Quantifying psychological distress among cancer patients in interventions and scales: a systematic review.
The management of cancer-related psychological distress has been addressed in numerous studies, which have examined both the development of interventions to alleviate psychological distress as well as scales for evaluating their efficacy. In this systematic review, we examine results from randomized controlled trials (RCTs) on the relative effectiveness of interventions in reducing cancer-related psychological distress and the scales employed to measure this distress. An electronic database search for RCTs of psychological interventions in cancer patients from October 2008 to July 2013 was conducted using PubMed, MEDLINE, and CINAHL. Data was independently extracted and assessed by two researchers. Nineteen RCTs on interventions for psychological distress were identified and analyzed, among which eight studies reported that the interventions had a positive effect and improved the symptoms of psychological distress, and in which seven main instruments were used to measure psychological distress. The most frequently employed interventions were exercise training, cognitive behavioral therapy, and complementary therapy, followed by meeting with a psychologist and a combination of keeping a written journal and peer counseling. The three most frequently employed scales were the Profile of Mood States-Short Form (POMS-SF), Distress Thermometer (DT), and Hospital Anxiety and Depression (HADS). The majority of cancer patients experience considerable psychological and emotional distress at some time during the course of the disease. Reports have shown that interventions such as exercise training, cognitive behavioral therapy, and complementary therapy can assist oncology personnel in alleviating this distress. Future studies should consider optimizing such interventions. The POMS-SF scale, which has frequently been employed to measure the effects of psychological distress, could be incorporated into elements of screening programs for measuring unfulfilled needs, desire for assistance, clinical response, and longitudinal outcomes.
