Cross-cultural adaptation of the Spence children's anxiety scale in Malaysia.

INTRODUCTION Anxiety among children has increased in recent years. Culturally adapted questionnaires developed to measure the level of anxiety are the best screening instruments for the general population. This study describes the scientific translation and adaptation of the Spence Children's Anxiety Scale (SCAS) into the Malay language. METHOD The process of scientific translation of this selfreport instrument followed the guidelines of the Task Force for Translation and Cultural Adaptation of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). RESULTS The Malay version and its adaptation for a new cultural context are described. CONCLUSION The Malay version achieved the aims of the original version and its conceptual and operational equivalence. It may be used as the first Malay instrument to measure anxiety among children in research and in clinical and community settings.
