Neuropsychological rehabilitation: application of a modified multiple baseline design

The treatment of brain impairment following traumatic injury has proliferated in the past few years. Because many proposed treatment methods have not yet been proven, an important aspect of each treatment attempt is the evaluation of possible gains derived as a result of treatment. A modified multiple baseline design has been suggested as a means of partialing out extraneous influences in the assessment of treatment effects. This paper presents data from the application of a modified multiple baseline design to the treatment of memory and abstraction deficits in a young man who had experienced a closed head injury. Both psychometric-nomothetic and idiographic data are presented and discussed.
