背景资料：行为改变在改善健康方面的重要性体现在供资机构增加投资，以制定和评估复杂的干预措施，改变人口、患者和从业者的行为。由于没有一个专门术语来具体说明和报告干预措施的内容，因此阻碍了制定有效的干预措施。这限制了复制有效干预措施、综合证据和理解行为变化背后的因果机制的可能性。相比之下，生物医学干预措施是精确指定的（例如，处方药物的药理“成分”、剂量和给药频率）。对于大多数复杂的干预措施，确切的“成分”是未知的;描述（例如，“行为咨询”）对不同的研究人员或实施者可能意味着不同的东西。缺乏一种方法来指定复杂的干预措施破坏了证据合成的有效性的精度，提出了一个问题，为次要的，以及主要的，research.We的目标是制定一个可靠的方法，指定干预组件（“技术”），旨在改变behavior.Methods/Design：研究将分三个阶段进行。第一阶段将制定命名法。我们将完善一个技术和定义的初步清单。使用正式的共识方法，专家们将定义每种技术的关键属性，以及它与其他技术的关系和区别。他们将评估这些技术及其定义，直到他们获得一个商定的明确定义的非冗余技术列表。第二阶段将测试命名法。受过培训的专家（主要研究人员和系统评审员）配备了编码手册和指南，将使用命名法对已发表的复杂干预措施的描述进行编码。专家之间的可靠性，随着时间的推移，跨类型的用户将进行评估。我们将评估是否使用的术语来写干预措施的描述提高了干预措施的清晰度和可复制性。第三阶段将开发一个基于网络的用户资源，提供明确规定的非冗余技术，这将有助于科学地理解和制定有效的复杂干预措施。整个项目的传播将通过利益相关者会议，有针对性的多学科研讨会，会议介绍，期刊出版物，并在一个互动的基于网络的平台（维基）的出版物。讨论：制定一个可靠的方法，指定干预组件，旨在改变行为将加强科学基础的发展，评估和报告复杂的干预措施。它将提高有效性证据综合的准确性，从而加强二级和初级研究。
Background: The importance of behaviour change in improving health is illustrated by the increasing investment by funding bodies in the development and evaluation of complex interventions to change population, patient, and practitioner behaviours. The development of effective interventions is hampered by the absence of a nomenclature to specify and report their content. This limits the possibility of replicating effective interventions, synthesising evidence, and understanding the causal mechanisms underlying behaviour change. In contrast, biomedical interventions are precisely specified (e.g., the pharmacological 'ingredients' of prescribed drugs, their dose and frequency of administration). For most complex interventions, the precise 'ingredients' are unknown; descriptions (e.g., 'behavioural counseling') can mean different things to different researchers or implementers. The lack of a method for specifying complex interventions undermines the precision of evidence syntheses of effectiveness, posing a problem for secondary, as well as primary, research.We aim to develop a reliable method of specifying intervention components ('techniques') aimed at changing behaviour.Methods/Design: The research will be conducted in three phases. The first phase will develop the nomenclature. We will refine a preliminary list of techniques and definitions. Using a formal consensus method, experts will then define the key attributes of each technique and how it relates to, and differs from, others. They will evaluate the techniques and their definitions until they achieve an agreed-upon list of clearly defined, nonredundant techniques. The second phase will test the nomenclature. Trained experts (primary researchers and systematic reviewers), equipped with a coding manual and guidance, will use the nomenclature to code published descriptions of complex interventions. Reliability between experts, over time, and across types of users will be assessed. We will assess whether using the nomenclature to write intervention descriptions enhances the clarity and replicability of interventions. The third phase will develop a web-based users' resource of clearly specified and nonredundant techniques, which will aid the scientific understanding of, and development of, effective complex interventions. Dissemination throughout the project will be through stakeholder meetings, targeted multidisciplinary workshops, conference presentation, journal publication, and publication in an interactive web-based platform (a Wiki).Discussion: The development of a reliable method of specifying intervention components aimed at changing behaviour will strengthen the scientific basis for developing, evaluating, and reporting complex interventions. It will improve the precision of evidence syntheses of effectiveness, thus enhancing secondary, as well as primary, research.
