Objectives
To explore issues of intervention tailoring for ethnic minorities based on information and experiences shared by researchers affiliated with the Health Maintenance Consortium (HMC).
Methods
A qualitative case study methodology was used with the administration of a survey (n=17 principal investigators) and follow-up telephone interviews. Descriptive and content analyses were conducted, and a synthesis of the findings was developed. Results: A majority of the HMC projects used individual tailoring strategies regardless of the ethnic background of participants. Follow-up interview findings indicated that key considerations in the process of intervention tailoring for minorities included formative research; individually oriented adaptations; and intervention components that were congruent with participants’ demographics, cultural norms, and social context.
Conclusions
Future research should examine the extent to which culturally tailoring long-term maintenance interventions for ethnic minorities is efficacious and should be pursued as an effective methodology to reduce health disparities.
Keywords: cultural, tailoring, ethnic minorities, disparities
There is evidence that the overall health of the US population has improved13 with social and behavioral interventions playing a crucial role in the process.4,5 The Institute of Medicine (IOM) (2006), however, has noted that ethnic minorities experience higher mortality and morbidity rates than do nonminorities. Hispanics and African Americans experience more age-adjusted years of potential life lost before age 75 than do non-Hispanic whites due to stroke, chronic liver disease and cirrhosis, diabetes, and homicide.6,7 Both Hispanics and African Americans have higher rates of obesity and report lower levels of physical activity than those of non-Hispanic whites.68 Asian populations suffer a higher incidence of tuberculosis, certain types of cancer, and Hepatitis B than do non-Hispanic whites.9 Native Americans are more likely to report poorer health outcomes than any other ethnic group.10 In addition, disparities exist in access to health care and are associated with higher mortality rates among ethnic minority groups.1
The increasing diversification of the United States underlines the need to address ethnic health disparities and weigh the significance of using a cultural sensitivity paradigm in the design and dissemination of health interventions targeting minorities. Whereas ethnic minorities currently constitute about one third of the US population, it is expected that by 2050 minorities will become the majority and represent 54% of the national population. It is also estimated that by 2050, the Hispanic population will grow almost 3-fold (from 49 million to 132.8 million); the Asian group will more than double from 14.4 million to 34.4 million; and the African American population will increase almost 43% (to become 56.9 million).11 If ethnic minorities continue to experience health disparities,1,2,610 the estimated population growth of these groups may exacerbate the negative impact of these disparities.
Responding to both the IOM recommendation to eliminate disparities and the NIH mandate for a more systematic inclusion of ethnic minorities in research12,13 to reflect national demographic trends will require, among other public health strategies, the diffusion of effective health interventions that are culturally sensitive to ethnic minorities.
This paper through a case study approach aimed to explore ways in which the Health Maintenance Consortium (HMC) (a collective of 21 NIH-sponsored research projects) addressed issues of cultural tailoring explicitly for ethnic minority participants. We wanted to understand to what extent, and what types of, culturally sensitive strategies were used by the consortium for tailoring maintenance health interventions that were inclusive of ethnic minority participants.
This case study is based on information and experiences shared by researchers who participated in the HMC. Consortium researchers were funded by NIH to conduct studies to test different theoretical models for achieving long-term behavioral change. Intervention outcomes in these studies included lifestyle behaviors associated to chronic disease (ie, eating behaviors, physical activity, cigarette smoking, and alcohol consumption), more risky behaviors (ie, suicide, drug abuse, and HIV-related sexual behaviors), and preventive practices (ie, mammography and mental health screening).
