In the actual study done by Dunn et al. (1994), questionnaires were sent out to approximately one-thousand psychologists and psychiatrists surveying their attitudes towards dissociation, with an emphasis on multiple personality disorder.  The study resulted in 97.5% of the practitioners indicating they believed in dissociation disorders, 80% reported they believed in the existence of multiple personality disorder, 12.3% did not believe in multiple personality disorder, and 7.7% were unsure. The total of 80% is a high percentage for clinicians who believe in the disorder. source

Take a Personality Test

There are many versions of personality tests on the web.  This is one that is suggested for all your alters to compare.


Dissociative identity disorder frequently co-occurs with other psychiatric diagnoses, such as anxiety disorders (especially post-traumatic stress disorder-PTSD), mood disorders, somatoform disorders, eating disorders, as well as sleep problems and sexual dysfunction.[3] Dissociative identity disorder has been found to more commonly occur with particular personality disorders including Avoidant Personality Disorder (76% co-morbidity), Self-defeating Personality Disorder (68% co-morbidity), Borderline Personality Disorder (53% co-morbidity) and Passive-Aggressive Personality Disorder (45% co-morbidity).[68] Schizotypal Personality Disorder also had a 58% crossover with dissociative tendencies.[68]


"True prevalence is unknown; however, dissociative identity disorder has been shown to be more common than previously thought. Abuse may be the hidden feature in patients who are the most difficult to diagnose and treat. In 1984, by studying psychiatric inpatient charts, Carmen et al and Mills et al proposed a relationship between history of abuse and certain indicators of the severity of psychiatric symptoms." source

Statistics regarding [DID]disorder indicate that the incidence of DID is about 3% of patients in psychiatric "hospitals and is described as occurring in females nine times more often than in males. However, this female preponderance may be due to difficulty identifying the disorder in males. Also, disagreement among mental-health professionals about how this illness appears clinically, and if DID even exists, adds to the difficulty of estimating how often it occurs." source
