Campbell Systematic Reviews
|July 23, 2026
Summary
This Campbell mega-map protocol outlines a comprehensive review of evidence on creating age-friendly environments. It aims to identify research gaps and inform future studies and funding decisions.
Area of Science:
- Gerontology
- Public Health
- Environmental Design
Background:
- Growing global aging population necessitates environments supporting older adults.
- Existing evidence on age-friendly interventions is fragmented.
- Systematic reviews and evidence gap maps offer potential synthesis methods.
Purpose of the Study:
- To systematically map existing evidence on interventions for age-friendly environments.
- To identify gaps in research methods, interventions, outcomes, and geographical scope.
- To guide researchers and policymakers in evidence-informed decision-making.
Main Methods:
- Protocol for a Campbell mega-map.
- Comprehensive search strategy for systematic reviews and evidence and gap maps.
- Data extraction and synthesis focused on interventions and environmental factors.
- Gap analysis across methods, interventions, outcomes, and geographies.
Main Results:
- The protocol details the methodology for synthesizing evidence.
- Anticipated results include a comprehensive overview of current research.
- Identification of specific areas lacking sufficient evidence will be highlighted.
Conclusions:
- This mega-map protocol provides a framework for understanding the evidence landscape.
- It will inform the development of effective, evidence-based age-friendly initiatives.
- The findings will guide future research priorities and resource allocation.
