title: Predictive validity of the Chinese version of the Adult Suicidal Ideation Questionnaire: psychometric properties and its short version.
abstract: The success of screening for individuals at suicidal risk among the general population relies heavily on the availability of a reliable and validated instrument. However, there remains a lack of a well-validated screening tool for suicidal risk in Chinese, despite the fact that about a quarter of the world's suicides takes place in China. In view of the severity of the suicide problem among the Chinese population, there is a crucial need to develop robust screening tools locally. This study investigates the psychometric properties related to the Chinese version of the Adult Suicidal Ideation Questionnaire (ASIQ) with a 2-wave, population-based panel study in the Hong Kong Special Administrative Region, People's Republic of China. Two-thousand sixteen Chinese people were interviewed for their suicidality, psychological well-being, and ASIQ scores. The Chinese ASIQ was shown to have strong internal reliability, convergent validity, and factorial validity. This study also demonstrated its predictive validity by examining sensitivity and specificity in identifying subsequent suicidality. A 4-item short version of ASIQ was also developed.
