背景。本研究的目的是检验日本人群中积极影响项目的测量特性。我们比较了85名日本精神科门诊患者对日本流行病学研究中心抑郁量表的反应，以及对原积极情绪项目的四个附加负面修订项目的反应，这些患者有焦虑情绪相关症状，255名人口统计学上匹配的对照组。两组对积极情绪项目的反应大体上具有可比性，而对消极症状项目的反应则有显著差异（P < 0.002）。组间差异以症状持续性最为显著。对正面影响的四个负面修正项目的反应与负面症状项目的反应相似。当原积极情绪条目被负向修正条目取代后，量表的内部一致性显著提高（P < 0.001）。具有积极措辞的积极影响条目不能充分地用于评估日本人群的抑郁症，但可以用相应的消极修订条目来评估。
Background. The purpose of the present study was to examine the measurement properties of positive affect items among the Japanese population.Methods. Responses to the Japanese version of the Center for Epidemiologic Studies Depression Scale and four additional negatively revised items of the original positive affect items were compared for 85 Japanese psychiatric out-patients with dysphoric-mood-related symptoms and 255 demographically matched controls.Results. Responses to positive affect items were generally comparable between the two groups, whereas responses to negative symptom items were markedly different (P < 0.002 for all comparisons). The group difference was most marked for symptom persistence. Responses to the four negatively revised items of positive affect revealed a similar picture to that of the negative symptom items. The internal consistency of the scale significantly improved when the original positive affect items were replaced by the negatively revised items (P < 0.001 for both).Conclusions. Positive affect items with positive wording cannot be used to assess depressive disorders in the Japanese population adequately, but this can be done with the corresponding negatively revised items.
