Stress, Health, and Coping Lecture Notes


Overview of Health Psychology

Health psychology emphasizes the role of psychological factors in illness, prevention, and health maintenance.

Adverse Childhood Experiences (ACEs) and Health

In subsequent sections (slides 45-47), the impact of adverse childhood experiences on health will be elaborated upon.

The Biopsychosocial Model in Health Psychology

Historical Context

  • Health Threats: Earlier health issues were primarily caused by infectious agents, such as:
      - Smallpox
      - Polio
      - Measles
      - Mumps
      - Tuberculosis, which was so widespread it necessitated dedicated hospitals such as Freeport hospital in the early 1900s.

  • Current Context: There has been a notable increase in chronic diseases, including:
      - Heart disease
      - Cancer
    These diseases develop gradually and have become prevalent due to advancements in sanitation and medicine, which have decreased morbidity and mortality from infections.

Impact of COVID-19 on Health

Changes Induced by the Pandemic

  • The COVID-19 pandemic has profoundly transformed health considerations.

  • Challenges:
      - Political decisions often contravened scientific understanding of virus transmission, evident in decisions such as the removal of mask mandates in Ontario.
      - Healthcare workers have faced burnout, leading many to leave the profession.

Obstacles in Containing COVID-19

  • Factors complicating the mitigation of COVID-19 spread:
      - The anti-science movement and conspiracy theories regarding the virus.
      - Some individuals prioritize their desire for normalcy over the health risks posed to the vulnerable population.
      - Reports of COVID-19 patients expressing skepticism toward health measures even in the face of mortality.

Historical Perspectives on Pandemics

The Spanish Flu (1918)

  • First identified in 1918, its origin remains unknown.

  • It is estimated to have infected one-third of the global population, resulting in approximately 50 million deaths.

  • Contributing factors to its rapid spread included:
      - High travel rates during World War I.
      - Crowded military living conditions.

  • Lack of advanced medical care and no available vaccines led to public health measures:
      - Mask mandates
      - Lockdowns

  • Resistance to these health measures mirrored contemporary issues with COVID-19.

  • Survivors reported long-term effects resembling Parkinson’s disease.

Understanding Stress

Determinants of Stress

  • The degree of stress experienced by individuals is influenced by:
      - Coping Ability: Individuals cope differently based on:
        1. Different perceptions of what is significant or serious.
        2. Effective coping mechanisms.

Acute vs. Chronic Stressors

  • Acute Stressors: Temporary stressors such as:
      - Preparing for exams
      - Job interviews

  • Chronic Stressors: Long-term stress with no defined endpoint such as:
      - Living in poverty
      - High-pressure jobs
      - Global pandemics.

Types of Stress

  • Frustration: Occurs when a goal is blocked.

  • Change: The need to adapt to new circumstances.

  • Pressure: Expectations to conform or perform.

  • Conflict: Arises from incompatible motivations.

Exploring Frustration and Aggression

Frustration-Aggression Hypothesis (Dollard)

Suggests that frustration leads to aggressive behavior.

Understanding Pressure

Performance Expectations

  • Expectations can compel individuals to behave in specific ways, fostering a pressure to conform or perform.

Types of Conflicts

  • Approach-Approach Conflict: Choosing between two appealing options.

  • Avoidance-Avoidance Conflict: Choosing between two undesirable options (e.g., staying in an unhappy marriage vs. living in poverty).

  • Approach-Avoidance Conflict: Involves a single goal that has both positive and negative aspects (e.g., buying a house entails both a nice home and a significant financial commitment).

Daily Hassles as Stressors

Examples

  • Everyday irritants such as rude drivers or losing personal items.

  • Perception of stress largely depends on cognitive processes.

Impact of Change on Stress

  • Change can lead to stress, with some individuals more sensitive to change than others.

  • The Social Readjustment Rating Scale quantifies life changes in life-change units, suggesting that higher accumulated stress increases the risk of illness.

  • Even positive changes, like marriage, can be stressful due to necessary adjustments.

Chronic Job Stress

The Context of the Pandemic

Certain professions, especially healthcare, have reported chronic stress exacerbated by conditions related to the pandemic.

Physiological Responses to Stress

Fight, Flight, or Freeze Response

Describe the body's immediate reactions to stressors.

The Tend-and-Befriend Response

  • Females are more inclined to rely on social networks for support when coping with stress compared to males.

