Computer-based virtual coaches are increasingly being explored for patient education, counseling, and health behavior training and coaching. The objective of this research was to develop and evaluate a Virtual Mindfulness Coach for training and coaching in mindfulness meditation.
The coach was implemented as an embodied conversational character, providing mindfulness training and coaching via mixed initiative, text-based, natural language dialog with the student, and emphasizing affect-adaptive interaction. (The term 'mixed initiative dialog' refers to a human-machine dialog where either can initiate a conversation or a change in the conversation topic.)
Findings from a pilot evaluation study indicate that the coach-based training is more effective in helping students establish a regular practice than self-administered training using written and audio materials. The coached group also appeared to be in more advanced stages of change in terms of the transtheoretical model, and have a higher sense of self-efficacy regarding establishment of a regular mindfulness practice.
These results suggest that virtual coach-based training of mindfulness is both feasible, and potentially more effective, than a self-administered program. Of particular interest is the identification of the specific coach features that contribute to its effectiveness.
Virtual coaches could provide easily accessible and cost-effective customized training for a range of health behaviors. The affect-adaptive aspect of these coaches is particularly relevant for helping patients establish long-term behavior changes.
基于计算机的虚拟教练越来越多地被用于患者教育、咨询和健康行为培训和指导。本研究的目的是开发和评估一个用于正念冥想培训和指导的虚拟正念教练。
教练被实现为一个体现式对话角色,通过与学生进行混合主动、基于文本的自然语言对话,提供正念训练和指导,并强调情感自适应交互。(术语“混合主动对话”是指人机对话,其中任何一方都可以发起对话或改变对话主题。)
一项试点评估研究的结果表明,基于教练的培训比使用书面和音频材料的自我管理培训更有效地帮助学生建立定期练习。就跨理论模型而言,接受教练培训的小组似乎处于更高级的改变阶段,并且在建立定期正念练习方面自我效能感更高。
这些结果表明,基于虚拟教练的正念培训比自我管理计划更可行且更有效。特别有趣的是确定了对其有效性有贡献的具体教练功能。
虚拟教练可以为各种健康行为提供易于获得且具有成本效益的定制培训。这些教练的情感自适应方面对于帮助患者建立长期行为改变特别相关。
