What is an Experiment?01:12

What is an Experiment?

13.2K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Blinding

2.6K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Controls in Experiments

10.4K
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...

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

174
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,...

科学分野:

  • 公衆衛生
  • 行動科学
  • コミュニケーション研究

背景:

  • ワクチンに関する誤った情報は 高い予防接種率を達成する上で 大きな障害となっている.
  • 誤った情報を修正するための既存の戦略には3つの一般的なメッセージ構造が含まれていますが,その有効性とネガティブな影響の可能性 (バックファイアリング) は不明です.

研究 の 目的:

  • 3つの異なる誤情報修正メッセージ構造がCOVID-19ワクチンおよびブースター意図に与える影響を実験的に評価する.
  • これらのメッセージ構造が予防接種の意図を強めるか弱めるかを評価する.

主な方法:

  • ワクチン安全性に関する懸念を表明した米国の成人と,事前に登録された調査組み込みの実験が行われました.
  • 参加者はランダムにコントロールグループまたは3つのメッセージ条件の1つに分けられました:神話-その後-事実,事実-神話-事実,または事実のみ.
  • 最初のCOVID-19ワクチンまたはブースター接種の意図は,オーダーナルロジスティック回帰を用いて測定および分析されました.

主要な成果:

  • 神話に続く事実によるメッセージの構造は,すでに最初のCOVID-19ワクチンを接種した参加者の間でブースターワクチン接種の意図を大幅に高めました.
  • ワクチン接種の意図において,対照群と,初期ワクチン接種を未開始の個体における誤情報修正条件のいずれかにおいて,有意な差異は認められなかった.
  • メッセージ構造のいずれも参加者のいずれのグループでもワクチン接種の意図を弱めたため",逆効果"の証拠は見つかりませんでした.

結論:

  • "事実に続く神話"のアプローチは,すでにワクチン接種された集団のブースターワクチン接種の意図を強化するのに有効です.
  • 誤った情報を修正する戦略が 逆効果になるという懸念は 研究の結果では裏付けられませんでした
  • "事実に続く神話"のような ターゲットを絞ったメッセージは ワクチン接種率を向上させるための 公共衛生コミュニケーションの 重要なツールとなるかもしれません
