まとめ
社会的に獲得されたノセボ効果は,副作用を観察すると,他の治療法に一般化することができます. この研究では ソーシャル・モデリングは ノセボ効果を高めなかったが 頭痛のような一般的な副作用を 増加させたことが分かりました
科学分野:
- 心理学
- 神経科学
- 社会的認知
背景:
- プラセボ治療でも同様の効果を誘発することがあります.
- 社会的に得られた副作用の現象と,異なる治療法へのその潜在的一般化については,まだ十分に研究されていない.
研究 の 目的:
- プラセボ治療の観察によって引き起こされる社会的に得られた副作用が,類似した,しかし同一ではない治療に一般化できるかどうかを調査する.
- ノセボ効果に対する社会的モデルと言語的示唆の影響を調べる.
主な方法:
- 120人の健康なボランティアをランダムに4つのグループに分けました 同じ治療の副作用の社会的モデル化,異なる治療の副作用の社会的モデル化,口頭での提案のみ,そして治療なしのコントロールです.
- 参加者はプラセボの認知強化薬を受けた.
- 報告された副作用の重度が主な評価基準でした.
主要な成果:
- すべてのプラセボグループはノセボ効果を示し,症状の重症度が増加したと報告した.
- ソーシャル・モデリングは,主要なノセボ効果を有意に高めなかった.
- 社会的モデリングは,頭痛とめまいを含む一般的な副作用に添加的効果を示し,これは異なる治療法で一般化しました.
結論:
- 社会的に誘発されたノセボ効果は一貫して発生しないかもしれませんが,同じ治療法を超えて一般化することができます.
- 社会的に得られた副作用,特に頭痛とめまいが,治療法間で一般化することは,さらなる調査を正当化します.
- 治療情報の大規模な共有は,ノセボ効果の社会的負担に寄与する可能性があります.

The Placebo Effect

The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

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.

Pharmacovigilance
989
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

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,...