Cultural Sensitivity Paradigm
The cultural sensitivity paradigm guiding the process of intervention tailoring or adaptation for diverse groups in public health and behavioral research has emerged from multiple disciplines, including health communication,14,15 psychology,16 substance abuse prevention,1723 HIV research,24,25 and health care systems.2630 The paradigm is not only consistent with the movements of patient-centered care and the chronic care model,31 but its relevance is also underscored within the health-disparity literature addressing ethnic disparities.2,28,30,32
The concept of cultural sensitivity has been used interchangeably as cultural competence, cultural appropriateness, or cultural consistency. Although there is not a single theoretical framework or a standard definition in reference to the cultural sensitivity paradigm, we defined the concept as “the extent to which ethnic and cultural characteristics, experiences, norms, values, behavioral patterns, and beliefs of a target population, and relevant historical, environmental, and social forces” (p.493) are taken into account in intervention design, implementation, and assessment.33
The application and impact of the cultural sensitivity paradigm has also been investigated. Considerable research supports the notion that addressing the individual needs and sociocultural context of ethnic minorities in behavioral interventions results in statistically significant health-outcome modifications among participants.3439
Despite the emergence of cultural frameworks and the evidence showing that culturally tailored interventions are effective in improving, in the short term, the health status of ethnic minorities,3439 there is paucity of studies examining cultural sensitivity applications in long-term maintenance of behavior change in minority health research. This case study, therefore, was proposed as an instructive exercise to gain insights on culturally sensitive issues as addressed by HMC researchers.
Background of the Health Maintenance Consortium
The case study consortium was established in 2004 with funding from the National Institutes of Health (NIH). The HMC is a collective of 21 behavioral research projects focused on understanding the long-term maintenance of behavior change as well as identifying intervention components for achieving sustainable health promotion and disease prevention. Coordinated by the NIH Office of Behavioral and Social Sciences Research, the HMC comprised NIH administrators, 21 research investigators in the United States, and the HMC Resource Center program staff and advisors.
A qualitative case study methodology was used for the study. The data collection process consisted of 2 phases: a descriptive analysis of data from a survey administered to 17 HMC principal investigators (PIs) and telephone interviews with 4 HMC PIs to follow up on issues of cultural sensitivity specifically related to ethnic minority participants.
Survey
Using a community-based participatory approach, a task force was established as part of the HMC activities to investigate the role that different intervention strategies played in the long-term maintenance of behavior change. The task force comprised 9 HMC members, including HMC PIs, advisors, and staff and NIH administrators. We all participated on a voluntary basis. The goal of the task force was to compile an inventory of interventions for projects affiliated with the HMC and to identify intervention components. Using a consensus process, the task force designed a structured 52-item questionnaire to be administered to HMC PIs conducting studies that tested the effects of long-term interventions. The task force also established the content validity of the questionnaire. The survey instrument was then pilot tested to assure it met the group’s aim and to test its readability and comprehension. The instrument was administered via e-mail to 21 PIs. A total of 17 PIs responded. The survey queried the PIs about the characteristics of their interventions, including topics related to ways in which the intervention was tailored to be culturally sensitive.
For purposes of this case study, we examined data obtained from responses to only 6 close-ended items included in the instrument survey. These 6 items were related to cultural sensitivity (as shown in Table 1). The data were analyzed using descriptive statistics.

Follow-up Interviews
In addition to analyzing the survey data collected by the task force, authors of this paper also conducted telephone interviews with 4 HMC PIs to expand on issues of cultural-tailoring processes applied to ethnic minority groups. The interviews were based on a theme guide (Table 1).
Principal investigators who responded to the survey (n=17) were asked to state via e-mail whether or not they tailored their interventions to make them culturally sensitive for ethnic minority participants. Of the 17 PIs who replied to the e-mail inquiry, 4 responded affirmatively. One of the interviews was related to an intervention not affiliated to HMC, but was nevertheless considered because the PI culturally adapted the HMC-related intervention to an ethnic minority group. A description of the 4 studies is shown in Table 2.

Studies Included in the Interview Data Analysis
After written consent was obtained, interviews with the 4 PIs were conducted by telephone and recorded. All interviews were transcribed verbatim. For Study 2, the PI and a research team member were interviewed, but both interviews were treated as one set of data or transcript. Transcripts were reviewed independently. Then, using a focused coding process in which concepts that emerged throughout the data were identified, transcript findings were combined into larger, overreaching themes.40 This study was approved by the Texas A&M University Institutional Review Board.
