Stress: Impact on Health and Coping Mechanisms

Hans Selye’s General Adaptation Syndrome (GAS)

Hans Selye studied stress in rats and developed the General Adaptation Syndrome (GAS), a three-part theory of stress:

  • Alarm: A stressor is recognized, triggering a physical reaction.
  • Resistance: The body adapts to the stressor.
  • Exhaustion: Long-term stress depletes the body’s resources.

The Immune System and Stress

The immune system comprises:

  • Lymphocytes (white blood cells)
  • Natural killer cells (NK cells)

Immune function is measured by:

  • Counting white blood cells in a blood sample.
  • Measuring NK cell activity after introducing cancer cells.

Stress significantly impacts health, leading to unhealthy behaviors and increased release of immune-hindering hormones.

Key Studies on Stress and Immunity:

  • Bartrop: Demonstrated decreased immune function in response to grief.
  • Stone: Showed a connection between life events and antibody levels.
  • Visintainer: Found that stress increases the speed of cancer progression.
  • Kiecolt-Glaser: Studied the stress of caring for a loved one.

Personality Factors in Stress

  • Type A Personality: Competitive, achievement-oriented, time-urgent, and prone to anger and hostility.
  • Type B Personality: Low levels of competitiveness, time urgency, and hostility.
  • Phony Type B Personality: Appears as Type B but is internally tense, hostile, and troubled.
  • Type D Personality: Suppresses emotions to gain approval from others.

Environmental Factors in Stress

  • Approach-Approach Conflict: Choosing between two desirable options.
  • Avoidance-Avoidance Conflict: Choosing between two undesirable options.
  • Approach-Avoidance Conflict: A choice with both positive and negative aspects.

Psychoneuroimmunology and Hardiness

Psychoneuroimmunology is a branch of health psychology focusing on mind-body interactions.

Hardiness is the ability to cope with stress. Hardy individuals view stress as:

  • A commitment rather than alienation.
  • Controllable rather than powerless.
  • A challenge rather than a threat.

Control and Stress Studies:

  • Brady: Conducted a study with monkeys and stress (though without random selection).
  • Weiss: Found that lack of control over outcomes increases stress in rats.
  • Langer and Rodin: Studied stress and control in nursing homes.

Social Support and Stress

Social support (involvement with others) is crucial for managing stress:

  • Individuals with non-supportive partners have longer recovery times.
  • Strong social connections correlate with longer lifespans.
  • Kraut: Found a negative correlation between internet connections and real-world social interaction.
  • Liu and Yu: Showed that social support on Facebook is not related to well-being.
  • Kross: Found that Facebook use can decrease happiness.
  • Loneliness is linked to lower heart bypass survival rates and poorer sleep quality.

Coping with Stress

  • Primary Appraisal: Assessing whether a situation is important.
  • Secondary Appraisal: Determining how to address the situation (only reached if the primary appraisal is “yes”).
  • Problem-Focused Coping: Directly addressing the stressor by solving the problem.
  • Emotion-Focused Coping: Managing emotions and calming down.

Coping Techniques:

  • Thought suppression: Ineffective.
  • Meditation: A beneficial strategy.
  • Aerobic exercise: Effective with commitment.
  • Thinking positively and optimistically: Generally beneficial and can be learned.

Additional Concepts

  • Pessimists: View failure as internal, global, and stable; success as external, temporary, and specific.
  • Catharsis: Releasing anger through action or fantasy.
  • Anger Diversion Techniques: Waiting, finding healthy distractions or support, and distancing oneself.
  • Adaptation-Level Phenomenon: Judging experiences relative to past ones.
  • Relative Deprivation: Perceiving oneself as worse off than others.

Psychological Disorders

Psychological disorders involve maladaptive thought and behavior causing significant stress.

Approaches to Understanding Disorders:

  • Biological Approach: Disorders result from physical dysfunction.
  • Psychological Approach: Disorders result from past and present life experiences (psychodynamic, behavioral, cognitive).
  • Sociocultural Approach: Disorders occur within the context of society.

Gender and Disorders:

  • Anxiety and depression are twice as likely in women.
  • Substance abuse is twice as likely in men.
  • Social anxiety is higher in men; women are taught to show emotion.

  • Diathesis-Stress Model: Genetic predisposition increases the likelihood of developing a disorder.
  • Biopsychosocial Model: Environmental factors contribute to the development of disorders.
