まとめ
ビデオ観察療法 (VOT) は,直接観察治療 (DOT) と比較して,結核治療の観察率を大幅に改善しました. このアクセシブルで効果的で安価なアプローチは 患者の監視に適した代替手段です
科学分野:
- 感染症
- 公衆衛生
- 臨床試験
背景:
- 直接観察治療 (DOT) は1990年代から結核治療の標準となっていますが,患者および提供者に不便をもたらします.
- ビデオ観察療法 (VOT) は,結核治療の監督のためにWHOが条件付け的に推奨する代替手段である.
- この研究では,DOTと比較して治療観察レベルを改善するVOTの有効性を評価しました.
研究 の 目的:
- ビデオ観察療法 (VOT) が直接観察治療 (DOT) に比べて結核治療の観察率を改善するかどうかを評価する.
- 結核の治療における監視方法としてのVOTの有効性と受け入れ性を決定する.
主な方法:
- マルチセンター,分析者盲検,ランダム化制御された優位性試験は,イギリスの22の診療所で実施された.
- 226人の肺結核患者は,ランダムにVOT (毎日スマートフォンアプリによる遠隔観察) またはDOT (週3~5回の個人観察) に割り当てられました.
- 最初の2ヶ月で計画された治療観察の≥80%が完了した.治療意図 (ITT) と制限された分析が行われました.
主要な成果:
- ITT分析では,VOTを受けた患者の70%が,DOTを受けた患者の31% (調整OR5.48,p< 0. 0001) に比べて,主治の結果を達成した.
- 制限された分析では,VOT患者の77%が,DOT患者の63%と比較して,初等結果を達成した (調整されたOR2. 52,p=0. 017).
- 胃痛,吐き気,嘔吐などの一般的な副作用は,VOT患者の14%,DOT患者の8%で報告されました.
結論:
- ビデオ観察療法 (VOT) は,直接観察療法 (DOT) よりも,結核治療の監視のためのより効果的な方法である.
- VOTは,日用および複数の日用量を監視するために,DOTよりも受け入れやすく,有効で,潜在的に安価な代替手段を提供します.
- VOTは,さまざまな環境で多くの患者にとってDOTよりも好ましい可能性があり,治療の遵守と監督を強化します.

Naturalistic Observations
17.1K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Observational Studies
11.0K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Observational Learning
893
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Actor-Observer Effect
375
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...

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...

Data Collection by Observations
14.8K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
