Errorless learning (EL) procedures have been shown to be effective in teaching new information and new procedures to individuals with severe memory impairment. The published studies have been based on comparatively short-term interventions delivered to individuals with relatively circumscribed impairments. In this single case study, we explore the usefulness of errorless learning procedures used for seven years with an adult with profound and complicated memory and executive function impairments associated with three distinct aetiologies. In primary functional areas targeted by the intervention, outcome was documented by behavioural descriptions and a frequency rating scale. Caregiver burden was documented with qualitative descriptors. A financial cost-benefit analysis is also provided. In the absence of change in underlying neuropsychological impairments, DI's everyday functioning in critical areas improved substantially, with corresponding reduction in supports and improved quality of life. Caregiver burden was reduced to acceptable levels and cost-benefit analysis demonstrates substantial ongoing cost savings.
无错误学习（EL）程序已被证明在向严重记忆障碍的个体教授新信息和新程序方面非常有效。已发表的研究基于相对短期的干预措施，这些干预措施针对的是记忆和执行功能损伤相对有限的个体。在这项单一案例研究中，我们探讨了无错误学习程序在七年时间里对一名成年人的有效性，该成年人存在与三种不同病因相关的严重和复杂的记忆和执行功能损伤。在干预的主要功能领域，通过行为描述和频率评分量表来记录结果。用定性描述符记录照顾者的负担。还提供了财务成本效益分析。在神经心理学损伤没有变化的情况下，DI 在关键领域的日常功能得到了极大改善，支持力度相应减少，生活质量得到提高。照顾者的负担降低到可接受的水平，成本效益分析表明持续节省了大量费用。
