The scaling problem of measurement of clinical data in psychiatry should be differed from, although connected with, the statistical problem of statistical significance testing in psychopharmacological trials. The scaling levels (ordinal versus interval) of a rating scale as well as the statistical tests (non-parametric versus parametric) are different in Phase II and Phase III trials. Sufficient statistics of improvement curves and of recovery rates are discussed.
精神病学临床数据测量的量表问题，尽管与精神药理学试验中统计显著性检验的统计学问题相关，但仍应与之区分开来。在II期和III期试验中，评定量表的量表水平（顺序量表与等距量表）以及统计检验（非参数检验与参数检验）有所不同。文中还讨论了改善曲线和恢复率的充分统计量。