Survey instrument data
The descriptive analysis of survey responses revealed that the most frequent tailoring strategy was matching intervention schedules with participants’ availability (76.5%). Another prevailing strategy was delivering the intervention in accessible locations to participants or meeting their transportation needs (64.7%).
Half of the HMC projects tailored the interventions based on formative research. In addition, 8 studies (47%) reported that their interventions were delivered by individuals who were knowledgeable of the cultural views and values of participants (it is worth noting that the descriptive data did not capture details or examples of such cultural views and values; Table 3).
Table 3

Percentage of HMC Projects (n=17) by Intervention Tailoring Strategy
Almost 2 thirds of the HMC studies developed intervention contents that met the literacy level of the target population (Table 3). All interventions were delivered in English, and only one reported having an interpreter in the intervention classes.
All 17 projects included some ethnic minority participants. The average percentage of ethnic minority inclusion was 40.18%, and the range was from 6% to 100%, with only one study having all participants from an ethnic minority group (Figure 1).

Follow-up Interview Data
Three major themes emerged from data obtained through the follow-up interviews: the importance of formative research in cultural tailoring, intervention cultural components, and main lessons learned.
Formative Research
The intervention tailoring process in 3 projects was informed by formative research including literature searches, focus groups, interviews, theatrical testing, and pilot testing:
“You can read the literature, but unfortunately, even the African American community is not homogeneous. So if you were dealing with Caribbean Americans, African Americans, or Africans, people who have lived in the North versus the South, there really are some differences that need to be taken into account. The only way to really get at those nuanced differences is by doing some in depth formative work” (Study 1).
Study 2 began the formative process by searching the literature for “some insights into things that we should consider changing from the parent program [The Mediterranean Lifestyle Program]. There could be some factors unique to Latinas that would make a difference in terms of learning self- management procedures. In that literature we frankly didn’t find anything that was very profound.”
Study 2 also conducted focus groups, but again “we were left with the sense that the overall format in the parent program was feasible for implementation with Latinas. Childcare and transportation were 2 of the areas the participants thought we should be sensitive to because they thought the intervention would be rather demanding.”
Study 1 conducted 2 pilots assessing the feasibility and cultural appropriateness of the program: “The pilot studies were sort of a dress rehearsal. We went through all the procedures, including randomization, and we delivered our intervention, and at the end of each intervention session, that’s when we requested specific information about the session. Were the activities appropriate? Were the health educators appropriate?”
Study 2 also pilot tested shortened versions of the intervention: “We were able to pilot the measures to see if they were clear and could be understood by the women--whether the literacy level was appropriate. We piloted the recruitment procedures. Probably the biggest thing we learned from the pilot was that we needed to add a family component to the intervention.”
Study 3 conducted interviews and focus groups to find out women’s perceptions about their experiences with mammography screening.
Study 1 used theatrical testing “where we had members of the community actively participating as consultants in each of the components of the study, and then evaluated it for its appropriateness, in terms of linguistic and cultural relevance.”
Intervention Components
The interviewees highlighted the main components they included to make the interventions culturally sensitive. These components were related to the demographic characteristics, cultural norms, and social environment of participants.
Demographic characteristics of delivery agents and participants were matched in some of the studies. Study 1 hired health educators who were African American females, and about 95% of the research team was also African American. Study 2 presented intervention materials in English and Spanish and had bilingual staff.
Although Study 3 did not plan to match gender characteristics of interventionists and participants, the intervention counselors were of mammography-seeking age, a similar age of participating women: “We wanted to have telephone advisors and counselors who were mature and who could relate to women.”
