Revise Managing stress for Cambridge 9990 (3.4.3)

Coping refers to the cognitive and behavioural efforts made to manage specific external and/or internal demands that are appraised as taxing or exceeding the resources of the person. Lazarus and Folkman (1984) proposed a key distinction between two types of coping. Problem-focused coping involves taking direct action to tackle the source of stress. This might include planning, problem-solving, or seeking instrumental support to change the stressful situation itself. In contrast, emotion-focused coping aims to manage the emotional distress caused by the stressor, without changing the situation. This includes strategies like distraction, seeking emotional support, meditation, or reframing the problem in a more positive light. The effectiveness of each strategy often depends on whether the stressor is perceived as controllable.

Biofeedback is a technique that enables an individual to learn to control their involuntary physiological processes. It operates on the principle of operant conditioning. The individual is connected to a machine that provides real-time 'feedback' on a biological signal, such as muscle tension (electromyography, EMG), skin temperature, or heart rate. For example, a client with tension headaches might see a graph or hear a tone that changes as their forehead muscle tension increases or decreases. By trying different mental and physical strategies (e.g., thinking calming thoughts), the client learns which ones successfully reduce the tension. Through reinforcement (the desirable feedback), they gain conscious control over this physiological response, which can then be applied in stressful situations without the machine.

Relaxation techniques are a set of behavioural strategies designed to counteract the body's physiological stress response. One common method is Progressive Muscle Relaxation (PMR), developed by Edmund Jacobson. PMR involves systematically tensing and then releasing different muscle groups throughout the body, from the feet to the head. This process helps the individual become more aware of the physical sensation of tension and learn to achieve a deep state of relaxation voluntarily. Physiologically, this practice reduces the activity of the sympathetic nervous system (which drives the 'fight or flight' response) and increases the activity of the parasympathetic nervous system, leading to a decrease in heart rate, blood pressure, and muscle tension. It is a portable skill that can be used to manage acute stress.

Developed by Donald Meichenbaum, Stress Inoculation Training (SIT) is a cognitive-behavioural therapy that aims to 'inoculate' individuals against future stress. It is a proactive, multi-stage process. The first stage, Conceptualisation, involves the therapist and client creating a collaborative relationship and reframing the client's perception of stress. The second stage, Skills Acquisition and Rehearsal, is where the client learns a broad range of cognitive and behavioural skills, such as relaxation, problem-solving, and using positive self-talk to replace negative thought patterns. The final stage, Application and Follow-through, involves applying these newly learned skills to progressively more demanding stressors, first through imagery and role-play, and then in real-life situations. This gradual exposure builds confidence and resilience.
