Despite extensive research on physical activity behaviour (PAB), consensus is lacking on related terms and definitions, thereby hindering the ability to compare findings between studies and to develop reliable assessment tools. This study therefore aimed to establish consensus on the definitions of key PAB determinants.
First, an international expert steering committee was established, comprising members of the European Cooperation in Science and Technology (COST) action "DEterminants of Physical ActivitieS in Settings" (DE-PASS). Recently published review-level studies were used to identify key determinants of PAB. Two independent reviewers systematically reviewed the literature to catalogue the range of definitions used for key determinants of PAB (steps 1-2). A two-round modified Delphi survey was conducted online from February to September 2023, to determine the optimal definition for each determinant. In round 1, experts selected the most suitable definition for each of the 41 initially identified determinants. In round 2, experts ranked the appropriateness of the definition selected from round 1 on a 5-point Likert scale. Consensus was defined a priori as ≥ 75% agreement on the definition (i.e., ratings of ≥ 4 points). A professional English language expert ensured concise, coherent wording and high-quality editing of the definitions (steps 3-6).
Eighty-five experts in PAB research participated in round 1, and sixty-nine experts in round 2. Consensus of definitions was achieved for 39 of the 41 determinants (88.4%-98.6% agreement). The consensus threshold was not achieved for two determinants: genetic profile and regulation (69.6%) and backyard access/size (73.9%).
The findings of this study offer a consensus-based set of definitions for 39 key determinants of PAB. These definitions can be used homogenously in academic research on physical activity.
尽管对身体活动行为（PAB）进行了广泛研究，但在相关术语和定义上仍缺乏共识，这阻碍了研究之间比较结果以及开发可靠评估工具的能力。因此，本研究旨在就关键PAB决定因素的定义达成共识。
首先，成立了一个国际专家指导委员会，成员包括欧洲科技合作组织（COST）“环境中身体活动的决定因素”（DE-PASS）行动的成员。利用最近发表的综述级研究来确定PAB的关键决定因素。两名独立评审员系统地回顾文献，以编目用于PAB关键决定因素的定义范围（步骤1-2）。2023年2月至9月进行了两轮在线改良德尔菲调查，以确定每个决定因素的最佳定义。在第一轮中，专家们为最初确定且经筛选的41个决定因素中的每一个选择最合适的定义。在第二轮中，专家们根据5点李克特量表对第一轮中选择的定义的适当性进行排名。事先将共识定义为对定义的≥75%的一致意见（即评分≥4分）。一位专业英语专家确保定义的措辞简洁、连贯，并进行高质量编辑（步骤3-6）。
85名PAB研究专家参与了第一轮，69名专家参与了第二轮。41个决定因素中的39个（88.4%-98.6%的一致意见）达成了定义共识。两个决定因素未达到共识阈值：基因特征和调控（69.6%）以及后院通道/面积（73.9%）。
本研究结果为39个PAB关键决定因素提供了一套基于共识的定义。这些定义可在身体活动的学术研究中统一使用。
