“I matter too!” – The effect of the drama therapy self-image module on clients with a personality disorder and low self-esteem: an experimental multiple baseline single case study

Background: Low self-esteem is a major problem in people with a personality disorder. This study examined the effect of the protocolised drama therapy self-image module (DSIM) on the self-esteem and well-being of these clients. We also investigated how participants experienced the module. Method: Within a multiple baseline single case experimental design, eleven participants (n=11) with a personality disorder and low self-esteem were scored weekly on the Rosenberg Self Esteem Scale and the Mental Health Continuum-Short Form before, during and following participation in the module. The module consisted of six weekly 75-minute group sessions. Eight participants (n=8) were interviewed about their experiences with the module. Results: Self-esteem and well-being increased during and following participation in the module. A significant improvement could also be seen at group level. The interviews showed that participants appreciated the module, although they perceived it as too short. Conclusion: The results suggest that the module is likely to contribute to increases in self-esteem and well-being in clients with a personality disorder. These results seem to justify adding the module to the standard therapy programme for these clients. The results are tentative because the effect of the module was not compared with that of a control intervention. Future research may shed more light on this.
