Arts therapies draw upon many theories and models of practice, but lack consensus in shared factors of their provision. In preparation for a randomised controlled trial involving art therapy, dance movement therapy and music therapy, we used experiential and practice-based methods to develop a model and manual for mixed diagnosis arts therapies groups in community mental health care. Six arts therapists met over the course of a year to explore commonalities and differences in art, dance movement and music therapy groups. Arts-based and consensus methods were used to develop practice principles, which were expanded through workshops with arts therapists working in mental health services. A model, manual, training and adherence guide were produced, which incorporated role-play and video-based reflection. The model is underpinned by transdiagnostic and contextual psychotherapy theories. The manual outlines ten core principles, alongside 19 practice principles. Fourteen scenarios where therapists commonly intervene informed ongoing therapist training and development. This is the first model to describe practice across three types of arts therapies for mixed diagnosis groups in community mental health care. Whilst overall manual utility (including adherence) and effectiveness is yet to be assessed, the development methods may be informative for wider arts therapies groups and clientele.

艺术疗法借鉴了许多理论和实践模型，但在其提供的共同因素上缺乏共识。在准备涉及艺术疗法，舞蹈动作疗法和音乐疗法的随机对照试验的过程中，我们使用了基于经验和实践的方法，为社区精神卫生保健中的混合诊断艺术疗法组开发了模型和手册。一年中有六名艺术治疗师会面，探讨艺术，舞蹈动作和音乐治疗组的共同点和差异。使用基于艺术和共识的方法来制定实践原则，并通过与从事精神卫生服务的艺术治疗师的研讨会进行了扩展。制作了模型，手册，培训和遵守指南，其中包括角色扮演和基于视频的反思。该模型以跨诊断和情境心理治疗理论为基础。该手册概述了十项核心原则以及19种实践原则。治疗师通常进行干预的十四种情况为正在进行的治疗师培训和发展提供了信息。这是第一个描述针对社区精神卫生保健中的混合诊断人群的三种艺术疗法的实践的模型。虽然总体的手动效用（包括依从性）和有效性尚待评估，但开发方法可能对更广泛的艺术疗法团体和客户具有参考价值。这是第一个描述针对社区精神卫生保健中的混合诊断人群的三种艺术疗法的实践的模型。虽然总体的手动效用（包括依从性）和有效性尚待评估，但开发方法可能对更广泛的艺术疗法团体和客户具有参考价值。这是第一个描述针对社区精神卫生保健中的混合诊断人群的三种艺术疗法的实践的模型。虽然总体的手动效用（包括依从性）和有效性尚待评估，但开发方法可能对更广泛的艺术疗法团体和客户具有参考价值。
