Test-retest reliability of the short version of the everyday technology use questionnaire (S-ETUQ).

Background: Everyday technologies (ET) such as smart phones, and internet banking are increasingly incorporated into daily activities. Therefore, valid assessments are needed to identify ability in ET use and to design and evaluate interventions.Aims: To evaluate and compare the stability over time (test-retest reliability) of measures generated with the short version of the Everyday Technology Use Questionnaire (S-ETUQ) in older adults with cognitive impairment or mild dementia.Materials and Methods: Data was collected with S-ETUQ at two occasions (m = 20.9 days in between) in a sample of (n = 73) older adults with cognitive impairment of different origin (n = 38) or mild dementia (n = 35). Stability of each participant's S-ETUQ measure was examined using standardised difference z-comparisons. The test-retest reliability coefficient of the S-ETUQ measures was determined by Intraclass Correlation Coefficients. Comparisons were performed using Mann-Whitney u-tests.Results: The S-ETUQ measures were statistically stable between the two occasions. Hence, the group of persons with cognitive impairment demonstrated slightly higher stability and fewer differences compared to the group with mild dementia. The ICCs (0.82-0.90) indicated good to excellent agreement.Conclusions: S- ETUQ can be used with older people with cognitive impairments of varying degree to gather reliable and precise information regarding their use of ET.

Detection of activity limitations in older adults with MCI or Alzheimer's disease through evaluation of perceived difficulty in use of everyday technology: a replication study.

OBJECTIVES AND METHODS: Earlier research indicates that the ability to use everyday technology (ET) may be sensitive to subtle functional change. People with mild cognitive impairment (MCI) have been identified as significantly more disabled in ET use compared to controls, albeit less disabled than people with dementia. The aim of this study was to investigate the replicability of these findings using an improved version of the Everyday Technology Use Questionnaire (ETUQ) to compare perceptions of relevance and difficulty in ET use in participants with MCI or Alzheimer's disease (AD) and controls. Additional aims were to explore the validity of ETUQ, and the relationships between perceived difficulty in ET use and cognitive status, mood state, and involvement in everyday life activities. In total, 118 participants were included, 37 with AD, 37 with MCI, and 44 controls. RESULTS: Analyses confirmed that the rating scale of the ETUQ functioned well. The three groups overlapped but differed significantly in their perceptions of ETs relevance (p < 0.05) as well as of difficulties in ET use (p < 0.001). Moderate correlations were also found between ETUQ measures and cognitive status, mood, and involvement in activities, the strongest being that between ETUQ measures and involvement in activities (r = 0.563). CONCLUSION: Taken together, the findings underscore the plausibility of disability already in people with MCI, as the use of ET strongly correlates to involvement in activities. It is therefore important that professionals who meet older adults with cognitive impairment take this aspect of function into account in assessments and targeted interventions.
