Objective: Combat Stress, a UK national charity for veterans with mental health problems, has been funded by the National Health Service (NHS) to provide a national specialist service to deliver treatment for post-traumatic stress disorder (PTSD). This paper reports the efficacy of a PTSD treatment programme for UK veterans at 6 months follow-up. Design: A within subject design. Setting: UK veterans with a diagnosis of PTSD who accessed Combat Stress. Participants: 246 veterans who received treatment between late 2012 and early 2014. Intervention: An intensive 6-week residential treatment programme, consisting of a mixture of individual and group sessions. Participants were offered a minimum of 15 individual trauma-focused cognitive behavioural therapy sessions. In addition, participants were offered 55 group sessions focusing on psychoeducational material and emotional regulation. Main outcome measures: Clinicians completed measures of PTSD and functional impairment and participants completed measures of PTSD, depression, anger and functional impairment. Results: We observed significant reductions in PTSD scores following treatment on both clinician completed measures (PSS-I: -13.0, 95% CI -14.5 to -11.5) and self-reported measures (Revised Impact of Events Scale (IES-R): -16.5, 95% CI -19.0 to -14.0). Significant improvements in functional impairment were also observed (eg, Health of the Nation Outcome Scales (HONOS): -6.85, 95% CI -7.98 to -5.72). There were no differences in baseline outcomes between those who completed and those who did not complete the programme, or post-treatment outcomes between those we were able to follow-up at 6 months and those lost to follow-up. Conclusions: In a naturalistic study we observed a significant reduction in PTSD scores and functional impairment following treatment. These improvements were maintained at 6 month follow-up. Our findings suggest it may be helpful to take a closer look at combining individual trauma-focused cognitive behaviour therapy and group sessions when treating veterans with PTSD. This is the first UK study of its kind, but requires further evaluation.
