Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches01:23

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...
Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
Confounding in Epidemiological Studies01:27

Confounding in Epidemiological Studies

Confounding in statistical epidemiology represents a pivotal challenge, referring to the distortion in the perceived relationship between an exposure and an outcome due to the presence of a third variable, known as a confounder. This variable is associated with both the exposure and the outcome but is not a direct link in their causal chain. Its presence can lead to erroneous interpretations of the exposure's effect, either exaggerating or underestimating the true association. This phenomenon...
Humanistic Psychology01:24

Humanistic Psychology

Humanistic psychology emerged in the mid-20th century as a response to the deterministic and pessimistic nature of behaviorism and psychoanalysis. While behaviorism focused on observable behaviors influenced by the environment and psychoanalysis delved into unconscious motivations, both theories suggested that human actions lacked free will. In contrast, humanistic psychology offers a perspective that emphasizes the innate potential for goodness and growth within every individual.
This approach...
Qualitative Analysis01:10

Qualitative Analysis

Qualitative analysis is the process of identifying elements, ions, or compounds in an unknown sample. It is the first and most fundamental type of analysis based on the hierarchy of analytical goals. This hierarchy is significant as it provides a structured approach to scientific research, with qualitative analysis serving as the initial step, providing essential information before moving on to quantitative or other forms of analysis.
There are two main approaches to qualitative analysis:...

Summary
This summary is machine-generated.

Mixed methods research in health is supported by some structures but hindered by a lack of training and reporting templates. Researchers can drive structural changes to better utilize mixed methods research.

Area of Science:

  • Health Research Methodology
  • Interdisciplinary Studies

Background:

  • Mixed methods research, combining qualitative and quantitative approaches, is increasingly used in health studies.
  • Structural factors influencing the effective implementation of mixed methods research have received limited attention.

Purpose of the Study:

  • To explore the facilitators and barriers impacting the undertaking of mixed methods studies within health research.

Main Methods:

  • Conducted face-to-face, semi-structured interviews with 20 health researchers experienced in mixed methods research in the United Kingdom.

Main Results:

  • Facilitators included perceived funding body support and multidisciplinary university departments.
  • Barriers comprised a lack of mixed methods training and standardized reporting templates, alongside the influence of the 'hierarchy of evidence' prioritizing randomized controlled trials.
  • Integration and dissemination of mixed methods findings often relied on researcher effort due to structural constraints.

Conclusions:

  • The UK health research environment supports the *initiation* of mixed methods research but not its full potential exploitation.
  • Achieving the full potential of mixed methods research necessitates structural changes and shifts in researcher behavior.
