Background: There is scant literature on change of name among psychiatric patients but a more substantial amount on the use of aliases among offenders. No one to our knowledge has explored name changes among offender patients.
Aim: This study was undertaken to establish the prevalence of name change among high security hospital patients and to compare those who changed name with those who did not.
Hypothesis: It was hypothesized that name change would be associated with male gender, repeated offending and a diagnosis of personality disorder.
Method: The clinical records of all patients resident in one high security hospital on 31 January 2000 were searched. As all such patients are compulsorily detained, all name changes must be recorded. Any change prior to that date was also noted, together with basic demographic and diagnostic information; supplementary data were obtained from the special hospitals' case register.
Results: Seventy-one patients (17%) of the resident population changed names (exclusive of a woman changing her surname on marriage). Name changing was associated with disrupted upbringing. Patients with personality disorder were more likely to change names than those with psychosis, regardless of sex, age or ethnic group. Those with psychosis were more likely to select unusual or symbolic names.
Conclusions: On the evidence of previous literature, people from this serious offender patient population were more likely to change names than other psychiatric patients but less likely than non-mentally-disordered offenders. Changes by people with psychosis seemed related to their illness, whereas changes by those with personality disorder might reflect childhood disruptions in rearing patterns.
