1. The Validity and Reliability of Apps in Adult Rehabilitation
Daniel M. Fichter, OTS and Dr. Rochelle Mendonca PhD, OTR/L
Introduction
There is a national push for the use of evidence-based practice
to quantify occupational therapy evaluation and intervention
processes. 7, 1
The use of technology is increasingly present in occupational
therapy rehabilitation settings, but with limited research on efficacy
for specific populations. 3
Thousands of apps exist that can potentially be utilized in
occupational therapy rehabilitation facilities. Virtual tools allow for
increased repetition, standardization, control and environmental
simulation. 7, 5, 2, 6
Studies report that there is a need for widespread evaluation and
intervention tools for cognitive skills such as neglect, executive
functioning and memory. 2. 1, 6, 8, 4
Methods
Research studies on the use of apps in rehabilitation settings were
gathered and analyzed using levels of evidence and statistical
reports to determine the clinical uses of apps and their validity and
reliability. All search terms were recorded by the researcher and
documented to reveal effectiveness. See the handout for a list of
search terms.
The articles chosen for this analysis mainly concern cognitive
performance skills within functional performance.
Results
Discussion
Research providing psychometric data on the use of apps in adult
rehabilitation is lacking in a time when it is necessary to utilize
evidence-based practice. Only two research articles studying the use
of apps were identified, one of which was created and tested by
researchers with good to moderate test-retest reliability (ICC=0.712)
and mixed convergent validity with the Life Satisfaction Index K
(r=-0.045 - 0.297) 7, 3. When a clinician chooses an existing app, he
or she must account for the lack of supporting psychometric data.
Many of the analysed tools run on other hand-held or virtual reality
platforms. Evidence on the use of virtual reality and reminder
systems on phones is more abundant and can be considered as a
model for practitioners using apps. Many of the virtual tools are
concerned with cognitive functioning and 8/9 present with detailed
descriptive sample data 1,2,3,4,5,6,7,8. Virtual assessments, including apps,
can be inherently higher in reliability and validity due to their abilities
to be systematically repeated and representative of more natural
environments than paper and pencil versions.
Conclusions
Research shows that the use of virtual assessment and intervention
tools can be perceieved as effective due to increased collaboration,
motivation, control, ecological validity and personalization 1,2,3,4,5,6,7,8.
Apps have inherent features that promote reliability and validity
Further research is necessary to progress the use of apps into an
evidence-based model.
Research on the psychometric properties of apps needs to begin
with the creation of assessment criteria, or an assessment tool to
rate their function with specific populations, settings and skill deficits.
Clinicians should be vigilant while using apps in rehabilitation
settings and, with strong clinical reasoning, utlize existing
population-specific research on virtual reality and hand-held systems
to generalize treatment outcomes to the use of apps.
Abstract
Research on the use of apps (iPad, iPod, iPhone) and virtual
systems was analyzed for their validity and reliability data to
provide further information on the evidence supporting their use in
outcome-based practice. The researcher searched multiple
scholarly databases and found that there is a lack of clinically valid
evidence pertaining to the use of apps in adult rehabilitation
settings. This analysis seeks to answer, “Is there reliable and valid
evidence to support the use of apps for occupational therapy
evaluation and intervention with adults in rehabilitation facilities?”

Table: Two out of the nine virtual systems reported run on platforms that support apps. Two virtual tools report reliability and validity data, while four
report validity data only. Three virtual tools are reported with no psychometric data. All reported tools have detailed descriptions of participants.
