The Difference of Two Application Methods (Manual and Electronic) and Their Effect on the Personality Metrics Psychometric Properties: A Structural Equation Model

This study aimed to compare the psychometric properties between two methods in the application of personality metrics (manual and electronic). To achieve this aim, researchers used the power of personality scale prepared by Alwalidi and Arnout (2016), which consists of (90) items distributed equally over six dimensions, each dimension consists of (15) items. This scale was applied to a sample consisted of (200) male and female students from Zagazig University, their ages ranged between 19 to 25 years. The researchers used the design of repeated measurements in the application of the procedures of the scale two forms (manual and electronic) on a sample of (200) students, was divided into two groups, by (100) students in each group according to the form of the scale (manual or electronic) the respondent receives the two forms, in a different order from one group to another. The psychometric properties related to the items represented by (item discrimination, and the validity of the items) and the psychometric properties related to the scale represented by (reliability) were calculated. The study found that the electronic application method was superior to the manual application method. Therefore the results recommend using the electronic method of application when initiating the construction or application of personal metrics.
