English Abstract

Classical Test Theory is facing some Obstacles in dealing with Contemporary Psychometric problems, this has led to limited and the Lack of Effectiveness of this Theory in many developed Practical Applications.

The Modern Theory (IRT) have emerged as an Attempt to Treatment these Obstacles.

Therefore, Current Research aims to use one of (IRT) Unfolding Models (Generalized Graded Unfolding Model - GGUM) to determining the Measurement Characteristics of the Multidimensional Iowa Suggestibility Scale (MISS), and adapted it to the local Environment.

To achieve these, has been started with translation procedure of the scale, and adapted to the local environment.

To ensure the Clarity of the Instructions and Items, offered the Scale to a group of the Specialization Arbitrators.

All Items showed Valid and Appropriate to describe the Triad Measured.

Then the Scale was administrated to a Random Sample of the same Statistical analysis Population.

It showed that the instructions and Items are clear, and has been identified (15) minutes rapt as a time to answer.

After that make sure Researcher Appropriate the scale was applied to a statistical analysis sample consisting of (1,000) students were selected in a Proportional Stratified Sampling Method, and to ensure an Appropriate Scale of Statistical Analysis of the data has been verified Model Assumptions (Undimensional, and Local Independence) through Procedures of (Factor analysis) that Represented by Criteria (Variance Ratio Interpreter, Egen- Value, and Items Loading) of the Dominant Factor.

That was showed that the Appropriate Data for statistical analysis According to the (GGUM) Model by using Computerized Program (GGUM-2004).

The Results after removal Responses of (40) individual of statistical analysis, showed that the extent of location paragraphs (DELTA) ranging from (3.178) to (-2.378), and the its discriminatory (ALPHA) ranged from (2.692) to (0.556), this is for parameters paragraph, and the Person's Ability (Theta) ranged from (2.969) to (-3.271).

The Results also showed that all Items verify (INFIT) and the distant (OUTFIT), and the (G2) Values of levels Likelihood Ratio for (Items), ranged between (5.997) to (40.107), while for Total scale, (G2) Value reaching (1347.347) with (df -364).

Each of the above are indicators of (Fit Validity) Total Scale, and before achieved (Descriptive Validity).

For the rest of Psychometrics, the researcher has adopted several Indicators to identify the Reliability of Scale, the Reliability of the Information reaching (0.982), while the Reliability of Separation Coefficient (G) of Sample has reached (0.991), and.

The (G) relating to Scale was (0.99).
