This paper examines the sensitivity to change over time of the Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ-40). Individuals' health status change was assessed by means of the Rasch-based Reliable Change Index (RCI) for ALSAQ-40 questionnaires completed on two occasions, three months apart. In addition, at follow-up respondents indicated how much change they had experienced since baseline via dimension-specific self reported transition questions. 764 individuals returned questionnaires at baseline and follow-up. For all dimensions, of respondents defined by the RCI as worse, a majority rated themselves as worse. However, on two dimensions over 60% of the respondents who rated themselves as being worse were defined as unchanged by the RCI. As with effect size smaller RCI cut-off points might be needed for subjects with ALS. This study confirms that the ALSAQ-40 is a valid and responsive disease specific health related quality of life instrument for use in studies of patients with ALS or other motor neuron diseases.
