まとめ
自殺的思考 (SI) を直接引き起こしているわけではありません. 代わりに これらの要因は SI自身と共に 基礎レベルからの変化に抵抗し 既存の自殺理論に挑戦します
科学分野:
- 心理学
- 精神科
- 自殺について
背景:
- 自殺の対人理論では 自殺思考 (SI) の主要な原動力として 認知された負担 (PB) と 阻害された帰属感 (TB) を提唱しています
- この理論は,PBまたはTBが被動SIにつながり,両方がアクティブSIに必要であることを示唆しています.
研究 の 目的:
- PB,TB,および受動的およびアクティブなSIの間のダイナミックな連続時間関係を調査する.
- PB と TB が時間とともに SI の変化に耐えるか否かをテストする.
主な方法:
- 3つの独立したサンプル (N=141) の最近の自殺思考/行動を持つ個人のデータに基づく連続時間残留ダイナミック構造方程式モデリングを使用した.
- 参加者は,PB,TB,パッシブSI,およびアクティブSIを評価する,毎日集中的な調査 (28〜30日間) を完了しました.
主要な成果:
- パッシブとアクティブの両方のSIは,変化への抵抗を示し,マイナスの自動漂流効果を示した.
- PB,TB,および受動的SIとアクティブSIの両方の相互作用に対して,重大な負のクロス・ドリフト効果が見つかりました.
- PB,TB,およびその相互作用がSIに及ぼす影響は,約4. 5~5. 5時間持続した.
結論:
- 自殺の対人理論とは対照的に,PBとTBは,SI自身とともに,SIの典型的なレベルを維持するために行動することを示唆しています.
- これらの結果は,PBとTBが確立されたSIレベルからの偏差に抵抗する安定効果を示しています.

01:26Modeling in Therapy
145
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

01:14Avoidance Learning and Learned Helplessness
1.9K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

01:18Models of Health Promotion and Illness Prevention II
1.7K
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
