| Summary: | The aim of this investigation was to determine how cognitive performance was associated with positive and negative affect and life satisfaction over time. This study involved a secondary longitudinal analysis of cross-section data collected at Phase I (1988–1992) and during an 18-month longitudinal followup at Phase II (1992–1998) of the Georgia Centenarian Study. Participants included 𝑁=137 centenarians at Time 1 and 𝑁=68 survivors at Time 2. Significant stability in cognitive impairment existed at Time 1 and Time 2 for positive (𝛽=.55,𝑃<.01) and negative affect (𝛽=.54,𝑃<.01) models. Negative affect at Time 1 was associated with lower life satisfaction at Time 1 (𝛽=−.42,𝑃<.01
). In addition, cognitive impairment at Time 2 was associated with decreased positive emotionality at Time 2 (𝛽=−.39, 𝑃>.01). Furthermore, greater positive affect at Time 2 was associated with greater satisfaction with life at Time 2 (𝛽=.35,𝑃<.01). It appears that positive emotionality contemporaneously influences the association between cognitive impairment and life satisfaction among centenarians. Implications relative to improving life satisfaction among centenarians are discussed. |
