بناء مقياس لأنماط الشخصية لدى طلبة الجامعيين وفق نظرية يونغ

Abstract EN

This study aimed at constructing a Personality Types Inventory (PTI) based on Jung’s Theory.

To achieve this aim, an initial version of the PTI was constructed by the researchers.

This version consisted of 118 items, which describe the respondent and cover four subscales, each on a three-point Likert scale.

The scale was then administered to 335 students.

Factor analysis results indicated that the unidimensionality of the scale had not been achieved with four subscales, indicating that the measure is multidimensional, and the dimensions are not correlated.

It was also found that the loading value of 56 items was higher than 0.40.

The final version of the scale (56 items), displayed good psychometric properties, where the total internal consistency reliability coefficient of the scale was 0.91.

Furthermore, an evidence of the measure's validity was also found.

Results showed that the items possess discriminative ability, where a significant difference was found between the means related to all items of the Personality Types Inventory by category, with the upper category scoring higher, showing the discriminative ability of the PTI items.
