To investigate and describe getting lost behaviour and wayfinding strategies among acquired brain injury (ABI) survivors and matched controls.
Matched control group comparison design.
This study compared wayfinding performance of 18 adults with acquired brain injury to controls matched for gender, age and education. Participants followed written directions along an eight-step route in an unfamiliar neighbourhood, with three intentionally challenging choice-points. They used a cellular phone to request assistance if they became lost. Dependent measures included accuracy, directness and wayfinding strategy. Statistical and qualitative analyses explored group themes and differences.
Participants with ABI demonstrated significantly greater on-route wayfinding errors and hesitancy than matched controls. The ABI group requested assistance over the cell phone more frequently than controls and required more attempts at re-orientation with concrete, salient directions in order to re-orient in the field. Participants in the control group anticipated errors with greater frequency than those with ABI.
ABI survivors demonstrated greater challenges with wayfinding than matched controls. Re-orientation required concrete, explicit redirection with reference to salient landmarks. Implications for clinical practice and assistive technology are discussed.
调查并描述获得性脑损伤（ABI）幸存者及匹配对照组中的迷路行为和寻路策略。
匹配对照组比较设计。
本研究将18名获得性脑损伤的成年人的寻路表现与在性别、年龄和教育程度上相匹配的对照组进行比较。参与者沿着一条在不熟悉街区中的八步路线遵循书面指示，其中有三个故意设置的具有挑战性的选择点。如果他们迷路了，就使用手机请求帮助。相关测量指标包括准确性、直接性和寻路策略。统计分析和定性分析探究了组间主题和差异。
与匹配的对照组相比，ABI参与者在途中的寻路错误和犹豫表现得更为明显。ABI组比对照组更频繁地通过手机请求帮助，并且需要更多次尝试通过具体、显著的方向来重新定向以便在实地重新找到方向。对照组的参与者比ABI参与者更频繁地预见到错误。
与匹配的对照组相比，ABI幸存者在寻路方面表现出更大的挑战。重新定向需要参照显著地标进行具体、明确的重新引导。文中讨论了对临床实践和辅助技术的启示。
