Background. Self-perceptions of performance of activities of daily living (ADL) and instrumental activities of daily living (IADL) are reduced following stroke. Research investigating contributing factors is lacking. Purpose: We examined the extent to which aphasia status, neurological impairment and poststroke depression, and anxiety contribute to self-perceived ADL/IADL function. Method: Seventy-six community-dwelling individuals at least 6 months poststroke, 44 with and 32 without aphasia, participated in the cross-sectional study. The Stroke Impact Scale (SIS) ADL/IADL domain was the primary outcome measure with aphasia status, residual neurological impairment, depressive symptoms, and anxiety as predictor variables. Findings: Aphasia status, residual neurological impairment, and anxiety were independent predictors of self-perceived ADL/IADL function, together accounting for more than half the variance. Depression was not associated with ADL/IADL. Implications: Clinician awareness of the influence of anxiety on self-perceived ADL/IADL function, particularly for people with aphasia, may lead to future interventions that improve self-perceived ADL/IADL function.

自我感知的 ADL/IADL 功能受残余神经损伤、失语和焦虑的影响。

背景。中风后，对日常生活活动 (ADL) 和工具性日常生活活动 (IADL) 表现的自我认知降低。缺乏调查促成因素的研究。目的：我们检查了失语状态、神经功能障碍和卒中后抑郁以及焦虑对自我感知 ADL/IADL 功能的影响程度。方法：76 名中风后至少 6 个月的社区居民参与了横断面研究，其中 44 名患有失语症，32 名没有失语症。中风影响量表 (SIS) ADL/IADL 域是主要结果测量，其中失语状态、残余神经功能障碍、抑郁症状和焦虑作为预测变量。结果：失语状态、残余神经功能障碍、和焦虑是自我感知 ADL/IADL 功能的独立预测因子，加起来占方差的一半以上。抑郁症与 ADL/IADL 无关。启示：临床医生意识到焦虑对自我感知 ADL/IADL 功能的影响，特别是对于失语症患者，可能会导致未来的干预措施改善自我感知 ADL/IADL 功能。
