Childhood maltreatment is a robust risk factor for psychosis, but it remains unclear whether different measurement methods provide equivalent validity in predicting psychotic symptoms. This study compared the predictive validity of two common indices of maltreatment at age 12-children's self-report and Child Protective Services (CPS) reports-on the development of psychotic symptoms at age 18 using data from a large, multisite longitudinal study ( = 629). Consistent with prior research, agreement was low between indices, with the prevalence of self-reported maltreatment being 2-3 times higher. A quarter of the sample endorsed at least one psychotic symptom at age 18, most commonly delusions. While CPS-indicated maltreatment was generally not associated with later psychotic symptoms, all forms of self-reported maltreatment were. Sexual abuse demonstrated a particularly strong relationship with psychosis, especially hallucinations. These results suggest that self-reports may provide stronger predictive validity than CPS indications of maltreatment in the assessment of psychosis risk, indicating that a child's interpretation of trauma matters more than the traumatic event itself in this regard.
童年期虐待是精神分裂症的一个强有力的风险因素，但目前尚不清楚不同的测量方法在预测精神病症状方面是否具有同等的有效性。本研究使用来自一项大型多地点纵向研究的数据（n=629），比较了两种常见的 12-13 岁儿童虐待指标（儿童自我报告和儿童保护服务报告）对 18 岁时精神病症状发展的预测有效性。与先前的研究一致，这些指标之间的一致性较低，自我报告的虐待发生率是后者的 2-3 倍。四分之一的样本在 18 岁时至少出现一种精神病症状，最常见的是妄想。虽然儿童保护服务报告表明的虐待通常与后期的精神病症状无关，但所有形式的自我报告的虐待都有关系。性虐待与精神分裂症的关系尤其强烈，尤其是幻觉。这些结果表明，在评估精神病风险时，自我报告可能比儿童保护服务报告的虐待更具有预测有效性，这表明在这方面，孩子对创伤的解释比创伤事件本身更重要。
