BackgroundHuman health is determined by a number of physical, social and psychological factors, including the often considered health behaviors. They are an indispensable part of the health recovery process and are also the basis of prevention in the development of such disorders as atherosclerosis. Health behaviors are reinforced by an individual’s resources such as posi-tive orientation, which is composed of optimism, high self-esteem and satisfaction with life. The main objective of the study was to determine whether there is a relationship between positive orientation and health behavior, in a group of peo-ple with atherosclerosis.Participants and procedureSixty-one patients, both male and female, in late adulthood were surveyed (M = 69.41, SD = 5.44). A researcher-designed questionnaire, the Health Behavior Inventory (IZZ) and the Positive Orientation Scale (P-Scale) were used in the measure-ment. The study was conducted in accordance with the ethical principles of the 2013 Declaration of Helsinki.ResultsThe results showed that patients with a more positive attitude toward life are more likely to use health-promoting behav-iors.ConclusionsThere is a positive relationship between positive orientation and health behaviors. Positive orientation can be enhanced through appropriate psychoeducation and psychological support to prevent ill health and improve treatment of patients with atherosclerosis.
