and cope ineffectively. Coping consists of deliberate, conscious actions such as problem solving or relaxation. As applied to social support, stress and coping theory suggests that social support promotes adaptive appraisal and coping. Evidence for stress and coping social support theory is found in studies that observe stress buffering effects for perceived social support. One problem with this theory is that, as described previously, stress buffering is not seen for social integration, and that received support is typically not linked to better health outcomes. Relational regulation theory (RRT) is another theory, which is designed to explain main effects (the direct effects hypothesis) between perceived support and mental health. As mentioned previously, perceived support has been found to have both buffering and direct effects on mental health. RRT was proposed in order to explain perceived support's main effects on mental health which cannot be explained by the stress and coping theory. RRT hypothesizes that the link between perceived support and mental health comes from people regulating their emotions through ordinary conversations and shared activities rather than through conversations on how to cope with stress. This regulation is relational in that the support providers, conversation topics and activities that help regulate emotion are primarily a matter of personal taste. This is supported by previous work showing that the largest part of perceived support is relational in nature. Life-span theory is another theory to explain the links of social support and health, which emphasizes the differences between perceived and received support. According to this theory, social support develops throughout the life span, but especially in childhood attachment with parents. Social support develops along with adaptive personality traits such as low hostility, low neuroticism, high optimism, as well as social and coping skills. Together, support and other aspects of personality ("psychological theories") influence health largely by promoting health practices (e.g., exercise and weight management) and by preventing health-related stressors (e.g., job loss, divorce). Evidence for life-span theory includes that a portion of perceived support is trait-like, and that perceived support is linked to adaptive personality characteristics and attachment experiences. Lifespan theories are popular from their origins in Schools of Human Ecology at the universities, aligned with family theories, and researched through federal centers over decades (e.g., University of Kansas, Beach Center for Families; Cornell University, School of Human Ecology). Of the Big Five Personality Traits, agreeableness is associated with people receiving the most social
