Abstract :
[en] Dual Diagnosis is a key topic in the treatment of
patients with intellectual disability (ID) in forensic hospital.
These patients are hospitalized under Belgium's Social
Defense Law, an undetermined measure confinement of
persons recognized as incapable of controlling their actions
owing to mental disorder. Although, heterogeneity of
psychiatric disorders among intellectual disabilities patients
is highlighted, there are few available literature on Dual
Diagnosis among forensic patients. Data suggest that
psychiatric comorbidity is more the rule than the exception
among forensic populations. This study specifies the
psychiatric and criminological characteristics of Dual
Diagnosis forensic inpatients. Methods: We compared an
ID forensic patients group (total IQ <70; N =67) to a no ID
forensic patients group (total IQ> 70, N =105). IQ was
evaluated with the WAIS-III or WAIS-IV. Mental disorders
were assessedwith theMINI and the SCID-II.The offenseswere
brought out of criminal records. Age, Length of stay and social
characteristics were also considered in the analysis. Results:
Data Analyzes identify the prevalence of Dual Diagnosis and
specify the diagnosis comorbidity prevalence and their
associations with criminological characteristics. Conclusions:
These results are discussed in the light of the scientific literature
and clinical implications.We also discuss the incremental
difficulties of care forDualDiagnosis forensic patients in terms of
treatment but also of social rehabilitation. References:Moniteur
