There is an 24 item questionnaire about personality and I want the way of calculating the final score for each person. In attached file , in last page you can find the questionnaire.
Dear Mozghan,
As An statistician (Better say Just an statistics student ) :) I was familiar just with Likert scale, But After I saw your question I read the questionnaire you linked in your question. If you look exactly at that, It used a psychological Scale named EPQR-S Scale. With and exact look at questions you can see that answer of the questions can Be just Yes or No (So Values of Each person can be 1 and 0) in this Scale. So The individual score of each person in each scale is count of Yes Questions (count of 1s) and therefore maximum score of each person in each scale will be 12.
You may as what is the decimal numbers in the article you mentioned, I should say they are average of 0 and 1 numbers in each country volunteers score in study.
For more confident I advice you too take a look at this article.
If I said it vague Please let me know,

What you have are the items from the short form of the Eysenck Personality Questionnaire - Revised (EPQ-R). This is actually a 48-item measure.
The first thing to note is that when you type this up (I'm assuming you want to use it), the items should be in numerical order. Item numbers are printed to the left of each item in the table, but the items have been rearranged so that they are grouped by scale.
Next to each item you should print the words YES and NO. The instructions are to respond to each item by circling YES or NO, depending on whether you (the test-taker) think the statement is true of you.
Each item answered in the keyed direction is scored +1. The others are scored 0.
Most items are written so that a YES response is scored +1. However, there are some reverse-scored items. Items #27 and #41 on the Extraversion scale. Items #2, #6, #18, #26, #28, #35, and #41 on the Psychoticism scale. Items #8, #12, #20, #24, #29, #33, #37, #40, #45 on the Lie scale. I think all the Neuroticism items are keyed to YES.
Double-check those numbers. The items in question should pretty obviously be "going the wrong way," so to speak. For example, extraversion is all about being sociable, energetic, and assertive - so a high-extraversion person would NOT tend to be quiet when with other people.
Dear Saleh and Stephan,
I understood the way of calculating the scores, but the main question is how to label cases based on the scores, extroverted or introverted? how can I give a personality trait to each case?
The trait scores are dimensional. It isn't that one person is "an extravert" while another is "an introvert." Rather, the higher (or lower) one's score on a scale, the more one inclines toward the characteristics typical of that extreme. For most purposes, you're better off retaining the information contained in these scores that would be lost if you assign everyone to one "type" or another. But if you wish, you may use a median split or some other such procedure to create an artificial dichotomy.
Please, do you know how to assess SPQ-RA (abbreviated, 24 items)? I have the questionnaire and the direct data of a sample but the test correction template is at my university (University of Valencia, Spain) which it's closed due to coronavirus and no one can enter the Docimotheca :(
Surprised I even saw this, Esperanza! If you mean the Schizotypal Personality Questionnaire, Brief Form, Revised, then A.A. Davidson et al. (2016) might well be your ticket. The full text is available at: Article Schizotypal Personality Questionnaire-Brief Revised (Updated...
I think the full text of the instrument, with scoring info, is in Supplement #1
Hi, thanks, but not, I mean the short version (24 items) of the Eysenck Personality Questionnaire - Revised (EPQ-R),
I can't transform the direct scores to interpretate them because I can't get now the template to do it :(
