Results showed that the final model consisted
of both main effects and interaction terms between risk factor categories and had an adjusted R2 value of
0.85, a significant improvement over models developed for the individual categories
These findings
illustrate the need to consider all three broad categories of risk factors simultaneously in predicting
injury status and in developing effective potential intervention efforts.
Relevance to industry: Personal and psychosocial factors and interactions, in addition to occupational
factors, may be needed to be taken into account when designing future prevention strategies for persons
in jobs with high risks for low back pain. The factors identified here may also be used to develop
a predictive model for pain severity in workers.