Mechanisms of Stress

Pathway 1: Sympathetic Nervous System Effects

  • Activation of the adrenal medulla leads to the release of norepinephrine and epinephrine, resulting in:
      - Increased heart rate
      - Elevated blood pressure
      - Increased respiration
      - Muscle tension
      - Decreased digestive activity.

Pathway 2: Hypothalamic-Pituitary-Adrenal (HPA) Axis

  • The hypothalamus stimulates the pituitary gland to release adrenocorticotropic hormone (ACTH), which in turn prompts the adrenal cortex to secrete cortisol. This hormone raises blood sugar and metabolism.

General Adaptation Syndrome (Hans Selye)

Stages of Reaction to Stress

  1. Alarm Stage: Initial reaction to stress.

  2. Resistance Stage: Body attempts to cope with stress.

  3. Exhaustion Stage: Depletion of resources leads to diminished adaptive capabilities.

Emotional Responses to Stress

  • Increased stress correlates with heightened negative emotions.

  • Moving stressors can lead to improved mood as challenges diminish.

Cognitive Responses to Stress

Appraisal Process (Richard Lazarus)

  1. Primary Appraisal: Assessment of the stressor's significance.

  2. Secondary Appraisal: Evaluation of one's resources to cope with the stressor.

Autonomic Reactivity and Stress

  • Individuals exhibit differences in autonomic nervous system response to stress, displaying either high or low cardiovascular activity.

Explanatory Styles

  • Optimistic Style: Generally positive outlook.

  • Pessimistic Style: Tendency to experience more stress.

Social Support's Role in Stress Management

  • Increased social support is associated with decreased stress.

  • Social networks enhance self-confidence in managing stressors and lessen emotional distress.

  • A reduction in in-person social interactions during the pandemic contributed to heightened stress levels.

Personality Factors and Stress

Explanatory Styles

  • Optimistic Explanatory Style: Positive interpretation of challenges.

  • Pessimistic Explanatory Style: Heightened stress levels.

Outlook Variances

  • Optimistic Brand of Pessimism: Hopeful yet realistic about challenges.

  • Defensive Pessimists: Expect negative outcomes and prepare for the worst to mitigate disappointment.

Personality Types and Stress Response

Stress-Resistant Personality Traits

  • Type Hardy: Embraces challenges, seeks control, and views stressors as growth opportunities.

  • Type A Personality: Characterized by competitiveness, impatience, and high levels of anger—linked to increased stress levels.

  • Type B Personality: More relaxed, experiences lower stress and hostility.

  • Type C Personality: Presents vulnerability to stress, often characterized by positivity while struggling to express negative emotions.

Coping Mechanisms for Stress

Strategies

  1. Cognitive and Behavioral Strategies: To manage stress effectively.

  2. Lashing Out: Can be a maladaptive response.

  3. Self-Defense: Avoidant behaviors to protect from stress.

  4. Self-Indulgence: Use of substances or overeating as coping mechanisms.

Flexible Coping Approaches

  • Coping-flexible individuals adjust their strategies based on situational demands:
      - Problem-Focused Coping: Aims to constructively tackle stressors.
      - Emotion-Focused Coping: Addresses emotional responses to stress.

The Interplay of Behavior, Personality, and Social Support

  • Resilience and personality traits enhance immune function and bolster stress resilience.

  • Social support serves as a buffer against stress's negative health impacts.

The Role of Humor in Coping with Stress

Humor as a Coping Tool

Utilized as a healthy mechanism to alleviate stress.

Interaction of Stress and Health

Psychological and Biological Factors

  • Stress negatively impacts body functions such as:
      - Digestion
      - Growth
      - Tissue repair
      - Immune responses.

  • Studies indicate that around 70-80% of medical consultations stem from stress-related issues.

Stress and Heart Disease

Coronary Heart Disease Statistics

  • Second leading cause of death in Canada, responsible for nearly 50,000 deaths annually (Statistics Canada, 2007).

Personality Factors Linked to Heart Disease

  • Type A Behavior: Closely tied to coronary-prone personalities marked by:
      - High competitiveness
      - Impatience
      - Anger and hostility as the most notable predictor of risk.

  • Type B Behavior: Associated with lower stress levels and reduced risk.

Emotional Impact and Heart Disease

Cardiac Symptoms Association

  • Psychological distress can provoke cardiac symptoms among individuals with stable coronary conditions.

Risk Factors

  • Depressive disorders may elevate coronary heart disease risk, with some research suggesting that depression can double the likelihood of developing CHD.

