Most activities of daily living (ADLs) require the use of both upper extremities. However, few assessments exist to assess bimanual performance, especially among adults living with cerebral palsy (CP). The aim of this preliminary study is to assess the interrater reliability and convergent validity of the Assisting Hand Assessment (AHA) scoring grid applied to unstandardized ADLs.
For this validation study, nineteen adults living with spastic unilateral CP were videotaped performing seven bimanual ADLs. Three raters assessed the videos independently using the 20-item grid of the AHA. Gwet's AC2 was used to assess interrater reliability. Kendall's Tau-b correlation was used between the observation-based scoring grid and Jebsen-Taylor Hand Function Test (JTHFT) scores to assess convergent validity.
Interrater reliability was good (0.84, SD = 0.02). The correlation with the JTHFT was high (τb = -0.74; < 0.001).
The results show the potential of using an observation-based scoring grid with unstandardized ADLs to assess bimanual performance in adults living with CP, but further research on psychometric properties is needed. This method allows for an assessment that is occupation-oriented, ecological, and meaningful.
日常生活活动（ADLs）大多需要同时使用上肢。然而，评估双手表现的方法很少，特别是在患有脑瘫（CP）的成年人中。本初步研究的目的是评估辅助手评估（AHA）评分表应用于非标准化 ADLs 的评分者间信度和聚合效度。
在这项验证研究中，19 名患有痉挛性单侧 CP 的成年人被拍摄了 7 项双手 ADLs。3 名评分者使用 AHA 的 20 项网格对视频进行独立评估。使用 Gwet 的 AC2 评估评分者间信度。使用 Kendall 的 Tau-b 相关性评估基于观察的评分网格与 Jebsen-Taylor 手功能测试（JTHFT）得分之间的聚合效度。
评分者间信度良好（0.84，SD=0.02）。与 JTHFT 的相关性很高（τb=-0.74；<0.001）。
结果表明，使用基于观察的非标准化 ADLs 评分网格评估 CP 成人的双手表现具有潜力，但需要进一步研究心理测量特性。这种方法允许进行以职业为导向、生态和有意义的评估。
