The Selection Of A Research Design Is Guided By the Studys Purpose An

The selection of a research design is guided by the study’s purpose and research questions and hypotheses, and the design then links the research questions and hypotheses to the data that will be collected. You should keep in mind, however, that the research process is interactive, not necessarily proceeding in a linear fashion from one component to the next. Rather, the writing of research questions could, for example, necessitate adjustments to the study’s purpose statement. Nevertheless, when presented together, the various components of a research study should align. As you learned last week, alignment means that a research study possesses clear and logical connections among all of its various components.

In addition to considering alignment, when researchers select a research design, they must also consider the ethical implications of their choice, including, for example, what their design selection means for participant recruitment, procedures, and privacy. For this Discussion, you will evaluate quantitative research questions and hypotheses in assigned journal articles in your discipline and consider the alignment of theory, problem, purpose, research questions and hypotheses, and design. You will also identify the type of quantitative research design the authors used and explain how it was implemented. Quasi-experimental, casual comparative, correlational, pretest–posttest, or true experimental are examples of types of research designs used in quantitative research.

With these thoughts in mind, refer to the Journal Articles document for your assigned articles for this Discussion. By Day 4 Post a critique of the research study in which you: Evaluate the research questions and hypotheses. The Research Questions and Hypotheses Checklist serves as a guide for your evaluation. Please do not respond to the checklist in a Yes/No format in writing your Discussion post. Identify the type of quantitative research design used and explain how the researchers implemented the design.

Introduction

The selection of an appropriate research design is a critical step in the research process, as it directly influences the validity and reliability of the study's findings. In this critique, we evaluate the research questions and hypotheses of the study by Kwate and Goodman (2015), determine the type of quantitative research design used, and analyze the alignment of the study components.

Evaluation of Research Questions and Hypotheses

Kwate and Goodman (2015) aimed to investigate the effects of racism on mental health among residents of Black neighborhoods in New York City. Their research questions aimed to elucidate the relationship between experiences of racism and mental health outcomes over time, formulated to explore both cross-sectional and longitudinal effects. The hypotheses posited that increased exposure to racism would correlate with worse mental health indicators, such as depression and anxiety levels. These questions and hypotheses are clearly aligned with the study’s purpose to understand the impact of racism on mental health, emphasizing the importance of precise measurement and temporal analysis.

Type of Quantitative Research Design

The researchers employed a longitudinal, correlational research design. This design involved collecting data at multiple time points to observe changes and associations over time. Implementation included recruiting participants from specific neighborhoods, administering standardized measures of racism experiences and mental health symptoms at baseline, and following up over a designated period. The correlational approach allowed the researchers to examine the relationships between variables without manipulating any factors, which is characteristic of observational studies focusing on understanding existing associations.

Implementation of the Research Design

To implement the longitudinal, correlational design, Kwate and Goodman (2015) utilized surveys and validated scales to assess racism exposure and mental health outcomes. Data were collected at multiple intervals, enabling the researchers to analyze patterns and potential causal pathways. The design’s strength lay in its ability to track changes over time, offering insights into temporal relationships. Ethical considerations included ensuring participant privacy and informed consent, especially given the sensitive nature of the topics addressed.

Analysis of Alignment Among Study Components

The study maintained strong alignment among its components. The problem of racial disparities in mental health set the foundation, with the purpose clearly aimed at examining the influence of racism. The research questions derived from this purpose, seeking to establish correlations over time between racism exposure and mental health issues. The hypotheses directly corresponded to these questions, predicting specific relationships. The chosen longitudinal, correlational design was appropriate to address these questions without manipulation, supporting internal validity and observational integrity.

Furthermore, ethical considerations were integral to the design, with measures taken to protect participant confidentiality. This alignment ensures that the study’s methodology adequately responds to its aims, providing credible and meaningful findings.

Conclusion

In conclusion, the study by Kwate and Goodman (2015) exemplifies a well-aligned research process, with clear connections between the problem, purpose, questions, hypotheses, and chosen design. The longitudinal, correlational approach effectively captured the dynamic relationship between racism and mental health, respecting ethical principles. Such alignment enhances the validity of the findings and contributes to scholarly understanding of racial disparities in health outcomes.
