Valid instruments for the early identification of psychotic experiences (PE) and symptoms in youths are urgently needed for large-scale preventive interventions. A new section of The-Development-and-Well-Being Assessment (DAWBA) measuring child self-reported PE has yet to be validated. The current study aimed to investigate the concurrent validity of DAWBA-based self-reported PE (PE-S) with regard to interview-based measures of PE (PE-I).
Participants were 1571 (47.8% male) children of age 11 to 12 years from the Copenhagen Child Cohort 2000 (CCC2000) with complete data from both the online PE-section of DAWBA and the following face-to-face interview and assessment of PE. The DAWBA-PE-section asks the child 10 questions covering auditory and visual hallucinations, delusional ideas and subjective thought disturbances ever in life; and attributions to sleep, fever, illness or drug intake. The interview-based assessment of PE was performed by trained professionals using 22 items from The Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime Version (KSADS-PL). The two assessments were completed independently.
The prevalence of PE-S was 28.1% (24.3% for PE-S with no frequent attributions), compared with 10.2% for PE-I. The predictive values of PE-S for any PE-I were: sensitivity = 73.8%, specificity = 77.1%, positive predictive value (PPV) = 26.8% and negative predictive value (NPV) = 96.3%. Self-reported visual hallucinations had the best overall predictive values with a sensitivity of 43.1%, specificity of 94.0%, PPV of 44.8% and a NPV of 93.6% for any PE-I.
The DAWBA-section proved valuable as a screening tool for PE in the youth general population.
对于大规模的预防干预措施，迫切需要有效的工具来早期识别青少年的精神病性体验（PE）和症状。尚未验证用于测量儿童自我报告的 PE 的 DAWBA 的新部分。本研究旨在调查基于 DAWBA 的自我报告的 PE（PE-S）与基于访谈的 PE 测量（PE-I）之间的同时效度。
参与者是来自哥本哈根儿童队列 2000 年（CCC2000）的 1571 名（47.8%为男性）年龄在 11 至 12 岁的儿童，他们均完成了 DAWBA 在线 PE 部分以及以下面对面访谈和 PE 评估的完整数据。DAWBA-PE 部分向儿童提出了 10 个问题，涵盖了一生中听觉和视觉幻觉、妄想观念和主观思维障碍；以及归因于睡眠、发烧、疾病或药物摄入。PE 的基于访谈的评估由经过培训的专业人员使用来自儿童时期情感障碍和精神分裂症的时间表 - 现在和终生版本（KSADS-PL）的 22 个项目进行。这两个评估是独立完成的。
PE-S 的患病率为 28.1%（无频繁归因的 PE-S 为 24.3%），而 PE-I 的患病率为 10.2%。PE-S 对任何 PE-I 的预测值为：敏感性=73.8%，特异性=77.1%，阳性预测值（PPV）=26.8%和阴性预测值（NPV）=96.3%。自我报告的视觉幻觉具有最佳的整体预测值，其敏感性为 43.1%，特异性为 94.0%，PPV 为 44.8%，NPV 为 93.6%，适用于任何 PE-I。
DAWBA 部分被证明是青少年普通人群中 PE 的有效筛查工具。
