Penn T, Overstreet D, Sims A, et al. - Among 129 individuals experiencing chronic low back pain (CLBP), it was investigated if the association between income status (i.e., an indicator of socioeconomic status) and physical function is mediated by perceived injustice. Researchers found that the link between income level and physical function was significantly mediated by perceived injustice, in a regression-based model adjusted for gender, racial/ethnic status, depression, and current level of pain severity. Particularly, greater perceived injustice in relation to lower level of income was revealed, which in turn was related to diminished physical performance. This work is among the first to assess links between socioeconomic status, perceived injustice, and physical function. According to findings, injustice perception may represent a mechanism whereby current physical function is influenced by income status, likely potentially resulting in long-term disability over time. These data strengthen the importance of further assessing injustice appraisals as targets for intervention, particularly in low income people experiencing CLBP.
