Health Research

A

Philosophical: An all-encompassing term that some engaged in it prefer to use (rather than medical or biomedical research) to describe all forms of biological, behavioral, and/or social science research on all aspects of human health and
disease (Porta, 2018).
Applied: The process of systematically investigating a single, well-defined aspect of physical, mental, or social wellbeing (textbook, page 1)

24
Q

The Research Process

A

Research is the process of systematically and carefully investigating a subject
in order to discover new insights about the world

25
Q

The Five Steps of the Research Process

A
  1. Identify a study question
  2. Select a general study approach
  3. Design the study and collect data
  4. Analyze data
  5. Write and share a report about the findings
26
Q

A More Comprehensive Research Process

A
  1. Research Question
  2. Generate Hypothesis
  3. Collect data
  4. Analyze Data
  5. Interpret findings
  6. Communicate
27
Q

Standard of Health Research: PICOT

A

➢What is the Patient (or Population) group and Problem that will be studied?
➢What is the Intervention that will be tested?
➢What will the intervention be Compared to? What is the Control group?
➢What is the Outcome of interest?
➢What is the Timeframe for follow-up?

If thought carefully can generate evidence and used for interventions

28
Q

What Makes a Question a Good Research Question?

A

1) A real question
2) Testable
3) Generalizable
4) Purposeful

29
Q

A real question

A

Value statement like “mental health is important” or “tobacco use is bad” are not useful for framing
research projects
A research plan should not be formulated based on a predetermined call to action like “people should
exercise more” or “first aid should be a mandatory part of the middle school curriculum”

30
Q

Testable

A

Can be answered using currently developed health research methods

31
Q

Generalizable

A

Research findings must be applicable to beyond the study population, in order to advance science

32
Q

Purposeful

A

Designed to answer one well-defined and specific research question

33
Q

Refining the Study Question

A
  1. What is the one well-defined research question that the study will
    answer?
  2. What specific aims, objectives, or hypotheses will enable the key
    question to be answered?
  3. Would a conceptual framework be helpful for guiding the design,
    analysis, and interpretation of the study and its results?
  4. Is the proposed study feasible?
34
Q

Study Goal

A

The single overarching objective of a research project or the main question that
a research project seeks to answer

35
Q

In Conceptualization of the Study Goal
Consider…

A
  1. What is the one key question that this study will answer?
  2. What is already known about the research topic? What is the gap or limitation in knowledge that needs to be addressed?
  3. What is the significance of the problem that the study will
    address?
  4. What will be innovative about the research project? How will the study resolve the current gap or limitation in knowledge?
  5. What is the likely impact of this research project? If the study is successful, how will it help advance health in relevant populations?
36
Q

Specific Objectives

A

Carefully described action that will help the researcher make progress toward achieving the big-picture goal

The enumerated items should take the form of a question or a “to” statement that uses an
action verb, like “to measure” or “to compare”

37
Q

Most studies in the health sciences have two to four ___________ ______, with three the most typical
number

A

specific aims

38
Q

For experimental studies, the specific aims

A

may take the form of hypotheses that will be
tested

39
Q

Sequential Objective:

A

Chronological list of actions that will achieve the main goal

40
Q

Independent Objective:

A

Related but independent objectives. When one objective is not achieved, it will not
prevent successfully completion of the other objectives

41
Q

The characteristics of a good specific objective can be summarized
using the acronym

A

➢Specific
➢Measurable
➢Attainable (or Achievable)
➢Relevant (or Realistic)
➢Timely (or Time-bound)

42
Q

Theoretical framework:

A

A set of established models in the published literature that can inform the components and flows of the conceptual framework for a new research study

43
Q

We use models in health research

A

➢ To organize our thoughts
➢ To explore determinant/health relationships in a systematic manner
➢ As a guide for analysis
➢ To identify ‘modifiable’ factors for intervention

44
Q

Lalonde’s Model

A

Title: A New Perspective on the Health of Canadians.
Considered to be first modern government doc in Western
context to propose the health field look beyond the
biomedical health care system.

Proposed health field = human biology + environment +
lifestyle + health care organization
