AP Psychology Unit 5: Mental and Physical Health Notes

Introduction

Health and disorder are studied through interacting biological, psychological, social, and structural processes, with careful boundaries around classification and care.

This unit connects stress and well-being research to classification and treatment evidence. Its central skill is inference: decide whether evidence supports an observation, association, causal mechanism, professional category, or policy decision.

The course explains mental-health concepts without diagnostic checklists or individual recommendations. If course material raises a personal concern, use a trusted adult or qualified health professional; in the United States, call or text 988 for immediate crisis support.

Introduction to Health Psychology

How do psychological, biological, and social processes relate to health?

Short answer

Health reflects interacting physiology, appraisal, behavior, relationships, resources, and structural conditions, so a stress–health association never justifies blaming an individual.

The idea

Health psychology applies psychological science to health, illness, and health care. The biopsychosocial model treats biological processes, thoughts and behavior, relationships, material resources, and institutions as interacting levels. It is not a checklist in which each level contributes equally. The relevant pathway depends on the exposure, outcome, time scale, and population being studied.

A stressor is a demand or event; a stress response is the body’s and mind’s reaction. Appraisal matters because people evaluate both the demand and the resources available to address it. Sympathetic activation and the hypothalamic–pituitary–adrenal axis can mobilize energy during acute demand. Repeated or poorly recovered activation may relate to later outcomes through several routes, including sleep, behavior, immune processes, and continued exposure. A biomarker correlation alone does not establish that chain.

Problem-focused coping aims to change a manageable source of demand, while emotion-focused coping aims to regulate the response. Either can fit or fail depending on controllability and timing. Social support, income, discrimination, work conditions, access to care, and neighborhood resources shape exposure and options. Illness is not evidence that someone appraised poorly or failed to be resilient.

Biopsychosocial pathway linking exposure, appraisal, physiology, behavior, relationships, resources, and health outcomes — Health pathways cross biological and social levels
A health outcome can reflect several interacting pathways. The model connects levels instead of blaming a person or treating stress as a direct cause.

Association does not identify the pathway

What can a synthetic stress–sleep association establish?

Association does not identify the pathway dataset
Week	Reported demand score	Average sleep (hours)	Late work shifts
1	3	7.8	0
2	5	7.1	1
3	7	6.4	3
4	8	6	4
5	4	7.3	1

Analysis: Higher reported demand appears alongside shorter sleep in this tiny synthetic series. The pattern supports a negative association in these observations, not a conclusion that appraisal caused the sleep change.
Limitations: The values are invented, the sample is one short series, both key measures may contain error, and late shifts could influence demand and sleep.

Analyze a health pathway

Separate the stressor, appraisal, response, behavior, and outcome.
Identify biological, psychological, social, and structural contributors supported by evidence.
Match the causal claim to the study design.
Reject blame language and name access or resource constraints.

Keep these three ideas

Stressor, appraisal, and response are different constructs.
Acute activation can be adaptive while repeated exposure and poor recovery may carry costs.
Health outcomes cannot be reduced to individual coping.
