Work perceptions and psychosocial factors affecting the report of back injury were examined. A longitudinal prospective study was conducted on 3,020 aircraft employees to identify risk factors for reporting acute back pain at work. During slightly more than four years of followup, 279 subjects reported back problems. Other than a history of current or recent back problems, the factors noted to be most predictive of subsequent reports in a multivariate model were work perceptions and certain psychosocial responses. Subjects who stated that they hardly ever enjoyed their job tasks were 2.5 times more likely to report a back injury than subjects who almost always enjoyed their job tasks. The quintile of subjects scoring highest on Scale-3 of the Minnesota Multiphasic Personality Inventory were two times more likely to report a back injury than subjects with the lowest scores. The multivariate model revealed that subjects in the highest risk group had 3.3 times the number of reports in the lowest risk group. The authors conclude that the results emphasize the importance of adopting a broader approach to the multifaceted problem of back complaints in industry. The results help to explain why past efforts focusing purely on physical factors have been unsuccessful.
