilitative interventions in early-stage Alzheimer's disease (AD), yet studies have so far produced few clear findings, and a comprehensive explanatory model is needed together with a reliable assessment method. A theory-driven approach to assessing awareness in early-stage Alzheimer’s disease was used to develop the Memory Awareness Rating Scale (MARS), a measure that addresses key methodological limitations of the assessment methods adopted in existing studies. The MARS was piloted with 12 couples where one partner had a diagnosis of AD. This demonstrated that the MARS has satisfactory psychometric properties, and suggested some refinements to the scale that may improve its usefulness. Results obtained with the MARS allow further consideration of theoretical and methodological issues that arise in attempting to understand and assess awareness. The development of this rigorous method of assessing awareness of memory difficulties in early-stage AD provides a basis for further investigation of the relationship between awareness of memory difficulties and outcome of neuropsychological rehabilitation in early-stage AD
