OBJECTIVE
The purpose of the present study was to identify the factor structure of manic symptoms as assessed by the Scale for Manic States (SMS).
METHOD
The pattern of symptoms in a group of 225 adults with an ICD-10-DCR diagnosis of manic episode was studied. A factor analysis was conducted of the broad range of psychiatric symptoms covered by SMS. A principal component analysis followed by oblimin rotation was performed.
RESULTS
Six eigenvalues were greater than unity and parallel analysis indicated four factors. After observing the scree plot a five-factor solution seemed appropriate. Nevertheless, a six-factor solution was chosen that described the data appropriately and was clinically relevant. The six factors (psychosis, irritability aggression, dysphoria, accelerated thought stream, hedonia, and hyperactivity) captured 59.29% of the total variance.
CONCLUSION
A six-factor solution explains the clinical dimensions of mania in the present sample and dysphoria appeared as a separate factor.
目的
本研究旨在确定《躁狂状态量表》（SMS）评估的躁狂症状的因子结构。
方法
对 225 名符合 ICD-10-DCR 诊断标准的躁狂发作成年患者的症状模式进行研究。对 SMS 涵盖的广泛精神症状进行因子分析。采用主成分分析，然后进行 Oblimin 旋转。
结果
有六个特征值大于 1，平行分析表明存在四个因子。观察完陡坡图后，似乎需要五因子解决方案。然而，选择了六因子解决方案，该方案适当地描述了数据，并且具有临床相关性。这六个因子（精神病、易怒攻击性、抑郁、思维加速、快乐和多动）解释了总方差的 59.29%。
结论
六因子解决方案解释了本研究样本中躁狂的临床维度，并且抑郁表现为一个独立的因子。
