话语连贯反映了听者对说话人所传达的整体意义的理解能力。测量整体连贯性（维持话语的主题统一性）对于量化临床人群话语层面的沟通障碍和衡量对话语层面治疗的反应是有用的。目的：目的是确定作者开发的四点全球相干尺度的可行性。具体来说，他们是：(1)估计四点全球相干量表的测量可靠性；(2)评估四点全球一致性量表的结构效度。方法与程序50名年龄在28 ~ 58岁之间认知健康的成年人参加了这项研究。参与者观看并讲述两本没有文字的绘本中描述的故事。参与者的故事被正字法转录并分割成交流单元（C‐unit）。评分者使用两种全球一致性量表（四分制和五分制）对每个参与者的故事进行全球一致性评分。每个C‐unit获得一个单独的分数，然后计算平均整体连贯性分数，得出每个连贯性量表的两个平均整体连贯性分数，每个故事一个，所有参与者。结果与结果结果显示量表的估计信度较高。此外，建构效度，特别是面孔效度和收敛效度，被有效地估计为使用四点量表作为维持认知健康的成年人讲的故事的整体连贯性的措施。最后，我们发现无字绘本所引出的故事具有可比性，并且可以作为不同的形式可靠地交换，以评估全球连贯性的维持。结论与意义本研究假设本方法可行，并充分评估了量表的面效度和收敛效度。未来的研究应考虑估计测量的预测效度、并发效度和区别效度。
BackgroundDiscourse coherence is a reflection of the listener's ability to interpret the overall meaning conveyed by the speaker. Measuring global coherence (maintenance of thematic unity of the discourse) is useful for quantifying communication impairments at the discourse level in clinical populations and for measuring response to discourse‐level treatments.AimsThe aim was to determine feasibility of a four‐point global coherence scale developed by the authors. Specifically, they were (1) to estimate measurement reliability of the four‐point global coherence scale; and (2) to estimate construct validity for the four‐point global coherence scale.Method & ProceduresFifty cognitively healthy adults aged between 28 and 58 years participated in the study. Participants viewed and then told the stories depicted in two wordless picture books. Participants’ stories were orthographically transcribed and segmented into communication units (C‐unit). Raters scored each participant's story for global coherence using two global coherence scales (four‐ and five‐point scales). Each C‐unit received an individual score, then the mean global coherence score was computed, resulting in two mean global coherence scores for each coherence scale, one for each story, for all participants.Outcomes & ResultsResults indicated high reliability estimates for the scale. In addition, construct validity, specifically face validity and convergent validity, was effectively estimated for using the four‐point scale as a measure of maintenance of global coherence in stories told by cognitively healthy adults. Lastly, it was found that the wordless picture books elicited stories that are comparable and can be reliably interchanged as different forms to evaluate maintenance of global coherence.Conclusions & ImplicationsThe assumptions that the measure is feasible were achieved and face and convergent validity were adequately estimated. Future investigations should consider estimating predictive validity, concurrent validity and discriminant validity of the measure.
