This study will enroll 50 patients aged 40-90 years with subjective or objective cognitive complaints who visit the Department of Neurology at Oita University Hospital. Using a prospective, randomized crossover design, each participant will undergo both the paper-and-pencil MoCA-J and MoCA Solo-J, administered approximately 4 weeks apart (+/-7 days). The study will evaluate the agreement between the total scores of the two tests (using CCC, RMSD, etc.), the correlation of domain-specific scores, systematic bias, the effect of the avatar-guided self-administration feature on participant performance, and usability (ease of use, burden, completion rate without assistance, etc.). The overall aim is to establish the clinical validity and utility of MoCA Solo-J as a screening tool for mild cognitive impairment (MCI) in Japan.
Agreement between the total scores of the paper-and-pencil MoCA-J and MoCA Solo-J, assessed by:
Concordance Correlation Coefficient (CCC)
Root Mean Squared Difference (RMSD)
Distribution of the discrepancy score, and the proportion of participants whose scores differ by 1 point or less and 2 points or less
Equivalence criteria: Excellent = CCC 0.90 or higher with 80% or more of participants within +/-2 points; Good = CCC 0.80 or higher with 70% or more; Acceptable = CCC 0.70 or higher with 60% or more.
1. Correlation between the two tests for each cognitive domain score (visuospatial/executive function, attention, language and naming, abstraction, memory, orientation), using Pearson's correlation coefficient
2. Difference in mean domain scores between the two tests (paired t-test)
3. Assessment of systematic bias (Bland-Altman plot, one-sample t-test, linear regression)
4. Test administration time, date/time of administration, and interval between tests
5. Rate of completion without assistance and number of assistance events for MoCA Solo-J
6. Usability assessment via brief questionnaires for both administrators and participants (ease of use, perceived burden, perceived differences between the paper and digital versions, and intended follow-up actions/behavior change after receiving results)
7. Agreement in stratified analyses by background factors (age group, years of education, sex, cognitive function level, and technology familiarity)

Prospective observational study. Each participant undergoes both the paper-and-pencil MoCA-J and MoCA Solo-J, with an interval of 4 weeks (+/-7 days) between the two assessments. To offset learning effects and order effects, the order of the two assessments is determined at random by computer after informed consent is obtained: Arm A (paper MoCA-J first, then MoCA Solo-J) or Arm B (MoCA Solo-J first, then paper MoCA-J). Both assessments are cognitive screening tests used in routine clinical practice, and no medical intervention other than the assessments is allocated. Scoring is performed by a physician or psychologist through the administrator portal using de-identified data.
