Abstract
IMPORTANCE
Currently, no self-report instruments exist for assessing satisfaction with performing instrumental activities of daily living and occupations for people with disabilities using internet-connected assistive devices like accessible smartphones, tablets, laptops, and apps.
OBJECTIVE
To assess the test-retest reliability and internal consistency of the Electronic Instrumental activities of daily living Satisfaction Assessment (EISA) self-report outcome tool.
DESIGN
Repeated-measures cohort study with a time frame of 7 to 21 days.
SETTING
Multicity online recruitment at assistive technology clinics, nongovernmental organizations, advocacy and peer support groups for people with disabilities, and higher education institutions.
PARTICIPANTS
Eighty-four participants with disabilities, age 18 yr or older, with a mean age of 43.3 yr (range = 19-75 yr), and 57% female.
INTERVENTION
Not applicable.
OUTCOMES AND MEASURES
The a priori study hypotheses were that the EISA test-retest reliability scores would be above the minimum acceptable level (Rs > .80) and that internal consistency would be good (Cronbach's α = .70-.90).
RESULTS
On the basis of the study data, the EISA, Version 1.0, demonstrated good test-retest reliability (Rs = .81) and excellent internal consistency (Cronbach's α = .88).
CONCLUSIONS AND RELEVANCE
The results of the test-retest reliability and internal consistency analyses provide good support for the EISA to be used in clinical settings. What This Article Adds: This article documents the reliability and internal consistency of, to our knowledge, the first-ever self-report instrument for assessing satisfaction with performance of everyday occupations for people with disabilities using internet-connected assistive devices such as smartphones, tablets, laptops, and apps.
