Comorbidity profiles: a latent class analysis of Swedish forensic psychiatric patients with substance use disorder

COMORBIDITY PROFILES - A LATENT CLASS ANALYSIS OF SWEDISH FORENSIC PSYCHIATRIC PATIENTS WITH SUBSTANCE USE DISORDERS.

Four distinct comorbidity profiles were identified among individuals with substance use disorder for whom forensic psychiatric care was recommended, and injection drug use, previous suicide attempts, and prior receipt of substance use support significantly predicted class membership.

The study aimed to characterize the clinical features of individuals undergoing forensic psychiatric assessment in Sweden who had a co-occurring substance use disorder (SUD). A total of 199 individuals with substance use disorder for whom forensic psychiatric care was recommended were included from forensic psychiatric assessments conducted in 2021-2022; psychiatric, criminal, substance use, and care-related variables were collected, and latent class analysis was performed alongside univariable and multivariable logistic regression. The sample was 89% male, with a median age of 31 years (range 19-70); 86% had a psychotic disorder, 19.6% a personality disorder, 12.5% autism, intellectual disability, or a cognitive disorder, and 10% a mood disorder. Regarding substance use, 58.3% had cannabis use disorder, 41.7% central nervous system stimulant use disorder, 25.1% alcohol use disorder, and 20.6% sedative or opioid use disorder; lifetime injection drug use was reported in 20.6%. Before the index offense, 95.5% of individuals had had contact with psychiatric care at some point in their lives, and 85.4% had received substance use care through healthcare or social services; lifetime suicide attempts were identified in 34.7%, reported self-harm in 16.6%, and an assessed history of adverse childhood experiences in 67%. The four-class model provided the best fit: 1) schizophrenia and multiple substance use disorders, 2) autism, intellectual disability, or a cognitive disorder with unspecified substance use disorder, 3) personality disorder and multiple substance use disorders, and 4) other psychoses and cannabis. Factors significantly associated with class membership were injection drug use (classes 2 and 3), previous suicide attempts (classes 2 and 3), and prior receipt of substance use support (class 4); the authors state that the findings support profile-tailored, integrated care planning that addresses psychiatric disorders and co-occurring substance use together.
