The SCID-II does not measure personality traits. However, I'm not sure that's what you want to do. You say something about "personality disorder traits" that makes me think you're solely concerned with psychopathology & diagnostics. (Yes, the DSM allows one to state that a patient has, say, "paranoid traits" when they fall short of meeting criteria for the diagnosis.) The SCID-II will work for this purpose about as well as it does diagnostically. Now, here it makes a difference whether you are using only the SCID-II questionnaire or following up with the SCID-II interview. The questionnaire alone should NOT be relied upon to make a diagnosis. That requires administration of the semi-structured interview by a trained clinician.

If you do want to measure normal personality traits (such as extraversion, neuroticism, etc.), then the SCID-II is wholly inappropriate. You may want to look into the NEO-PI-3, 16PF, EPQ-R, or any of a number of other instruments designed for this purpose.

 Thank you very much for your guidance. The response was very helpful. Please introduce a resource on how to score SCID-II .Which determines the cutting scores for the diagnosis of the disorder and the trait.

I believe it just follows the DSM (whichever edition your version of the SCID-II is based on - probably DSM-IV). In other words, each item represents one criterion (or symptom). So if the cutoff is, say, 5 criteria, then anyone affirming 5 or more can be considered a "case."

Thank you very much

Maryam, I agree with Stephen regarding the difference between personality disorders and personality traits. Is your purpose to evaluate patients or is this research focused? The measures that Stephen recommended are great. In clinical samples (e.g. patients), I typically employ the MCMI-IV or PAI due to diagnostic consistency with the DSM V. However, outside of the US, you will also need to consider cultural differences as the majority of these measures are normed on US samples. 

In line with the III section of DSM-5, I suggest you the GAPD (General Assessment of Personality Disorder; Livesley, 2006). It is a very useful self-report questionnaire designed to evaluate severity, differentiating personality disorders from personality traits (intended as normal personality variations), that are on a continuum.

have a nice day!

Thank you for your useful response. How can i access to GAPD?

Here is the main publication related to the GAPD. It includes contact information for the authors; ask them for a copy of the measure itself. But please be aware that it is not designed specifically to assess DSM personality disorders, though it does a pretty good job of identifying people who may be diagnosed with a personality disorder.

Thank you very much
