7 results must be treated with caution in the absence of a control group, but the survivors treated with this approach nonetheless show sustained improvement on 12 month follow up. Figure 3.

This was clearly a chronic group of survivors, with clinically significant disorders, and the results showed clear improvement for the whole sample. This suggests that the approach deserves further investigation, especially since the therapy approach is relatively simple in application and could be easily learned by a wide variety of different types of health workers. We are not aware that any attempt to replicate or extend this work has taken place, but the Brief Therapeutic Interview has been used subsequently by the Amani Trust in its work with other survivor groups. 2.4 Problem-solving Therapy In line with its commitment to improving the management and treatment of clients with mental disorders, the Amani Trust also investigated approaches for the treatment of forms of mental disorder other than those due to trauma or OVT. This work was informed by the continuous observation that nurses seemed to prefer a more directive approach in working with clients with psychological disorders, and hence a study was carried out to investigate an approach based in problem-solving11. Furthermore, as noted above, many clients seemed to demonstrate impaired problem-solving, and this was an additional interest in this study. The approach was very similar to the Nursing Process, an approach with which nurses are very familiar, and which has been used internationally. The process has five stages, and the nurse guides the patients through each of these stages as is described below. Stage 1 - Problem Identification Stage 2 - Problem Exploration 11 See Amani Trust (2002),A Pilot Study on the Effectiveness of Problem Solving Therapy on Primary Care Patients with Psychological Problems, HARARE: AMANI TRUST.
