まとめ
同級生主導の性教育は,女の子の性交を減少させたが,男の子の性交は減少しなかった. 無防備なセックスを有意に減らすことはできませんでしたが,ティーンエイジャーの性的健康戦略を改善する見込みを示しました.
科学分野:
- 公衆衛生は公衆衛生である.
- 青少年の健康について
- セックス・エデュケーション・リサーチ・セックス・エデュケーション・リサーチ
背景:
- ティーンエイジャー妊娠の減少は,英国政府の優先事項です.
- 学校での性教育は,重要な戦略です.
- 同級生主導のアプローチの有効性には,評価が必要です.
研究 の 目的:
- 同級生主導の性教育の効果を評価する.
- 同級生主導の性教育と従来の教師主導の性教育を比較する.
- 早期の性的活動と結果への影響を評価する.
主な方法:
- 29校の8000人以上の生徒を対象とした学校ベースのランダム化試験です.
- 介入グループは同級生主導の性教育を受け,対照群は通常の教師主導の教育を受けました.
- プライマリ・アウトカム:16歳までに無防備で初めて異性交をした;治療の意図分析.
主要な成果:
- 同級生主導のグループでは,性交を報告した女の子が少なく,男の子はそうではありませんでした.
- どちらの性別でも,無防備のファーストセックスの有意な差はありません.
- 同級生主導のグループ内の女の子の意図せぬ妊娠の限界的減少.
- 同級生主導の教育に対する満足度が高く,シングルセックスのセッションを好む.
結論:
- 同級生主導の性教育は,いくつかの利点を示していますが,若者の性健康を改善するには,それだけでは不十分です.
- 性健康の成果を向上させるために,より広範な戦略が必要である.
- シングルセックス性教育セッションの有効性に関するさらなる研究が推奨されています.

Group Design
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...
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 child was...
The Stanford Prison Experiment
The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.
Social Proof
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.
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.

Blinding
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.
