Development and content validation of the Electronic Instrumental activities of daily living Satisfaction Assessment (EISA) outcome tool

ABSTRACT

This study describes the development and content validation of the Electronic Instrumental activities of daily living Satisfaction Assessment (EISA), a self-report outcome measure for assessing satisfaction with completing instrumental Activities of Daily Living (IADL) for People With Disabilities (PWD) using internet-Connected Assistive Devices (iCAD). For this study, an iCAD is defined as any information communication technology/electronic device or software that assists with promoting, maintaining, and/or enhancing the ability of a PWD to live independently in society. Phase 1 of development involved generating an initial item pool based on a literature review. Content validity of the EISA was computed in Phase 2 using the Qualtrics on-line research platform. Utilizing the content validity index procedure, EISA demonstrated acceptable content validity: item level (I-CVI of 0.78 or higher) and scale level (S-CVI/Ave of 0.90 or higher). EISA version 1.0 was generated in Phase 3 where it is the first of its kind outcome measure specifically designed for assessing satisfaction with completing IADL for PWD using iCAD.
