The research behind Mindmore

Validity

The validity of Mindmore's tests has been evaluated in a study where each test was compared with the corresponding paper-based version. The study was conducted in collaboration with Stockholm University, Karolinska Institutet and the University of La Laguna. 81 healthy individuals aged 24–81 years participated. With an interval of 4 weeks on average between the test sessions and in a balanced order, the participants had to undergo two test sessions, one digital and one paper and pen-based, with the same tests. Correlations, t- and equivalence tests showed acceptable comparability between the formats.

Reliability

In collaboration with the University of Skövde, a study was conducted to evaluate the reliability of the Mindmore tests in retesting. The study included 40 healthy individuals who performed Mindmore's tests on two occasions four weeks apart. Primary results from the study were (1) strong correlation between test times for 10 of 14 tests and (2) median Pearson's r for all tests = 0.62, range [0.34, 0.83]. Further analysis of results is ongoing and the article presenting the study is being prepared.  

Normdata

Mindmore uses a regression-based approach to calculate test norms on an individual basis, through test-specific regression weights for age, education, and gender.

Together with Karolinska Institutet and Stockholm University, Mindmore collected standard data for our test batteries. In a recently published article, a total of 720 healthy adult individuals between the ages of 17-93 performed our screening battery, which consists of 22 subtests across five cognitive domains: attention and pace, memory, linguistic ability, visuospatial and executive function.

Regression-based normative data were established for 42 test measures, where linear, non-linear, interaction effects were examined linked to age, gender and level of education.

The test results were most affected by age and to a lesser extent education level and gender. All but one test showed either a linear or an accelerating age-related deterioration. All but two tests showed a positive effect of training, either linear or decreasing after 12 years of training. Gender affected tests linked to memory and executive function. In three tests, an interaction effect between age and level of education showed an increased advantage of education in older days.

The study establishes normative models for 22 traditional cognitive tests adapted for a digital format. These models enable a more accurate test interpretation, leading to better clinical decisions and better care for patients with cognitive impairment.
