The pressure that coaches usually apply on their athletes, alongside injuries and the lack of enjoyment during sport practice, are key factors involved in sports abandonment. Behavioral interventions through psychoeducational programs have proven to be useful to improve coaching behaviors, providing appropriate context in sports. This study aims to...

Growing evidence supports the hypothesis that temperamental traits are not static throughout adolescence. The known links between both reactive and regulatory temperament and anxiety symptoms should be investigated bearing this hypothesis in mind. This study collected self-reported data on behavioral inhibition system (BIS) sensitivity, attentional...

Smartphone applications (apps) improve accessibility to smoking cessation treatments. The NoFumo+ app administers a Cognitive Behavioral Therapy program for smoking cessation. This study evaluates the efficacy of NoFumo+ for quitting smoking or reducing cigarette consumption versus the usual information-based treatment. A clinical trial was conduct...

The risk of suffering anxiety disorders is associated with sustained subthreshold symptoms of anxiety. This study evaluated the stability of anxiety scores (high, moderate or low) across a six-month period in early adolescents (N = 95). The associations between sustained anxiety, vagally-mediated heart rate variability (vmHRV), sympathetic activity...

Maladaptive patterns of cardiac adjustment to stress in adolescents may reveal their vulnerability to anxiety disorders (ADs). Traditional research in this field has focused on anxiety levels, whereas the time course of anxiety has rarely been considered. Nevertheless, since overall anxiety decreases as adolescence progresses, increasing time cours...

This study analyses participants’ preferences regarding three computeraided exposure treatments for fear of flying (FF): virtual reality exposure treatment assisted by a therapist (VRET), computer-aided exposure with a therapist present throughout exposure sessions (CAE-T), and self-administered computer-aided exposure (CAE-SA). Sixty participants...

Nonlinear measures can capture the complex structure of the heart beating, and recordings taken while the individual performs daily activities may help to understand the cardiac system's output in natural conditions. As healthy systems are characterized by having highly complex outputs, we hypothesized that the cardiac output from high anxious adol...

The aim of this paper is to introduce the TrANS Project and the first results obtained from two studies. This Project allows to examine trajectories of anxiety symptoms and state anxiety in adolescents by means of ICT, in particular a secure social network for data collection. Study 1 describes the structure and functioning of the secure social net...

Variability in both frontal and parietal spontaneous EEG activity, using α and β band power and θ/β and δ/β ratios, was explored in a sample of 96 healthy volunteers as a potential correlate of individual differences in spontaneous emotion regulation (SER). Following a baseline EEG recording, participants were asked to continuously rate their disco...

Attentional network functioning in emotionally neutral conditions and self-reported attentional control (AC) were analysed as predictors of the tendency to engage in dysfunctional emotion regulation strategies. Diminished attentional orienting predicted an increased tendency to engage in brooding rumination, and enhanced alertness predicted a great...

The goals of this study were (a) to examine the psychometric properties of a Catalan version of the Effortful control scale of the Adult Temperament Questionnaire short-form and (b) to analyze the relationships among effortful control (EC), negative affectivity (NA), and the use of negative cognitive emotion regulation (ER) strategies. In a sample...

Effective regulation of emotions requires the ability to voluntarily manage attention, i.e. attentional control (AC), which has been related to heart rate variability and vagal tone in laboratory based research. In this study, we calculated the correlation dimension (CD), the fractal-like properties (scaling exponents ?1 and ?2, and fractal dimensi...

The present study explores both resting cortical EEG asymmetry and vagally-mediated heart rate variability (HRV), as an index for vagal tone, as physiological correlates of self-reported attentional control in a sample of 53 healthy young adults. Regression analyses indicate that higher vagally-mediated HRV and lower right-sided parietal activity i...

Several studies have reported differences in long-range temporal correlations of EEG oscillations between depressed and nondepressed individuals. The question remains unsolved whether these differences are also linked to negative emotion regulation strategies that configure a depressive style. In this study we applied detrended fluctuation analysis...

Introduction: The interplay of reactive and regulatory temperamental processes appears to be essential for a better understanding of emotional states and disorders. In this study we explored the prospective relationship between reactive temperament (negative affect), regulatory temperament (effortful control), negative emotion regulation styles (r...

The cognitive regulation of emotions is important for human adaptation. Self-focused emotion regulation (ER) strategies have been linked to the development and persistence of anxiety and depression. A vast array of research has provided valuable knowledge about the neural correlates of the use of specific self-focused ER strategies; however, the re...

The goal of this study was to explore why certain patients in a previous study on exposure therapy for flight phobia did not experience an improvement in their conditions. Participants from a treatment study (N = 45) were selected according to post-treatment results and divided into two groups: the unsatisfactory treatment outcome group (UTO, N = 1...

This study tested the hypothesis that flight-phobic patients experience change at different rates even when they are receiving identical treatment. Faster within-session rates of change (WSRC) were expected for patients who required fewer exposure sessions. The study also tested the theoretical role of autonomic flexibility on WSRC. High flexibilit...

