It is unclear whether the structure of obsessive-compulsive disorder (OCD) symptoms seen in adults is preserved in pediatric samples.
A total of 238 children and adolescents referred to a specialty pediatric OCD clinic were administered the Children's Yale-Brown Obsessive Compulsive Scale Symptom Checklist, and its 13 major symptom categories were subjected to exploratory principal components analysis. The resulting factors were correlated with relevant clinical variables.
Principal components analysis identified four symptom dimensions explaining 55% of the total variance and broadly corresponding to those seen in adult samples. Boys were more likely to have sexual obsessions (34% vs. 18%, p = .01), whereas girls were more likely to endorse hoarding compulsions (53% vs. 36%, p=.009). High scores on the hoarding dimension were associated with increased levels of pervasive slowness, responsibility, indecisiveness, pathological doubt, depression and a variety of emotional difficulties, both self-rated and parent-rated.
The structure of OCD symptoms is similar across the lifespan. Hoarding symptoms are prevalent in pediatric OCD, especially among girls, and are associated with greater levels of disability.
尚不清楚成人中所见的强迫症（OCD）症状结构在儿科样本中是否保留。
对总共238名转诊至专业儿科强迫症诊所的儿童和青少年进行儿童耶鲁-布朗强迫症量表症状清单评估，并对其13个主要症状类别进行探索性主成分分析。将所得因素与相关临床变量进行关联。
主成分分析确定了四个症状维度，解释了总方差的55%，并大致与成人样本中所见的维度相对应。男孩更有可能出现性强迫观念（34%对18%，p = 0.01），而女孩更有可能认可囤积强迫行为（53%对36%，p = 0.009）。囤积维度的高分与普遍的迟缓、责任感、犹豫不决、病理性怀疑、抑郁以及各种自我评定和家长评定的情绪困难水平增加相关。
强迫症症状结构在整个生命周期中相似。囤积症状在儿科强迫症中很普遍，尤其是在女孩中，并且与更高水平的残疾相关。
