Tree of Life Zimbabwe measures mental health symptoms using the World Health Organization (WHO) SRQ-20. As outlined earlier, the SRQ-20 is a mental health screening instrument developed by WHO, that has been used in many countries of the world including Guinea Bissau, Sudan, Ethiopia, Kenya, and South Africa, and which has also been widely used in Zimbabwe, including with torture survivors.
We selected the SRQ-20 because it screens for a broader range of psychological disorders than measures focusing exclusively on post-traumatic stress disorder (PTSD) and depression. SRQ scores of 7 and above (>6) indicate that clients are in need of clinical support, while scores of 10 and above (>9) are considered to be severe cases.
The data analysis below shares the before and after results of our SRQ-20 assessments.
Graph 1: Average SRQ-20 scores at intake and at follow-up, 2013 – 2016
The graph below shows that on average, clients coming into the trauma healing workshops scored a very high 10 or 11 at intake (severe cases needing clinical support). However, upon the 3-month post workshop follow-up, most clients scored a very healthy average of 3 or 4.
Table 1: Comparison of pre and post clinical cases: 2013 – 2015
The table below compares the average SRQ-20 scores at intake and at follow-up as well as the clinical and severe cases before and after trauma healing workshops, from 2013 to mid 2016. Initially a very high percentage of clients were either severe or clinical cases, in need of psychological support. However, at follow-up, a much lower percentage of people remained clinical or severe, with most participants recording low SRQ-20 totals, well below cut-off points.
