          Abstract

          ABSTRACT BACKGROUND AND OBJECTIVES: To date, there is no information on the perception of injustice in patients with musculoskeletal pain in Brazil. The present study evaluated the perception of injustice in individuals with chronic musculoskeletal pain and its association with pain intensity. METHODS: Information regarding the participants’ identification and experience of injustice was gathered using the Injustice Experience Questionnaire. Pain intensity data was collected through the numerical pain rating scale. The descriptive data analysis was performed. Pearson’s correlation test was used to verify the association between pain intensity and perceived injustice. The level of significance adopted was alpha=95%. RESULTS: The study was composed of 110 patients with chronic musculoskeletal pain being 94 women with a mean age of 62.9±14.9 years. The mean perceived injustice was 19.45±11.68 out of a total of 48 points. The mean pain intensity was 6.39±2.48. The correlation between pain intensity and perceived injustice was r=0.23 [CI (95%) = 0.04 to 0.40; p=0.008]. The correlation between blame and unfairness and pain intensity was r=0.16 (p=0.08). For the severity and irreparability domain the correlation was r=0.28 (p=0.003). CONCLUSION: Patients with chronic musculoskeletal pain presented low levels of perceived injustice. The total score and the severity and irreparability domain of the perceived injustice instrument showed a weak correlation with pain intensity.

          RESUMO JUSTIFICATIVA E OBJETIVOS: Até o presente momento, não existem dados sobre a percepção de injustiça em pessoas com dor musculoesquelética no Brasil. O presente estudo avaliou a percepção de injustiça em pessoas com dor musculoesquelética crônica e a sua associação com a intensidade de dor. MÉTODOS: Foram coletadas informações referentes à identificação e experiência de injustiça utilizando o Questionário de Injustiça Percebida e a intensidade da dor utilizando a escala numérica da dor. Foi realizada a análise descritiva dos dados. O teste de correlação de Pearson foi utilizado para se verificar a correlação entre a intensidade de dor e a injustiça percebida. O nível de significância adotado foi de alfa=95%. RESULTADOS: Foram incluídos 110 pacientes com dor musculoesquelética crônica, sendo 94 mulheres com média de idade de 62,9±14,9 anos. A média da injustiça percebida foi de 19,45±11,68 de um total de 48 pontos. A intensidade média de dor foi 6,39±2,48. A correlação entre a intensidade de dor e a injustiça percebida foi de r=0,23 [IC (95%) = 0,04 a 0,40; p=0,008]. A correlação entre culpa e injustiça e a intensidade de dor foi de r=0,16 (p=0,08). Para o domínio gravidade e irreparabilidade foi de r=0,28 (p=0,003). CONCLUSÃO: Os pacientes com dor musculoesquelética crônica apresentam baixos níveis de injustiça percebida. A pontuação total e o domínio de gravidade e irreparabilidade do instrumento de injustiça percebida apresentaram correlação fraca com a intensidade de dor.

          The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement: guidelines for reporting observational studies.

          Much biomedical research is observational. The reporting of such research is often inadequate, which hampers the assessment of its strengths and weaknesses and of a study's generalisability. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Initiative developed recommendations on what should be included in an accurate and complete report of an observational study. We defined the scope of the recommendations to cover three main study designs: cohort, case-control, and cross-sectional studies. We convened a 2-day workshop in September 2004, with methodologists, researchers, and journal editors to draft a checklist of items. This list was subsequently revised during several meetings of the coordinating group and in e-mail discussions with the larger group of STROBE contributors, taking into account empirical evidence and methodological considerations. The workshop and the subsequent iterative process of consultation and revision resulted in a checklist of 22 items (the STROBE Statement) that relate to the title, abstract, introduction, methods, results, and discussion sections of articles. 18 items are common to all three study designs and four are specific for cohort, case-control, or cross-sectional studies. A detailed Explanation and Elaboration document is published separately and is freely available on the Web sites of PLoS Medicine, Annals of Internal Medicine, and Epidemiology. We hope that the STROBE Statement will contribute to improving the quality of reporting of observational studies.

            Disrespect and the experience of injustice.

            D T Miller (2001)
            This review analyzes research and theory pertaining to the psychology of injustice, using as its organizing theme the role that the perception of disrespect plays in the experience of injustice. The analysis focuses primarily on the links between disrespect and anger, disrespect and injustice, and anger and injustice. Determinants of the intensity of people's reactions to injustices are also reviewed. In addition, the review examines the goals of retaliation as well as the forms that retaliation can take. Parallels between justice reactions to those acts of disrespect directed toward the self and those directed toward others are noted. Finally, the review discusses the implications of justice research for understanding the specific and general entitlements that people believe are their due.

              The role of perceived injustice in the experience of chronic pain and disability: scale development and validation.

              The primary objective of this research was to evaluate the psychometric properties of a questionnaire designed to assess perceive injustice associated with injury. In Study 1, the 12-item Injustice Experience Questionnaire (IEQ) was administered to 226 individuals with musculoskeletal conditions. A subsample of 85 individuals were interviewed 1-year later about their ongoing symptoms and return to work status. In Study 2, the IEQ and other pain-related measures were administered on two separate occasions to 70 pain patients participating in a functional restoration rehabilitation program. -Study 1 Principal components analysis yielded a two-component solution with eigenvalues greater 1. Item content of the two components reflected elements of blame and irreparability of loss. In cross sectional analyses, the IEQ was significantly correlated with measures of catastrophic thinking, r = .75, P < .01, fear of movement/re-injury, r = .58, P < .01, depression, r = .66, P < .01, and pain severity, r = .54, P < .01. Cross-sectional regression analyses revealed that the IEQ, beta = .44, P < .01, and the PCS, beta = .18, P < .05, each contributed significant unique variance to the prediction of pain severity. The IEQ prospectively predicted return to work status, OR = .75, 95% CI = .58-.99, but not pain severity. -Study 2 Analyses supported the test re-test reliability of the IEQ, r = .90, P < .01. Treatment-related changes in the IEQ were significantly correlated with an objective index of improved physical function, r = .51, P < .01. The findings of these two studies support the construct validity of the IEQ and suggest that this measure might be a useful complement to psychosocial assessment of individuals with persistent pain conditions. Discussion addresses the processes through which perceived injustice might impact on disability and rehabilitation outcomes.
