Barriers in participant recruitment of diverse ethnicities in the state of Kuwait

Abstract

Background: High rejection rates of subject recruitments for research studies have been reported in immigrants in many countries. However, the barriers in recruiting members of the expatriate population in Kuwait have not yet been investigated. This study was therefore designed to identify barriers in recruiting expatriates for research studies in the state of Kuwait. Methods. A population-based cross-sectional study was conducted on expatriate subject's aged 18 years and older living in Kuwait. Difference between groups of continuous independent variables was analyzed using the t-test. Different categories such as ethnicity and gender were compared using the chi-square test. Results: 3460 (85.1%) participants were recruited and 617 (14.2%) refused to participate in the study while 2530 (38%) calls were unreachable from the total of 6607 calls placed. Younger subjects (mean age 41.1 years) were more hesitant to be part of the study compared to older participants. The rejections among South Asians was (41.8%), Arabs (32.6%), Southeast Asians (18.9%) while the others (6.6%) category was least to refuse among all the nationalities. Gender was not significantly associated with refusal. Conclusion: There is an acute lack of appropriate recording of the problems faced while recruiting the participants. The findings suggest important messages for the decision makers in the area of expatriate recruitments, to understand the challenge and design new strategies to overcome the problem of recruitment in the state of Kuwait for research studies. © 2013 Tariq et al.; licensee BioMed Central Ltd.
