As people with intellectual disabilities (ID) today live integrated in society and use different technological artefacts and services in their everyday life, more in-depth evaluation methods are crucial to detect strengths and limitations of their everyday technology use. The Everyday Technology Use Questionnaire (ETUQ) was originally designed to investigate the extent to which older adults with cognitive limitations can use the everyday technology that is of relevance to them. The purpose of this study was to explore and evaluate evidence of the validity of ETUQ among adult persons with ID.
The original 93-item ETUQ was used to interview 120 adult participants with ID, recruited from a region in northern Sweden. A Rasch model was used to analyse the psychometric properties of the rating scale, scale validity, person response validity and person separation.
The ETUQ rating scale displayed sound psychometric properties when used with this sample. The goodness-of-fit statistics showed that 15 (16%) of the 93 items demonstrated higher values than expected. A step-by-step removal process of items not demonstrating fit to the model resulted in an ETUQ version with 46 items (49%) that met all the criteria for scale validity. Fifteen participants (12%), primarily with mild ID, still demonstrated a higher number of unexpected responses included in ETUQ.
The results of this study indicate that the ETUQ generates a valid measure of perceived difficulty in using everyday technology including adult persons with ID.
随着当今智障人士（ID）融入社会并在日常生活中使用各种技术工具和服务，更深入的评估方法对于发现他们日常技术使用的优势和局限性至关重要。日常技术使用问卷（ETUQ）最初是为了调查认知受限的老年人对与他们相关的日常技术的使用程度。本研究旨在探索和评估 ETUQ 在智障成年人中的有效性证据。
使用原始的 93 项 ETUQ 对 120 名来自瑞典北部地区的成年 ID 患者进行访谈。采用 Rasch 模型分析评分量表、量表有效性、个体反应有效性和个体分离的心理计量特性。
当使用该样本时，ETUQ 评分量表显示出良好的心理计量特性。拟合优度统计显示，93 项中的 15 项（16%）的数值高于预期。逐步删除不符合模型的项目后，ETUQ 版本中有 46 项（49%）符合量表有效性的所有标准。仍有 15 名参与者（12%），主要是轻度 ID，在 ETUQ 中仍表现出更高数量的意外反应。
本研究结果表明，ETUQ 可以有效地衡量智障成年人对日常技术的使用难度。
