This paper contrasts the usual scoring of the GHQ-30 with scoring based upon a criterion approach applied to only 12 of the GHQ items that takes account of the 'diagnostic significance' of the chosen items. Repeat assessments with this shorter form of the questionnaire (the I-GHQ), coupled with procedures to assess change, can be used to provide summary measures of symptom course in those research situations where available interview time precludes the use of more formal assessment methods.
本文将一般健康问卷-30（GHQ-30）的常规计分与基于标准方法的计分进行了对比，该标准方法仅应用于GHQ的12个项目，并考虑了所选项目的“诊断意义”。使用该问卷的较短形式（I-GHQ）进行重复评估，并结合评估变化的程序，可用于在可用于访谈的时间不允许使用更正式评估方法的研究情况下，提供症状病程的汇总测量。
