(Poly)Middelengebruik in Relatie tot Crimineel Gedrag: Een Scoping Review
Substance use and delinquent behavior like theft, violence and unacceptable sexual behavior is often mentioned in the same breath. The prevalence of substance use is higher in forensic populations and Tbs-populations (a Dutch forensic psychiatric hospital) compared to the general population. Nevertheless, there is still much unknown about the relation between substance use and criminal behavior and the literature at hand seems to be insufficient for a complex Tbs-population. The main goal of the study is to give an overview of existing literature about (poly)substance use and criminal behavior exposing gaps in knowledge. A scoping review is conducted in this context.After setting inclusion and exclusion criteria literature was screened in three steps; based on title, abstract and full-text. This resulted in 299 articles relevant for further synthesis.Results show that partner violence, property, violent, and unspecified crimes are the most researched criminal behavior in the literature. Most common substances are alcohol, cannabis, cocaine and heroin. Polysubstance use is found in a quarter of the studies and is often unspecified, if specified it mainly contains combinations of alcohol with other substances.There seem to be different reasons for existing knowledge gaps; some substances are more logic with criminal behavior.; some criminal behavior is less common. It turns out that the that the majority of the literature is about alcohol and cannabis what possibly comes at the cost of research about other substances.
