This study was done for identifying the factors which affect psychologic symptoms of low back(LBP) patients. The study subjects were 43 work-related low back pain patients, 28 work-related non-low back pain patients and 47 general low back injury patients. The study material is SCL 90-R for checking psychologic symptoms and questionnaire for obtaining general information about the subjects. The data were analyzed by model of analysis of covariance adjusted by several variables such as gender, age, education and marital status and then compared the least square means of symptom score between groups. To identify the factors that affect psychologic symptom, duration of suspension, return to work and interaction factor of these two variables were analyzed by multivariate model and we calculated partial correlation coefficient of these variables. As a result, work-related LBP patients showed higher score of symptoms in somatization, depression and psychosis than work-related non-LBP and non-work-related LBP. Duration of suspension and return to work were significant explanatory variables for psychologic symptom score of work-related LBP. Then, we may conclude that the treatment and rehabilitation programe for work-related LBP should cover the strategy of early return to work.
Key words: occupational low back pain; psychometric symptom score; early return to work
