中文摘要 | 本研究旨在利用試題反應理論混合模式(IRT Mixture Model),探討國中生家庭與學校生活適應因素結構,並藉由潛在異質性分析,進一步瞭解家庭關係與學校生活適應困擾之潛在次群體。研究樣本為中部某市立國民中學全校一至三年級各18班共1703位學生。結果發現,二類別二因子IRT Mixture測量恆定模式在一系列競爭模型中,展現出最佳模式適配。其中,二因子代表學校學習與家庭適應困擾,二類別反應高家庭困擾與低家庭困擾,二族群的學習困擾分數無顯著差異。比對試題區辨度發現,IRT Mixture與IRT估計維持一致。與潛在類別分析(LCA)分類結果交叉分析發現,IRT Mixture分類著重於家庭困擾程度。文末並針對本研究結果在輔導與諮商實務意涵以及應用IRT Mixture於實徵研究資料所面臨之挑戰,做出具體討論與建議。 |
英文摘要 | The study utilized IRT Mixture Model to investigate latent heterogeneity of school learning and family relationships to differentiate latent classes and disturbance severity of middle school students. Four statistical models were examined, including IRT, LCA, IRT Mixture (parameters constrained) and IRT Mixture (parameters non-constrained). Results show that two-class two-factor IRT mixture model with constrained parameters provides the best fit of our data. Two factors are school learning and family relationship, and the two classes are high-risk and normal groups. Estimations of IRT Mixture Model are comparable to those of IRT and LCA. In conclusion, mixture models demonstrate more modeling flexibility compared to those of traditional statistical models, but they require larger sample size, longer computer running hours, and more difficulties in reaching algorithm convergence. |
