Prevalence of behavioural and emotional problems in primary school children was examined 4 years after a baseline survey at preschool age. The scope of symptoms was investigated. Due to anonymity of data only group differences between the two measurements were reported.
A representative sample of 1,481 children in fourth year primary school was assessed with the Child Behaviour Checklist (CBCL). In addition to the CBCL broadband groups of internalizing (INT) and externalizing symptoms (EXT) a third group of combined internalizing and externalizing symptoms (COM) was defined.
The 6 month prevalence of child mental health problems at second wave was 18%-a significant increase on the previous baseline rate of 12.4%. Of those 18% of children with child mental health problems 27.3% had exclusively internalizing, 6.0% externalizing symptoms and 52.4% had combined symptoms of INT and EXT.
The increasing prevalence was associated with an increase of symptoms of the broadband groups INT and COM but not EXT. The results also highlight an age and gender specific vulnerability of boys, both at preschool and primary school.
在对学龄前儿童进行基线调查4年后，对小学生行为和情绪问题的患病率进行了检查。对症状范围进行了调查。由于数据匿名，仅报告了两次测量之间的组间差异。
使用儿童行为检查表（CBCL）对1481名小学四年级儿童的代表性样本进行评估。除了CBCL内化（INT）和外化症状（EXT）的宽带组外，还定义了第三组内化和外化症状组合（COM）。
第二波儿童心理健康问题的6个月患病率为18%，较之前12.4%的基线率显著增加。在那些有儿童心理健康问题的18%儿童中，27.3%仅有内化症状，6.0%有外化症状，52.4%有INT和EXT的组合症状。
患病率上升与宽带组INT和COM症状增加有关，但与EXT无关。结果还突出了男孩在学龄前和小学阶段特定的年龄和性别易感性。
