إستخدام نموذج راش في تقدير الخصائص السيكومترية لمقياس قلق المستقبل المهني للطلبة المقبلين على التخرج
The aim of the research is to identify the indicators of the validity of the professional future anxiety scale according to the Rasch model, to identify the indicators of the stability of the scale, and to determine the values of the estimates of the difficulty parameter for the paragraphs of the professional future anxiety scale according to the Rasch model. The research sample consisted of (91) male and female graduate students at the Faculty of Arts, Department of Psychology, specializing in (measurement, evaluation, and psychological counseling. The Professional Future Anxiety Scale for students about to graduate” (SAOFSCG) prepared by Meshri, Falah, Jawadi (2018) codified on the Algerian environment was used as a research tool. Among the most important findings of the research are the following : 1) The degree of conformity of the items with the partial estimation model was verified, the (Easy Estimation) program was used to analyze the data, and after deleting the responses of the students who fall outside the matching limits (0.50-1.5), and then the analysis was re-analyzed again, and the results showed that all the items and their number matched (35) paragraphs of the model, meaning that the value of the external or internal matching statistic corresponding to the estimates of the difficulty parameters for these paragraphs falls within the appropriate matching limits (0.5 - 1.5). Where the highest value of the external matching was (1.489) and the lowest value was (0.565) with an average (0.927) and standard deviation of (0.232), the highest value of the internal matching was (1.496) and the lowest value was (0.622) with an average (0.978) and standard deviation of (0.221). And this result is consistent with the result of the study of Aunt et al, 2020), which indicated that all items conform to the partial estimation model. 2) The difficulty parameter was calculated for the future anxiety scale that was developed according to the partial estimation model, and we note that there are 4 relative difficulty parameters for each item at the level of all items, and the values of the first relative difficulty parameter ranged from (-0.793) to (-2.438) with an arithmetic average of (-1.380) and a standard deviation of (0.326), while the values of the second relative difficulty parameter ranged from (0.314) to (-1.229), with an arithmetic mean of -0.417) and a standard deviation of (0.357), while the values of the third relative difficulty parameter ranged from (1.144 to -0.695) with an arithmetic mean (0.274) and a standard deviation (0.428), while the values of the fourth relative difficulty parameter ranged from (2.026) to (0.069), with an arithmetic mean (1.172) and a standard deviation (0.487).
