Abstract:
Objective:To develop the Adolescent Mental Health Computerized Adaptive Test(AMH-CAT)for assessing psychological crises in adolescents using item response theory(IRT).Methods:A total of 8 679 students,aged 9 to 19 years,were sampled from 14 primary and secondary schools.The item bank was constructed by examining unidimensionality,independence,discrimination,and Differential Item Functioning(DIF).The AMH-CAT algorithm was developed using R software and validated for reliability and validity through real and simulated data.The School Psychological Interview Evaluation Form served as the criterion tool to assess the predictive validi-ty of AMH-CAT in evaluating psychological crises levels.Results:The item bank,consisting of 43 items,demon-strated unidimensionality and independence,with discrimination values＞0.80 and no DIF across genders.Under va-rious stopping rules,AMH-CAT showed ABS values＜0.40,RMSE values＜0.50,and a correlation(r)＞0.87(P＜0.001)between estimated and true psychological crises levels.Real participants answered an average of 10 items under the SE(θ)≤0.4 stopping rule,with a reliability of 0.89,and the scores were positively correlated with the complete item bank scores(r=0.95,P＜0.001).The predictive accuracy for Level 1 and Level 2 concerns was 0.89 and 0.90,respectively.Conclusion:The Adolescent Mental Health Computerized Adaptive Test(AMH-CAT)demonstrates excellent validity,reliability and assessment efficiency for evaluating adolescent psychological crises.
