Biological methods of stress management using drugs and biofeedback

Biological approaches to stress management focus on altering the body's physiological responses to stress. These methods include drug treatments and biofeedback, both of which aim to reduce the physical symptoms associated with stress.

Drug treatments for stress reduction

• Types of drugs - Two main categories of drugs are used to manage stress:
  1. Benzodiazepines (BZs) - These anti-anxiety medications enhance the effect of the body's natural calming chemical, gamma-aminobutyric acid (GABA), which slows down the activity of neurones in the central nervous system (CNS), promoting relaxation.
  2. Beta blockers - These drugs target the sympathetic nervous system (SNS), which is responsible for increasing heart rate, blood pressure, and levels of cortisol during stress. By reducing these responses, beta blockers help prevent stress-related health issues like weakened immunity and heart disease.
• Effectiveness:
  • Drugs act quickly to alleviate severe symptoms such as elevated blood pressure.
  • Research, such as a study by Kahn et al. (1986), demonstrated that BZs outperformed a placebo in reducing anxiety over a period of 8 weeks with around 250 participants.
• Limitations:
  • Drugs address only the symptoms of stress, not the underlying causes, and their effects last only as long as they are taken.
  • Side effects can include dizziness, fatigue, blurred vision, and altered sex drive.
  • Additionally, BZs carry a risk of dependency and withdrawal symptoms like heightened anxiety and tremors, so their use is often restricted to short-term periods, typically no longer than 4 weeks.

Biofeedback as a stress management tool

Biofeedback provides individuals with real-time data on internal bodily functions, such as heart rate or muscle tension, which are typically unnoticed.

The goal is to enable control over these processes through the following steps:

1. Attachment to a monitoring device that displays feedback on physical states like blood pressure or muscle tension.
2. Learning techniques to manage these states, including progressive muscle relaxation (tensing and relaxing muscle groups sequentially), meditation to clear the mind, or controlled breathing exercises.
3. Reinforcement of relaxation as a rewarding experience, encouraging repetition through a form of operant conditioning.
4. Application of these techniques in everyday stressful situations to manage responses effectively.

Effectiveness:

• Biofeedback has shown success in helping individuals, particularly younger people, manage stress-related conditions like migraines.
• A study by Attanasio et al. (1983) found that children and teenagers gained control over migraine symptoms and reported improved enthusiasm and positivity.

Research evidence - Budzynski et al. (1973):

• Method - Conducted a study on biofeedback with 18 participants suffering from tension headaches, in three groups:
  1. Group 1 received genuine biofeedback with muscle tension feedback via an electromyography (EMG) monitor using audible clicks (fewer clicks indicated relaxation).
  2. Group 2 received fake feedback.
  3. Group 3 was a control with no intervention.
• Results - After 8 weeks and a follow-up at 3 months, Group 1 showed the most significant reduction in muscle tension and headache frequency, alongside improved mental health indicators like reduced depression and health preoccupation.
• Evaluation:
  • The inclusion of a control group and fake feedback group confirmed the effectiveness of genuine biofeedback.
  • The small sample size limits generalisation, and results are specific to tension headaches, not other stress symptoms.

Cognitive approach through stress inoculation therapy

Cognitive methods focus on altering thought patterns that contribute to stress. Stress inoculation therapy (SIT) is a prominent technique in this category, designed to build resilience against stressors by preparing individuals mentally.

Phases of stress inoculation therapy

• Conceptualisation - Individuals work with a therapist to identify specific fears and concerns that trigger stress, gaining insight into their stress responses.
• Skills acquisition and rehearsal - Training focuses on developing coping strategies such as positive thinking and relaxation techniques to boost self-confidence and manage stress responses effectively.
• Application and follow-through - Individuals apply these skills in real-world scenarios, supported by the therapist, to ensure the techniques become second nature during stressful situations.
• Effectiveness - Developed by Meichenbaum (1985), SIT has proven effective for both short-term stressors, like preparing for a presentation, and long-term challenges, such as coping with chronic illness or significant life changes like divorce.

Evaluation of stress inoculation therapy

• Strengths - SIT encourages individuals to confront and understand the root causes of their stress, leading to more enduring coping mechanisms compared to symptom-focused methods.
• Limitations - The approach demands significant commitment, time, and personal insight, which may not suit everyone. Additionally, Meichenbaum's research primarily involved a specific demographic (white, middle-class individuals), limiting its applicability to broader populations.

The role of social support in managing stress

Social support plays a vital role in buffering the effects of stress by providing emotional, practical, and confidence-building assistance. It is suggested that strong social connections can mitigate the negative impact of stress on the immune system.

Types of social support

• Instrumental support - Involves practical help, such as assisting with groceries, household tasks, or providing financial aid, which alleviates stress related to time, money, or responsibilities.
• Emotional support - Includes gestures like hugs, listening, or empathising, often from close family and friends, which offer comfort and reduce emotional distress by making individuals feel valued and supported.
• Esteem support - Focuses on boosting confidence through encouragement and reinforcing personal strengths, helping individuals feel capable of handling stressful situations by enhancing self-worth.

Research on social support and health outcomes - Waxler-Morrison et al. (1991)

• Method - This natural experiment explored the impact of social support on survival rates among 133 women with breast cancer. Data on social networks, including the number of supportive friends and frequency of contact, was gathered via questionnaires and interviews, with medical records tracked over 4 years.
• Results - Women with stronger social support networks, including being married, employed, and having frequent friend interactions, showed higher survival rates.
• Conclusions - Social support appears to reduce stress, potentially improving immune function and contributing to better health outcomes in breast cancer patients.
• Evaluation:
  • This highlights a correlation between social support and improved survival, suggesting a protective role against stress.
  • Correlation does not imply causation; other factors may influence survival. The study's focus on women limits generalisation to other genders.

Strengths and weaknesses of different stress management techniques

Each stress management approach has unique advantages and drawbacks, influencing its suitability for different individuals and contexts.

Assessing cognitive and social approaches

• Stress inoculation therapy (SIT):
  • Strengths - Targets underlying thought processes, offering lasting benefits for managing stress through skill development.
  • Weaknesses - Requires dedication and may not be effective for everyone due to its intensive nature and demographic-specific research base.
• Social support:
  • Strengths - Naturally integrated into daily life, provides multifaceted assistance (emotional, practical, esteem), and may enhance immune function.
  • Weaknesses - Effectiveness depends on the quality and availability of support networks; benefits are harder to measure and control compared to structured interventions.
