Stress: Appraisal, Types, and Sources

Stress is a universal experience and one of the most researched topics in health psychology.
It occurs when our capacity to adapt to inner and outer demands is overwhelmed, leading to physiological and emotional reactions and thoughts/behaviours about coping.
Stress is subjective: it is in the eye of the beholder. People can experience different levels of stress in response to the same event.
- Example: a roller coaster may be exciting for some and stressful for others.
Core concept: stress appraisal determines how we perceive and respond to events. Appraisal involves evaluating both the situation and our ability to cope with it.
Appraisal determines whether a situation is threatening, benign, or irrelevant, and this appraisal influences coping responses.
The appraisal process consists of two forms that interact:
- Primary appraisal
- Secondary appraisal
Both forms involve emotional forecasting: predicting the feelings the situation will produce (primary) and the likely emotional impact of each potential response (secondary).
The two forms are not mutually exclusive; they interact to complete the appraisal process.
The model discussed here is Lazarus' transactional model of stress.

Primary appraisal: assess whether the situation is benign, stressful, or irrelevant.
Example (Deborah): applied for a full-time job, wasn’t offered the position. Primary appraisal would classify this as stressful for Deborah.
Secondary appraisal: evaluate options and decide how to respond.
- Deborah might: apply for several jobs, seek guidance to improve her CV, or consider other coping strategies.
Prior experience or exposure provides a frame of reference for possible options and actions.
If we have experienced similar situations before, we can more readily move into secondary appraisal (coping) more automatically.
Both stages involve emotional forecasting of possible feelings and the likely impact of each response.

Harm or loss: damage has already occurred.
- Examples: the death of a loved one, breakup of a relationship, not achieving a goal, or environmental harm.
- Harm or loss can also include more everyday events such as losing a parking space or finding a desired product out of stock.
Threat: anticipation of harm or loss; damage has not yet occurred.
- Examples: upcoming exam, potential breakup of a relationship, or anticipating regret when choosing a cake in a café.
Challenge: an event or task that is positive overall but still stressful and demanding.
- Examples: dating again after a long-term relationship (confronting but can lead to growth), landing a new job (stressful but learning opportunities and new skills).
Note: stress spans a spectrum from significant life events to everyday challenges; even positive events can be stressful.

Change or life events: noticeable alterations in living circumstances that require readjustment.
- Examples: getting married, getting divorced, getting fired, moving countries.
- These changes can be negative or positive.
Social Readjustment Rating Scale (Holmes & Rahe): a tool to quantify exposure to stressful life events by assigning scores.
- It categorizes events and assigns a numeric score representing stress intensity.
- Examples:
- Death of a spouse: $100$
- Marriage: $50$
- Trouble with the in-laws: $29$
Acculturative stress: stress from adapting to a new culture when moving to a different country with different customs.
- This involves not knowing culture, norms, or where things are, and represents a major life stressor during adjustment.
Catastrophes: mass-level stressors often involving loss or harm.
- Natural catastrophes: floods, fires, hurricanes, earthquakes.
- Human catastrophes: war and other large-scale crises.
Daily hassles: low-level, everyday irritants that accumulate to affect stress levels.
- Examples: losing car keys, a flat battery when you need to make a call, being stuck in a traffic jam while running late.

Developed by Holmes and Rahe to quantify the level of stress associated with life events.
Provides a numerical approach to assessing how stressful a given life change may be for an individual.
Example scores (stress level ranking):
- Death of a spouse: $100$
- Marriage: $50$
- Trouble with in-laws: $29$
Purpose: to quantify exposure to stressful events and estimate potential impact on well-being.

Acculturative stress occurs when adapting to a culture different from one's own.
- Involves unfamiliar social norms, language, systems, and daily routines.
The adjustment phase can be prolonged and challenging, contributing to overall stress levels.
Major life transitions (e.g., marriage, divorce, relocation) can be positive or negative but are inherently stress-inducing due to required readjustments.

Catastrophes (natural or human) affect large populations and are typically associated with widespread loss and harm.
Daily hassles are small-scale but frequent stressors that cumulatively impact well-being.

Stress is the challenge to cope with inner and outer demands; the perceived level of stress is subjective and can vary across individuals.
Primary appraisal determines relevance and threat level of the situation.
Secondary appraisal determines coping options and response strategies.
The appraisal process emphasizes the role of cognitive evaluation in stress, aligning with cognitive-behavioral approaches to coping.
Coping strategies may be seen as efforts to reframe or modify the situation or one’s response to it (e.g., seeking guidance, improving skills, seeking support).
Prior experience shapes expectations and available coping options, illustrating the role of learning and memory in stress responses.
Real-world relevance: understanding appraisal can inform stress management interventions, workplace accommodations, and mental health support.

Subjectivity of stress underscores the importance of validating others' experiences rather than assuming universal reactions to events.
Recognizing that even positive events can induce stress supports a balanced view of well-being and resilience.
Practical implication: interventions should account for individual appraisals, provide coping resources, and reduce unnecessary stress through planning and social support.

Aligns with the biopsychosocial model: biological reactions to stress, cognitive appraisal, and social/environmental factors.
Highlights the transactional nature of stress, where person-environment interactions determine outcomes.
Demonstrates the importance of coping research and stress management in health psychology.

Stress arises when demands exceed our coping abilities, but its intensity is subjective.
The Lazarus transactional model involves two interacting appraisals:
- Primary appraisal: is the situation benign, stressful, or irrelevant?
- Secondary appraisal: what are my options, and how should I respond?
Three core types of stress to distinguish: harm/loss, threat, and challenge.
Stress sources range from major life changes and acculturation to catastrophes and daily hassles.
Quantifying stress via the SRRS provides a numerical sense of life-event stress, though individual impact varies.
Understanding appraisal and coping supports better stress management in everyday life and broader health contexts.
