BACKGROUND Research contributions by registered dietitian nutritionists (RDNs) are important for enhancing the use of nutrition-related evidence-based guidelines in dietetics practice. Involvement of RDNs in research activities has been studied previously, but little is known about the drivers (motivators) of sustaining research involvement by RDNs who work in clinical practice. OBJECTIVE To identify key characteristics of established RDN clinician researchers and drivers that contributed to their sustained research involvement. DESIGN We used a convergent parallel mixed methods study design utilizing the clinician career research trajectory as a framework. Research involvement was examined using the Practice-Based Dietitian Research Involvement Survey (PBDRIS). Workplace support was assessed using the Research Capacity and Culture (RCC) survey. Semistructured interviews were used to investigate key themes in established RDN clinician researchers. PARTICIPANTS/SETTING We identified 450 RDNs involved with research activities in the United States through hand-searching clinically relevant nutrition journals and contacted them to participate in an online survey. A total of 29 RDNs met criteria and completed (6.4%) the quantitative survey, then a subsample (n=10) participated in semistructured interviews to explore drivers for continued research involvement. RESULTS Research involvement scores (n=29) from the PBDRIS ranged from 60.0% to 97.5%, indicating involvement in higher-level research-related tasks by our sample participants. RCC results revealed the importance of workplace support and mentorship. Interviews with established RDN clinician researchers identified exposure, curiosity, and dedication as three overarching themes with eight subthemes driving continued research involvement. CONCLUSION Based on the experiences of select RDN clinician researchers who have demonstrated success in sustaining their research involvement, we found that having an available mentor, support from their workplace environment, and personal drive were integral to their success.

注册营养师持续参与临床研究活动的特征和驱动因素：混合方法研究

背景 注册营养师营养师 (RDN) 的研究贡献对于加强营养相关循证指南在营养学实践中的使用非常重要。RDNs 在研究活动中的参与之前已经被研究过，但对于在临床实践中工作的 RDNs 维持研究参与的驱动因素（动机）知之甚少。目标 确定已建立的 RDN 临床医生研究人员和推动他们持续参与研究的关键特征。设计 我们使用了一种以临床医生职业研究轨迹为框架的收敛平行混合方法研究设计。使用基于实践的营养师研究参与调查 (PBDRIS) 检查研究参与。使用研究能力和文化 (RCC) 调查评估工作场所支持。半结构化访谈用于调查已建立的 RDN 临床医生研究人员的关键主题。参与者/设置 我们通过手工搜索临床相关的营养期刊，确定了 450 名参与美国研究活动的 RDN，并联系他们参与在线调查。共有 29 个 RDN 符合标准并完成了 (6.4%) 定量调查，然后一个子样本 (n=10) 参与了半结构化访谈，以探索继续参与研究的驱动因素。结果 PBDRIS 的研究参与分数 (n=29) 范围从 60.0% 到 97.5%，表明我们的样本参与者参与了更高级别的研究相关任务。RCC 结果揭示了工作场所支持和指导的重要性。与成熟的 RDN 临床医生研究人员的访谈确定了暴露、好奇、和奉献作为三个总体主题，八个子主题推动了持续的研究参与。结论 根据在维持他们的研究参与方面取得成功的精选 RDN 临床医生研究人员的经验，我们发现拥有可用的导师、工作环境的支持和个人动力是他们成功不可或缺的一部分。
