A previous two-factor solution of the AMP system was confirmed by a factor analysis in 552 patients, mainly suffering from endogenous psychoses. Based on these results, two second-order scales ('manic-depressive' and 'schizophrenic syndrome') were constructed according to the classical theory of mental testing. The scales are orthogonal. Their reliability and validity is satisfactory. It is suggested to use the two new scales together with the known 9 AMP scales.
AMP系统先前的双因素解决方案在552名主要患有内源性精神病的患者中通过因素分析得到了证实。基于这些结果，根据经典心理测试理论构建了两个二阶量表（“躁郁症”和“精神分裂症综合征”）。这些量表是正交的。它们的信度和效度令人满意。建议将这两个新量表与已知的9个AMP量表一起使用。
