Abstract：
Self-report questionnaires are commonly used in depression research with little consideration of their reading ease. This study aimed to increase the reading ease of the commonly-used Quick Inventory of Depressive Symptoms Self Report (QIDS-SR) and assess the impact of the change in wording on the measure\'s psychometric properties. The study had three phases: 1) Flesh-Kincaid readability statistics of the original and modified wording were compared; 2) a sample of n = 95 participants rated the modified wording for perceived change in meaning and ease of understanding; 3) a second sample of n = 136 participants completed two versions of the QIDS-SR (original, modified, or one of each) alongside the Beck Depression Inventory (BDI). The internal consistency, test-retest reliability and convergent validity of the modified version were assessed. The modified QIDS-SR had significantly higher reading ease, was considered easier to understand and was not perceived to have a significant change in meaning. Its psychometric properties were unaffected. The wording of the questionnaire was successfully simplified to increase its accessibility and this had no notable impact on the psychometric properties of the measure.
摘要：
自我报告问卷通常用于抑郁症研究，很少考虑其阅读难易程度。这项研究旨在提高常用的抑郁症状快速清单自我报告（QIDS-SR）的阅读便利性，并评估措辞变化对该措施的心理测量特性的影响。该研究分为三个阶段：1）比较原始和修改后的措辞的Flesh-Kincaid可读性统计数据；2）n=95名参与者的样本对修改后的措辞进行了含义变化和易于理解的评价；3）n=136名参与者的第二个样本完成了QIDS-SR的两个版本（原始，已修改,或每个中的一个)与贝克抑郁量表(BDI)一起。内部一致性,评估了修订版的重测信度和收敛效度。修改后的QIDS-SR具有明显更高的阅读易用性，被认为更容易理解，并且没有被认为在含义上有重大变化。其心理测量特性未受影响。问卷的措辞已成功简化，以增加其可及性，这对该措施的心理测量特性没有显着影响。
