    Cardiac surgery can be traumatic and stressful, and as a result many people experience psychological difficulties following treatment. Post Traumatic Stress Disorder (PTSD) is now being investigated in post-surgical populations with surprising results. Prevalence rates for PTSD following cardiac surgery range from 10% to 38%. Current knowledge regarding PTSD in post-surgical populations is limited, and many studies are concerned with risk factors and prevalence rates, and have not investigated the effects of psychological interventions. Thus, the magnitude of improvement in long-term outcomes resulting from the use of preventative interventions is unclear. With this in mind, the current study was created to investigate the effect of a brief psychoeducational intervention to prevent the symptoms of PTSD, and improve the adaptive coping behaviours of people who have survived cardiac surgery. This research question was addressed as a pilot study and utilised a randomised, controlled design that enlisted 33 participants awaiting cardiac surgery at a single site. The effectiveness of the intervention was evaluated by comparing it to the standard treatment patients are currently offered upon admission to the cardiac ward. Standardised self-report measures were collected during baseline, treatment and once at two-week follow-up. Results showed that, compared to pre-treatment levels, the majority of participants who received the intervention demonstrated a reduction in PTSD symptoms and an increase in adaptive coping behaviours related to recovery after cardiac surgery. Findings are interpreted in terms of previous literature and implications are discussed according to theory, research and clinical practice. Limitations of the study are outlined and recommendations for future research are discussed. Suggestions for future research include evaluating the effectiveness of the manual in a larger, more diverse group of people, extending follow-up periods and utilising more rigorous measures. Overall, preliminary findings support the effectiveness of the Coping After Cardiac Surgery Manual in treating people who have undergone cardiac surgery.
