The University of Manchester Longitudinal Study of Cognition (Rabbitt et al. 2004) includes individuals from Greater Manchester and Newcastle-upon-Tyne. We focus on first-test wave data where the sample size was the largest. Manchester participants (n=796) were 41–84 years (mean=64.6±6.2) when assessed on personality, and 41–82 years (mean=62.8±6.1) when measured for depression. Newcastle participants (n=751) were 51–86 years (mean=65.8±6.0) when assessed on personality, and 50–84 years (mean=62.7±6.3) when measured for depression. Women comprised ~71% of the samples.
