Transcranial direct current stimulation (tDCS) has been studied to enhance extinction-based treatments for anxiety disorders. However, the field shows conflicting results about its anxiolytic effect and only a few studies have observed the extinction of consolidated memories. We looked to study the effect of offline 1 mA tDCS over the right dorsola...
Article
Objectives Evidence shows that Acceptance and Commitment Therapy (ACT) is an empirically supported psychological approach for chronic pain (CP) management. Although self-compassion is not explicitly a target of ACT, it seems to be one mechanism of change in ACT for CP. However, research is lacking on the benefits of including explicit self-compassi...
Article
Cortical thickness has been increasingly studied in the context of structural-brain-behavior associations, such as anxiety; however, the literature is scattered across methods and research fields. This scoping review aims to summarize the available data concerning the association between cortical thickness and anxiety-related measures and identify...

These include brain stimulation techniques that do not require surgery and that are nonpharmacological and non-psychotherapeutic. NIBS that have showed antidepressant effect so far in...
Article
Acceptance and Commitment Therapy (ACT) has been widely tested for chronic pain, with demonstrated efficacy. Nevertheless, although there is meta-analytical evidence on the efficacy of face-to-face ACT, no reviews have been performed on online ACT in this population. The aim of this meta-analysis is to determine the efficacy of online ACT for adult...

Transcranial direct current stimulation (tDCS) has been studied as an add-on enhancer of extinction-based treatments for anxiety disorders. However, previous studies have failed to address one issue of translational significance: the to-be extinguished fear memory must be consolidated. Additionally, extant literature shows conflicting results about...

Background Extinction-based procedures are often used to inhibit maladaptive fear responses. However, because extinction procedures show efficacy limitations, transcranial direct current stimulation (tDCS) has been suggested as a promising add-on enhancer. Objective In this study, we tested how cathodal tDCS over the right dorsolateral prefrontal...
Article
Background Transcranial direct current stimulation (tDCS) has been studied as an add-on enhancer of extinction-based treatments for anxiety disorders. Previous studies have showed that although anodal tDCS enhances fear extinction it also leads to decreased stimuli discrimination and consequent generalization of the fear response. Here we aim to un...

Background Extinction-based procedures are used to inhibit maladaptive fear responses. However, due to extinction efficacy limitations, transcranial direct current stimulation (tDCS) has been studied as a promising add-on enhancer. Previous fundamental research found anodal tDCS to have an adverse effect in increasing generalization of the fear res...

Anxiety sensitivity (AS; the degree of fear of experiencing or imagining experiencing anxiety symptoms and its possible consequences) is associated with expression of conditioned fear responses. However, findings regarding the relationship between AS and fear acquisition indexed by skin conductance responses are rather conflicting. Here we aim to c...

Extinction-based procedures are often used to inhibit maladaptive fear responses. However, because extinction procedures show efficacy limitations, transcranial direct current stimulation (tDCS) has been suggested as a promising add-on enhancer. In this study, we tested the effect of cathodal tDCS over extinction, to unveil the processes at play th...

An integrant part of the Clinical Interview for Psychotic Disorders (CIPD), the EWPSS is a visual analog scale in which the...
Conference Paper
Background Suicide risk is an important variable to consider both in assessment and throughout the therapeutic process in psychotic disorders. The SRS-P is an 18-item scale computed from the patient and clinician-rated scores obtained in the CIPD. The scale comprises lifetime assessment of depressed mood, anhedonia and its current interference and...
