Reliability and Validity01:29

Reliability and Validity

12.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Data Validation01:03

Data Validation

6.4K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Systematic Error: Methodological and Sampling Errors

8.7K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Criteria for Causality: Bradford Hill Criteria - II

1.6K
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:

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

627
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Controls in Experiments

13.1K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Area of Science:

  • Health Services Research
  • Evidence-Based Practice

Background:

  • The quality of literature on external validity is inconsistent.
  • Decision-makers need reliable tools to assess evidence transferability.
  • Existing checklists for external validity require improvement.

Purpose of the Study:

  • To identify and assess current checklists for external validity.
  • To lay the groundwork for a new, improved instrument.
  • To enhance the judgment of similarities between study and implementation settings.

Main Methods:

  • A systematic literature review was conducted across PubMed, Embase, and CINAHL.
  • Checklist items were evaluated based on their methodological justification and frequency of appearance.
  • English-language papers were included without time restrictions.

Main Results:

  • Fifteen papers yielded 21 checklists with 38 unique items.
  • No checklist items were supported by empirical evidence.
  • Most items lacked methodological justification or were based on consensus.

Conclusions:

  • The study provides foundational elements for a new external validity checklist.
  • Future steps include gathering empirical evidence and validating the proposed checklist.
  • A validated instrument will aid in more accurate evidence application.
