          Abstract

          Abstract Background : the Perseverative Thinking Questionnaire (PTQ) is a global measure of repetitive negative thinking, a core transdiagnostic dimension of mental health. Objectives: this study sought to examine the factor structure, reliability, and evidence of associative validity of the PTQ in Peruvian undergraduates. Method: data from 240 undergraduates (Mage = 20.33, 59% female) were evaluated with confirmatory factor analysis. After finding the best factor structure, reliability was estimated with coefficient omega. The correlation between the PTQ’s latent variable and cognitive fusion was examined as evidence of associative validity. Results: the PTQ proved to be essentially unidimensional since acceptable fit was obtained by the one-factor model with three correlations between errors (CFI = .945; RMSEA = .079). Reliability was high (ω = .927). The correlation between the PTQ and cognitive fusion was very large (ϕ = .876). Conclusion: the PTQ is an essentially unidimensional measure, thus only a global score should be computed. Associative validity should be further examined in future studies.

          Resumen Antecedentes : el Cuestionario de Pensamiento Perseverativo (PTQ) es una medida global del pensamiento negativo repetitivo, una dimensión transdiagnóstica central de la salud mental. Objetivos: este estudio buscó examinar la estructura factorial, la confiabilidad y la evidencia de validez asociativa del PTQ en estudiantes universitarios peruanos. Método: los datos de 240 estudiantes universitarios (Medad = 20.33, 59% mujeres) se evaluaron con análisis factorial confirmatorio. Después de encontrar la mejor estructura factorial, se estimó la confiabilidad con el coeficiente omega. La correlación entre la variable latente del PTQ y la fusión cognitiva se examinó como evidencia de validez asociativa. Resultados: el PTQ demostró ser esencialmente unidimensional, ya que se obtuvo un ajuste aceptable mediante el modelo de un factor con tres correlaciones entre errores (CFI = .945; RMSEA = .079). La fiabilidad fue alta (ω = .927). La correlación entre el PTQ y la fusión cognitiva fue muy grande (ϕ = .876). Conclusión: el PTQ es una medida esencialmente unidimensional; por lo tanto, solo se debe calcular una puntuación global. La validez asociativa debe examinarse más a fondo en futuros estudios.

            From alpha to omega: a practical solution to the pervasive problem of internal consistency estimation.

            Coefficient alpha is the most popular measure of reliability (and certainly of internal consistency reliability) reported in psychological research. This is noteworthy given the numerous deficiencies of coefficient alpha documented in the psychometric literature. This mismatch between theory and practice appears to arise partly because users of psychological scales are unfamiliar with the psychometric literature on coefficient alpha and partly because alternatives to alpha are not widely known. We present a brief review of the psychometric literature on coefficient alpha, followed by a practical alternative in the form of coefficient omega. To facilitate the shift from alpha to omega, we also present a brief guide to the calculation of point and interval estimates of omega using a free, open source software environment. © 2013 The British Psychological Society.

              Rethinking Rumination.

              The response styles theory (Nolen-Hoeksema, 1991) was proposed to explain the insidious relationship between rumination and depression. We review the aspects of the response styles theory that have been well-supported, including evidence that rumination exacerbates depression, enhances negative thinking, impairs problem solving, interferes with instrumental behavior, and erodes social support. Next, we address contradictory and new findings. Specifically, rumination appears to more consistently predict the onset of depression rather than the duration, but rumination interacts with negative cognitive styles to predict the duration of depressive symptoms. Contrary to original predictions, the use of positive distractions has not consistently been correlated with lower levels of depressive symptoms in correlational studies, although dozens of experimental studies show positive distractions relieve depressed mood. Further, evidence now suggests that rumination is associated with psychopathologies in addition to depression, including anxiety, binge eating, binge drinking, and self-harm. We discuss the relationships between rumination and worry and between rumination and other coping or emotion-regulation strategies. Finally, we highlight recent research on the distinction between rumination and more adaptive forms of self-reflection, on basic cognitive deficits or biases in rumination, on its neural and genetic correlates, and on possible interventions to combat rumination.
