CPT has been shown to be effective in treating PTSD and related symptoms (e.g., depression) in numerous studies (click here for a summary of CPT research). At this time, this has included more than 10 randomised trials and numerous open trials. This literature demonstrates the large range of clients who can be helped by CPT, including survivors of interpersonal trauma (from both childhood and adulthood experiences), veterans, active duty military personnel, as well as those who have experienced single-incident type traumas. It is worth noting that CPT has been used successfully with individuals from non-English speaking backgrounds, whether this is with refugees in a Western treatment setting, or with clients in their country of origin. Treatment guidelines both here in Australia and overseas indicate that trauma-focussed cognitive-behavioural methods such as CPT should be the front-line treatment of choice.
