The purpose of the present study was to examine whether individual differences, such as age, education, neuroticism, and conscientiousness, as well as depressive symptoms explain discrepancies between subjective memory and objective memory. A sample of 916 participants of the 2000 Wave Panel 3 from the Long Beach Longitudinal Study was used in this study. A middle adulthood group (40-64 years) and a late adulthood group (65--98 years) were created to explore underlying latent factors within the Geriatric Depression Scale (GDS). Four GDS factors were identified in the late adulthood group while no factor structure was extracted from the middle adulthood group. The validity of the four GDS factors was tested by using confirmatory factor analysis. The four factors were Dysphoria, Vigor/Withdrawal, Cognitive Concerns, and Agitation. A Complex Factor Depression model including the GDS factor structure was created for the late adulthood group. Structural equation modeling (SEM) was used to test the Complex Factor Depression model. The SEM yielded several major findings. Dysphoria negatively predicted objective memory; yet did not predict subjective memory. This suggested that people who score high in Dysphoria might not be able to sense their memory failures even though they obviously showed poor performance in objective memory. Cognitive concerns negatively predicted subjective memory, but did not predict objective memory, suggesting that people with more cognitive concerns could perform in objective memory tests as well as people with less concern in their cognitive decline. Additionally, age, neuroticism, and conscientiousness negatively predicted mnemonic usage, indicating that older people use mnemonics more frequently to offset their memory failure than younger people, and that the more neurotic people are and the more conscientious they are, the more frequently they use mnemonics. Lastly, neuroticism negatively influenced subjective memory, indicating that more neurotic people showed a more negative view of their subjective memory. Conscientiousness positively predicted subjective memory, suggesting that more conscientious people showed a more optimistic view of their subjective memory.
