Welcome to Your Guide on Stress: Measurement, Individual Differences, and Coping!
In our previous look at stress, we explored what it is and how it affects the body. Now, we are diving into the "how" and the "who." How do psychologists actually measure something as invisible as stress? Why does one person thrive under pressure while another feels overwhelmed? And most importantly, how can we manage it? This chapter is part of the Paper 3 Option 2 section and is essential for understanding the psychological side of health.
1. Measuring Stress: How Do We Put a Number on It?
Psychologists use two main ways to measure stress: self-report scales (where you tell the researcher how you feel) and physiological measures (where your body does the talking).
A. Self-Report Scales
The Social Readjustment Ratings Scale (SRRS)
This scale focuses on life changes—major events that require us to make a big adjustment. Think of things like moving house, starting a new job, or experiencing a bereavement.
• Each event is given a score in Life Change Units (LCUs).
• The higher your total score over a year (e.g., a score of \( 300+ \)), the higher the risk of stress-related illness.
• Common Mistake: Don't forget that even "happy" events like a wedding or Christmas carry LCU points because they still require "readjustment"!
The Hassles and Uplifts Scale (HSUP)
Some psychologists believe it’s not the big events that get us, but the "death by a thousand cuts."
• Daily Hassles: The small, annoying things like losing your keys, traffic jams, or a broken Wi-Fi connection.
• Uplifts: The small positive things that "buffer" stress, like a nice cup of coffee or a compliment from a friend.
• Research often shows that daily hassles are actually a better predictor of illness than major life changes!
B. Physiological Measures
Skin Conductance Response (SCR)
When we are stressed, our Sympathetic Nervous System kicks in (the "fight or flight" mode). One side effect is that we sweat more—even if it's just a tiny amount on our fingertips.
• Sweat contains salt, which conducts electricity.
• By placing electrodes on the fingers, researchers can measure how easily a small electric current passes through the skin.
• The more you sweat, the higher the "conductance," indicating higher stress levels.
Quick Summary: Self-reports (SRRS and HSUP) are great for looking at the causes of stress, while SCR is great for measuring the immediate physical reaction to stress without relying on a person's memory.
2. Individual Differences: Why Are We All Different?
Have you ever noticed that some people seem to love high-pressure environments? Psychologists look at personality types and hardiness to explain this.
A. Personality Types
Type A: These individuals are highly competitive, time-urgent (always in a rush), and can be hostile or easily angered. They are more likely to experience stress-related heart problems.
Type B: The opposite of Type A. They are relaxed, patient, and easy-going. They tend to have much lower levels of stress-related illness.
Type C: These people tend to suppress their emotions (especially "negative" ones like anger) and strive to please others. Some research has linked this personality type to a higher risk of cancer due to the impact of suppressed stress on the immune system.
B. Hardiness
A "Hardy Personality" acts like a shield against stress. You can remember the three traits of hardiness using the 3 Cs:
1. Commitment: They are deeply involved in what they do (work, family, hobbies) and see life as having purpose.
2. Challenge: They see change and stress as an opportunity to grow, rather than a threat to their safety.
3. Control: They believe they are in charge of their own lives and can influence their outcomes, rather than being victims of fate.
Analogy: Think of a "Hardy" person as a sturdy oak tree. While a storm (stress) might blow some leaves off, the tree's deep roots and strong trunk keep it standing.
3. Managing and Coping with Stress
If stress is unavoidable, how do we fix it? We can use biology, psychology, or social support.
A. Biological Treatments
Drug Therapy:
• Benzodiazepines (BZs): These slow down the Central Nervous System by increasing the effect of a chemical called GABA (which tells the brain to "chill out").
• Beta-blockers: These work on the body rather than the brain. They block the effects of adrenaline, lowering heart rate and blood pressure. They are great for "performance anxiety" (like before a speech).
Biofeedback:
This is a clever way of using technology to gain "voluntary control" over involuntary body functions. A patient is hooked up to a monitor (like an SCR or heart rate monitor). When they see their heart rate go down (perhaps by breathing deeply), the machine gives them a "reward" like a beep or a green light. Over time, the person learns to control their physical stress response without the machine.
B. Psychological Treatments
Stress Inoculation Therapy (SIT):
Think of this like a "vaccine" for stress. You get a "weak dose" of stress in therapy so you can handle the "real thing" later. It has three phases:
1. Conceptualisation: Working with a therapist to identify what causes your stress.
2. Skill acquisition: Learning coping skills, like relaxation or positive self-talk.
3. Application: Practicing these skills in increasingly stressful (but safe) situations.
C. Social Support
Sometimes, we just need other people. There are three types of social support:
• Instrumental: Practical help (e.g., a friend giving you a lift to the hospital).
• Emotional: Giving someone a "shoulder to cry on" or making them feel cared for.
• Esteem: Boosting a person's confidence and making them feel capable of handling the stress.
D. Gender Differences in Coping
Do men and women cope differently? Research suggests a general pattern:
• Men often use problem-focused coping. They try to "fix" the source of the stress (e.g., if the car breaks down, they focus on getting it repaired).
• Women often use emotion-focused coping. They try to manage the feelings associated with the stress (e.g., talking to a friend about how stressed the broken car makes them feel).
Note: Don't worry if this seems like a stereotype; in reality, most people use a mix of both!
Key Takeaways for Revision
• Measurement: SRRS = Life Changes; HSUP = Daily Hassles; SCR = Physical sweat response.
• Personality: Type A = Competitive/Hostile; Type B = Relaxed; Type C = Emotionally suppressed; Hardiness = 3 Cs (Commitment, Challenge, Control).
• Management: Drugs (BZs/Beta-blockers) and Biofeedback address the body. SIT (Inoculation) addresses the mind. Social Support (Instrumental/Emotional/Esteem) addresses the environment.
• Gender: Men tend toward "Problem-focused" and women toward "Emotion-focused" coping.