Taking into account the cultural norms of the target population was also relevant in studies 1 and 2 when selecting intervention activities and materials:
“We wanted to look at symbolism because clearly that is an important cultural component. Even the logo that we eventually used was symbolic of African culture” (Study 1).
Study 2 also took into account Hispanic cultural symbolism in some group activities, in which “all the decorations had a fiesta style.”
In Study 1, the researchers emphasized the importance of cultural congruence:
“For example, in our study one of the key themes was to be safe for yourselves, your family, and your community. In African American communities young women are important, not only to their family, but to their community. So the whole issue of altruism, collectivism, which is an African American trait, was emphasized” (Study 1).
Studies 2 and 4 included ethnic foods of the target population. In Study 4, interventionists taught African Americans “ways to either avoid fried food or preparing that food in ways that didn’t involve so many extra calories.”
In studies 1 and 2, culturally sensitive music and poetry were also incorporated into the intervention. The researcher from Study 1 stated the intervention included materials from African American artists such as the musician Lauren Hill and the poet Maya Angelou. Study 2 introduced music that participants would like: “We definitely had a Latin flavor to the music that we used for the physical activity sessions. We had salsa dancing at our different functions.”
The social context of the target population was another intervention component in 3 studies:
“Our intervention addressed the realities of being an African American woman. What are the threats in the community? What are the barriers to practicing safer sex? We also addressed future orientation as perceived by African Americans. A lot of them don’t perceive they have a future. You also have to address gender norms, critical issues that not only in African-American communities are prominent, but in general” (Study 1).
Study 2 included social support groups for participants and also met their transportation needs to attend sessions: “Women came together at the end of each of our group sessions, and had an opportunity to socialize and talk about their successes and failures with the program, which we felt was a critical element in maintaining their involvement in the program.”
In Study 4, the weight-control specialist provided nutrition advice to participants based on their cultural background or the neighborhood: “Our whole approach to weight-control programs is focused much more on the food environment and much less on the psychological characteristics of our participants. There were was a big difference between African Americans and Caucasians in terms of the food environment. That was at least partly based on the fact that in general the African Americans came from lower social economic levels and lived in different neighborhoods; therefore they had less money to spend on healthy foods and healthy foods were less available to them.”
Main Lessons Learned
Two themes emerged as common lessons among interviewees: the tailoring process has to be individually oriented and is time-consuming.
“I think that is one reason why our interventions are not nearly as effective as they could be, because they are so broad. By designing a really broad intervention it is really targeted at no one” (Study 1).
The PI of Study 1 also mentioned that researchers need to understand the target population and involve individuals from this population in the intervention design, implementation, and evaluation: “The more tailoring you do and the more personalized you make it, the better it is. So there are different levels of tailoring. Tailoring is not a yes or no issue. Think of tailoring as a continuum. Your intervention has to target an individual, not a group.”
The main lesson for researchers in Study 2 was acknowledging the heterogeneity of the target population:
“If you have a group of Latinas living in Denver, in terms of acculturation and nationality there is a lot of diversity. I think the main lesson is that with tailoring you have to be extremely flexible. We incorporated family night because of our pilot study participant feedback, but there were some women who said, ‘I don’t care what my family thinks, I’d rather have an evening where they stay at home and I can just enjoy my time with the other women here.’ In terms of language and bilingualism, we have monolingual Spanish speakers, monolingual English speakers, and people who are bilingual. I think the lesson is to not make narrow stereotyped assumptions because there is so much diversity in each ethnic group” (Study 2).
For researchers of Study 3, the culturally sensitive process “is laborious and time consuming.” Additionally, in retrospective Study 3 researchers would have oversampled racial and ethnic minorities in order to “do some better comparisons across race and ethnicity.”
