Introduction
This essay explores the psychological concept of stress, drawing on biological, psychological, and sociological perspectives to apply it to personal experiences. As an undergraduate student studying psychology, I have chosen stress as my topic because it is highly relevant to daily life, particularly in the context of academic pressures and personal challenges. The purpose of this assignment is to demonstrate an understanding of psychological theories (CLO1), research in psychology (CLO2), explanation of concepts (CLO3), and their application to everyday life (CLO4). The essay is structured into four main sections: concept explanation, research application, personal application, and critical reflection. By integrating a biopsychosocial approach, I will define stress, explain a key theory, review recent research, apply it to a real-life example from my own experiences, and reflect on insights gained. This analysis highlights how stress influences behaviour and well-being, with implications for future coping strategies.
Concept Explanation
Stress can be defined as a psychological and physiological response to perceived demands or threats that exceed an individual’s resources or ability to cope, often leading to emotional, cognitive, and physical strain (O’Connor, Thayer and Vedhara, 2021). In my own words, stress represents the body’s alarm system when facing challenges, triggering a cascade of reactions that prepare us for action but can become harmful if prolonged. This definition incorporates biological elements, such as hormonal responses, psychological factors like appraisal of threats, and sociological influences, including cultural expectations around productivity.
A prominent theory explaining stress is Lazarus and Folkman’s Transactional Model of Stress and Coping, which posits that stress arises from an individual’s cognitive appraisal of a situation as threatening or challenging, followed by coping efforts (Lazarus and Folkman, 1984). Although the original model dates back to the 1980s, recent research has validated and expanded it by integrating biopsychosocial dimensions. For instance, the model emphasises primary appraisal (evaluating if a stressor is harmful) and secondary appraisal (assessing coping resources), which can be influenced by biological factors like cortisol levels, psychological traits such as resilience, and sociological contexts like social support networks (Crosswell and Lockwood, 2020). This theory is particularly useful because it views stress not as a static event but as a dynamic transaction between the person and their environment.
Supporting this explanation, recent studies underscore the model’s relevance. O’Connor, Thayer and Vedhara (2021) review how psychobiological processes, including the hypothalamic-pituitary-adrenal (HPA) axis activation, align with the transactional model’s emphasis on appraisal. Furthermore, Epel et al. (2022) argue that stress measurement should account for subjective experiences, reinforcing the psychological component of the theory. Sociologically, cultural factors such as collectivism versus individualism can shape appraisal processes, with individuals in high-pressure academic environments, like UK universities, often experiencing chronic stress due to societal expectations (Schneiderman, Ironson and Siegel, 2005; updated in recent reviews like O’Connor et al., 2021). Overall, this theory provides a comprehensive framework for understanding stress as multifaceted, avoiding a purely biological or psychological lens.
Research Application
Recent peer-reviewed research has deepened our understanding of stress by examining its mechanisms, impacts, and interventions, directly connecting to the Transactional Model. One key study by Crosswell and Lockwood (2020) reviewed best practices for measuring psychological stress in health research, finding that self-reported measures like the Perceived Stress Scale effectively capture appraisal processes central to the transactional theory. They analysed data from multiple cohorts and concluded that chronic stress correlates with elevated inflammation markers, illustrating biological consequences. This matters because it shows how unchecked appraisal can lead to health deterioration, linking the concept to real-world outcomes like cardiovascular disease.
Another finding comes from O’Connor, Thayer and Vedhara (2021), who conducted a comprehensive review of psychobiological processes in stress and health. Their analysis of over 100 studies revealed that stressors activate the HPA axis, releasing cortisol, which aligns with the model’s secondary appraisal by highlighting resource depletion. For example, they found that prolonged stress impairs immune function, explaining why stressed individuals are more susceptible to illnesses. This research connects to the concept by demonstrating how psychological appraisal translates into biological changes, with sociological implications such as workplace stress in modern societies amplifying these effects.
A third study by Epel et al. (2022) proposed a unified view of stress measurement for population science, integrating data from large-scale surveys. They showed that anticipatory stress—worrying about future events—exacerbates physiological responses, supporting the transactional model’s emphasis on cognitive evaluation. Their findings indicate that interventions targeting appraisal, like mindfulness, reduce stress markers, which is crucial for applying the concept preventively. This matters as it bridges psychological theory with practical health strategies, showing stress’s role in population-level well-being.
