Psy635 Research Design And Methods Week 3 Guidancewelcome To Week 3 T

Welcome to Week 3! This week, we will begin to learn about qualitative research methods. In qualitative research, there is more of an emphasis on philosophy than in quantitative research. This week’s assignments include a discussion and a written assignment. As mentioned last week, the eBooks for this course are found in the ebrary database in the Ashford Library.

If you have not already done so, you will need to create a user name and password for ebrary. You can search for the eBooks you need and save the references to your bookshelf. Then, each time you log in, it will be easy to find and open the books you need for the course. Assigned readings this week are Chapter 1 in the Frost (2011) eBook, and the article by Ponterotto (2013). After completing the readings and activities for the week, you will be able to: differentiate between qualitative and quantitative research paradigms; evaluate philosophical viewpoints that guide qualitative research approaches; and summarize literature on qualitative, quantitative, and mixed methods of research.

Last week, we considered experimental research designs, which fall into the broad category of quantitative research methods. These designs involved measurement (assigning numerical values to characteristics or observations), statistical analysis, and hypothesis testing – concepts that do not apply to qualitative research designs. Qualitative methods involve using words and/or pictures instead of variables and numbers (Frost, 2011). Various forms of a process called coding are used in qualitative research to analyze data in the form of words. Qualitative researchers strive to avoid preconceived notions, so their studies do not begin with a hypothesis.

Some approaches to qualitative research, such as grounded theory, may end with a hypothesis as the result of the research. The hypothesis might then be tested by a quantitative researcher in a new quantitative study, but qualitative research itself does not involve hypothesis testing. While sampling for a quantitative study may be random or some other type of probability sampling, qualitative sampling tends to be purposive. Researchers seek out individuals who have experienced the topic of the study and are willing and able to speak about it in detail. Sample sizes in quantitative research tend to be large in order to have enough data for statistical analysis.

Relatively small sample sizes are used in qualitative research, because the aim is to go deep instead of wide. Being able to generalize findings is not as much of a concern in a qualitative study because it does not claim to necessarily apply to everyone. Research reports in quantitative research are expected to be written in the third person with no use of “I” or “we.” An intentional distance is kept between the researcher and those being studied in an effort to maintain objectivity. However, in a qualitative study, the researcher gets close to the research participants and engages in dialog with them as equals in order to learn their viewpoint and understand their experience on a subjective level (Ponterotto, 2013).

In research reports, a qualitative researcher “writes in a literary, informal style using the personal voice” (Creswell, 2007, p. 17). Concepts and terms such as validity, reliability, and inter-observer reliability or agreement are associated with quantitative research methods. All of these terms have numerical ratings and researchers strive to get as high a score as they can to show that their research is worthwhile. Qualitative researchers, on the other hand, prefer terms such as trustworthiness, dependability, and credibility, and they do not use numbers to measure these characteristics.

Trustworthiness is supported by thick description, reflexivity and bracketing (explaining researchers’ backgrounds and acknowledging how their worldview might affect perception), and member checking (participants review the final report to verify it reflects their experiences). These characteristics are not found in quantitative research reports. Quantitative research is based on the paradigm of positivism—the philosophical view that there is one objective reality that can be measured and agreed upon. Although qualitative research is sometimes called a paradigm, it involves more than one—such as post-positivism, constructivism-interpretivism, and critical-ideological perspectives (Ponterotto, 2013).

Researchers need to identify their own philosophical paradigm or worldview to guide their choice of qualitative methods and research questions. This week’s discussion involves comparing qualitative and quantitative approaches, and analyzing how your chosen research topic from last week could benefit from a qualitative study.

Your assignment is to write a literature review about four research designs: one non-experimental, one quantitative experimental, one qualitative, and one mixed methods. The articles you include should not be original research studies but articles about the research designs and how to use them. Use resources such as the Research Methods research guide in the Ashford Library, which provides general information, videos, and articles about various research methods. You can also search library databases using the name of each research design as a keyword. Contact librarians via live chat or phone if you need assistance.

In your paper, start by briefly describing your Week 1 chosen topic. Then, include a research question suitable for a qualitative study and a hypothesis for a quantitative study. Summarize each of the four articles about research designs, comparing and contrasting their similarities, differences, and the paradigms they imply. Discuss how each design could be used to investigate your topic. Reflect on which design appeals most to you and aligns with your worldview.

