Assessing decentering: validation, psychometric properties, and clinical usefulness of the Experiences Questionnaire in a Spanish sample.
Decentering is defined as the ability to observe one’s thoughts and feelings in a detached manner. The Experiences Questionnaire (EQ) is a self-report instrument that originally assessed decentering and rumination. The purpose of this study was to evaluate the psychometric properties of the Spanish version of EQ-Decentering and to explore its clinical usefulness. The 11-item EQ-Decentering subscale was translated into Spanish and psychometric properties were examined in a sample of 921 adult individuals, 231 with psychiatric disorders and 690 without. The subsample of nonpsychiatric participants was also split according to their previous meditative experience (meditative participants, n = 3…
Propiedades psicométricas de la versión española de la Philadelphia Mindfulness Scale
Resumen Introduccion La Philadelphia Mindfulness Scale (PHLMS) es un cuestionario breve que evalua 2 componentes clave de la atencion plena: la conciencia en el momento presente y la aceptacion. El presente estudio evalua las propiedades psicometricas de la version espanola de la PHLMS tanto en una muestra control de estudiantes universitarios como en poblacion con patologia psiquiatrica. Material y metodos Se administro la version espanola de la PHLMS a 395 voluntarios (256 con patologia psiquiatrica y 139 estudiantes). Resultados El analisis factorial exploratorio de la version espanola de la PHLMS apoya la solucion bifactorial de la version original con una varianza explicada del 44,02%.…
Grey matter microstructural alterations in schizophrenia patients with treatment-resistant auditory verbal hallucinations.
Treatment-resistant auditory verbal hallucinations (TRAVH) are a relatively prevalent and devastating symptom in patients with schizophrenia (SCZ). Even though their pathological mechanisms are poorly understood, they seem to differ from those underlying non-hallucinating SCZ.& nbsp; In this study, we characterise structural brain changes in SCZ patients with TRAVH. With respect to nonhallucinating patients and healthy controls, we studied macrostructural grey matter changes through cortical thickness and subcortical volumetric data. Additionally, we analysed microstructural differences across groups using intracortical and subcortical mean diffusivity data. This latter imaging metric has b…
