まとめ
吃音に関する非協力的思考と信念尺度(UTBAS)は長すぎる。冗長性を減らし、吃音研究や治療の実用性を向上させた改訂版20項目尺度(UTBAS-R)が開発された。
科学分野:
- 言語聴覚療法;臨床心理学;心理測定学測定学測定学測定学測定学測定学測定学測定学測定学測定学測定学
背景:
- 吃音に関する非協力的思考と信念尺度(UTBAS)は、吃音のある成人を対象とした198項目尺度である。その長さは、臨床および研究設定において実用的な課題をもたらす。
研究 の 目的:
- UTBAS下位尺度の冗長性を評価すること。UTBASのより短く、より実用的なバージョンを開発すること。
主な方法:
- オーストラリア吃音研究センターデータベースからのUTBASデータの分析。2つの研究が実施された:研究1は下位尺度の相関を調査した;研究2は項目応答理論と項目分析を用いて項目数を削減した。
主要な成果:
- 研究1では、UTBAS下位尺度の間に強い相関(r ≥ 0.88)が見られ、冗長性が示唆された。研究2では、フロア/シーリング効果、高い相関、適合性の低い項目が特定され、20項目が選択された。
結論:
- 第2および第3下位尺度、ならびに46項目は冗長である。1つの下位尺度を持つ20項目のUTBAS改訂版(UTBAS-R)の予備版が提案される。

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...

Lazarus's Cognitive Appraisal Theory

Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.

Rational Emotive Behavior Therapy

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...

Though typically triggered by unfavorable or unexpected outcomes, counterfactual thinking can also emerge in mundane, everyday decisions and experiences, revealing its deep entrenchment in...

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...