The PI of Study 4 also emphasized the importance of an individually oriented tailoring process:
“We have to realize that our interventions don’t work very well with everyone. But I don’t think it has anything to do with tailoring. It has to do with the huge difficulty everyone has in changing their habits, food choices, given that we are living in an extremely unhealthy food environment. So when you think about behavior modification procedures, they are all about tailoring to begin with. In other words, the whole idea is teach general principles, but then help people apply those principles to their particular life situations, and that is true regardless of who they are. Participants want a helper who addresses their particular challenges, as opposed to just applying a one size fits all” (Study 4).
Our case study analyses indicate that all projects affiliated with the HMC included ethnic minority participants, as required by NIH funding guidelines. Also, most of the PIs reported to having used individual tailoring strategies to make their interventions more responsive to their target populations regardless of the ethnicity background of participants. This case study highlights that intervention tailoring explicitly applied to ethnic minorities was rarely performed in the HMC interventions.
We found that culturally sensitive tailoring efforts in the HMC projects focused mainly on conducting individual tailoring to meet particular needs of target populations (ie, easy access to classes, transportation, adequate schedules, literacy level), without further tailoring the interventions more specifically for their minority participants. In other words, in most HMC projects both minority and nonminority participants were exposed to the same tailored intervention. Notwithstanding this finding, the practice of individual tailoring is of great significance in behavioral research. Although our study did not investigate the effects of intervention tailoring on health outcomes, considerable research shows that tailoring efforts yield effective changes in behavioral health outcomes.3439,41
From the follow-up interviews with PIs who worked to make their interventions culturally sensitive to an ethnic minority group, we learned that formative research plays a key role in the tailoring process. This finding is consistent with previous research.15,34,35,42 Additionally, we found that the tailored interventions for ethnic minorities included the following cultural components: materials and activities that were congruent with the participants’ demographics (ie, ethnicity, language, and age), cultural norms and practices (ie, ethnic foods, music), and social environment (ie, socioeconomic status, social support need, gender bias). These findings resonate with studies in the literature that also examined components of culturally sensitive interventions for minorities.27,28,31 Finally, the PIs highlighted that cultural tailoring for ethnic minorities has to be individually based and is time-consuming.
This study has limitations due to its descriptive and qualitative nature and specific focus on HMC-affiliated projects. Despite its limitations, this case study is instructive in that it provides valuable insights into the individual and cultural tailoring process of long-term behavioral interventions. Although it is worth noting that the main goal of the HMC-affiliated projects was not to address health disparities, further steps for HMC members, and behavioral scientists in general, may be to explore the extent to which tailoring or adapting long-term maintenance behavior interventions for ethnic minorities can be efficacious and reduce health disparities.
In conclusion, our case study showed the adoption of individual tailoring in general, but less ethnicity–specific tailoring in the HMC projects. Case study findings may suggest the need to address a major research and practice gap. The maintenance behavior research and health disparities field can benefit from more attention to the application of the cultural sensitivity paradigm. There are some research questions that require our immediate attention. To what extent do processes of culturally tailoring long-term interventions for ethnic minorities change and sustain their health outcomes? What are effective tailoring strategies in maintenance interventions for ethnic minorities?
As the United States becomes more ethnically diverse and health disparities persist, the application of the cultural sensitivity paradigm in behavioral research with minorities will become increasingly important. In a review of population-based interventions engaging ethnic minorities in healthy living, Yancey et al43 call for rigorous trials in multi-ethnic and ethnic-specific settings to obtain sufficient evidence on the effectiveness of tailored interventions targeting these diverse groups. The IOM also underlines that culturally appropriate education programs are key in comprehensive, multilevel strategies to eliminate ethnic health inequalities.2 In addition, previous research confirms that behavioral interventions tailored to meet the cultural and social context of ethnic minorities are more likely to increase the external validity of interventions,42 accelerate advances in minority health,32,44 and address health disparities.30,32 Previous systematic reviews, which present evidence of the effectiveness of interventions tailored for minority groups,45,46 conclude that the tailoring process should consider community involvement, face-to-face interventions, inclusion of lay facilitators, and formative research activities.
