Linear Congruential Method for Randomization of Test Item in Computer-Based Psychological Edwards Personal Preference Schedule (EPPS) Test

Abstract

Psychological tests are used to determine human's attitude and behavior. In its application, psychological tests still use the old method. Objects are asked to answer questions and then the answers will be collected again to be calculated, and then conclusion will be drawn from the result. It will be time consuming and impractical. Computer-based psychological test have an answer to these deficiencies. By utilizing the ease of test item management in computer, this paper discusses the application of linear congruential method for randomization of test item in computer-based psychological edwards personal preference schedule (EPPS) test developed by web-based programming. According to expert, the difference in the number of respondents who have the largest and smallest raw score aspects that are the same and not the same is considered not too significant that in this case randomization of test item can be applied to the EPPS test because the change in test results is not too significant and the scoring process is still valid.
