Clinical Psychology - Health Psychology Overview

HEALTH PSYCHOLOGY

  • Health psychology is a subspecialty of clinical psychology that studies how psychological processes influence health and illness.

  • Emerged due to a shift in prevalent diseases from infectious diseases (like pneumonia) to chronic diseases (such as heart disease and cancer) that have behavioral components.

DEFINITIONS: HEALTH PSYCHOLOGY VS BEHAVIORAL MEDICINE

  • Behavioral Medicine: Focuses on the impact of behavior on wellness, integrating knowledge from social sciences and medicine.

  • Health Psychology: A subdiscipline of behavioral medicine emphasizing the influence of psychological processes on health and illness.

STRESS

  • Defined as the psychological/physiological response to demanding situations.

  • Fight-or-Flight Response: Proposed by Walter Cannon; mobilizes energy reserves for immediate responses to threats, adapting to modern forms such as aggressive driving or substance use.

  • Tend-and-Befriend: A response often seen in women, emphasizing social connections for stress relief.

  • Chronic Stress: Prolonged levels of stress leading to negative health impacts.

    • May stem from a fast-paced lifestyle.

GENERAL ADAPTATION SYNDROME

  • Developed by Hans Selye; describes how repeated exposure to stress can lead to vulnerability and illness as the body fails to adapt.

STRESS AND PHYSICAL ILLNESS

  • Chronic stress can lead to:

    • Increased thyroid hormones, insomnia, weight loss.

    • Depleted endorphins causing bodily pain.

    • Reduced sex hormones leading to amenorrhea or infertility.

    • Digestive shutdown causing nausea or bloating.

    • Excess cholesterol linked to hypertension, stroke, aneurism.

  • Weakened immune response due to:

    • Activation of HPA axis increasing cortisol, which deteriorates T-cells crucial for immunity.

    • Increased likelihood of illnesses, exemplified by higher susceptibility to colds in stressed individuals.

PSYCHONEUROIMMUNOLOGY (PNI)

  • Study of interactions between behavior, the nervous system, and the immune system.

STRESS AND DISEASES

  • Stress doesn’t cause diseases like cancer and AIDS but influences their development. Stress-prone individuals may be more susceptible to certain cancers.

COPING WITH STRESS

  • Coping: Process of managing perceived demands exceeding resources.

  • Influenced by both nature (genetic predispositions) and nurture (perception of stress).

Coping Strategies
  1. Problem-Focused Coping: Taking active steps to reduce stress (e.g., preparing for natural disasters).

  2. Emotion-Focused Coping: Changing emotional response rather than stressor itself (e.g., coping with a family member's injury).

SOCIAL SUPPORT

  • Defined as perceived relationships providing support during crises or sharing good fortune.

  • Important for health, as lack of social support can lead to immune breakdown.

  • Composed of:

    • Social Network: Broad range of contacts.

    • Social Relationships: Meaningful interactions.

    • Social Support: Quality and quantity of assistance.

  • Benefits include viewing stressors in a manageable light and the healthful effects of physical touch (e.g., premature babies thriving with massage).

CLINICAL APPLICATIONS IN HEALTH PSYCHOLOGY

  • Weight Management: ABCDS method (Activity, Behavior, Cognition, Diet, Support).

  • Smoking Cessation: STAR method (Set a date, Tell others, Anticipate challenges, Remove cues).

  • Alcohol Use: Pathological use definitions (e.g., tolerance, withdrawal).

  • Pain Management: Integrating psychological factors into medical treatments; biofeedback encourages body awareness.

  • Medical Regimen Compliance: Assisting clients with adherence to medical advice; common barriers include communication and fear of side effects.

  • Coping with Medical Procedures: Helping clients prepare for and manage the stress of medical interventions.

CULTURAL FACTORS IN HEALTH PSYCHOLOGY

  • Historical disparities in health quality among ethnic groups in the U.S.

  • Cultural differences influence understanding and interpretation of health problems.

  • Sources of perceived illness vary:

    1. The Patient: Biomedical factors.

    2. Nature: Environmental toxins.

    3. Social World: Interpersonal conflicts.

    4. Supernatural World: Beliefs in magic or spirits.