Stress and the Immune System

Psychoneuroimmunology

  • Explores connections among stress, health, and the immune system, focusing on:
      - Immune System Role: Comprises organs, tissues, and cells that combat bodily invaders (e.g., viruses and bacteria).
      - Lymphocytes: White blood cells essential for battling infections.

Immune Response to Stress

  • Initial exposure to pathogens triggers cytokine release from the innate immune system, contrasting with the acquired immune system's antibody production for long-term protection.

Role of Cortisol in Stress

Chronic Stress Implications

  • Persistently elevated cortisol levels can result in long-term inflammation, increasing the risk of various diseases including heart disease and stroke, while simultaneously suppressing immune function.

Posttraumatic Stress Disorder (PTSD)

Definition and Symptoms

  • PTSD is an anxiety disorder stemming from experiencing or witnessing life-threatening events. Signs include:
      1. Intrusive memories, dreams, or flashbacks.
      2. Avoidance of reminders related to the trauma.
      3. Symptoms of depression, anxiety, guilt, or helplessness.
      4. Sleep disturbances and feelings of detachment.

Common Trauma Triggers

  • Events leading to PTSD may include accidents, serious illnesses, domestic violence, combat exposure, and natural disasters.

Vulnerability Factors for PTSD

  • PTSD can manifest at any age, with childhood experiences heightening the risk of developing PTSD later in life.

  • Lifetime prevalence among Canadians is estimated at 10%, with a higher occurrence in women.

Biological Aspects of PTSD

  • Intense biochemical reactions post-trauma can persist long after physical threats.

  • For example, individuals might experience heightened cortisol and norepinephrine levels following significant stressors.

  • Observations suggest that those experiencing severe stressors may exhibit exaggerated responses from the sympathetic nervous system and potentially a reduced hippocampus region, a crucial part of memory and emotional regulation.

Adverse Childhood Experiences (ACEs) Survey

ACEs Framework

  • The ACEs questionnaire consists of ten questions grouped into:
      1. Personal experiences of abuse and neglect.
      2. Family-related issues such as parental substance abuse or domestic violence.

ACEs Impact

  • Research indicates that higher ACE scores correlate with increased risks for physical and mental disorders in adulthood.

Further Exploration of Childhood Trauma

Utilizing the ACEs Test

  • An online ACEs test is available to assess personal risk.

Factors Influencing Health Outcomes

Key Determinants

  • Biological vulnerabilities

  • Exposure to stressors

  • Lack of protective factors or disruptions therein.

Distinction Between PTSD and Complex PTSD

Complex PTSD Overview

  • Complex PTSD arises from prolonged or repeated trauma, distinguishing from PTSD resulting from a single incident. Examples include:
      - Child abuse
      - Domestic violence
      - First responder experiences
      - Incarceration
      - Combat experiences.

Personality Traits Related to PTSD Resilience

  • Traits associated with lower susceptibility to PTSD include:
      - Optimism
      - Constructive coping mechanisms
      - High resilience levels.

  • A robust social environment can provide essential support in mitigating PTSD symptoms.

Evidence-Based Treatments for PTSD

  • Cognitive processing therapy

  • Prolonged exposure therapy, both of which have supportive efficacy.

Stress as a Beneficial Factor

Inoculation Theory

  • Engaging with small amounts of stress can enhance one’s ability to function under greater pressure.

Eustress

  • Refers to optimal levels of stress that promote health and well-being.

The Intersection of Stress, Anxiety, and Performance

Impact on Academic Performance

  • Many students experience anxiety during tests which can impair their focus, despite adequate preparation.

Dunning-Kruger Effect and Learning

Concept Explanation

  • The experience where studying leads to confusion, referred to as “over-studying.”

  • This phenomenon indicates a growing awareness of gaps in knowledge rather than an actual decline in understanding. The Dunning-Kruger effect illustrates the relationship between confidence and competence.

Anxiety and Academic Test Performance

Factors Influencing Performance

- Acknowledging that students frequently know their material but struggle in test situations due to anxiety.

The Yerkes-Dodson Law on Stress and Performance

Overview of the Law

  • Stress has a performance impact influenced by task complexity:
      - Low stress is ideal for complex tasks.
      - Moderate stress enhances performance on moderately difficult tasks.
      - High stress can maintain focus on easy tasks.

Strategies for Improving Test Performance

Applying the Yerkes-Dodson Law

  • Utilize relaxation techniques to reduce anxiety.

- Enhance mastery of course materials, alleviating complexity when performing tasks.

Improving Classroom Success

To maximize efficacy, regularly practice relaxation techniques and apply effective study methods.
