Objectives: The aim of the present study was to assess the reliability and validity of the Persian version of the State-Trait Anxiety Inventory Form Y (STAI-Y) among high school students.
Methods: A sample of 492 high school students in Kermanshah city, Iran were randomly selected via multistage sampling. They were asked to complete the STAI-Y and Beck Anxiety Inventory (BAI) to determine the correlation coefficients. Data analysis was performed via descriptive statistics, factor analysis, Cronbach's coefficient alpha, and Pearson correlation coefficient.
Results: In the Persian version of STAI-Y, the Cronbach's alpha for internal consistency was 0.886 for trait anxiety and 0.846 for state anxiety. The convergent validity between STAI-Y and BAI was 0.612 for trait anxiety and 0.643 for state anxiety (p < 0.001).
Conclusion: The reliability, internal consistency, and validity of the Persian version of the STAI-Y is good among high school students in Kermanshah.
