Abstract

Assessment of the level of satisfaction with completing Instrumental Activities of Daily Living (IADLs) using accessible Information Communication Technology (ICT) or Electronic Assistive Devices (EAD) is critical for enabling high quality of life and community participation for people with disabilities (PWD). Currently there are no reliable and valid outcome measures that have been specifically designed for assessing level of satisfaction with completing IADLs using EAD. In this dissertation study, the Electronic Instrumental activities of daily living Satisfaction Assessment (EISA) self-report outcome measure was developed to fill this void. The EISA research study had the following specific aims: (1) identify common functional tasks that all people use ICT to complete; (2) review the literature to identify any existing outcome measures for EAD; (3) develop and establish content validity at acceptable levels; and (4) establish test-retest reliability and internal consistency at acceptable levels. The EISA research study was sub-divided into 4 studies. Study 1, reviewed the literature, to assess, common functional tasks, that all people, with or without disabilities, use ICT to complete. Study 2, reviewed the literature, to identify any existing outcome measures for EAD. This study had three phases: phase 1 reviewed relevant databases to identify any self-report outcome measures for EAD; phase 2 reviewed the National Institutes of Health (NIH) Patient Reported Outcome (PRO) measures; and phase 3 reviewed the literature to identify any self-report IADL measures. Study 3 involved content validation using expert clinicians and EAD users, as domain experts. Study 4 covered establishment of test-retest reliability and internal consistency at acceptable levels. Using the Scale Content Validity Index (SCVI) Average method, the content validity of the EISA, was SCVI = 0.91. Reliability was assessed by conducting a repeated-measures cohort study (n = 84) using the Qualtrics on-line research platform. Both test-retest reliability (Rs = .81) and internal consistency (Cronbach's alpha = 0.88) of EISA were found to be acceptable. The study results indicate that the EISA-Version 1.0 is a reliable and stable tool for assessing the functional performance of individuals who use or need EAD interventions.
