Developing a Taxonomy of Dyadic Behavior Change Techniques

越来越多的文献证明了社会背景在塑造健康行为变化中的重要性。为了更好地理解亲密关系，特别是恋爱关系对健康的保护作用，研究人员已经提出了大量的理论和实证结果。然而，尽管进行了几十年的研究，但浪漫关系对健康产生强大影响的具体过程仍远未被了解。这一广泛的研究领域，包括心理学内外的学科，已经产生了高度不同的命名法和无数不同复杂性的概念，阻碍了经验证据的合成。与此同时，二元干预研究有所增加，其中许多研究涉及恋爱伙伴以改变健康行为。总体而言，到目前为止的证据表明，对浪漫夫妇进行双向干预是一条很有希望的途径。然而，由于缺乏对干预内容的报告和对干预策略的不系统标记，人们对这些干预措施取得成功的确切原因知之甚少。系统地识别和分类促进行为改变的干预技术的现有分类主要集中在个体水平上的技术(例如，目标设定、自我监控)。涉及与非专业二元成员任何形式的互动的干预技术(即二元行为改变技术)没有得到很好的体现或很好地区分。因此，为了理解健康行为改变中的二元过程，系统而可靠地识别二元行为改变技术是下一步重要的一步。牵头机构拟议的项目“开发二元行为改变技术的分类”旨在开发和评估基于理论的独特、清晰和精确的二元行为改变技术(DBCT)的全面和可靠的分类，以促进促进健康(例如，体力活动、营养)或损害健康(例如，吸烟、饮酒)行为的改变。我们将以浪漫夫妇为例，将其作为健康行为改变的一个非常重要的二元体。通过利用国际专家网络，我们的目标是建立一个国际公认的分类法，确保准确报告二元干预内容，指导基于理论的二元行为改变干预措施的发展，并促进关于浪漫夫妇有效二元行为改变的跨学科证据合成。这将为建立其他二元星座(例如，父母-孩子、同伴)或上下文(例如，心理健康、压力)的未来DBCT分类奠定坚实的基础。

A growing literature documents the importance of the social context in shaping health behavior change. Researchers have produced a large number of theories and empirical findings to better understand the protective effect of close relationships, in particular the romantic relationship, on health. However, despite decades of research, the specific processes underlying the powerful effect of romantic relationships on health are still far from understood. This broad research field, including disciplines within psychology as well as beyond, has produced a highly heterogeneous nomenclature and a myriad of constructs of different complexity, hampering the synthesis of empirical evidence. At the same time, there has been a rise in dyadic intervention studies, many of which involve romantic partners to change health behavior. Overall, evidence to date suggests that dyadic interventions in romantic couples are a promising avenue. However, due to poor reporting of intervention content and unsystematic labelling of intervention strategies, little is known about what exactly makes these interventions successful. Existing taxonomies that systematically identify and classify intervention techniques to promote behavior change have mainly focused on techniques at the level of the individual (e.g., goal setting, self-monitoring). Intervention techniques involving any form of interaction with a non-professional dyad member (i.e. dyadic behavior change techniques) are underrepresented or not well differentiated. Thus, to understand dyadic processes in health behavior change, a systematic and reliable identification of dyadic behavior change techniques is an important next step. The proposed Lead Agency project “Developing a Taxonomy of Dyadic Behavior Change Techniques” aims to develop and evaluate a comprehensive and reliable taxonomy of theory-based distinct, clear, and precise dyadic behavior change techniques (DBCTs) for facilitating change in health-enhancing (e.g., physical activity, nutrition) or health-compromising (e.g., smoking, alcohol consumption) behaviors. We will use the example of the romantic couple as a highly important dyad for health behavior change. By drawing on a network of international experts, we aim to establish an internationally accepted taxonomy that will ensure precise reporting of dyadic intervention content, guide the development of theory-based dyadic behavior change interventions, and facilitate evidence synthesis across disciplines on effective dyadic behavior change in romantic couples. This will lay a solid foundation for establishing future DBCT taxonomies for other dyad constellations (e.g., parent-child, peers) or contexts (e.g., mental health, stress).
