目的探讨不参加以初级保健为基础的体力活动试验的原因，并了解这些原因如何有助于招募不具代表性的研究样本。我们还旨在引出非参与者自己的建议，以加强初级保健中的试验吸收。设计对非参与者的半结构化电话访谈，对非参与者进行随机对照试验，以促进初级保健中的体力活动(非常简短的干预试验)，并对访谈记录进行主题分析。在英国英格兰东部设置5个全科医生(GP)手术。参与者访谈包括10名女性和6名男性，年龄在40岁到71岁之间。根据全科医生体力活动问卷(GPPAQ)，16名受访者中有13名为活跃或中度活跃。这些包括基于对干预内容的先入为主的看法，围绕试验的个人相关性。许多受访者认为自己要么足够活跃，要么功能太有限，无法进一步提高活动水平，因此在他们看来，参与是没有意义的。其他已确定的障碍包括缺乏自由时间参与试验和增加体力活动，以及对全科医生手术预约安排制度的不满。受访者质疑初级保健作为提供促进体力活动干预措施的背景是否适当。总体而言，受访者对参与试验的想法持积极态度，特别是在个人利益突出的情况下，但建议可以在不同的环境中提供干预措施，如互联网。结论需要重新考虑在初级保健中进行的促进体力活动试验的参与度、邀请材料的内容和联系潜在参与者的程序。具体建议包括简化干预材料并加强其与受邀者健康问题的相关性。试验注册号ISRCTN72691150；预结果。
Objectives To explore reasons for non-participation in a primary care-based physical activity trial and understand how these may contribute to recruitment of non-representative research samples. We also aimed to elicit non-participants' own recommendations for enhancing trial uptake in primary care.Design Semistructured telephone interviews with non-participants to a randomised controlled trial of a very brief intervention for promoting physical activity conducted in primary care (the Very Brief Interventions trial), with thematic analysis of interview transcripts.Setting 5 general practice (GP) surgeries in the East of England, UK.Participants Interviews were completed with 10 female and 6 male non-participants of white ethnicity and aged between 40 and 71years. 13 of the 16 interviewees were either active or moderately active according to the GP Physical Activity Questionnaire (GPPAQ).Results Interviewees discussed a range of reasons for non-participation. These included beliefs surrounding the personal relevance of the trial based on preconceptions of intervention content. Many interviewees considered themselves either sufficiently active or too functionally limited to increase activity levels further, so rendering participation pointless in their view. Other identified barriers included a lack of free time, for trial participation and for increasing physical activity, and dissatisfaction with appointment scheduling systems in place at GP surgeries. Interviewees questioned the appropriateness of primary care as a context for delivering interventions to promote physical activity. In general, interviewees were positively disposed towards the idea of trial participation, especially if personal benefits are made salient, but suggested that interventions could be delivered in a different setting such as the internet.Conclusions To increase participation in physical activity promotion trials conducted in primary care, the content of invitation materials and procedures for contacting potential participants require reconsideration. Specific recommendations include streamlining intervention materials and enhancing their relevance to the health concerns of invitees.Trial registration number ISRCTN72691150; Pre-results.
