User experience with two computerized cognitive intervention programs for people with mild cognitive impairment.

Area of Science:

• Gerontology
• Cognitive Science
• Human-Computer Interaction

Background:

• Computerized cognitive training (CCT) shows efficacy for individuals with mild cognitive impairment (MCI).
• User-friendliness and ease of use are critical for CCT adoption in the MCI population.
• A growing number of individuals are diagnosed with MCI, necessitating accessible non-pharmacological interventions.

Purpose of the Study:

• To evaluate the user experience of two distinct CCT programs designed for individuals with MCI.
• To compare user satisfaction between an individualized CCT (iCCT) and a basic CCT (bCCT).
• To explore correlations between training intensity, user satisfaction, and demographic factors (age, gender).

Main Methods:

• Secondary data analysis from the BrainFit-Nutrition randomized controlled study (N=270).
• User experience evaluated using the User Experience Questionnaire (UEQ) in 217 participants (n_UX-iCCT=109; n_UX-bCCT=108).
• Analysis included benchmark comparisons, inter-program differences, correlation analysis, and demographic variations.

Main Results:

• Both CCT programs achieved above-average benchmark scores across most UEQ scales.
• No significant differences in user satisfaction were found between iCCT and bCCT, except for higher 'Perspicuity' in bCCT.
• Training intensity positively correlated with 'Attractiveness' and hedonic quality (Stimulation, Novelty) for both programs.

Conclusions:

• Both iCCT and bCCT are user-friendly interventions for individuals aged 60+ with MCI.
• Increased usage frequency correlated with higher satisfaction regarding the hedonic quality of the CCT programs.
• These findings support the development and implementation of accessible, non-pharmacological interventions for the growing MCI population.
