AnnotationDepressive symptoms have been represented in the research and clinical literature in terms of both an episodic phenomenon and as enduring individual differences. Depressive symptoms were investigated longitudinally in a sample of 773 people initially aged 73 (39% women) in the Baltimore Longitudinal Study of Aging who provided biennial Centre for Epidemiological Studies - Depression (CES-D) data on up to to five occasions over an 8-year period. Symptoms increased longitudinally on all subscales, and accounting for a 1-point increase per decade. Trait-like variability accounted for at least two-thirds of the reliable variance. Inter-individual differences were consistent over time, but occasion-specific variability diminished across occasions. (RH).
