Post-Renaissance Period

  • Emergence of understanding biological causes of diseases through contributions from:

    • John Hunter: Surgical techniques.

  • Development of Germ Theory of Disease, establishing microbes as causative agents.

Emergence of Health Psychology

  • 1978: American Psychological Association (APA) established the Division of Health Psychology (Division 38).

  • Four Goals for the New Field of Health Psychology:

    1. To study scientifically the causes or origins of specific diseases (etiology).

    2. To promote health among populations.

    3. To prevent and treat illness effectively.

    4. To promote public health policy and improve health care systems.

Twentieth-Century Trends That Shaped Health Psychology

  • Rise of Lifestyle Disorders: Focus on educating people against behaviors contributing to diseases like cancer, stroke, and heart disease.

  • Rising Health Care Costs: Emphasis on preventive measures to manage health and avoid healthcare costs.

  • Biopsychosocial Approach: Development of a more comprehensive model of health and disease, challenging the traditional biomedical model of health.

Overview

Key Concepts in Health Psychology

  • Relationship between health and psychology.

  • Understanding different aspects of health and illness.

  • Exploration of the Biopsychosocial model as a unifying framework.

The Biopsychosocial Model

Biological Context

  • Genomes and Genomics: The study of genes and their functions in health.

  • Evolutionary Perspective: Examines adaptation mechanisms and reproductive success influencing health.

  • Biology and Behavior Interaction: Highlights the continuous interaction between biological factors and behaviors on health outcomes.

  • Epigenetic Factors: Importance of epigenetics in determining which genes are expressed or silenced based on environmental influences.

  • Life-Course Perspective: Focus on how health and illness vary with age and consider leading causes of death across different age groups.

Psychological Context

  • Health and Illness Subject to Psychological Influences

    • The perception and interpretation of health conditions are influenced by psychological factors.

    • Stressful experiences are appraised based on individual mental frameworks.

  • Appraisal and Interpretation of Stressful Experiences

    • How individuals assess life stressors impacts their overall health.

    • Different coping strategies may be employed based on personal interpretations, leading to varied health outcomes.

  • Attitude and Treatment Effectiveness

    • Psychological attitudes can significantly affect the efficacy of medical treatments.

    • Positive patient attitudes may enhance treatment responses.

  • Psychological Interventions

    • Therapeutic strategies aimed at modifying cognition and behavior to improve health.

    • Can include therapies such as cognitive-behavioral therapy (CBT) or stress management techniques.

Social Context

  • Ways People Think About, Influence, and Relate to One Another and the Environment

    • Social interactions impact an individual's health.

    • Community and environment play critical roles in shaping health outcomes.

  • Birth Cohort

    • Refers to a group of people born in the same period, affecting their shared experiences related to health.

  • Gender Identity

    • Gender influences healthcare access and health outcomes.

    • Differences in health behaviors and risks can be traced back to gender.

  • Racial, Cultural, and Ethnic Identity

    • These identities profoundly impact how individuals experience health and illness.

    • Socio-cultural factors shape perceptions and interactions with health systems.

  • Health Factors

    • Acute Disorders

    • Short-term medical conditions that can affect overall health and require immediate attention.

    • Chronic Illnesses

    • Long-lasting health conditions that require ongoing management and have complex social implications.

  • Sociocultural Perspective

    • Focuses on how social and cultural factors contribute to both health and disease.

  • Culture

    • Defined as enduring behaviors, values, and customs transmitted across generations within a group.

  • Ethnic Group

    • Large groups sharing similar values and experiences due to common characteristics such as race or cultural backgrounds.

  • Socioeconomic Status (SES)

    • A measure encompassing income, education, and occupation, significantly affecting health outcomes.

The Biopsychosocial Model: Social Discrepancies

  • Discrepancies

    • Socioeconomic, religious, and cultural patterns contribute to health variations.

    • Observed differences exist among ethnic and racial groups, as well as geographic regions within the U.S.

    • Notable health disparities exist within certain ethnic groups; for instance, Latinos may show significant differences regarding education, income, health status, and disease risk.

The Biopsychosocial Model: Gender Perspective

  • Gender-Specific Health Problems and Barriers

    • Certain health issues disproportionately affect genders and can hinder healthcare access.

  • Gender Bias in Health Research and Care

    • Underrepresentation of women in medical studies leads to gaps in understanding their unique health needs.

  • Masculinity Norms

    • Cultural norms regarding masculinity can prevent men from seeking necessary healthcare.

  • Different Treatment of Men and Women

    • Variations in healthcare practices and research may create inequalities in treatment outcomes.

Applying the Biopsychosocial Model

  • Emphasis on Mutual Influences

    • The model highlights how biological, psychological, and social contexts are interconnected concerning health.

    • It suggests that an ecological-systems approach is vital in understanding health dynamics, where health systems at any level are influenced by those at other levels.

Example: A Biopsychosocial Model of Alcohol Abuse

  • The alcohol abuse model illustrates how psychological influences, social factors, and biological predispositions interact to impact health.
