高保留率和治疗依从性是确保临床试验证据质量的关键。已经探索了改善这些问题的策略，但生活方式干预试验的实际比率表明存在挑战。这项研究在成人哮喘控制的健康饮食模式干预试验中，研究了在获得知情同意、收集基线数据和随机化之前的互动小组定向中，动机访谈-知情策略的使用。由小组讨论产生并在迎新会议期间的大小组讨论中得到回应的主题有助于潜在参与者更好地理解研究设计和程序的科学理由以及对他们参与研究的实际影响。潜在参与者报告说，在小组培训后，完成研究的信心显著降低。这表明，团体定向有助于潜在参与者确定完成研究的挑战，对参与有更现实的期望，并为入选做好准备。保留率(6个月时90名参与者中的92%)和干预出席率(46名干预参与者中的99%参加了每周11次小组/个人会议中的80%)都很高，这表明动机访谈-知情小组定向策略可能有助于提高临床试验中的保留率和依从性。
High retention and treatment adherence are essential to ensure the quality of evidence from clinical trials. Strategies for improving these have been explored but actual rates in lifestyle intervention trials indicate challenges. This study examined the use of a motivational interviewing-informed strategy during interactive group orientations prior to obtaining informed consent, collecting baseline data and randomization in a healthy dietary pattern intervention trial for asthma control in adults. The themes generated from small group discussions and echoed in large group discussions during the orientation sessions helped potential participants better understand the scientific rationale of the research design and procedures and the practical implications for them to participate in the study. Potential participants reported significantly lower confidence of completing the study after the group orientation. This suggests that the group orientations helped potential participants identify challenges to completing the study, have more realistic expectations about participation and be prepared if enrolled. Both retention (92% of 90 participants at 6 months) and intervention attendance (99% of 46 intervention participants attended 80% of 11 weekly group/individual sessions) were high, suggesting the motivation interviewing-informed group orientation strategy may help improve retention and adherence in clinical trials.
