To examine inter- and intra-rater reliability in the assessment of genital findings in cases of suspected child sexual abuse.
Colposcopic photographs of the external genitalia of 70 female children were independently assessed by child sexual abuse teams in Auckland and Sydney. For the Auckland centre, intra-rater reliability was assessed by making a second independent assessment 6 months following the first. Reliability was quantified using per cent of agreement and Cohen's Kappa statistic.
There were high levels of inter- and intra-rater agreement. When photographs were classified as normal/non specific or strongly indicative of child sexual abuse, there was 93% agreement between the Auckland and Sydney teams with a kappa score of 0.70. For the two separate ratings made by the Auckland team there was 94% agreement with a kappa score of 0.75.
The high levels of inter- and intra-rater agreement obtained in this study were reassuring. The results obtained compare favourably with the results of reliability studies in other areas of medical practice.
在疑似儿童性虐待病例中，检查评估生殖器检查结果时的评分者间信度和评分者内信度。
奥克兰和悉尼的儿童性虐待评估小组对70名女童的外阴部阴道镜照片进行了独立评估。对于奥克兰中心，在首次评估6个月后进行第二次独立评估，以此来评估评分者内信度。使用一致百分比和科恩卡帕统计量对信度进行量化。
评分者间和评分者内的一致性水平很高。当照片被分类为正常/非特异性或强烈提示儿童性虐待时，奥克兰和悉尼小组之间的一致性为93%，卡帕值为0.70。奥克兰小组进行的两次单独评分之间的一致性为94%，卡帕值为0.75。
本研究中获得的评分者间和评分者内的高一致性令人安心。所得结果与医学实践其他领域的信度研究结果相比具有优势。
