The primary objective of this research was to evaluate the
psychometric properties of a questionnaire designed to assess perceive injustice
associated with injury. METHODS: 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.
RESULTS: -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. RESULTS: -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. CONCLUSIONS: 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.
