Visualizing community networks to recruit South Asian participants for interviews about bowel cancer screening.

BACKGROUND: South Asians make up the largest ethnic minority group in England and Wales. Yet this group is underrepresented in some programmes to promote health, such as cancer screening. A challenge to addressing such health disparities is the difficulty of recruiting South Asian communities to health research. Effective recruitment requires the development of participants' knowledge about research and their trust. Researchers also need to increase their cultural understanding and to think about how they will communicate information despite language barriers. This article describes the use of an organogram, informed by social network analysis, to identify the community contacts likely to encourage participation of South Asian adults (aged 50-75 years) in interviews to identify the facilitators of home bowel cancer screening. METHODS: We developed an organogram which represented the directional relationships between organizations and key informants against the level of recruitment success to visualize where networking engaged participants. Primary data were recruitment records (February 2019-March 2020). RESULTS: The majority of participants were recruited from faith centres. The topic of bowel cancer was a barrier for some, but recruitment was more successful with the advocacy of leaders within the South Asian communities. Visualizing community networks helped the research team to understand where to concentrate time and resources for recruitment. CONCLUSIONS: The organizational chart was easy to maintain and demonstrated useful patterns in recruitment successes. POLICY SUMMARY: An organogram can provide a practical tool to identify the best strategies and community contacts to engage South Asian participants in studies to inform policy on health promotion activities such as cancer screening.

Testing socioeconomic status and family socialization hypotheses of alcohol use in young people: A causal mediation analysis.

INTRODUCTION: The effect of socioeconomic status on adolescent substance abuse may be mediated by family socialization practices. However, traditional mediation analysis using a product or difference method is susceptible to bias when assumptions are not addressed. We aimed to use a potential outcomes framework to assess assumptions of exposure-mediator interaction and of no confounding of the results. METHOD: We revisited a traditional mediation analysis with a multiple mediator causal mediation approach using data from 17,761 Norwegian young people (13-18 years), 51% female. Data were collected through a print questionnaire. Socioeconomic status was operationalized as parental education and employment status (employed or receiving welfare); drinking behavior as the frequency of alcohol consumption and frequency of intoxication in the past year; and socialization practices as general parenting measures, alcohol-related parental permissiveness, and parent drinking behavior. RESULTS: There was no consistent evidence of exposure-mediator interaction. Formal sensitivity analysis of mediator-outcome confounding was not possible in the multiple mediator model, and this analysis supported the hypothesis that socioeconomic status effects on adolescent substance abuse are fully mediated by family socialization practices, with apparently stronger effects in younger age groups observed in plots. CONCLUSION: We found that the effect of socioeconomic status on adolescent substance abuse was fully mediated by family socialization practices. While our analysis provides more rigorous support for causal inferences than past work, we could not completely rule out the possibility of unmeasured confounding.

Lifestage differences in young UK women's reasons for research participation.

Lifecourse epidemiology suggests that preconception is a valuable opportunity for health promotion with young women. Yet young women are less likely than older women to be research participants, limiting evidence about their needs and risks. Marketing data indicate that young adults are not engaged with one advertising strategy because they transition through three life stages: (i) limited independence and focus on own interests, (ii) increased independence and time with peers and (iii) establishing a home and family. The aim of this study was to explore whether these marketing lifestage categories could inform the tailoring of strategies to recruit young women. Three focus groups per lifestage category were conducted (49 women aged 16-34 years). Lifestage category (i) was represented by further education students, category (ii) by women in workplaces and (iii) by mothers. Questions explored participants' lifestyles, identity, reasons for participation in the current study and beliefs about researchers. Three major themes were identified through framework analysis: profiling how young women spend their time; facilitators of participating in research and barriers to participating. Students and women in work valued monetary remuneration whereas mothers preferred social opportunities. Participants' perceived identity influenced whether they felt useful to research. All groups expressed anxiety about participation. Altruism was limited to helping people known to participants. Therefore, the marketing categories did not map exactly to differences in young women's motivations to participate but have highlighted how one recruitment strategy may not engage all. Mass media communication could, instead, increase familiarity and reduce anxiety about participation.

Patterns of response by sociodemographic characteristics and recruitment methods for women in UK population surveys and cohort studies.

Women are an important public health focus, because they are more likely to experience some social determinants of disease, and they influence family health. Little research has explored the sociodemographic representativeness of women in research studies. We examined the representativeness of female respondents across four sociodemographic factors in UK population surveys and cohort studies. Six UK population-based health surveys (from 2009-2013) and eight Medical Research Council cohort studies (from 1991 to 2014) were included. Percentages of women respondents by age, income/occupation, education status, and ethnicity were compared against contemporary population estimates. Women aged <35 years were under-represented. The oldest women were under-represented in four of nine studies. Within income/occupation, at the highest deprivation level, the range was 4 percent under-representation to 43 percent over-representation; at the lowest level, it was 6 percent under-representation to 21 percent over representation. Of nine studies reporting educational level, four under-represented women without school qualifications, and three under-represented women with degrees. One of five studies over-represented non-white groups and under-represented white women (by 9 percent). Response patterns varied by topic and recruitment and data collection methods. Future research should focus upon the methods used to identify, reach, and engage women to improve representativeness in studies addressing health behaviors.

Research recruitment: A marketing framework to improve sample representativeness in health research.

AIMS: This discussion paper proposes a five-part theoretical framework to inform recruitment strategies. The framework is based on a marketing model of consumer decision-making. BACKGROUND: Respondents in surveys are typically healthier than non-respondents, which has an impact on the availability of information about those most in need. Previous research has identified response patterns, provided theories about why people participate in research and evaluated different recruitment strategies. Social marketing has been applied successfully to recruitment and promotes focus on the needs of the participant, but little attention has been paid to the periods before and after participant-researcher contact (during advertising and following completion of studies). We propose a new model which conceptualises participation as a decision involving motivation, perception of information, attitude formation, integration of intention and action and finally evaluation and sharing of experience. DESIGN: Discussion paper. DATA SOURCES: This discussion paper presents a critical review. No literature was excluded on date and the included citations span the years 1981-2017. IMPLICATIONS FOR NURSING: The proposed framework suggests that researchers could engage a broader demographic if they shape research design and advertising to perform functions that participants are seeking to achieve. The framework provides a novel and useful conceptualisation of recruitment which could help to inform public engagement in research design, researcher training and research policy. CONCLUSION: This framework challenges researchers to investigate the goals of the potential participants when designing a study's advertising and procedures.
