Exploring the prevalence and construct validity of high-impact chronic pain across chronic low-back pain study samples.

ABSTRACT: BACKGROUND CONTEXT:The US National Pain Strategy focused attention on high-impact chronic pain and its restrictions. Although many interventions have been studied for chronic low-back pain, results are typically reported for heterogeneous samples. To better understand chronic pain and target interventions to those who most need care, more granular classifications recognizing chronic pain's impact are needed. PURPOSE:To test whether chronic pain impact levels can be identified in chronic low-back pain clinical trial samples, examine the baseline patient mix across studies, and evaluate the construct validity of high-impact chronic pain. STUDY DESIGN/SETTING:Descriptive analyses using 12 large study datasets. PATIENT SAMPLES:Chronic low-back pain patients in nonsurgical, nonpharmacologic tri
