Psychological distress and cancer pain: Results from a controlled cross-sectional survey in China

We evaluated the pain associated with cancer and its impact on pain management, anxiety, and depression in Chinese patients using a controlled cross-sectional study. One hundred and twenty-six cancer outpatients were evaluated from January 2012 to June 2014; 64 reported pain and 62 did not. Patients with cancer eligible for this study were older than 18 years and able to effectively communicate with medical personnel. Patients were administered a questionnaire regarding their medical status. The information collected was used along with patient charts to complete a socio-demographic and clinical characteristic summary for each patient. Results showed that patients who reported pain had mean State-Trait Anxiety Inventory (STAI) scores of 46.38 for state anxiety and 44.64 for trait anxiety, as well as a mean BDI (Beck Depression Inventory) score of 19.17. The pain-free patient group had mean STAI scores of 40.73 for state anxiety and 42.87 for trait anxiety, and a mean BDI score of 15.35. In conclusion, patients who reported pain were more prone to anxiety and depression, with pain severity being a strong predictor of anxiety. Adequate pain assessment and adjustment proved necessary for pain management.
