Abstract

BACKGROUND: Little population-based evidence exists about the characteristics of first disclosure of child sexual abuse (CSA), including age and delay. OBJECTIVE: To generate population-based evidence about the age of first disclosure, delay to first disclosure, first recipients, and feelings of support. PARTICIPANTS AND SETTING: The Australian Child Maltreatment Study collected information about CSA victimization from a nationally representative sample of 8503 individuals aged 16 and over. CSA prevalence was 28.5 %. Almost one half of these individuals (45.2 %) had never disclosed their experience of CSA before participating in the survey. Slightly over one half (54.8 %) of these individuals had disclosed before participating, and provided information about the characteristics of their first disclosure. METHODS: We generated national estimates for age of first disclosure, delay to first disclosure, first recipients, and feeling supported, and compared results by gender and age group. RESULTS: Among individuals who disclosed, 70.2 % first disclosed before age 18, comprising more women (73.7 %) than men (60.4 %); and with participants aged 16-24 more likely (81.2 %) than people aged 25-44 (67.8 %) and 45 or more (68.7 %). Among individuals who disclosed, almost half (45.6 %) first disclosed within a year; the median delay was 1 year and the mean delay was 7.1 years. One in 10 people aged 25 or more (11.1 %) delayed more than 20 years. First recipients were typically mothers (30.9 %) and friends (24.9 %). Most people felt supported (79.8 %), especially those aged 16-24 (87.3 %). CONCLUSIONS: We identified significant trends in CSA disclosure characteristics. Many people first disclose in childhood, often within a year. Yet, many only disclose in adulthood, after a long delay. While disclosure is becoming more common, measures are required to facilitate disclosure and supportive responses. Findings have implications for health, education and legal systems.
