Purpose/Objectives:
To determine the degree to which nurses recognize levels of depressive symptoms in their patients with cancer and to describe patient characteristics that influence the accuracy of nurses' perceptions of depressive symptoms.
Design:
Descriptive, prospective correlational design.
Setting:
25 community-based ambulatory oncology clinics affiliated with Community Cancer Care of Indiana.
Sample:
40 clinic nurses rated the depression levels of 1,109 patients.
Methods:
Patients completed the Zung Self-Rating Depression Scale (ZSDS) prior to their medical oncology clinic appointment. Nurses rated their patients' level of depressive symptoms, anxiety, and pain on a 0-10 numerical scale along with determining a performance status score.
Main Research Variables:
Patient-rated depression and the nurse depression rating.
Findings:
The most frequent agreement between nurses and patients was observed when patients reported little or no depressive symptoms. They were only concordant 29% and 14% of the time in the mild and moderate/severe ranges, respectively. Nurses' ratings were influenced most by patients' endorsement of frequent and obvious mood symptoms and nurse ratings of patients' anxiety and pain.
Conclusions:
A marked tendency existed to underestimate the level of depressive symptoms in patients who were more severely depressed. Nurses' ratings were most influenced by symptoms such as crying, depressed mood, and medical factors that are useful but perhaps not the most reliable indicators of depression in this population.
Implications For Nursing Practice:
Nurse assessment of depression might be improved if greater emphasis were placed on the more diagnostically reliable symptoms of depression and if screening tools for depression were incorporated into nursing practice.
