Diagnosis and treatment of breast cancer in women, with an estimated incidence of 182,800 new cases in the United States in 2000, is associated with psychological difficulties and diminished emotional well-being. The role of personal and social resources in maintaining emotional well-being is not adequately understood in women with breast cancer. The purpose of this research was to examine the relationships among the variables of optimism, emotional well-being, perceived social support, problem-focused coping, self-transcendence, and symptom distress. Optimism, or the tendency to believe that one will generally experience positive outcomes, is believed to influence emotional well-being. In addition, social support, problem focused coping and self-transcendence are theorized to positively influence emotional well-being. This research developed and tested theoretical formulations, proposed as mediation models, that explain the affects of perceived social support, problem-focused coping and self-transcendence on the relationship between optimism and emotional well-being. Participants consisted of 93 women, 39 years of age or older, with a first time diagnosis of breast cancer, currently in the third week or more of radiation treatment. Participants were recruited from seven outpatient radiation treatment sites in central New Jersey. They completed six self-report instruments. Correlational and multiple regression analysis revealed that optimism was positively and directly related to emotional well-being, optimism was positively and directly related to self-transcendence, perceived social support was positively and directly related to emotional well-being, and problem-focused coping was positively and directly related to emotional well-being. Self-transcendence was found to mediate the relationship between optimism and emotional well-being. Nurses can intervene to assist women with breast cancer through routine use of screening tools for psychosocial assessment, including level of optimism, thereby facilitating the early detection and intervention for women at high risk for emotional distress. Nursing interventions to intentionally extend and deepen a perception of positive elements in the day may lead to an increase in emotional well-being.
