  Objective. Organizational changes, such as program management and managed care, and fluctuations in resources present challenges to the effective provision of fieldwork placements. This study compared an innovative group model with a traditional 1:1 supervision model to determine their effect on students and supervisors.

  Method: The two models were implemented at an urban clinical facility in several areas of practice over a 2 year period. Questionnaires were used to assess student skill development, student and supervising therapist satisfaction, and impact on supervising therapists' use of time. Focus groups were used to explore the advantages and disadvantages of each model.

  Results. There were few statistically significant differences in students' (n=26) and supervising therapists' (n=28) ratings when the two models were compared. The qualitative findings suggest that the advantages of one model often relate to the disadvantages of the other model. In addition, supervising therapists and students offered several suggestions for how to improve implementation of the group model.

  Conclusion: When the results of the study are compared to the objectives established for the group model, it appears that many of the objectives outlined for the model were partially achieved. Several issues, such as the student-supervisor relationship and the evaluation process, need to be addressed with participants to ensure successful implementation of the group model.

  目的。组织变革，如项目管理和管理护理，以及资源波动，给有效提供实习场所带来挑战。本研究比较了一种创新的小组模型和传统的1:1监督模型，以确定它们对学生和督导的影响。 方法：在城市临床设施中，针对多个实践领域，实施了这两个模型，历时2年。使用问卷评估了学生技能发展、学生和督导治疗师的满意度以及对督导治疗师时间利用的影响。使用焦点小组探讨了每种模型的优缺点。 结果。当比较这两种模型时，学生（n=26）和督导治疗师（n=28）的评分差异很小。定性发现表明，一种模型的优点通常与另一种模型的缺点相关。此外，督导治疗师和学生提出了几条建议，以改善小组模型的实施。 结论：当将研究结果与小组模型设定的目标进行比较时，似乎该模型的许多目标部分实现。需要与参与者解决一些问题，例如学生-督导关系和评估过程，以确保成功实施小组模型。
