Body illusions could serve as valuable tools to identify individuals who are most likely to benefit from therapies due to their heightened body-image flexibility. However, little is known about the association between body-image flexibility and key psychological factors related to eating disorder (ED) symptomatology such as hypersensitivity and def...

Individuals with subthreshold symptoms of Eating Disorders (ED) present problems in integrating auditory signals related to body weight into their body. However, it remains unclear whether these impairments are specific to auditory bodily signals or if they extend to other auditory signals. Here we investigated the "auditory Pinocchio illusion," wh...

Individuals with subthreshold Eating Disorder (ED) symptomatology and anorexia nervosa experience difficulties in integrating auditory-signals related to body weight into their body perception. However, it is unclear whether these impairments are specific to auditory bodily signals or extend to any auditory signals. We used the "auditory Pinocchio...

The factor structure of the MBSRQ is under debate due to the limitations of previous research methods such as principal component analysis (PCA). Although the four-dimensional 38-item version of the MBSRQ is widely used in Spain, recent studies suggest a more efficient two-factor 15-version item. However, no studies have directly compared both vers...

Background Bodily illusions can be used to investigate the experience of being in a body by manipulating the underlying processes of multisensory integration. Research suggests that people with eating disorders (EDs) may have impairments in visual, interoceptive, proprioceptive, and tactile bodily perception. Furthermore, people with EDs also show...

Background Experimental research based on bodily illusions suggests that people with eating disorders (EDs) might have impairments in visual, interoceptive, proprioceptive, and tactile perception, potentially underpinning altered multisensory integration processes. Along this line, research indicates that people with EDs show abnormalities in integ...

Background: Many technological interventions designed to promote physical activity (PA) have limited efficacy and appear to lack important factors that could increase engagement. This may be due to a discrepancy between research conducted in this space, and software designers' and developers' use of this research to inform new digital applications...

The aim of this research was to study the mediation of motivational regulations on the relationship between body image and physical activity (Preliminary Work)

Background Recent research indicates that patients with anorexia (AN) show specific eye movement abnormalities such as shorter prosaccade latencies, more saccade inhibition errors, and increased rate of saccadic intrusions compared to participants without AN. However, it remains unknown whether these abnormal eye movement patterns, which may serve...

Background: Recent research indicates that patients with anorexia (AN) show specific eye movement abnormalities such as shorter prosaccade latencies, more saccade inhibition errors, and increased rate of saccadic intrusions compared to participants without AN. However, it remains unknown whether these abnormal eye movement patterns, which may serve...

Background: Recent research indicates that patients with eating disorders (ED) show specific eye-movement abnormalities namely square wave jerks (SWJs), which are involuntary, sporadic, horizontal, saccadic intrusions that interrupt fixation. As such, SWJs have the possibility to serve as potential biomarkers for an early diagnosis of EDs and preve...

Purpose: Previous research reported adequate psychometric properties of the BQPA, which was developed based on barriers detected in the overweight population. To increase its generalizability, to the general population, the BQPA was revised based on a non-restricted literature review (BQPA-G). This study analyses the reliability, factor structure a...

1.-Introduction: AN are among the mental illnesses with the highest mortality rates and the worst therapeutic outcomes. Earlier treatment response is essential to later symptom remission. Eye-tracking studies show that AN is linked to specific eye movement patterns (shorter latencies or larger inhibitory errors, e.g., Phillipou, et al., 2016), bein...

Introduction: Physical activity (PA) has significant health benefits. However, a third of the adult population across Europe is physically inactive and numbers are on the rise. To address this problem, a large body of the literature has tried to identify the variables influencing the adherence to PA (barriers or facilitators). Consequently, it is k...

Dual pathology is often found in addiction and mental health centers. Although there are integrated services for these patients, most countries have developed joint action protocols between addiction and mental health centers. The objective is to analyze the progress of patients diagnosed with dual pathology, comparing the therapeutic outcomes of t...

Objective: This study aimed to develop the BQPA and evaluate its psychometric properties, which covers all the relevant barriers for Physical Activity (PA) reported in the literature. Method/Design: A cross-sectional study was performed in 2019 through a dedicated online panel. A sample of 610 participants was selected using a stratified random sam...

BACKGROUND Physical inactivity is a main risk factor of death worldwide, and contributes to psychological and physical problems, including obesity. Physical activity (PA) is critical to preventing health deterioration. Many technological interventions designed to promote PA have limited efficacy as some critical variables affecting PA are not consi...

Dual patients are usually treated in drug users services, mental health units, or both. However, each patient can choose the service to receive the health care. The aim of this study is to analyze the similarities and differences of the patient profiles that are treated in each one of these centers. The sample consists of 170 patients diagnosed wit...

The aim of this study was to analyze and compare the profile of dual patients treated in mental health units or drug user services with patients using both. The sample consisted of 170 patients diagnosed with dual pathology, recruited using an accidental sampling technique. Of the sample, 64 were being treated at Addiction Center of Huelva (ADH), 5...
