Qualitative vs. Quantitative Research on Type 2 Diabetes in Asian Americans
This paper compares two research methodologies—quantitative and qualitative—as applied to the study of type 2 diabetes among Asian Americans. Drawing on a large-scale descriptive quantitative study using California Health Interview Survey data (Choi et al., 2013) and a qualitative community-based pilot intervention targeting Sikh Asian Indians in New York City (Islam et al., 2014), the paper examines each study's conceptual framework, design, findings, and limitations. It argues that while quantitative methods identify population-level trends and risk patterns across ethnic and gender subgroups, qualitative methods capture lived experience and culturally specific responses to prevention programs. Together, both approaches offer a more complete understanding of this complex public health challenge.
- Introduction: Research Approaches and Type 2 Diabetes: Defines qualitative and quantitative research; frames Asian American diabetes study
- Quantitative Study: CHIS Survey of Asian American Subgroups: Descriptive CHIS survey examines ethnicity and gender diabetes patterns
- Design, Methods, and Ethical Considerations: Chi-squared analysis of telephone survey data; ethical standards met
- Findings and Limitations of the Quantitative Study: Filipino and Korean subgroups show highest diabetes risk by gender
- Qualitative Study: Community-Based Diabetes Prevention Among Sikh Americans: DPP-based pilot uses community health workers with Sikh Americans
- Comparing the Two Methodologies: Contrasts subjectivity of qualitative with rigidity of quantitative design
- Conclusion: The Value of Mixed Approaches in Health Research: Both methods together best capture diabetes as a public health issue

What makes this paper effective
- The paper uses two real peer-reviewed studies as parallel case examples, giving the methodology comparison concrete grounding rather than remaining abstract.
- It fairly presents strengths and weaknesses of both research types, avoiding advocacy for either approach and culminating in a balanced integrative conclusion.
- The analysis connects methodological choices to real-world consequences—such as how qualitative feedback allows researchers to shift focus mid-study, while quantitative design cannot.
Key academic technique demonstrated
The paper demonstrates comparative analysis as a structured academic technique: each study is introduced with its conceptual framework, then evaluated on design, data collection, findings, and limitations before a side-by-side synthesis. This mirrors the format expected in research methods courses where students must show they understand not just what studies found, but why each approach was chosen and what trade-offs it entails.
Structure breakdown
The paper opens by defining qualitative and quantitative research and establishing the relevance of both to diabetes risk in Asian Americans. It then analyzes the Choi et al. (2013) quantitative CHIS study across three sections covering design, ethics, findings, and limitations. The Islam et al. (2014) qualitative pilot study is treated next, with similar analytical depth. A comparative section directly contrasts the two approaches, and a brief conclusion argues for using both methods together in health research.
Introduction: Research Approaches and Type 2 Diabetes
Research study types tend to fall into two distinct categories: qualitative and quantitative research. Quantitative research studies are data-driven and seek to answer a particular research question. Qualitative research studies are open-ended and inductive in their techniques; even when they use statistical data, their focus is experiential. When assessing the impact of a lifestyle disease like type 2 diabetes, it is particularly important to consider the lived, subjective experiences of participants, despite objections from some quarters that qualitative research is not real science.
While it may be true that the risks of developing the condition can be mitigated through weight loss and healthier eating, individuals do not always show a willingness to make lifestyle changes until it is too late. Genetic factors predispose certain individuals to an increased likelihood of developing diabetes, but environment and personal decisions also play a significant role. With this in mind, analyzing both quantitative and qualitative studies regarding Asian Americans' specific predisposition to developing type 2 diabetes can be highly instructive.
Quantitative Study: CHIS Survey of Asian American Subgroups
In a study by Choi et al. (2013) using the California Health Interview Survey (CHIS) of California adults aged 18 and older (n = 46,091), demographics related to ethnic and gender-based populations of individuals with diabetes were assessed to determine patterns of manifesting the disorder among Asian Americans. The approach of the study was descriptive in nature. While many quantitative studies utilize the scientific method of constructing a hypothesis that can be either proved or disproved based on the structure of the experiment, this study merely attempted to identify trends—specifically, the extent to which gender and ethnicity influenced participants' tendency to manifest obesity. Descriptive studies are often used to support and shape later studies that have a more clearly hypothesis-driven argument.
As such, this study had no particular overriding conceptual framework. Supporting its design was the notable observation that patterns of obesity often appear to be affected by genetic influences related to race, and that diabetes is a disease more prevalent among males than females in the population as a whole. The researchers attempted to ascertain whether these patterns held true for the Asian American subset population, but stated no specific preliminary hypothesis about what they expected to find. They also did not determine beforehand whether certain Asian American populations would be more likely to manifest diabetes; rather, they examined the data and reported their findings.
Design, Methods, and Ethical Considerations
The source of the data was the CHIS, a twice-annual telephone survey of randomly selected Californians of various races who are asked to answer health-related questions. To analyze the statistical data gathered by the study, a chi-squared test was used to compare the prevalence of type 2 diabetes among different racial and ethnic categories assessed by the CHIS for both genders. Given the minimal risk to participants and the voluntary nature of participation, the study was considered ethical according to acceptable standards of research conduct.
Qualitative Study: Community-Based Diabetes Prevention Among Sikh Americans
In contrast, the qualitative case study by Islam et al. (2014) examined the use of community health workers to deliver culturally specific education to a high-risk group for diabetes. The Indian subcontinent has seen one of the most notable spikes in diabetes due to rising affluence, and this trend is also evident among many Asian and East Asian populations within the United States. The conceptual framework of the study was a multicultural philosophy, stressing that different groups have different health education needs, even when the disease in question is present across cultures. The framework used to educate participants was the evidence-based Diabetes Prevention Program (DPP), which has been found more effective in reducing the progression of diabetes in pre-diabetics than medications.
Requirements for participation included self-identification as a Sikh American and overweight status. BMI criteria specific to Asian populations were applied, as these populations have traditionally manifested diabetes at lower BMIs than Caucasian populations. After initial screening, 175 individuals were selected to participate in specific New York City-based communities. Six facilitated, face-to-face sessions of two hours each with a community health worker covered topics such as improved nutrition and exercise, followed by phone interviews to reinforce the message.
To assess the efficacy of the program, participants were interviewed about their perceptions of the experience. BMI and other markers of health status were also measured. Overall, based on patient reactions, the approach was deemed effective. The qualitative method allows participants to give feedback and specifically detail what aspects of the program worked for them and why they believed it worked. In contrast to a quantitative study—where only predetermined variables can be assessed—the researchers' focus in a qualitative study can shift and change based on the input of participants over the course of the intervention.
Conclusion: The Value of Mixed Approaches in Health Research
Ultimately, using both methods is best for gaining a full understanding of a complex phenomenon such as diabetes within a specific population group. Although qualitative methods may not be as rigorous as those used in the natural sciences, when making decisions about public policy and health-related issues, researchers are assessing effects on human beings—not merely attempting to understand the phenomenon in the abstract. Qualitative research has a legitimate and important place within the field of health research, as it does throughout the social sciences.
