Access to therapy for people with post-traumatic stress disorder (PTSD) is limited. A study assessed an online version of cognitive behavioural therapy (CBT) for people with the condition. In those with mild-to-moderate PTSD, the online approach was as effective as, and cheaper than, the same therapy given face-to-face.

PTSD is a mental health condition triggered by frightening or distressing events. CBT with a trauma focus (CBT-TF) is a talking therapy that can help people with PTSD come to terms with a traumatic event. This therapy, given face-to-face, is recommended as a first-line treatment in the UK. But waiting lists can be up to a year.

Researchers explored whether CBT-TF, provided online and with support from a therapist, is effective. They compared it with face-to-face CBT-TF in people with mild-to-moderate PTSD.

People who received online CBT-TF benefitted as much as those who received face-to-face therapy. They appreciated the flexibility that online therapy provided. But some said they would have preferred the longer face-to-face sessions. The researchers say supported online therapy can provide treatment sooner than face-to-face therapy, but it is not appropriate for everyone.
