The moderation effect of education in the relation between cognitive performance and everyday functioning was not evident in . In the regression model, the total variance explained was .50 and .60, which makes the inclusion of 7 predictors in samples of 92 participants sufficient for a good prediction level (Knofczynski & Mundfrom, 2017). Among the cognitive measures, only VF and TMT-B predicted independently Greek EPT-G scores in the seniors’ final model. Age and education however were statistically significant predictors of both and OTDL-G.
