有興趣的3個IRT主題之論文選讀(11.11更新)

1. develop staging or classification:

McTaggart-Cowan, Helen M, Brazier, John E, & Tsuchiya, Aki. (2010). Clustering Rasch results: A novel method for developing rheumatoid arthritis states for use in valuation studies. Value in Health, 13(6), 787-795.

Okochi, J., Takahashi, T., Takamuku, K., & Escorpizo, R. (2013). Staging of mobility, transfer and walking functions of elderly persons based on the codes of the International Classification of Functioning, Disability and Health. BMC Geriatr, 13, 16. doi: 10.1186/1471-2318-13-16

Woodbury, M. L., Velozo, C. A., Richards, L. G., & Duncan, P. W. (2013). Rasch analysis staging methodology to classify upper extremity movement impairment after stroke. Arch Phys Med Rehabil, 94(8), 1527-1533. doi: 10.1016/j.apmr.2013.03.007

這個主題是自己目前最有興趣的，我希望未來有機會可以使用Rasch/IRT將個案分類，如：用

Motor/Balance/ADL...能力描述個案的recovery state，呈現的方式不是只有一個指標分數，而

是一一呈現個案這些能力的狀況，然後呈現recovery state的等級。

2. link/compare outcomes: 

Edelen, M. O., & Saliba, D. (2010). Correspondence of verbal descriptor and numeric rating scales for pain intensity: an item response theory calibration. J Gerontol A Biol Sci Med Sci, 65(7), 778-785. doi: 10.1093/gerona/glp215 

Fischer, H. F., Tritt, K., Klapp, B. F., & Fliege, H. (2011). How to compare scores from different depression scales: equating the Patient Health Questionnaire (PHQ) and the ICD-10-Symptom Rating (ISR) using Item Response Theory. Int J Methods Psychiatr Res, 20(4), 203-214. doi: 10.1002/mpr.350 

Haley, S. M., Ni, P., Lai, J. S., Tian, F., Coster, W. J., Jette, A. M., . . . Cella, D. (2011). Linking the activity measure for post acute care and the quality of life outcomes in neurological disorders. Arch Phys Med Rehabil, 92(10 Suppl), S37-43. doi: 10.1016/j.apmr.2011.01.026

之前對IRT特別有興趣是因為IRT能夠比較測同一個特質/能力之不同量表的結果，我覺得這樣

可以相互解讀的評估結果才具有意義，所以這個類別也是自己想要去深刻了解的。

3. improve reliability/precision/discrimination:

Forero, C. G., Vilagut, G., Adroher, N. D., & Alonso, J. (2013). Multidimensional item response theory models yielded good fit and reliable scores for the Short Form-12 questionnaire. J Clin Epidemiol, 66(7), 790-801. doi: 10.1016/j.jclinepi.2013.02.007

Shih, C. L., Chen, C. H., Sheu, C. F., Lang, H. C., & Hsieh, C. L. (2013). Validating and improving the reliability of the EORTC qlq-c30 using a multidimensional rasch model. Value Health, 16(5), 848-854. doi: 10.1016/j.jval.2013.05.004 

van den Berg, S. M., Paap, M. C., Derks, E. M., Genetic, Risk, & Outcome of Psychosis, investigators. (2013). Using multidimensional modeling to combine self-report symptoms with clinical judgment of schizotypy. Psychiatry Research, 206(1), 75-80. doi: http://dx.doi.org/10.1016/j.psychres.2012.09.015

因想更了解以multidimensional IRT model增加reliability的概念及作法，故選擇此主題。
