    INTRODUCTION AND OBJECTIVES: There is significant delayed psychological morbidity and negative psycho-social impact following snakebite. However, no psychological support is provided to victims. We aimed to develop and assess the effectiveness of a brief intervention which can be provided by non-specialist medical officers aimed at reducing psychological morbidity. METHODS: In a single blind clinical trial at Polonnaruwa Hospital, 187 snakebite victims were randomised into three arms. One arm received no psychological intervention (Group A; n=59; control). Group B (n=60) received psychoeducation at discharge from hospital. Group C (n=68) received psychoeducation and a.second intervention one month later based on cognitive behavioural principles. All patients were assessed six months after discharge from hospital using standardised tools for presence of psychological symptoms and level of functioning. RESULTS: Compared with Group A, there was a significant reduction in anxiety symptoms measured by the Hopkins Psychiatric Symptom check list (16.9% vs. 5.9%, p=0.047, Chi-Squared test) and a non-significant trend towards improvement in the level of functioning measured by the Sheehan Disability inventory (6.47 vs. 4.69) in Group C, but not in Group B. There was no difference in rates of depression and post-traumatic stress disorder (PTSD) between the three groups. CONCLUSIONS: Our preliminary findings suggest that brief psychological interventions which include psychoeducation plus cognitive behavioural therapy given by non-specialist doctors, but not psychoeducation alone seem to reduce anxiety and facilitate a trend towards improved function in snakebite victims. However, these interventions had no effect on depression or PTSD.
