PTSD Assessment: Private PTSD and Complex PTSD Diagnosis for Adults

Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after experiencing or witnessing a frightening, life-threatening, or deeply distressing event. Complex PTSD (C-PTSD) develops in a similar way, but is more often linked to prolonged or repeated trauma – such as ongoing abuse, domestic violence, or events experienced in childhood.¹,²

A PTSD assessment is used to determine whether your symptoms are consistent with PTSD or Complex PTSD, while also ruling out other conditions such as anxiety, depression, or dissociative disorders. Taking a PTSD test may bring you a sense of clarity about what you’ve been experiencing and offer guidance on the next steps to take. Private PTSD assessments are available in person in London and online for adults across the UK.
