ABSTRACT
This parallel randomized controlled trial aimed to evaluate the effect of acceptance and commitment therapy (ACT) focused on disrupting repetitive negative thinking (RNT) versus a waitlist control (WLC) in the treatment of depression and generalized anxiety disorder (GAD). Forty-eight participants with a main diagnosis of depression and/or GAD were allocated by means of simple randomization to a 2-session RNT-focused ACT intervention or to the WLC. The primary outcomes were emotional symptoms as measured by the Depression, Anxiety, and Stress Scales-21. Process outcomes included ACT- and RNT-related measures: general RNT, experiential avoidance, cognitive fusion, values, and generalized pliance. At the 1-month follow-up, linear mixed effects models showed that the intervention was efficacious in reducing emotional symptoms (d = 2.42, 95% confidence interval [1.64, 3.19]), with 94.12% of participants in the RNT-focused ACT condition showing clinically significant change in the Depression, Anxiety, and Stress Scales-21 total scores versus 9.09% in the WLC condition (70% vs. 8% in intention-to-treat analysis). The intervention effects were maintained at the 3-month follow-up. No adverse events were found. A very brief RNT-focused ACT intervention was highly effective in the treatment of depression and GAD.

Young adults suffering from generalized anxiety disorder (GAD) show high levels of worry about different domains, with couple relationships being the most frequent one. Excessive worry in this domain might lead to couple dysfunction, which is associated with lower outcomes of cognitive behavioral therapy. The current study analyzes the effect of an individual, 3-session, acceptance and commitment therapy (ACT) protocol focused on repetitive negative thinking (RNT) in the treatment of GAD with couple relationship as the main worry domain. Three young adults with GAD participated in this study. A delayed multiple-baseline design was implemented. All participants completed a 5 to 7-week baseline without showing improvement trends in couple-related worry (Experiences in Close Relationships -Anxiety; ECR-A) and general pathological worry (Penn State Worry Questionnaire; PSWQ). Afterwards, they received the ACT protocol, and a 3-month follow-up was conducted. All 3 participants showed evidence of intervention effects on the ECR-A and PSWQ. The standardized mean difference effect sizes for single-case experimental design were very large for the ECR-A (g= 5.93) and PSWQ (g= 3.19). No adverse events were found. Brief, RNT-focused ACT protocols for treating GAD with couple relationship as the main worry domain deserve further empirical tests

The Penn State Worry Questionnaire (PSWQ) is the gold standard measure of the unspecific worry that characterizes generalized anxiety disorder. This study aims to explore the validity of the PSWQ in Colombia and its measurement invariance across gender and clinical and nonclinical participants. An abbreviated, 11-item version of the PSWQ by Sandín, Chorot, Valiente, and Lostao (2009) was used because the negatively worded items have shown to be problematic for Spanish speakers. Additionally, research has suggested that the negatively worded items of the PSWQ lack of practical utility. The PSWQ-11 was administered to a total of 1045 participants, including a sample of nonclinical participants (N = 710) and a sample of clinical participants (N = 335). The internal consistency of the PSWQ-11 across samples was excellent. The one-factor model showed an acceptable fit to the data. Metric and scalar invariance were observed across gender and clinical and nonclinical samples. In conclusion, the PSWQ-11 seems to be a valid measure of GAD-related worry in Colombia, whereas data on factorial equivalence data warrant the comparison of scores across gender and clinical and nonclinical samples
El Penn State Worry Questionnaire (PSWQ) es la medida principal de la preocupación inespecífica que caracteriza al trastorno de ansiedad generalizada (TAG). Este estudio explora la validez del PSWQ en Colombia y su invarianza de medida entre género y participantes clínicos y no clínicos. Se utilizó la versión abreviada de 11 ítems de PSWQ propuesta por Sandín, Chorot, Valiente y Lostao (2009) porque los ítems redactados negativamente han mostrado ser problemáticos para los hispanohablantes. Adicionalmente, la investigación ha sugerido que los ítems redactados en negativa carecen de utilidad práctica. El PSWQ-11 se administró a un total de 1045 participantes, incluyendo una muestra de participantes no clínicos (N = 710) y una muestra de participantes clínicos (N = 335). La consistencia interna del PSWQ-11 a través de muestras fue excelente. El modelo de un factor mostró un ajuste aceptable a los datos. Se observó invarianza métrica y escalar a través de género y muestras clínicas y no clínicas. En conclusión, el PSWQ-11 parece ser una medida válida de la preocupación tipo TAG, mientras que los datos sobre equivalencia factorial permiten la comparación de puntuaciones a través de género y participantes clínicos y no clínicos

Los efectos positivos del mindfulness en el tratamiento de múltiples problemas psicológicos en diversas poblaciones han popularizado su uso dentro de la psicología clínica en los últimos años. No obstante, las investigaciones empíricas y revisiones teóricas sobre el mindfulness muestran tres usos diferentes del mindfulness dentro de las aproximaciones conductuales: como proceso, como habilidad y como estrategia. Las discrepancias en las definiciones de mindfulness han generado ambigüedad con respecto a qué y cómo se investiga este fenómeno. En este trabajo se realizó un análisis conceptual de las definiciones del mindfulness de acuerdo con los supuestos filosóficos analíticos-conductuales y contextualistas-funcionales. Finalmente, se discutió la importancia de contar con una definición precisa y unánime con el fin de desarrollar una agenda coordinada de investigación en esse campo.
Les effets positifs du mindfulness dans le traitement de plusieurs problèmes psychologiques dans différentes populations ont encouragé la psychologie clinique à l'utiliser au cours des dernières années. Cependant, la recherche théorique et empirique sur les examens de pleine conscience montrent trois utilisations différentes de l'attention dans les approches comportementales: comme un processus, comme une compétance et en tant que stratégie. Les divergences dans les définitions de la pleine conscience ont créé une ambiguïté quant à pourquoi et comment ce phénomène est étudié. Cet article est une analyse conceptuelle de la pleine conscience ayant comme paramètres philosophiques l'analyse du comportement et le contextualisme fonctionnel. La discussion finale tourne autour de l'importance d'avoir une définition précise et unanime en vue d'élaborer un programme coordonné de recherche dans ce domaine.
Os efeitos positivos do mindfulness no tratamento de vários problemas psicológicos em diferentes populações incentivaram a psicologia clínica a utilizá-lo nos últimos anos. No entanto, pesquisas empíricas e revisões teóricas sobre o mindfulness mostraram três usos diferentes desse termo segundo perspectivas comportamentais: como processo, como habilidade e como estratégia. As discrepâncias nas definições do mindfulness geraram ambiguidade em relação àquilo que é pesquisado e como é pesquisado. Neste texto, realizou-se uma análise conceitual das definições do mindfulness tendo como bases filosóficas a análise do comportamento e o contextualismo funcional. Por último, discutiu-se a importância de ter uma definição precisa e unânime com o objetivo de desenvolver uma agenda coordenada de pesquisa nesse campo.
Mindfulness has been widely disseminated in clinical psychology in recent years, due to the positive effects on treating several psychological issues in diverse population. Nonetheless, empirical research and theoretical reviews show three different meanings of mindfulness within behavioral approaches: as a process, as skill, and as a strategy. Discrepancies about mindfulness definitions have brought ambiguity to what and how this phenomenon is studied. A conceptual analysis of mindfulness according to behavioral-analytic and functional-contextualistic philosophical traditions is presented. Finally, it was discussed the relevance of employing a precise and consensual definition of mindfulness to develop a coordinated research agenda in this field.
