Although there currently exists a large amount of research on the characteristics and treatment of psychopathic disordered (PD) sex offenders, little if any empirical studies have addressed the mentally ill (MI) and mentally handicapped (MH) offender populations. A total of 106 PD, MI, and MH sex offender records from Rampton (Special) Hospital were reviewed for the study. Offender categories were compared by age of first documented sex offence, IQ at the time of admission, sex offence type, frequency of each offence type, history of violence during sex offences, age and gender of sex offence victims and number of victims for age and gender. Results revealed that 88 per cent of PD, 98 per cent of MI, and only 56 per cent of MH offenders' victims were female. Further analysis revealed that PD and MI offenders' victims were primarily female, with the largest proportion being pubescent and adult females. MH offender victims were primarily males and females under the age of 16. IQ correlated positively with history of violence during sexual assault and mean IQs were higher for 'violent' than 'non-violent' offenders in each offender category. A discussion of these and other significant findings, as well as implications for clinical treatment, is presented.
In order to study whether pseudomemories represent actual memory distortions or are a result of response bias, 60 highly hypnotizable subjects and subjects from the general population were divided into 4 experimental groups and were tested for pseudomemory manifestation after receiving a false suggestion. Of the 4 groups of subjects, 3 were offered a monetary reward as a motivation to distinguish false suggestion from actual occurrence. Pseudomemory manifestation was found to be significantly higher among subjects not offered a reward than among subjects who were offered such an reward. The implications of these findings are discussed.
The prevalence of history of head trauma along with reported sequelae as a result of such in this sample suggests that head trauma may certainly be a significant factor in persons presenting for substance abuse treatment. Assessing for a history of head trauma and associated sequelae in persons presenting in substance abuse treatment programs may be clinically appropriate as such sequelae have been found to adversely affect treatment progress. Further discussion on implications of the results of this research as well as discussion on further research in the area are provided.
Objectives:To determine the base rate of traumatic brain injury (TBI) in adults admitted to state psychiatric hospitals. Participants: A total of 3,133 psychiatric patients between the ages of 18 and 60 years old from 7 state facilities were screened for TBI and associated sequelae during a 3-year study period. Method: Comprehensive medical chart/documentation review and treating psychiatrist assessment. Results: A total of 524 (16.73%) had a documented history of TBI, 195 (6.22%) held a previous diagnosis of organic mental disorder at time of admission, 57 (1.82%) had clinical symptoms considered to be consistent with TBI sequelae, and 201 (6.42%) were diagnosed with dysfunction of thinking secondary to TBI. Conclusions: Findings support specific assessment for TBI in these populations, especially in light of previous studies suggesting that psychiatric patients with a history of TBI may require more specialized treatments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
