“…Previous studies have consistently reported that emotional stability (low levels of neuroticism), extraversion, and conscientiousness are positively related to better physical functioning of older adults (Friedman, Kern, & Reynolds, 2010; Jaconelli, Stephan, Canada, & Chapman, 2013; Magee, Heaven, & Miller, 2013) and conscientious older adults are more likely to better take care of themselves and sustain a healthier lifestyle, which will lead them to age successfully (Martin, 2007). In addition, in both cross-sectional and longitudinal studies, researchers have consistently reported that high levels of neuroticism or negative affectivity (e.g., anxiety, anger, depression, and hostility) have an influence on heart disease, cancer, high blood pressure, and negative health behaviors such as smoking, which can subsequently increase mortality (Aldwin, Spiro, Levenson, & Cupertino, 2001; Scheier & Bridges, 1995; Smith, Glazer, Ruiz, & Gallo, 2004).…”
