This study was part of a process evaluation for a single-blind, randomized controlled pilot study comparing Better Conversations with Primary Progressive Aphasia (BCPPA), an approach to communication partner training, with no speech and language therapy treatment. It was necessary to explore fidelity of delivery (delivery of intervention components) and intervention enactment (participants' use of intervention skills in the form of conversation behaviours comprising facilitators, that enhance the conversational flow, and barriers, that impeded the flow of conversation). This study aimed to: (1) Outline an adapted methodological process that uses video observation, to measure both fidelity of delivery and enactment. (2) Measure the extent to which the BCPPA pilot study was delivered as planned, and enacted.

制定沟通障碍干预措施的保真度和实施措施

这项研究是一项单盲、随机对照试点研究过程评估的一部分，该研究将“更好的对话”与原发性进行性失语症 (BCPPA) 进行比较，BCPPA 是一种沟通伙伴培训方法，无需言语和语言治疗。有必要探索交付的保真度（干预成分的交付）和干预实施（参与者以对话行为的形式使用干预技能，其中包括促进对话流程的促进者和阻碍对话流程的障碍）。本研究的目的是：（1）概述使用视频观察的改编方法过程，以衡量交付和表演的保真度。(2) 衡量 BCPPA 试点研究按计划交付和实施的程度。
