Effective behavioral diabetes interventions for Mexican Americans are needed. Our study focused on efforts to recruit Mexican American adults for a trial testing a diabetes community health worker (CHW) self-management intervention.
Behavioral randomized controlled trial, community-based participatory research approach.
Chicago.
Mexican American adults with type 2 diabetes.
Screening and randomization.
Initial eligibility criteria included Mexican heritage, treatment with oral diabetes medication, residence in designated zip codes, planned residence in the area for two years, and enrollment in a specific insurance plan.
Recruitment through the insurer resulted in only one randomized participant. Eligibility criteria were relaxed and subsequent efforts included bilingual advertisements, presentations at churches and community events, postings in clinics, partnerships with community providers, and CHW outreach. Zip codes were expanded multiple times and insurance criteria removed. CHW outreach resulted in 53% of randomized participants.
Despite strong ties with the target community, culturally appropriate recruitment strategies involving community representation, and a large pool of potential participants, significant challenges were encountered in recruitment for this diabetes intervention trial. Researchers identified three key barriers to participation: study intensity and duration, lack of financial incentives, and challenges in establishing trust. For future research to be successful, investigators need to recognize these barriers, offer adequate incentives to compensate for intervention intensity, and establish strong trust through community partnerships and the incorporation of community members in the recruitment process.
需要针对墨西哥裔美国人实施有效的行为学糖尿病干预措施。我们的研究重点是努力招募墨西哥裔美国成年人参与一项试验，以测试针对糖尿病社区卫生工作者（CHW）自我管理干预措施的试验。
行为学随机对照试验，社区参与式研究方法。
芝加哥。
患有 2 型糖尿病的墨西哥裔美国成年人。
筛查和随机分组。
最初的入选标准包括墨西哥裔血统、使用口服糖尿病药物治疗、居住在指定的邮政编码区域、计划在该地区居住两年以及参加特定的保险计划。
通过保险公司进行的招募仅导致一名随机参与者入选。放宽了入选标准，随后的努力包括双语广告、在教堂和社区活动中的演讲、在诊所张贴广告、与社区提供者建立伙伴关系以及 CHW 外展。邮政编码区域多次扩大，取消了保险标准。CHW 外展导致 53%的随机参与者。
尽管与目标社区有着紧密的联系、采用了涉及社区代表的文化适宜性招募策略以及拥有大量潜在参与者，但在这项糖尿病干预试验的招募过程中仍遇到了重大挑战。研究人员确定了参与研究的三个主要障碍：研究强度和持续时间、缺乏经济激励以及建立信任方面的挑战。为了未来的研究取得成功，研究人员需要认识到这些障碍，提供足够的激励措施来补偿干预的强度，并通过社区伙伴关系和在招募过程中纳入社区成员来建立强大的信任。
