Checklist for Measuring Study Quality

Description

This checklist offers a comprehensive critical appraisal tool for public health practitioners, policy-makers and decision-makers. The tool is a step-by-step, easy-to-use assessment suitable for all quantitative study methodologies.

Steps for Using Method/Tool

The checklist consists of 27 ”yes” or “no” questions organized into five sections:

Study quality
External validity
Study bias
Confounding and selection bias
Power of the study

Each section includes instructions and a scoring system for individual sections and a final overall score.
