まとめ
認知行動療法 (Cognitive-behavioral therapy, CBT) は 時間の動機付け理論に照らして 価値と衝動性といった要素を ターゲットにすることで 学生の遅延を 大幅に減少させました 期待は変わりませんでしたが 自己効用は改善され 学術的・心理的な利点の 可能性が示されました
科学分野:
- 心理学
- 行動科学
- 教育心理学
背景:
- 遅延は学生の間でよく見られ 学業の成績や 心理的幸福に悪影響を及ぼします
- 既存の認知行動療法 (CBT) の介入は有望だが 標的を絞った修正が必要である.
- 時間の動機付け理論 (TMT) は 価値,期待,衝動性を通して 遅延を理解するための枠組みを提供します.
研究 の 目的:
- TMT要因に焦点を当てて,生徒の先延ばしに対する改変CBT介入を評価する.
- 先延ばし,価値,期待,衝動性,自己効能,そして全体的な幸福に対する介入の影響を評価する.
主な方法:
- ランダム化制御試験では 71人の大学生が 先延ばしを報告した.
- 参加者はオンラインCBT介入グループか 待合リストの対照グループに割り当てられました
- 先延ばしのレベルとTMT因子は,介入前と後に測定されました.
主要な成果:
- CBT介入グループでは,遅延が著しく減少した (コーエンのd=1. 09).
- 値と衝動性の改善は認められたが,期待の改善は認められなかった.
- 自己効能は増加したが,全体的な幸福度は変わらなかった.
結論:
- 改変されたCBTの介入は 認知の再構築よりも 行動戦略に影響を与えることで 学生の遅延を効果的に軽減します
- この発見はTMTの枠組みを支持し,CBTが遅延を緩和する可能性を強調しています.
- 長期的な効果を理解するためにさらなる研究が必要である.

02:01Group 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...

Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.

01:24Rational Emotive Behavior Therapy
111
Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

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.

Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
