Predictors of self-rated memory ability and memory satisfaction across the life span. Regression models are shown for the three age groups with their explained variance (R²) using the predictors sleep problems (PSQI), anxiety (BAI), and depressiveness (GDS). β represents the predictors’ standardized regression weights, i.e., a change of one standard deviation on the predictor scale results in a change of β points on the MMQ scale. Depressiveness was associated with lower Satisfaction scores in all age groups and lower Ability scores in older adults. Anxiety affected both scales, but only in young and older adults, while sleep problems resulted in lower memory satisfaction in middle-aged adults and self-rated memory ability in young and middle-aged adults
