Single case experimental design study of Carer facilitated Errorless Learning in a patient with severe memory impairment following TBI.

Objectives:To investigate if errorless learning applied by carer(s) in an everyday setting can reduce the frequency of everyday memory problems following severe traumatic brain injury (TBI). Research design:Multiple baseline single case experimental design. Methods and procedures:A patient with severe memory impairment, six years post TBI was recruited via an outpatient neurorehabilitation clinic. ABA analysis was conducted using daily frequency counts of everyday memory problems as an index of change. Experimental intervention:Errorless learning delivered by the patient’s carer, aimed at reducing the occurrence of identified everyday memory problems. The carer was guided in treatment implementation by an Occupational Therapist. Main outcomes and results:Incidence of frequently occurring memory lapses was significantly reduced (p < 0.001) and this was maintained at 3 months post intervention. Conclusion:This study highlights the potential clinical value of errorless learning with self-generated cues applied by carers within an everyday setting.
