There is now growing evidence to suggest that the experience of psychosis may be so traumatic for some that it can lead to Post Traumatic Stress Disorder (PTSD)-type symptoms or post-psychotic trauma symptoms (PPTS). There is, however, less knowledge about what psychological interventions may be helpful in reducing these symptoms. Evidence from the literature, to date, suggests that of the seven studies that have addressed this issue only four were randomized controlled trials (RCTs). However, all these studies included less than 100 patients with the vast majority reporting positive results. Overall, it seems that although cognitive-behavioural treatment (CBT)-based psychological interventions appear to be efficacious in the treatment of PPTS, the studies are too small to draw any firm conclusions and should be subjected to larger good-quality RCTs. Further research will also need to establish the role of mediating variables such as shame and depression in the treatment of PPTS.
