Best approach of reliability

Hi If im trying to measure the reliability of my test, which is aimed to measure defense mechanisms. and theres 2 types of defense mechanism, for example avoidance and emotional support, what is the best approach of reliability I should use? is my test considered unidimensional?


Can't make spagetti
To test for this you'd need to conduct some type of Factor Analysis or Structural Equation Modelling on the items of your test.
