Multicenter Study Observational Study
Pain assessment for chronic lower back pain: performance of the PAL-S and PAL-I patient-reported measures for symptoms and impacts.
Objective: The Patient Assessment for Low Back Pain-Symptoms (PAL-S) and the Patient Assessment for Low Back Pain-Impacts (PAL-I) were developed to incorporate patient perspective of treatment benefit in chronic low back pain (cLBP) trials. This study documents psychometric measurement properties of the PAL-S and PAL-I. Methods: In this multicenter, observational study, eligible participants clinically diagnosed with cLBP provided sociodemographic information and completed PAL measures and other patient-reported outcome measures of pain and/or disability. ⋯ Both measures significantly differentiated between pain intensity levels (based on numeric response scale) and painDETECT groups. Conclusion: The PAL-S and PAL-I generated highly reliable scores with substantial evidence of construct validity. Routine use of these measures in treatment trials will enhance comparability of LBP-related symptom and impact results, including patient perspective of treatment benefit.

Pediatric pain assessment in the hospital traditionally involves the patient's self-report of pain intensity using a numeric rating scale, which does not capture the complexity of the pain experience. No valid, comprehensive measure of pain in hospitalized youth exists. This study was designed to develop and conduct initial psychometric testing of the Pediatric American Pain Society Patient Outcomes Questionnaire (Pediatric APS-POQ), a comprehensive patient-reported measure of pain and pain outcomes in hospitalized youth. ⋯ Additional research is needed to further support the reliability and validity of this measure in diverse clinical populations. PERSPECTIVE: To reduce the impact of pain on hospitalized youth, pediatric pain assessment must move beyond ratings of pain intensity. The Pediatric APS-POQ provides a brief but comprehensive assessment of pain and pain outcomes in hospitalized children and adolescents, which will allow for greater individualization in hospital-based pain management and quality improvement purposes.

The Critical-Care Pain Observation Tool (CPOT) is recommended for evaluating pain behaviors in patients in the intensive care unit who are unable to report pain. The source of the only published Spanish version of the CPOT does not verify that it underwent a formal translation process. ⋯ The Spanish version is ready to undergo validation with patients in the intensive care unit, which is the next step toward its use in assessing pain behaviors among patients in intensive care units where Spanish is spoken.

Pediatric chronic pain evaluation includes self-reports and/or caregiver proxy-reports across biopsychosocial domains. Limited data exist on the effects of caregiver-child discrepancies in pediatric pain assessment. In children with chronic pain, we examined associations among discrepancies in caregiver-child reports of child anxiety and depressive symptoms and child functional impairment. ⋯ Discrepant caregiver-child perceptions of child anxiety and depressive symptoms may be associated with functioning in children with chronic pain, especially when caregivers report less child internalizing symptoms. These findings highlight the need for further examination of the effects of caregiver-child discrepancies on pediatric chronic pain outcomes and may indicate targets for intervention.

Background and aims Conditioned Pain Modulation (CPM) is a measure of pain inhibition-facilitation in humans that may elucidate pain mechanisms and potentially serve as a diagnostic test. In laboratory settings, the difference between two pain measures [painful test stimulus (TS) without and with the conditioning stimulus (CS) application] reflects the CPM magnitude. Before the CPM test can be used as a diagnostic tool, its reliability on the same day (intra-session) and across multiple days (inter-session) needs to be known. ⋯ The CPM test was more reliable in women than in men, and in older vs. younger participants. Discussion The CPM test was most reliable when the TS was applied to the dominant hand and CS performed on the contralateral hand. These data indicate that using the CS and TS in the same but contralateral dermatome in CPM testing may create the most reliable results.
