Translation of the Broad Autism Phenotype Questionnaire to an Indian language: A description of the process

• Broad Autism Phenotype Questionnaire (BAPQ) assesses the Broad Autism Phenotype.
• BAPQ has three domains; aloof personality, pragmatic language, rigid personality.
• We enumerate the robust process adopted for the translation of the BAPQ.
• We recommend the use of ISPOR and WHO guidelines for translation.

The Broad Autism Phenotype Questionnaire (BAPQ) which is a reliable, efficient and easy to administer instrument is used to assess the Broad Autism Phenotype (BAP). In order to understand cross cultural perspectives using this instrument, a key process is translation of the instrument. The process of translation is often overlooked and hence the quality of the translated instrument may suffer. This paper highlights the robust process adopted for translating the BAPQ into one of the Indian languages – Kannada, using the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) and World Health Organisation (WHO) guidelines. The translated instrument was tested on a pilot sample of parents of 10 children with ASD and parents of 11 typically developing children. The results are in congruence with the published literature.
