The big caveat about this study is that it's not a random sample. Not even close.
Still, it's interesting.
The disclosure of widespread sexual abuse committed by professional educators and clergymen in institutions in Germany ignited a national political debate, in which special attention was paid to church-run institutions. We wanted to find out whether the nature of the abuse and its effect on victims differed depending on whether the abuse had been experienced in religiously affiliated versus secular institutions.
In 2010, the German government established a hotline that victims could contact anonymously to describe their experiences of sexual abuse. The information provided by callers was documented and categorized. Our analysis looked at a subset of the data collected, in order to compare the nature of the abuse experienced at three types of institutions: Roman Catholic, Protestant, and non-religiously affiliated. Non-parametric tests were used to compare frequency distributions, and qualitative data were analyzed descriptively.
Of the 1050 victims in our sample, 404 had been in Roman Catholic, 130 in Protestant, and 516 in non-religious institutions. The overall mean age at the time of reporting was 52.2 years. Males (59.8%) outnumbered females. Victims who had been in religiously affiliated institutions were significantly older than those who had been in secular institutions. Almost half the victims had been abused physically as well as sexually, and most victims reported that the abuse had occurred repeatedly and that the assaults had been committed by males. Patterns of abuse (time, type, and extent), and the gender of the offenders did not differ between the three groups. Intercourse was more frequently reported by older victims and by females. Similar percentages of victims in all groups reported current psychiatric diagnoses (depression, anxiety disorders, PTSD). Significantly more victims from Protestant institutions reported having current psychosocial problems.
The results suggest that child sexual abuse in institutions is attributable to the nature of institutional structures and to societal assumptions about the rights of children more than to the attitudes towards sexuality of a specific religion. The exploratory data arising from this study may serve as a starting point for building hypotheses, and may point the way toward improvements in prevention and intervention strategies.
