This study was performed to develop an assessment tool for matching of meal support assistive technology devices (ATDs), and to verify the validity and reliability of this tool. To determine items for the matching assessment tool, a questionnaire survey was conducted among 40 specialists regarding items that they considered the most important for evaluating the matching of ATDs. The following 10 items were extracted: “simplicity of grasp,” “operability of the ATD,” “range of reaching to the mouth and tableware,” “ease of food intake,” “comfort of use,” “appearance: design, form, color, and acceptability of the ATD,” “dimensions: convenience of the deviceʼs size (height, width, length),” “weight: ease in lifting and/or moving the ATD,” “ease in acquiring the ATD,” and “durability, robustness, and sturdiness of the ATD.” The items were divided into the following four categories: operating characteristics, psychological characteristics, device characteristics, and management and maintenance. Each item was evaluated using three ratings (3: matching, 2: possible matching, 1: not matching). As both patient motion and the device itself could potentially affect “simplicity of grasp,” “operability of the ATD,” “range of reaching to the mouth and tableware,” and “ease of food intake,” when level 2 evaluation was applied, this was further evaluated regarding whether improvement was required by the person operating the device or the device itself. A significant positive correlation was observed for “weight” and “comfort of use,” which appeared on both our matching assessment and the QUEST. Therefore, the proposed matching assessment tool had high validity for evaluation. As the level of coincidence for each item on the three-point scale was significantly high according to both test-retest and inter-rater results, this established the reliability of our matching criteria. Using the assessment tool, as the therapist actually observed and evaluated ATD matching during device usage, we believe that it could become a useful method for investigating improvement measures for supporting independence. In future, it will be necessary to also investigate matching criteria for other ATDs. The assessment items of psychological characteristics, device characteristics, and management and maintenance developed in this study would be applicable to other ATDs. However, for operating characteristics, each type of operation must be analyzed and appropriate evaluation items extracted because operation differs depending on the ATD used.