Evidence is growing that two modalities of computer-based exposure therapies--virtual reality and computer-aided psychotherapy--are effective in treating anxiety disorders, including fear of flying. However, they have not yet been directly compared. The aim of this study was to analyze the efficacy of three computer-based exposure treatments for fe...

The aim of our study was to characterize brain dynamics of affective modulation of somatosensory processing in chronic pain. We hypothesized that chronic pain patients will show abnormal EEG activity under negative mood conditions compared to healthy controls. Nineteen patients with chronic pain and 21 healthy subjects participated in the experimen...

En este estudio de caso único se registró la actividad electroencefalográfica (EEG) de una paciente fóbica a las serpientes una semana antes del tratamiento, una semana después de una exitosa terapia de exposición en una sesión y un año después. El EEG se obtuvo en situación de reposo y durante la presentación de imágenes de serpientes, imágenes co...

Phylogenetic fears involve stimuli representing a real or potential threat to the species¿ evolutionary ancestors. We tested whether individuals with a phylogenetic fear (spider phobics, n = 17) differed in EEG general activity (delta band power) of the oldest brain system and in complexity from individuals with a non-phylogenetic fear (flight phob...

This review introduces the state of the art in computer-assisted treatment for behavioural disorders. The core of the paper is devoted to describe one of these interventions providing computer-assisted exposure for flight phobia treatment, the Computer-Assisted Fear of Flying Treatment (CAFFT). The rationale, contents and structure of the CAFFT are...

In the present study a computer-assisted exposure-based treatment was applied to 54 flight phobics and the predictive role of vagally mediated heart rate (HR) variability (high frequency, 0.15-0.4 Hz band power) and heart rate entropy (HR time series sample entropy) on treatment outcome was investigated. Both physiological measures were taken under...

This quasi-experimental study analyzes the compared effectiveness of two teaching metholodologies, one based on seminars with frequent testing (group S), and the other based on lectures and a single final exam (group M) and students' commitment and willingness to follow these teaching methodologies in a course on Behaviour Therapy included in the P...

A dia d’avui les TIC segueixen sense formar part de la realitat quotidiana dels centres educatius, i ara l’excusa no pot ser només la manca d’ordinadors. Per què no s’usen les TIC a les aules? Per què s’haurien d’utilitzar? Com s’hauria de fer? L’objectiu d’aquestes línies és reflexionar, des d’una perspectiva pràctica, sobre les possibles resposte...

In this study we explored the changes in the variability and complexity of the electrocardiogram (ECG) of flight phobics (N=61) and a matched non-phobic control group (N=58) when they performed a paced breathing task and were exposed to flight related stimuli. Lower complexity/entropy values were expected in phobics as compared to controls. The pho...

En este estudio se analizan los cambios en la variabilidad de la tasa cardíaca (HRV) relacionada con el sistema vagal en sujetos fóbicos durante la exposición a estímulos temidos. Se ha introducido una tarea de respiración pautada para controlar los efectos de la misma en la medida de la HRV. Han participado en el estudio 61 pacientes con fobia a v...

Research within the framework of the nonlinear dynamical systems (NDS) in the field of anxiety disorders has shown that greater irregularity/complexity appears in the output from healthy systems. In this study we measured the Heart rate variability (HRV) and the sample sntropy (SampEn) of the ECG mV time series of fearful flyers (N = 15) and a matc...

Computer-assisted treatments have proven to be effective in the treatment of several anxiety disorders and depression, but the role of exposure remains unclear. This study compares the efficacy of a computer-assisted exposure treatment (CAE) with a brief multicomponent nonexposure treatment (MNE) for flight phobia. Outcome measure assessments were...

The aim of this experiment was to explore changes in the vagally mediated heart rate variability (HRV) of flight phobics during exposure to feared stimuli. A paced breathing task was included to control for respiration effects. Sixty-one flight phobics (40 women) with a mean age of 39.07 years (SD = 11.24) participated in the study. The root mean o...

Previous research has shown that phobic subjects with low heart rate variability (HRV) are less able to inhibit an inappropriate response when confronted with threatening words compared to phobic subjects with high HRV [Johnsen, B.H., Thayer, J.F., Laberg, J.C., Wormnes, B., Raadal, M., Skaret, E., et al., 2003. Attentional and physiological charac...

Chaos theory provides a new way to analyze the psychophysiological functioning of anxiety disordered people. However, in order to apply any of the nonlinear analysis techniques, nonlinearity tests must be performed and nonlinearity must be found in the psychophysiological signal. In this experimental study we use the surrogate data method to analyz...

La Teoría del Caos proporciona una nueva forma de analizar las respuestas psicofisiológicas asociadas a los trastornos de ansiedad. Pero para poder aplicar los métodos de análisis no lineal de esta relativamente reciente teoría, primero es necesario comprobar la existencia de algún tipo de no linealidad que justifique su uso. En este estudio experi...

In the present study, the relationship between self-implication during simulated exposure to feared stimuli and Heart Rate Variability (HRV) was explored within the framework of the dynamical systems model of emotion regulation proposed by Thayer and Lane (Thayer, J.F., and Lane, R.D. (2000). A model of neurovisceral integration in emotion regulati...
