The error occurs in the presentation of responses that invariably occur in written language format, rather than in a signed language, a contravention of international translation guidelines. The present study aims to modernise the field of Deafness and Mental Health using a web-based interface to improve the valid and reliable detection of SMI in signing Deaf people. In this study, the psychometric properties of an Australian Sign Language (Auslan) translation of both versions of the Kessler Psychological Scales of Distress (K10 and K6), were examined. The scales were translated according to World Health Organisation World Mental Health Survey protocols featuring graphics interchange format (GIF) technology as the response modality, then administered to 30 signing Deaf participants. Results of internal consistency showed that the K10-Auslan and K6-Auslan have acceptable reliability as measures of SMI in SYSTEMATIC ERROR 2 Australian Deaf people.
