Input: Fifteen studies (two with long term follow-up studies) were identified examining a range of interventions. In terms of main findings, twelve studies evaluated brief trauma focused cognitive behavioural interventions (TF-CBT). TF-CBT was more effective than a waiting list intervention (6 studies, 471 participants; SMD -0.64, 95% CI -1.06, -0.23) and supportive counselling (4 studies, 198 participants; SMD -0.67, 95% CI -1.12, -0.23). Effects against supportive counselling were still present at 6 month follow-up (4 studies, 170 participants; SMD -0.64, 95% CI -1.02, -0.25). There was no evidence of the effectiveness of a structured writing intervention when compared against minimal intervention (2 studies, 149 participants; SMD -0.15, 95% CI -0.48, 0.17). There was evidence that individual TF-CBT was effective for individuals with acute traumatic stress symptoms compared to both waiting list and supportive counselling interventions. The quality of trials included was variable and sample sizes were often small. There was considerable clinical heterogeneity in the included studies and unexplained statistical heterogeneity observed in some comparisons. This suggests the need for caution in interpreting the results of this review. Additional high quality trials with longer follow up periods are required to further test TF-CBT and other forms of psychological intervention.
Output:

However, previous reviews have found that single session individual interventions and interventions provided to all have not been effective at preventing PTSD. A range of other forms of intervention have been developed to try to reduce psychological distress for individuals exposed to trauma. This review evaluated the results of 15 studies that tested a diverse range of psychological interventions aimed at treating acute traumatic stress problems. There was evidence to support the use of trauma focused cognitive behavioural therapy with such individuals, although there were a number of potential biases in identified studies which means the results should be treated with some caution. Further research is required to evaluate longer terms effects of TF-CBT, to explore potential benefits of other forms of intervention and to identify the most effective ways of providing psychological help in the early stages after a traumatic event.
