mild dementia (N1⁄428). Module scores for accuracy and time to complete (sec.) were calculated and summed for overall scores that were compared across groups; overall scores were also correlated with proxy-reported functional status questionnaires. Test-retest reliability was assessed over approximately one month. Participants rated the ecological relevance, face validity and user acceptability of each module. Results: Clinical groups differed in both overall SIMBAC accuracy and time scores (p < 0.0001; p 1⁄4 0.0015, respectively). Accuracy and time scores for the entire sample correlated with proxy-reported instrumental activities of daily living scores (rho1⁄4 0.68, -0.45, respectively; p<0.0001). SIMBAC demonstrated excellent ecological validity, face validity and user acceptability. Test-retest Intraclass correlation coefficients for total accuracy and total time scores were high (0.79 and 0.88, respectively). Conclusions: SIMBAC, a brief, cost-efficient computer simulation of five cognitively demanding everyday activities demonstrated excellent validity, reliability, ecological relevance and user acceptability. SIMBAC can be useful in assessing cognitive functional abilities of older adults with varying degrees of cognitive impairment.
