Resumen

La Escala de Pensamientos y Creencias Inútiles sobre la Tartamudez (UTBAS) es demasiado larga. Se desarrolló una escala revisada de 20 ítems (UTBAS-R), que reduce la redundancia y mejora la practicidad para la investigación y la terapia de la tartamudez.

Área de la Ciencia:

Patología del Habla y el Lenguaje; Psicología Clínica; Psicometría

Sus antecedentes:

La Escala de Pensamientos y Creencias Inútiles sobre la Tartamudez (UTBAS) es una medida de 198 ítems para adultos que tartamudean.; Su longitud presenta desafíos prácticos en entornos clínicos y de investigación.

Objetivo del estudio:

Evaluar la redundancia de las subescalas de UTBAS.; Desarrollar una versión más corta y práctica de la UTBAS.

Principales métodos:

Análisis de datos de UTBAS de la base de datos del Centro de Investigación de Tartamudez de Australia.; Se realizaron dos estudios: el Estudio 1 examinó las correlaciones de las subescalas; el Estudio 2 utilizó la teoría de respuesta al ítem y el análisis de ítems para reducir el número de ítems.

Principales resultados:

El Estudio 1 encontró fuertes correlaciones entre las subescalas de UTBAS (r ≥ 0.88), lo que indica redundancia.; El Estudio 2 identificó ítems con efectos de piso/techo, altas correlaciones y mal ajuste, lo que llevó a la selección de 20 ítems.

Conclusiones:

Las subescalas segunda y tercera, junto con 46 ítems, son redundantes.; Se propone una UTBAS revisada preliminar (UTBAS-R) con 20 ítems y una subescala.

Beck's Cognitive Therapy

Beck's Cognitive Therapy

Cognitive therapy is a psychological approach designed to address distortions in thinking, which can lead to negative emotions and unrealistic beliefs. These cognitive distortions often influence how individuals interpret and respond to situations, exacerbating emotional distress. Below are some prevalent cognitive distortions, their characteristics, and examples of how they manifest in thought processes.

Cognitive Therapy

Cognitive Therapy

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

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.
Primary Appraisal:...

Rational Emotive Behavior Therapy

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...

Counterfactual Thinking

Counterfactual Thinking

Counterfactual thinking is a cognitive process wherein individuals mentally reconstruct alternative versions of past events, often beginning with “what if” or “if only.” This reflective mechanism plays a significant role in shaping emotional experiences and guiding future behavior. Though typically triggered by unfavorable or unexpected outcomes, counterfactual thinking can also emerge in mundane, everyday decisions and experiences, revealing its deep entrenchment in...

Self-Presentation: Self-Monitoring and Self-Handicapping

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...
