Introduction
This essay examines the case of Layla, a 21-year-old university student experiencing intense anxiety in social situations, through a psychological lens. Drawing on diagnostic criteria, the biopsychosocial model, maintenance factors, and treatment recommendations, the analysis aims to identify her likely diagnosis, explain her difficulties from multiple perspectives, outline how her issues persist, and suggest an evidence-based intervention. This structure aligns with key concepts from psychology lectures, particularly those in Weeks 3 and 5, to provide a comprehensive understanding of social anxiety in a university context. By integrating these elements, the essay highlights the interplay of factors in mental health and the importance of tailored treatments.
Diagnosis: Social Anxiety Disorder
The most appropriate diagnosis for Layla is Social Anxiety Disorder (SAD), as per DSM-5 criteria. This is justified by her marked fear or anxiety in social situations where she might be scrutinised, such as meeting new people or group conversations, fearing she will act in a way that leads to negative evaluation (American Psychiatric Association, 2013). She experiences physical symptoms like heart racing and trembling, which she interprets as visible signs of anxiety, and these persist for over six months. Avoidance behaviours, such as declining invitations and staying peripheral at events, significantly impair her social functioning, and the anxiety is not better explained by another condition, like generalised anxiety disorder, since it is specific to social contexts. Her family history and early teasing align with risk factors, supporting this diagnosis over alternatives like avoidant personality disorder, which typically involves broader interpersonal avoidance.

Biopsychosocial Perspectives on Layla’s Difficulties
From a biological perspective, Layla’s anxiety may stem from genetic predispositions, as evidenced by her sister’s anxiety struggles, suggesting heritability in anxiety disorders (Stein and Stein, 2008). Neurobiologically, imbalances in neurotransmitters like serotonin or heightened amygdala activity could amplify her physiological responses, such as heart racing, in social threats (as discussed in Week 3 lectures on biological bases of anxiety).
Psychologically, cognitive biases play a key role; Layla’s self-monitoring and fear of saying something “stupid” reflect negative self-appraisals and attentional focus on internal sensations, leading to distorted interpretations of social cues (Clark and Wells, 1995). This aligns with Week 3 content on cognitive models, where such thoughts perpetuate anxiety cycles.
Socially, environmental factors like early high school teasing for being “quiet” likely reinforced her shyness, fostering avoidance and isolation. University settings, with frequent social demands, exacerbate this, while her reliance on safety behaviours (e.g., checking her phone) limits positive interactions, increasing feelings of loneliness.
Within the biopsychosocial model, these factors interact dynamically: biological vulnerabilities (e.g., genetic sensitivity) heighten psychological responses to social stressors, which in turn lead to avoidance behaviours that socially isolate her, further entrenching biological arousal patterns (Engel, 1977). For instance, genetic predispositions may make her more reactive to teasing, triggering cognitive biases that maintain social withdrawal, illustrating how no single factor operates in isolation but rather compounds the others in a feedback loop.

Maintenance of Layla’s Difficulties
Layla’s difficulties are maintained through mechanisms outlined in Week 5 models, particularly Clark and Wells’ (1995) cognitive model of social phobia. Self-focused attention heightens her awareness of bodily sensations (e.g., trembling), which she misinterprets as evidence of visible anxiety, increasing distress. Safety behaviours, like avoiding conversations or using her phone, prevent disconfirmation of fears, as they reduce immediate anxiety but reinforce beliefs about social incompetence. Post-event processing, where she ruminates on perceived failures, sustains negative self-images. These cognitive and behavioural cycles, interacting with avoidance, perpetuate isolation and anxiety, aligning with Week 5 discussions on maintenance in anxiety disorders.

Recommended Treatment: Cognitive Behavioural Therapy
One evidence-based treatment from Week 5 is Cognitive Behavioural Therapy (CBT) for SAD, as recommended by NICE guidelines (National Institute for Health and Care Excellence, 2013). It should be effective according to Clark and Wells’ model by targeting cognitive biases through exposure to feared situations, challenging negative interpretations, and reducing safety behaviours, thereby breaking maintenance cycles and building social confidence. However, a limitation is potential dropout due to initial anxiety increases during exposure, raising ethical considerations around informed consent and ensuring therapist support to avoid harm.

Conclusion
In summary, Layla’s case exemplifies Social Anxiety Disorder, explained through interacting biopsychosocial factors and maintained by cognitive-behavioural cycles. Recommending CBT addresses these effectively, though with ethical caveats. This analysis underscores the value of integrated models in psychology for understanding and treating anxiety, with implications for supporting students like Layla to foster better social integration and mental well-being. Further research could explore personalised interventions to mitigate limitations.
