Abstract
Background Chronic pain can lead to economic instability, decreased job productivity, and poor mental health. Therefore, reliable identification and quantification of chronic pain is important for clinical diagnosis and treatment. Objective To determine the psychometric properties of the Spanish language versions of the Pain Interference Index (PII) and the Short Form McGill Pain Questionnaire (SF-MPG) among a population of working adults who experienced injury in Santiago, Chile. Methods A total of 1,975 participants with work-related injuries were interviewed to collect sociodemographic, occupational, and chronic pain characteristics. Construct validity and factorial structure of the PII and SF-MPG were assessed through exploratory factor analyses (EFA). Cronbach’s alpha was used to evaluate internal consistency. Results The PII mean score was 3.84 ± 1.43 among all participants. The SF-MPG median score was 11 [IQR: 6–16] in this study population. Cronbach’s alpha for the PII was 0.90 and 0.87 for the SF-MP. EFA resulted in a one factor solution for the PII. A two-factor solution was found for the SF-MPG. The two-factors for SF-MPG were sensory and affective subscales with Cronbach’s alpha of 0.82 and 0.714, respectively. When the two scales were combined, an EFA analysis confirmed the PII and SF-MPG measure different aspects of chronic pain. Conclusions The PII and SF-MPG had good construct validity and reliability for assessing different aspects of chronic pain among working Chilean adults.

THE JOURNAL OF PAIN 2021; 22:1578-1585. [PMID: 34214701 DOI: 10.1016/j.jpain.2021.06.008] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/01/2021] [Revised: 06/08/2021] [Accepted: 06/17/2021] [Indexed: 12/30/2022]
Abstract
Racial equity is imperative to the future and integrity of scientific inquiry. In 2020, citizens of the United States (and globally) witnessed one of the most vile and egregious experiences of police brutality and systemic racism in recent history, the public execution of a Black American man. While some may isolate this and other similar events from influencing the scientific endeavors of pain researchers, events such as this can have a direct impact on the study, lived experience, and expression of pain in Black Americans. To truly understand the biopsychosocial effects of inequality and injustice on pain disparities, we must consider the unintended consequences that our current research approaches have in limiting the reliability and validity of scientific discovery. As we reflect on our current research practices in an effort to improve pain science, this perspective article discusses ways to initiate positive change in order to advance the science of pain in more equitable ways, not just for Black Americans, but for all individuals that identify as part of an underrepresented group. PERSPECTIVE: Elimination of inequities in pain care and research requires the identification, naming, and mitigation of systemic discriminatory and biased practices that limit our understanding of pain disparities. Now is the time to divest from traditional research methods and invest in equitable and innovative approaches to support pain researchers in advancing the science and improving the lives of people with pain.
