20.1 Health, Stress & Coping
Key Takeaways
- The PA-CAT Bulletin of Information, rev. 20240815 allocates approximately 9% of the exam (22 scored items) to Behavioral Sciences, with health/stress/coping a recurring content group within Table 10.
- Selye's General Adaptation Syndrome (GAS) proceeds through alarm, resistance, and exhaustion stages driven by the HPA axis and sympathetic-adrenal-medullary (SAM) response.
- Lazarus cognitive appraisal theory splits stress into primary appraisal (is this a threat?) and secondary appraisal (can I cope?), making appraisal—not the stimulus alone—the determinant of stress.
- Problem-focused coping targets the stressor itself; emotion-focused coping regulates the emotional response. Chronic reliance on avoidant coping predicts poorer health outcomes.
- Psychoneuroimmunology links chronic stress to suppressed cellular immunity, elevated cortisol, and slower wound healing; behavioral risk factors (smoking, sedentary lifestyle, poor diet) are major modifiers of disease risk.
Health, Stress & Coping on the PA-CAT
Quick Answer: The PA-CAT Bulletin of Information, rev. 20240815 assigns Behavioral Sciences about 9% of the exam (≈22 scored items) distributed across stress, research methods, sociocultural identity, and disorders. Within that block, health, stress, and coping questions test the physiological stress response (Selye GAS, HPA axis), cognitive appraisal (Lazarus), coping strategies, health psychology, and psychoneuroimmunology.
What Is Stress?
Stress is the body's nonspecific response to any demand placed on it. Hans Selye distinguished eustress (positive, motivating stress) from distress (harmful, overwhelming stress). A stressor is the internal or external trigger—ranging from physical injury to psychosocial events like exams, loss, or caregiving.
Selye's General Adaptation Syndrome (GAS)
Selye's General Adaptation Syndrome (GAS) is a three-stage physiological response to prolonged stress:
| Stage | Physiological Events | Clinical Correlate |
|---|---|---|
| Alarm | SAM activation: catecholamine release, sympathetic arousal, "fight or flight" | Initial shock; acute threat response |
| Resistance | HPA axis: cortisol sustained, parasympathetic partially returns, adaptation | Coping; resources mobilized |
| Exhaustion | Depleted resources, immunosuppression, tissue damage | Burnout, illness, cardiovascular risk |
The hypothalamic-pituitary-adrenal (HPA) axis drives the resistance/exhaustion phases: the hypothalamus releases corticotropin-releasing hormone (CRH), the anterior pituitary releases adrenocorticotropic hormone (ACTH), and the adrenal cortex releases cortisol. The sympathetic-adrenal-medullary (SAM) pathway mediates the immediate alarm response via epinephrine and norepinephrine.
Cognitive Appraisal — Lazarus
Richard Lazarus argued stress depends on appraisal, not the stimulus alone:
- Primary appraisal — "Is this event a threat, harm, or challenge to my well-being?"
- Secondary appraisal — "Do I have the resources to cope?"
- Reappraisal — ongoing reassessment as the situation unfolds.
A PA-CAT item may describe a student facing an exam: whether they experience distress depends on whether they appraise it as a threat (high stakes, low control) versus a challenge (manageable, preparable).
Coping Strategies
Coping is the cognitive and behavioral effort to manage demands appraised as exceeding resources.
| Coping Style | Target | Example | Outcome Pattern |
|---|---|---|---|
| Problem-focused | The stressor | Making a study schedule, seeking tutoring | Adaptive when control is possible |
| Emotion-focused | The emotional response | Exercise, journaling, reappraisal | Adaptive when control is low |
| Avoidant | Distancing from stressor | Denial, substance use, distraction | Generally maladaptive long-term |
Lazarus and Folkman's Ways of Coping Checklist operationalized these categories. Chronic avoidant coping (denial, behavioral disengagement) predicts poorer medical and psychological outcomes.
Health Psychology & Psychoneuroimmunology
Health psychology examines how psychological, behavioral, and cultural factors contribute to physical health and illness. Psychoneuroimmunology (PNI) studies the interaction among psychological processes, the nervous system, and the immune system. Chronic stress suppresses cellular immunity (reduced natural killer cell activity), slows wound healing, and reactivates latent viruses through sustained cortisol elevation.
Behavioral risk factors—tobacco use, sedentary lifestyle, poor diet, excessive alcohol—account for a large share of preventable morbidity and are high-yield PA-CAT targets because they connect behavioral science to clinical prevention.
The Biopsychosocial Model in Stress
Engel's biopsychosocial model frames disease as the product of biological (genetics, pathogens), psychological (appraisal, coping), and social (support, socioeconomic status) factors. This model underlies the PA-CAT's emphasis on integrated patient care and is reinforced throughout the PA-CAT Bulletin of Information, rev. 20240815 behavioral competencies.
Worked Example — Appraising a Cardiac Patient
A 58-year-old man awaiting coronary bypass reports insomnia, irritability, and a racing heart. Primary appraisal frames the pending surgery as a threat (potential harm), activating the sympathetic-adrenal-medullary axis. Secondary appraisal evaluates coping resources: he perceives low control and weak social support, so the stress response intensifies and persists rather than resolving. A PA who screens for negative appraisal style and low perceived control can intervene early with coping-skill training or referral to behavioral health rather than wait for complications.
Coping Strategies and Health Outcomes
Problem-focused coping targets the stressor directly — information-seeking, treatment adherence, action planning — and is most effective when the situation is controllable. Emotion-focused coping regulates the emotional response through reappraisal, support-seeking, or relaxation and is adaptive when the stressor is uncontrollable, as in terminal illness or chronic disease. Maladaptive coping (avoidance, denial, substance use) predicts poorer adherence, slower wound healing, and higher readmission risk. Antonovsky's sense of coherence — comprehensibility, manageability, and meaningfulness — moderates the impact of stressors on health and is a useful framing for patient resilience, tying appraisal back to measurable clinical outcomes.
General Adaptation Syndrome Applied to Chronic Exam Stress
A PA-CAT candidate studying over several months illustrates how Selye's three stages unfold with a prolonged, repeating stressor. During the alarm phase, immediately after registering for the exam, sympathetic-adrenal-medullary activation produces tachycardia, sleep disruption, and heightened vigilance — useful short-term but costly if sustained. As study becomes routine, the candidate enters the resistance stage: cortisol remains elevated, blood pressure trends upward, and immune function subtly declines, yet outward function is maintained. Many candidates attribute fatigue and frequent colds to being busy rather than recognizing sustained HPA activation. If sleep, exercise, and social support remain inadequate, the exhaustion stage emerges in the final pre-exam weeks: depleted glycogen reserves, impaired concentration, emotional lability, and reactivation of latent viruses such as cold sores reflect failed adaptation. The PA-CAT behavioral science block tests this cascade because it mirrors clinical chronic-stress presentations. Recognizing the stage guides intervention: alarm-stage anxiety responds to reappraisal and planning; resistance-stage strain requires recovery practices including sleep hygiene, aerobic exercise, and social support; exhaustion-stage decline warrants reducing load and screening for depression. The same framework applies to patients facing chronic illness, caregiving, or poverty, making GAS a bridge from exam preparation to patient care.
A patient loses their job and, after several months, develops hypertension and recurrent infections. According to Selye's General Adaptation Syndrome, which stage best explains this presentation?
A student views an upcoming PA-CAT as a manageable challenge rather than a threat because they prepared for months. This best illustrates which Lazarus construct?
