The MCMI-III is the gold standard of psychological assessment tools designed to provide information on personality traits and psychopathology. My Primary alter was given the MCMI-III as part of a full day psychological inventory. After leaving his Gender Therapist because of her insistence that he was transsexual, the medical school Clinical Psychologist he started seeing next administered the test to try to find the source of his uncontrollable urge to look and act like a girl (At that time Primary didn't know about me, his girl alter, remember his childhood sexual and psychological abuse, or have a clue he had Multiple Personality/Dissociative Identity disorder).

The MCMI-III is an amazingly tool. It describes personality, clinical syndromes and can even tell if you lied when you answered the questions! It indicated our System's gender dysphoria, but Multiple Personality/Dissociative Identity disorder is a disorder of secrecy. The victim's life depends on their ability to hide what they are doing. The tool would have identified other psychoses related to trauma (PTSD, depression, anxiety, self harm) if we had them. But our System functions so well, the MCMI-III was unable to detect that we are DID.
