ABSTRACT

Objective To establish symptom check list 90 (SCL-90) norm for Chinese oilmen.Methods Based on multi-level stratified or cluster sampling technique,a total of 13 472 oilmen from China National Petroleum Corporation completed a sampling survey on measured data of SCL-90.Student's t test and one-way analysis of variance (ANOVA) were used to compare gender,age,education level and marriage status.Results All the reliability coefficients were ＞ 0.8 and P for validity test was ＜ 0.05.In comparison with SCL-90 norm of healthy Chinese adults in 1986,the interpersonal sensitive (1.5 ± 0.6)and paranoia (1.4 ± 0.6) of oilmen were lower (t≤-4.17,both P ＜ 0.05),although other 8 factors showed higher scores (t ≥ 2.4,all P ＜ 0.05).Oilmen also had lower scores for each item than Chinese army men (t ≤-2.62,all P ＜ 0.05).Total score (131.4 ± 47.7),interpersonal sensitive (1.4 ± 0.6),hostility (1.5 ± 0.6),paranoia (1.4 ± 0.6) and psychosis (1.3 ± 0.5) of females were lower than those of males (t≥2.53,all P ＜ 0.05).30-39 years group indicated the highest scores for each item (all P ＜0.05),while 17-29 years group got the lowest (all P ＜ 0.05).Meanwhile,the subjects whose education level was equate to or lower than high school or those got married were found to have the highest scores (all P ＜ 0.05).Conclusions Our data show better item differentiation,reliability and validity of SCL-90.SCL-90 norm may be used for mental health assessment of Chinese oilmen.
