The objective was to describe observed differences between the official Danish Strengths and Difficulties Questionnaire (SDQ)-norms and data from a sample based on the Danish National Birth Cohort (DNBC) including children born between 1996 and 2003. We compared the risk classification, cut-off bandings and the group sizes between the Danish norms and the values found in our sample at ages 7, 11 and 18 years.
Two sets of norms are used in Denmark: Arnfred's norms, based on a sample from one single Danish municipality and Niclasen's norms, based on multiple Danish cohorts, including the DNBC. Inconsistencies were found between banding scores in the two existing norms and the banding scores identified in our sample from DNBC: discrepancies included banding scores for several of the problem scales for children and preadolescents. For adolescents, we found less apparent inconsistencies between Arnfred's sample and the DNBC. Results demonstrate that the existing SDQ norms do not apply well to a large-scale cohort sample in Denmark. The usefulness of the SDQ as a screening instrument for mental health problems depends on appropriate norms. We therefore urge that the current Danish SDQ norms are used with caution, and preferably they should be revised.
本研究旨在描述丹麦官方版优势与困难问卷（SDQ）常模与基于丹麦国家出生队列（DNBC，涵盖1996年至2003年出生儿童）样本数据之间观察到的差异。我们比较了丹麦常模与我们在7岁、11岁和18岁样本中所发现数值之间的风险分类、截断区间及组群大小。
丹麦使用两套常模：基于丹麦一个单一市镇样本的阿尔弗雷德常模，以及基于包括DNBC在内的多个丹麦队列的尼克拉斯en常模。在这两套现有常模的区间分数与我们从DNBC样本中确定的区间分数之间发现了不一致之处：差异包括儿童和青少年几个问题量表的区间分数。对于青少年，我们发现阿尔弗雷德样本与DNBC之间的不一致不太明显。结果表明，现有的SDQ常模不适用于丹麦的大规模队列样本。SDQ作为心理健康问题筛查工具的有效性取决于适当的常模。因此，我们敦促谨慎使用当前丹麦的SDQ常模，最好对其进行修订。
