Sexual or physical abuse of children are discussed as possible causes or risk-factors for psychiatric disorders like posttraumatic stress disorder, alcohol and drug addiction. The aim of this study was to identify possible differences between sexually or physically abused and non-abused patients with polytoxic drug abuse.
Method: 100 patients with polytoxic drug abuse were interviewed during their therapy about a history of sexual abuse prior to the age of sixteen. Using different questionnaires we tried to find possible differences between drug users being sexually abused or not and risk factors for later drug addiction.
Results: 70% of the female and 56% of the male drug users had been sexually abused as children, 40% of the male and 50% of the female participants had a history of severe sexual abuse with sexual intercourse. In over 50% friends or relatives were the perpetrators committed the crime, in no case the parents had. More than 40% showed also a history of physical abuse. Significantly more drug users than alcohol abusers had a sexual trauma. Especially severe sexual abuse was associated with abuse of hard illegal drugs. Furthermore, we could find significantly more symptoms such as autoaggressive and suicidal behaviour, social isolation, reduced emotional binding to others, tendency to be persistently victimized, prostitution and violence against others in the group of sexually abused. Many of these symptoms are not only characteristic of addiction, but can be found also in other psychiatric diseases such as borderline and eating disorder. In conclusion, we could not find a significant correlation between sexual abuse and later drug addiction. 80% of the drug users themselves did not relate the fact of being sexually abused as child to later drug abuse. However, there seems to be a positive correlation between sexual abuse and a more severe addiction to illegal drugs as well as higher rates of symptoms with a negative course of the disease. For this group of patients with an unfavourable prognosis special therapeutic concepts are needed.