Paper For Above instruction

The purpose of this paper is to provide a comprehensive review of four distinct research designs—non-experimental, experimental, qualitative, and mixed methods—analyzing their methodologies, philosophical underpinnings, and applicability to a chosen research topic. This exercise aims to enhance understanding of various research paradigms, their practical applications, and how one's worldview influences research design choices.

For the foundational topic, I have selected the effects of social media on adolescent mental health, a pertinent and timely issue that warrants diverse investigative approaches. Initially, the research question guiding a qualitative study is: "How do adolescents perceive the impact of social media on their mental health and daily life?" This question seeks to explore personal experiences, perceptions, and interpretations to gain in-depth insights. Conversely, a hypothesis for a quantitative study might be: "Higher social media usage is associated with increased levels of anxiety and depression among adolescents," which seeks to measure and statistically analyze the relationship between variables.

Non-Experimental Research Design

The non-experimental research design typically involves observational studies that do not manipulate variables but instead observe existing conditions or phenomena. Articles about this design often highlight its use in descriptive research where the goal is to understand phenomena as they naturally occur. For example, an article by Johnson (2015) discusses observational methods used in community health research to assess social media usage patterns among teens without intervention. Such studies are valuable for establishing correlations and generating hypotheses for further experimental investigation. The research paradigm associated with non-experimental designs is usually post-positivist, acknowledging that observations are subject to biases but aiming to uncover consistent patterns through systematic observation.

Quantitative Experimental Design

Quantitative experimental designs involve the manipulation of variables to establish causal relationships, typically through randomized controlled trials (RCTs). Articles about this design often emphasize methodological rigor, control groups, and statistical analysis. An article by Lee and Kim (2017) illustrates an experimental study examining the effect of a social media intervention on reducing anxiety in adolescents. Such designs are grounded in positivist paradigms, asserting that reality can be measured objectively, and causal inferences can be drawn from controlled experiments. This design is suitable for testing hypotheses about the effects of specific interventions or factors, providing strong evidence for causality.

Qualitative Research Design

The qualitative research design focuses on understanding human experiences, perceptions, and social contexts through detailed, rich data collection methods like interviews, focus groups, or observations. An article by Davis (2018) explores adolescents' perceptions of social media's influence on their mental health through in-depth interviews, resulting in nuanced insights into individual experiences. Qualitative studies are underpinned by constructivist and interpretivist paradigms, emphasizing subjective realities and meaning-making processes. These designs are particularly useful when exploring complex phenomena and developing theories rooted in participants' perspectives.

Mixed Methods Design

The mixed methods approach combines quantitative and qualitative strategies to capitalize on the strengths of both. An article by Chen and Martinez (2019) describes a study integrating surveys measuring levels of anxiety with interviews exploring adolescents' perceptions of social media's impact. This design is aligned with pragmatic paradigms, prioritizing practical solutions and comprehensive understanding over adherence to a single worldview. Mixed methods are valuable for triangulating data, validating findings, and providing a more holistic view of research questions.

Comparison and Reflection

Each research design offers unique advantages suited to different aspects of investigating social media's impact on adolescent mental health. Non-experimental designs are effective for initial exploration and establishing correlations, while experimental designs can test specific interventions' efficacy. Qualitative methods provide depth and contextual understanding, revealing how adolescents interpret their experiences. Mixed methods combine these strengths, offering both breadth and depth.

My personal worldview aligns most closely with constructivism-interpretivism, valuing subjective human experiences and the contextual meanings individuals assign to phenomena. This aligns with my preference for qualitative methods, as I believe understanding the richness of personal perceptions provides vital insights into social phenomena like mental health influences. Nonetheless, I recognize the importance of complementing qualitative insights with quantitative data to build robust, evidence-based conclusions.

Conclusion

Understanding various research designs enhances one's ability to select appropriate methods aligned with research questions and philosophical beliefs. The choice among non-experimental, experimental, qualitative, and mixed methods depends on the specific aims of the study, the nature of the phenomenon, and the researcher's worldview. By appreciating the strengths and limitations of each design, researchers can craft studies that contribute meaningful knowledge to their fields.
