Chapter 6: Health-Related Behavior and Health Promotion

Health-related behaviors are classified according to health status into well behavior aimed at disease prevention, symptom-based behavior that prompts medical consultation, and sick-role behavior focused on recovery. Prevention efforts operate across three distinct levels: primary prevention works to avoid disease occurrence through measures like immunization and safety practices, secondary prevention detects illness early through screening and diagnostic testing, and tertiary prevention manages advanced disease to minimize complications and restore function. The chapter presents multiple theoretical frameworks that explain health behavior adoption. The Health Belief Model proposes that people weigh perceived threat from illness against the benefits and barriers of taking action. The Theory of Planned Behavior identifies intention as the primary predictor of behavior, shaped by personal attitudes, social norms, and confidence in one's ability to succeed. The Stages of Change Model describes behavior modification as a progression through precontemplation, contemplation, preparation, action, and maintenance phases. Conflict Theory emphasizes how stress influences decision-making quality, particularly during high-pressure situations. Beyond rational models, the chapter addresses non-rational processes affecting health choices, including motivated reasoning where people selectively interpret information to support preferred conclusions, unrealistic optimism bias leading individuals to underestimate personal risk, and false hope syndrome involving repeated unsuccessful change attempts. Learning mechanisms through reinforcement and social modeling also shape health behaviors. The chapter recognizes that health behavior is influenced by developmental stage, gender differences in illness patterns and risk-taking, and socioeconomic disparities that affect access to preventive care and health outcomes. Health promotion strategies include motivational interviewing to resolve ambivalence, message framing that emphasizes either benefits or risks, self-management techniques, relapse prevention, and implementation across diverse settings including schools, workplaces, communities, and digital platforms.
