The Multidimensional Symptom Index (MSI) is a 10-item parallel score frequency×interference patient-reported outcome for use in clinical pain research. This manuscript describes results related to measurement stability, discriminative accuracy when screening for major depressive disorder (MDD), and prognostic validity when predicting recovery trajectories after acute musculoskeletal (MSK) trauma. ⋯ The MSI holds promise as a tool for evaluating change, screening for MDD, and identifying those at high or low risk of poor recovery. The results favor sensitivity over specificity. The labile nature of the acute pain symptoms and a truncated distribution of Nonsomatic Symptoms scores in that group both require some caution in interpretation. The MSI appears to be a potentially useful tool for rapid pain phenotyping, evaluation, and quick screening purposes in clinical practice.

Sleep disturbance is associated with persistence and exacerbation of chronic pain. As this relationship seems to be bidirectional, factors underpinning sleep disturbance may prove important in multimodal rehabilitation approaches. The aim of this cross-sectional study was to examine the impact of psychological symptoms on subjective and objective sleep measures in patients with chronic musculoskeletal pain (CMP), as compared with pain-free controls. ⋯ The differences in subjective and objective sleep measures indicate that they probe different aspects of sleep functioning in patients with musculoskeletal pain, and their combined application may be valuable in clinical practice. Self-reported sleep disturbance seems to overlap with affective dimensions reflected by the HSCL questionnaire.

There has been growing interest in examining pain-related activity patterns and their relationships to psychosocial functioning. The Patterns of Activity Measure-Pain (POAM-P) is frequently used to measure 3 pain-related activity patterns: avoidance, overdoing, and pacing. Although the POAM-P possesses excellent psychometric properties, its length may limit its utility where multiple measures of functioning are required or the time available for assessment is limited. The present studies describe the development and evaluation of a short-form version of this measure. ⋯ The short-form of the POAM-P possesses good psychometric properties and correlates well with the long-form of the measure. It appears to be a promising addition to existing measures of pain-related activity. It may be useful as an addition to questionnaire batteries that comprehensively assess the psychosocial functioning of individuals with ongoing pain.

Chronic low back pain (cLBP) is the leading cause of disability, with a significant societal cost. It disproportionately affects non-Hispanic blacks and individuals of lower socioeconomic status. The biopsychosocial framework has been used to study and manage cLBP, yet disparities persist. ⋯ Higher perceived social status is associated with less severe depressive symptoms, which in turn is associated with less pain severity and less pain interference for whites but not for blacks with cLBP.

The purpose of this study was to determine the association between presence of chronic pain and school functioning among school-aged children (6 to 17 y) using the most recent United States national data. ⋯ This study extends evidence linking chronic pain status to poorer school functioning in a large, national sample. Poor school functioning is a pressing public concern affecting children with chronic pain. Health care providers, educators, policymakers, and families should work together to ensure that needs are met for this vulnerable population.
