AI Article Synopsis

  • This study examined the norms for the Symptom Checklist 90 (SCL-90) in China, involving 7,489 adults from Tianjin and Qingdao and comparing their data with existing norms from other studies.
  • Significant changes were found in SCL-90 factors over time, with compulsion scoring highest and phobia lowest; overall scores showed an increasing trend annually.
  • The study suggests that the current critical screening values for the SCL-90 are outdated and recommends developing new norms, proposing the mean plus one standard deviation as a more appropriate standard.

Article Abstract

This study aimed to investigate the Chinese norms for the Symptom Checklist 90 (SCL-90) scale and its application. In total, 7,489 adults from Tianjin and Qingdao in China were included. Their data were compared with the norm data of 1,388 people published by Jin et al., the combined norms published by Tang et al., the data of 2,808 adults published by Chen and Li, and the data of 1,890 adults from Tong in China. In five different periods, notable changes were observed in each factor of the SCL-90 that significantly differed from the previous norms. The scores of each factor showed an increasing annual trend. Compulsion consistently obtained the highest scores, and phobia consistently obtained the lowest scores. The scores tended to decrease from compulsion to anxiety, and psychosis scored lower than paranoia. There was a significant difference in the detection rate between the critical screening value of two points and the standard score. Using the standard score as the critical value, the detection rate ranged between 13 and 16% and was relatively concentrated. Using two points as the critical value, the detection rate ranged between 38 and 50%. The usual model in China is not consistent with social development. Using two points as the critical value is no longer suitable for the SCL-90. New Chinese norms and measurement standards should be developed. The mean value plus one standard deviation could be used as the new measurement standard.
