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.
