A correlational design was used to assess the convergent and discriminant validity of the Dental Anxiety Inventory (DAI), a newly developed measurement instrument designed to circumvent shortcomings of other dental anxiety questionnaires. Convergent validity was supported by a high correlation between the DAI and Corah's Dental Anxiety Scale. Discriminant validity was supported by small positive correlations with scales for neuroticism, anxiety, and fear, and nonsignificant correlations with other variables such as extroversion. The results support the construct validity of the DAI.
采用相关设计来评估牙科焦虑量表（DAI）的聚合效度和区分效度，该量表是一种新开发的测量工具，旨在克服其他牙科焦虑问卷的缺点。DAI与科拉牙科焦虑量表之间的高度相关性支持了聚合效度。与神经质、焦虑和恐惧量表的小正相关以及与外向性等其他变量的非显著相关性支持了区分效度。结果支持了DAI的结构效度。
