A cloud-based flexible solution for psychometric tests validation, administration and evaluation

Psychological tests generally provide an evaluation scale to evaluate whether or not the subject manifests some traits. Such kind of tests are generally used for attitude evaluation, personal selection, educational and rehabilitation purposes, as well as for the diagnosis of cognitive disorders. The use of test and other questions-based diagnostic tools, represents one of the main and principal actions in order to start a clinical and therapeutic path, as well as for the evaluation and assessment of the possible educational and rehabilitation effort. Unfortunately such tests are generally the result of a long and difficult process of validation for their standardization, simplification and reorganizations driven by operations performed by means of complex statistical methods. In the work presented on this paper we developed a unified cloud-based resource for the management and execution of all the task related to psychometric testing, from the creation of a test, to its validation and use. The solution has been designed to grant maximum flexibility allocating resources on a cloud service. Such resources can be used as a remote support for the psychologists designing and administering the test, as well as computing platform to unburden the single terminals of the heavy computations required during the standardization procedure. Moreover, by means of the distributed database, our solution is also able to support the simplification and reorganization process, as well as to serve as online platform for the administration and consequent scoring of the finalized and standardized test.
