Most previous studies on disclosing child sexual abuse (CSA) have either been retrospective or focused on children who already have disclosed. The present study aimed to explore the overall CSA disclosure rate and factors associated with disclosing to adults in a large population-based sample. A representative sample of 11,364 sixth and ninth graders participated in the Finnish Child Victim Survey concerning experiences of violence, including CSA. CSA was defined as having sexual experiences with a person at least five years older at the time of the experience. Within this sample, the CSA prevalence was 2.4%. Children reporting CSA experiences also answered questions regarding disclosure, the disclosure recipient, and potential reasons for not disclosing. The results indicate that most of the children (80%) had disclosed to someone, usually a friend (48%). However, only 26% had disclosed to adults, and even fewer had reported their experiences to authorities (12%). The most common reason for non-disclosing was that the experience was not considered serious enough for reporting (41%), and half of the children having CSA experiences did not self-label their experiences as sexual abuse. Relatively few children reported lacking the courage to disclose (14%). Logistic regression analyses showed that the perpetrator's age, the age of the victim at the time of abuse, and having no experiences of emotional abuse by the mother were associated with disclosing to an adult. The results contribute to understanding the factors underlying children's disclosure patterns in a population-based sample and highlight the need for age-appropriate safety education for children and adolescents.

Few studies have explored the disclosure of child physical abuse although child sexual abuse disclosure has been widely studied and debated for years. The present study explores the characteristics of child physical abuse disclosures and compares them to previously published findings on child sexual abuse disclosure from the same data. The data consist of a representative sample of 11,364 sixth and ninth graders. Participants responded to a wide variety of questions concerning experiences of violence, including child physical abuse and child sexual abuse, in the Finnish Child Victim Survey conducted in 2013. Within this sample, the prevalence of child physical abuse was 4.1%. Children reporting abuse experiences also responded to questions regarding disclosure, reactions encountered during disclosure, and potential reasons for nondisclosure. Findings show that most of the children who disclosed physical violence had disclosed to their mother. The overall disclosure rate of child physical abuse was 74%. However, only 42% had disclosed to adults, and even fewer had reported their experiences to authorities (12%). The most common reason for nondisclosure was that the youth did not consider the experience sufficiently serious to report (53%). These findings were largely in line with the child sexual abuse disclosure rates in our previous study. Analyses of variables associated with disclosing to an adult indicate that the strongest factors predicting disclosure to an adult are younger age, female gender, no previous experiences of child physical abuse, and parents knowing who their child spends her or his spare time with. Implications for further research and practice are discussed.
