In addition to the instrument’s psychometric properties, several additional factors may have contributed to the high levels of reliability observed in the current study. Although the SSADDA was developed for use by interviewers without formal clinical training and has been shown to be reliable when administered by this group, our study used a highly skilled team of trained psychiatric nurses with considerable prior experience in the evaluation and treatment of clinical populations (including members of the specific ethnic group under study). Therefore, reliability may be lower in a less skilled set of interviewers, particularly those without experience interacting with Hmong individuals. As such, future evaluation of the Thai instrument’s reliability in non-clinically trained research personnel and in other ethnic groups in Thailand is warranted.
