TPI and CSE scales

[Denis Fitzpatrick-3]

Hi all

Just wondering if anyone has any experience of using Gosling et al. (2003). TPI scale. A very brief measure of the Big Five Personality Domains  

and

Judge et al (2003) 12 question Core Self Evaluations (CSE).

I know that even number questions are reverse scored.

However, does anyone know if

1. CSE can be totaled

2. TPI  can be totaled
