Systematic Development and Test-Retest Reliability of Electronic Instrumental Activities of Daily Living Satisfaction Assessment (EISA)

The purpose of this proposed study, is the development and validation of EISA, a Self-report outcome measurement tool, for assessing the satisfaction of everyday functional needs, for consumers using Electronic Assistive Devices (EADs) as the primary means to complete Instrumental Activities of Daily Living (IADLs). The EISA outcome measure is proposed to be designed as a questionnaire that can be self or interview-administered to users of EADs. The development of EISA shall be modeled along the lines of development of the self-report outcome measure, Functional Mobility Assessment (FMA) (Kumar et al., 2013). The proposed tool EISA, would serve as a dynamic gage, for assessing perceived user function, related to using EADs for completing IADLs. The instrument is proposed to undergo systematic development in three phases. In phase 1, an initial pool of potential EISA items shall be generated, based on literature review data.

In phase 2, content experts (clinician and EADs user) review panels, shall assess the initial pool of potential EISA items for further content validity. The objective of phase 3, would be a validation of the first iteration of EISA, by establishing reliability for test-retest administration and internal consistency, at acceptable levels, by 25-100 EADs users. Statistical analysis for test-retest reliability and internal consistency estimation shall be carried out in phase 3 of the study, using Statistical Package for the Social Sciences (SPSS) version 24 software.
