It is widely recognised that the population of people held in immigration detention have very high levels of trauma and high rates of mental illness.
“Research suggests that a high proportion of immigration detainees display clinically significant levels of depression, PTSD and anxiety, as well as intense fear, sleep disturbances, profound hopelessness, self-harm and suicidal ideation.”[1]
Rates of mental ill health including depression, anxiety and PTSD, are far higher among people in detention than in the wider population. A systematic review of the existing international clinical literature on this topic by Verhülsdonk and colleagues (2021)[2] included four studies of people in immigration detention in the UK. The researchers found overall that three quarters of people in immigration detention experienced depression, more than half experienced anxiety and almost half experienced post-traumatic stress disorder.

The main symptom of generalised anxiety disorder (GAD) is “feelings of stress or worry that affect your daily life and are difficult to control.” – NHS website
