[Normalizing SCL-90-R inventory in guilan high-school students]

ABSTRACT

SCL-90-R inventory is used for screening and assessing effect of some treatment. Its sensitivity depended on environmental factors; there are many shortcomings of its normalization in our community. To normalize SCL-90-R inventory in Guilan high-school students in the years of 2003-2004. In a cross-sectional study, 4015 subjects were selected of 153948 students using multistage cluster sampling. New version of Persian SCL-90 R, that its content validity and reliability were examined and proved [r=0.86] was used. We determined validity and reliability of new version and prepared normal tables. Data was processed with SPSS 11.5 and analyzed by appropriate statistical tests [alpha=0.05]. There were 2005 females and 2010 males that 1242 subjects were in 3rd grade and 1341 subjects were in 17 years age group. The most reliability coefficient found for depression; with test retest [r=0.93], splitting [r=0.85]; and Crunbach alpha [r=0.85]. There was a correlation between all 9 factors and with three global indices [r>0.50] and between 9 dimension of SCL-90-R and MMPI scales, that most correlation were between depression and anxiety [SCL-90-R] with neurasthenia in MMPI [r=0.59]; and compulsive-obsessive, psychosis with schizophrenia [r=0.58] we found a statistical correlation between two tests [alpha=0.05]. There was most mean and standard deviation [1.58 and 0.76 respectively] in females and in males [1.41 and 0.71 respectively] for paranoid scales. We found GSI mean and standard deviation 1.16 and 0.59 in females and 0.92 and 0.49 in males respectively with statistically significant difference [alpha= 0.05]. Our new Persian version of SCL-90-R inventory has acceptable validity and reliability and can be used as measurement a general psychological symptoms in Guilan students
