Final answer:
A characteristic of a person with positive mental well-being is having a positive attitude and optimism, which can lead to better overall health and resilience.
Step-by-step explanation:
A characteristic of a person with positive mental well-being is having a positive attitude and optimism. Research has shown that individuals with positive mental well-being are healthier, better able to cope with stress, and less depressed compared to those with an external locus of control (Benassi, Sweeney, & Durfour, 1988; Lefcourt, 1982; Maltby, Day, & Macaskill, 2007; Whyte, 1977, 1978, 1980).
Further studies have also found that positive psychological well-being is associated with better cardiovascular health (Boehm & Kubzansky, 2012), overall psychosocial processes related to health (Steptoe, O'Donnell, Marmot, & Wardle, 2008), and even the common cold (Cohen et al., 2003).
Additionally, having a positive attitude and optimistic outlook at work can contribute to career success (Craft et al., 2012). Cultivating positive mental well-being can lead to better overall health and resilience.
