Group decision-making can be placed on a continuum of group dynamics, between Groupthink and Polythink.
To present a new assessment tool for the characterization of medical teams' decision-making group dynamics, and test it to study the effects of exposure to rudeness on various types of group dynamics.
Three judges who watched videotapes of critical care simulations evaluated 24 neonatal intensive care unit teams' decision-making processes. Teams were rated using the new assessment tool, especially designed for this quantitative study, based on items adapted from symptoms of Polythink and Groupthink.
Measures of reliability, inter-rater agreement and internal consistency, were reasonably good. Confirmatory factor analysis refined the tool and verified that the symptoms in each category (Polythink or Groupthink) of the refined 14 items' assessment tool were indeed measures of the construct. The average General Score was in the range of the balanced dynamic on the continuum, and without tendency towards one of the extremities (Groupthink or Polythink). No significant effect of exposure to rudeness on group dynamics was found.
This is a first attempt at using quantitative methods to evaluate decision-making group dynamics in medicine, by adapting symptoms of Groupthink and Polythink as items in a structured assessment tool. It suggests a new approach to understanding decision-making processes of medical teams. The assessment tool seems to be a promising, feasible and reasonably reliable research tool to be further studied in medicine and other disciplines engaged in decision-making.
群体决策可以置于群体思维和多元思维之间的群体动态连续统一体上。
提出一种用于表征医疗团队决策群体动态的新评估工具，并对其进行测试，以研究接触无礼行为对各类群体动态的影响。
三名观看重症监护模拟录像带的评判员对24个新生儿重症监护病房团队的决策过程进行评估。根据专门为此定量研究设计的新评估工具，基于从多元思维和群体思维症状改编而来的项目对团队进行评分。
信度、评分者间一致性和内部一致性的测量结果相当不错。验证性因素分析完善了该工具，并证实了经过完善的14项评估工具中每个类别（多元思维或群体思维）的症状确实是该结构的测量指标。总体平均得分处于连续统一体上平衡动态的范围内，且没有偏向任何一个极端（群体思维或多元思维）。未发现接触无礼行为对群体动态有显著影响。
这是首次尝试通过将群体思维和多元思维的症状改编为结构化评估工具中的项目，使用定量方法评估医学中的决策群体动态。它提出了一种理解医疗团队决策过程的新方法。该评估工具似乎是一种有前景、可行且相当可靠的研究工具，有待在医学和其他从事决策的学科中进一步研究。
