Ontological insecurity in the post-covid-19 fallout: using existentialism as a method to develop a psychosocial understanding to a mental health crisis.

In the wake of the Covid-19 pandemic we are witnessing a significant rise in mental illness diagnosis and corresponding anti-depressant prescription uptake. The drug response to this situation is unsurprising and reinforces the dominant role (neuro)biology continues to undertake within modern psychiatry. In contrast to this biologically informed, medicalised approach, the World Health Organisation (WHO) issued a statement stressing the causal role of psychological and social factors.Using the concept of ontological insecurity, contextualised within the WHO guidance, the interrelation of psychological and social factors is illuminated, and a psychosocial framework is produced as a means of understanding the mental health consequence of the post-Covid-19 fallout.The psychosocial framework generated provides a rationale to revise and reprioritise how we engage with the biopsychosocial model that is intended to underpin modern psychiatry. This framework establishes a connection between psychological and social theory which are too often addressed as disparate terrains within mental health services and policy creation.
