Which one of the following is not a correct explanation regarding health as defined by health psychologists?

Correct option is C

Health psychology primarily focuses on psychological, behavioral, and social factors influencing health, illness, and healthcare. It examines how individuals' thoughts, emotions, and behaviors impact their well-being and the progression of diseases.

Option (1): Health promotion and maintenance of health are fundamental aspects of health psychology, including efforts to encourage healthy behaviors, lifestyle modifications, and awareness programs.
Option (2): Prevention and treatment of illness involve studying how psychological factors contribute to disease onset, progression, and management. This includes stress, coping mechanisms, and psychological interventions.
Option (4): The healthcare system and health policy formulation are relevant to health psychology as they influence accessibility to medical services and how public policies promote community health.

However, Option (3) (Health insurance and good health habits) is incorrect because health psychology does not focus on financial aspects such as health insurance. While good health habits are relevant, linking them directly to insurance is misleading in the context of health psychology, which primarily concerns itself with psychological and behavioral aspects rather than economic factors.
