| Grade Response Model and Rating scale model is aimed at a polytomous scoring item of modern test theory, play a huge advantage in psychometrics.This research on the study of parent-child relationship data based on the review analysis, compiled the scale about adolescent parent-child relationship intimacy. The data were analysed using GRM and RSM measurement techniques, and briefly analyzes the features of the adolescent parent-child relationship intimacy in guiyang.Shows GRM and RSM on scaling and revised the specific application and model selection.Result display:(1) Adolescent parent-child relationship intimacy scale into the separate subscales of father subscales and mother subscales, both confirmed the unidimensionality. According to the discrimination GRM, the discrimination and threshold all conform to the standard. According to project the difficulty, discrimination, such as item parameters, comprehensive item characteristic curve of questionnaire revised, the final mother subscales remaining 14 items, the final father subscale remaining 15 questions, both had good reliabilities and validities.(2) Rating scale model shows that, after the delete questions, the mother subscales and the father subscales of Infit MNSQ range value and Outfit MNSQ range values are within the acceptable range. Item thresholds are concentrated, did not cover all students’ ability levels. Separating and Reliability are good. The interval of thresholds among category 1, 2 3 are slightly smaller. The category probability curve 2, almost be covered, means the settings of category is bad. Will project 2 and 3 after the merger, the thresholds spacing have improved, but reduce the amount of test information, the model-data fit situation become worse. It is recommended to use questionnaire, change the score level.(3) In this study, rating scale model can provide more help for scaling.(4) Adolescent parent-child relationship intimacy in secondary level or above, have the polarization. In grade differences, whether it is a intimacy status with the father or mother wave has appeared in a wavy development. From the point of test scores, junior middle school second grade was in a low valley and the high school second grade was in peak. Youth and intimate degree is a significant correlation between a mother and a father, to moderate related. The male students had significantly higher intimacy status with fathers than the female students. |
