Brief summary (from the registry)
Opioids are frequently prescribed for chronic low back pain (CLBP). Psychiatric illness, such as high levels of depression and anxiety symptoms, is a common co-occurrence in chronic pain patients (and is termed comorbid negative affect \[NA\]). The purpose of the study is to determine whether CLBP patients with either a high vs. a low or moderate degree of NA have different pain relief responses to oral opioids.
