Study Notes

Mixed Methods/Other Research & Systematic Reviews

This presentation covers mixed methods research, systematic reviews, and various research types.

Mixed Method Research

Mixed methods research integrates quantitative (QUANT) and qualitative (QUAL) data and strategies in a single study.
This approach can enrich inquiries by triangulating quantitative and qualitative data.
Certain research questions require mixed methods, known as pragmatism.
Advantages include complementarity, practicality, and enhanced validity.

Mixed Method Designs

Mixed methods designs consist of components–core (fundamental) and supplemental (supportive) components.
Core component, when necessary, can stand alone and provide a theoretical basis
A core component always details the complete and rigorous research method. It also addresses the research questions.
Two designs-concurrent (both quantitative and qualitative data collected simultaneously) and sequential (qualitative then quantitative or vice versa, phases.)
Convergent parallel – obtains different but complementary data.
Explanatory design– quantitative data followed by qualitative data.
Exploratory design– qualitative data gathered first, followed by quantitative data.

Other Special Types of Research

Intervention research explores health services and outcomes.
Survey research involves quantitative data (prevalence, distribution, relations of variables)
Secondary analysis uses previously collected data to address new questions.
Delphi surveys are for short-term forecasting using a panel of experts who complete rounds of questionnaires to achieve consensus.
Methodological research focuses on development, validation, and evaluation of research tools and instruments.

Clinical Trials

Phase I establishes safety, tolerance, and dose.
Phase II seeks preliminary evidence of effectiveness.
Phase III fully tests treatment efficacy (often randomized clinical trials)
Phase IV assesses external validity in the general population; examines generalizability.
Practical clinical trials help make real-world decisions.

Evaluation Research

Process analysis describes a program's implementation process.
Economic analysis assesses program benefits versus costs.

Nursing Intervention Research

This approach focuses on planning, developing, and testing interventions, especially complex ones.
Key concepts include efficacy research, basic developmental research, and pilot research to drive effective interventions.

Health Services Research

Designed to document quality and effectiveness.
Often focuses on Donabedian's key concepts (structure, processes, and outcomes of care.

Outcome Research

Subset of health services research.
Examines the end results and effectiveness of health care practices.

Survey Research

Provides quantitative data on prevalence, distribution, and interrelations of variables.
It can be cross-sectional or longitudinal.
Data is primarily gathered in correlational studies from non-clinical populations.
Modes of gathering data are personal (face-to-face), telephone, and self-administered questionnaires.

Secondary Analysis

Uses existing data to address new research questions.
It can be cost-effective but requires careful assessment of data quality.

Delphi Surveys

This technique uses expert panels in multiple rounds of questionnaires to achieve consensus, usually for short-term forecasting.

Methodological Research

Focuses on developing, validating, and evaluating research tools.

Systematic Reviews

Comprehensive and unbiased synthesis of relevant studies.
Provides a strong foundation for clinical practice guidelines and protocols.
Distinguishes between secondary and primary research.

History of Systematic Reviews

Archie Cochrane emphasized the importance of using available evidence appropriately.
The 1990s saw the rise of the Cochrane Collaboration and the Cochrane Database of Systematic Reviews.
Systematic reviews have evolved, encompassing meta-analyses and varied methodologies.

Importance of Systematic Reviews

Uncovers international evidence.
Confirms and clarifies current practice, addressing variations.
Identifies areas for future research.
Investigates conflicting results.
Guides decision-making.

Types of Systematic Reviews

Meta-analysis statistically integrates results from relevant studies.
Meta-synthesis integrates qualitative data for novel interpretations.

Remember

High-quality systematic reviews prioritize methodological rigor.
Explicit and exhaustive reporting of methods and criteria is paramount.
Reviews should be transparent—reproducible; they cannot be done by one single researcher.

Standards for Systematic Reviews

Maintain quality through adherence to methods and clear reporting.
Follow reporting standards (PRISMA, JBI Reviewer's Manual, Cochrane Handbook.)

PRISMA Diagram

Provides a visual representation of systematic review methodology.

High-Quality Systematic Reviews

Articulate objectives and questions clearly.
Develop protocols with defined inclusion/exclusion criteria.
Search widely for published and unpublished studies.
Critically review and analyze included studies.
Present and synthesize findings transparently.
Transparent reporting.

Planning a Systematic Review

Ensures adequate topic expertise and methodological rigor among the involved reviewers.
This is necessary to ensure adequate library and statistical support.

Meta-Analysis Advantages

Objectivity.
Increased power.
Reduced type II error.
It is not appropriate in all cases.

Using Meta-Analysis

Ensure statistical integration is suitable.
Maintain consistent research questions and hypotheses.
Avoid combining incompatible data ( apples and oranges).
Ensure a sufficient knowledge base with enough studies of acceptable quality.
Results should be varied but not contradictory.

Analytic Decisions

Choosing the effect size index.
Assessing heterogeneity.
Conducting subgroup analyses (if applicable).
Determining publication bias.

Heterogeneity

Assessing heterogeneity is crucial in meta-analysis.
Forest plots are often used for visual assessments.
Subgroup analyses investigate factors contributing to variation across studies.
Key variation factors include characteristics of the participants, study design (RCTs, quasi-experiments), and intervention characteristics (like intervention durations).

Meta-synthesis

Meta-synthesis integrates qualitative data through rigorous analysis.
It is distinct from a traditional literature review.
It yields novel interpretations, going beyond just summing study findings.

Meta-synthesis: Ongoing Debates

Strategies for handling differing qualities of studies.
Balancing the need to integrate across different, possibly conflicting qualitative traditions.

Meta-synthesis Steps

Precise problem formulation.
Selection criteria for relevant literature.
Thorough literature searches.
Assessing data quality.
Data extraction and analysis.
Interpretation of findings.