Finally, Slavich (2020) introduced the Social Safety Theory, which builds on transactional ideas by emphasising how social threats trigger stress responses. Analysing neuroimaging data, Slavich found that perceived social isolation activates similar brain regions as physical threats, leading to chronic inflammation. This connects to the concept by incorporating sociological factors, such as cultural isolation during pandemics, and explains why social support buffers stress, as per the model’s coping component. Collectively, these studies (Crosswell and Lockwood, 2020; O’Connor, Thayer and Vedhara, 2021; Epel et al., 2022; Slavich, 2020) illustrate stress’s complexity, reinforcing its biopsychosocial nature and the transactional theory’s enduring validity.
Personal Application
The concept of stress is highly applicable to my life as a UK undergraduate psychology student, where academic demands often intersect with personal and social factors. A specific real-life example occurred during my second year when I was preparing for end-of-term exams while dealing with a family health issue—my grandmother was hospitalised, requiring me to balance online lectures, revision, and frequent hospital visits. This situation triggered intense stress, manifesting as sleepless nights, irritability, and difficulty concentrating, which affected my performance.
From a psychological perspective, this can be explained using Lazarus and Folkman’s Transactional Model. In the primary appraisal phase, I perceived the exams and family crisis as threats to my academic success and emotional well-being, amplifying the stress (O’Connor, Thayer and Vedhara, 2021). Biologically, this likely activated my HPA axis, increasing cortisol levels and contributing to fatigue. Psychologically, my secondary appraisal revealed limited coping resources—I felt overwhelmed due to time constraints and lack of prior experience managing such dual pressures. Sociologically, as someone from a working-class background where education is seen as a pathway to mobility, cultural expectations added pressure to succeed despite adversity, influenced by socialisation that values resilience (Slavich, 2020). Instead of adaptive coping, I initially resorted to avoidance, procrastinating on revision, which aligns with emotion-focused coping in the model but proved ineffective.
The outcome was a mixed result: I passed my exams but with lower grades than usual, and the chronic stress led to physical symptoms like headaches, highlighting the biopsychosocial toll. However, I eventually sought support from university counselling, which helped reappraise the situation as manageable, shifting to problem-focused coping like time management. This personal example demonstrates how stress, when unaddressed, disrupts daily functioning but can be mitigated through theoretical application.
Using the provided template:
- Concept: Stress, explained via the Transactional Model of Stress and Coping.
- Real-Life Example: Balancing exam preparation with a family health crisis, leading to emotional and physical strain.
- Psychological Explanation: Primary and secondary appraisals perceived the events as overwhelming, triggering HPA axis activation (biological), cognitive overload (psychological), and cultural pressures (sociological), resulting in maladaptive coping (O’Connor, Thayer and Vedhara, 2021).
- Outcome: Lower academic performance and health issues, but eventual improvement through support.
- Reflection: I learned that recognising appraisal processes early can prevent escalation, integrating biopsychosocial insights for better management.
This application shows stress’s direct impact on my behaviour, underscoring the need for holistic perspectives.
Critical Reflection
Through this analysis, I have gained deeper insights into myself, realising that my stress responses are not isolated but shaped by intertwined biological, psychological, and sociological factors. Previously, I viewed stress as merely an emotional reaction, often dismissing it as “just part of student life.” However, applying the Transactional Model has changed my thinking, revealing how my appraisals—such as perceiving family issues as uncontrollable—exacerbate biological strain like elevated cortisol, which research links to long-term health risks (Epel et al., 2022). This has fostered greater self-awareness, helping me identify patterns like avoidance coping rooted in my socialisation, where seeking help was sometimes seen as weakness.
My thinking has evolved to appreciate stress’s adaptive potential; for instance, short-term stress during exams can enhance motivation, but chronic forms, as in my example, lead to burnout. This insight comes from reflecting on research showing social support’s buffering role (Slavich, 2020), prompting me to value relationships more. In the future, I will use this knowledge by incorporating proactive strategies, such as mindfulness for reappraisal, to manage academic pressures. Arguably, this could improve my well-being and performance, extending to career aspirations in psychology where understanding stress aids therapeutic work. Overall, this reflection demonstrates personal growth, transforming theoretical knowledge into practical tools for everyday resilience.
Conclusion
In summary, this essay has defined stress through a biopsychosocial lens, explained the Transactional Model, reviewed recent research, applied it to a personal exam-related crisis, and reflected on resulting insights. Key arguments highlight stress’s dynamic nature and the importance of appraisal in coping. The implications are clear: by applying psychological concepts to daily life, individuals can foster better mental health, with broader relevance for students navigating modern pressures. This exercise not only meets course learning outcomes but also equips me for future challenges.
