Timing and chronicity of child maltreatment in Germany: results from a representative sample.

Objectives: Child maltreatment (CM) is a major risk factor across the lifespan. While research on CM and its consequences has risen strongly during the last decades, research is mainly focused on the prevalence of types of CM incidents. As valid prevalence rates on timing and chronicity of CM are lacking to date, we aimed to assess the timing of experienced CM by describing the age of onset, duration, and prevalence at each year of age for each CM subtype in a population-based sample.

Study Design: Cross-sectional, observational study in a representative sample.

Methods: Using different sampling steps including a random route procedure, a probability sample of the German population above the age of 16, encompassing 2514 persons (50.6% female, mean age: 50.08 years) was generated. Participants were asked about sociodemographic information in a face-to-face interview, CM was assessed using the ICAST-R questionnaire.

Results: The earliest mean age of onset was seen in neglect with 8.07 (±3.07) years for boys and 7.90 (±2.96) years for girls, while the mean age of onset for sexual abuse was in adolescence with 13.65 (±3.86) years for boys and 13.91(±3.17) years for girls. The overall duration of CM was lowest for sexual abuse with 2.12 (±2.01) years for boys and 2.35 (±1.73) years for girls, the highest duration was seen for emotional abuse with 4.00 (±3.54) years for boys and 4.21 (±3.77) years for girls.

Conclusions: Our novel results provide important epidemiological information for prevention efforts.
