Criteria for Causality: Bradford Hill Criteria - II
0 Views •
2025
The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts: Biological Gradient: Also known as the dose-response relationship, this criterion...

Criteria for Causality: Bradford Hill Criteria - I
0 Views •
2025
The Bradford Hill criteria are a group of principles that provide a framework to determine a causal relationship between a specific factor and a disease. There are nine criteria that are pivotal in assessing causality in epidemiological studies. Here's a closer look at Strength, Consistency, Specificity, and Temporality criteria with definitions and examples: Strength: This criterion refers to the size of the association between the factor and the outcome. A strong association suggests a...

2017
Electrophysiological research is an important tool for identifying biomarkers of developmental disorders, including Autism Spectrum Disorders (ASD), but data collection in these populations remains challenging. This work presents a familiarization protocol to accompany research that includes electroencephalography (EEG) to improve the likelihood of collecting EEG data from children with ASD.

Cited by 6 •
2018
The goal of this protocol is to describe in detail the technique of minimally invasive aortic valve replacement through a right anterior mini-thoracotomy and central aortic cannulation. This technique can potentially enhance patients' comfort and, by reducing post-operative morbidity, promote lowering the length of stay and global costs.

In behavioral finance, pension participant behavior refers to the psychological influences shaping individuals' retirement savings decisions. These behaviors can significantly impact long-term financial security and are often driven by cognitive biases and decision-making heuristics.Status Quo Bias in Pension DecisionsOne of pension participation's most prevalent behavioral tendencies is the status quo bias. This cognitive bias leads individuals to prefer existing conditions over making active...
FAQs
Each criterion should serve the research question by identifying characteristics relevant to the behavior or experience under study. Including relevant age, experiences, behavioral patterns, health status, or procedural abilities can reduce confounding variables and improve sample consistency. Criteria with no clear connection may limit recruitment and weaken how confidently findings generalize to broader populations.
Eligibility decisions shape which people enter the sample, so inconsistent or poorly justified criteria can introduce selection bias. When investigators apply the same rules transparently, they can better distinguish effects related to the behavioral question from differences created by recruitment. The resulting findings are easier to interpret because the sample’s composition is explicitly documented.
Health status and procedural ability can determine whether participation is appropriate and whether a person can provide the information or behavioral data required by the study. Considering these factors helps prevent inappropriate study involvement while supporting consistent data collection. Their inclusion in eligibility decisions also clarifies which participants the behavioral findings describe.
Investigators first establish inclusion and exclusion rules that match the study question, then assess potential participants against those rules during recruitment and screening. The assessment may cover age, relevant experiences, behavioral patterns, health status, and ability to complete procedures. Applying the same criteria across candidates promotes consistent sampling and makes eligibility decisions transparent.
Screening can examine characteristics that directly affect the study’s behavioral focus or feasibility, including age, relevant experiences, behavioral patterns, health status, and ability to complete study procedures. The specific combination depends on the research question. Assessing these characteristics helps investigators assemble a sample suited to the intended comparison or behavioral observation.
The selected eligibility rules determine which population the findings most directly represent. Criteria that closely match the research question can support clearer interpretation, while restrictive or narrowly targeted rules may limit applicability beyond the recruited sample. For this reason, behavioral researchers should describe eligibility decisions clearly when judging whether results can extend to broader populations.
