  The development of instruments to assess substance use that are easy to use, valid and reliable across cultures is an important task. The present study investigates the reliability and validity of the Chinese language version of the SDS (SDS[Ch]) when used to measure severity of dependence among heroin users in Taiwan (n=522). Data were collected on demographic data, heroin use behaviours, and criminal convictions. Taiwanese heroin users recorded high SDS[Ch] scores and the results support the validity and reliability of the Chinese version of the SDS. A positive correlation was found between SDS[Ch] scores and DSM-IV criteria for heroin dependence. SDS[Ch] scores were positively related to heroin injection, frequency of heroin injection, spending on heroin, earlier age of onset of heroin use and more drug-related criminal convictions. The findings support the suggestion that the concept of dependence as assessed by the SDS has cross-cultural validity.
