This article represents a psychologist's perspective on the case study of Doris, a middle-aged woman with metastatic breast cancer who is initially referred to Chaplain Rhonda for assistance with death anxiety. In the field of psychology, it has long been accepted that good clinical research is informed by theory. As such, Chaplain Rhonda's intervention with Doris will be examined through the lens of object relations theory. Specifically, we will see how Rhonda's relationship and interaction with Doris improves her image of God and, by doing so, decreases her death anxiety. In psychological research, it is also important to accurately measure the effects or outcomes of clinical interventions. In this light, several suggestions are offered for the measurement of constructs relevant to the case of Doris, namely God image and death anxiety. Finally, a simple case study research design, applying the aforementioned theory and measurement, is provided as a suggested starting point for research on the efficacy of chaplaincy interventions.
