Psychometric Analysis of the Barber Suggestibility Scale in a Clinical Population.

The aim of the study was to administer the Barber suggestibility scale to a clinical population in Spain and to examine its psychometric properties therein. The reliability and factor structure of the adapted scale was compared with that of the original (American) scale and with data from two other versions (British and Puerto Rican samples). Sex differences in suggestibility were also analyzed.

Peer counselling versus role-playing: Two training methods of therapeutic skills in clinical psychology.

Background: Training programmes for clinical psychologists should include evidence-based teaching methods that enable trainees to learn therapeutic skills. Here we compared the perceived utility of role-playing vs. peer counselling.

Trait and State Craving as Indicators of Validity of VR-based Software for Binge Eating Treatment.

The aim of this study was to establish whether virtual reality (VR) exposure to food cues is able to produce craving levels consistent with state-craving and trait-craving as assessed by the Spanish and Italian versions of the State and Trait Food Craving Questionnaires (FCQ-T/S). The results were compared in 40 patients with eating disorders (17 with binge eating disorder, 23 with bulimia nervosa) and 78 healthy control subjects without eating disorders. Controls and patients with higher levels of trait-craving and state-craving both showed a greater desire to eat during VR exposure.

External Eating as a Predictor of Cue-reactivity to Food-related Virtual Environments.

The objective of this study was to assess the association between external eating style and food craving experienced during exposure to food cues in virtual reality (VR) environments in both clinical and non-clinical samples. According to the externality theory, people with external eating experience higher reactivity when exposed to food cues, which in turn increases the probability of overeating. Forty patients with eating disorders (23 with bulimia nervosa and 17 with binge eating disorder) and 78 undergraduate students were exposed to 10 different food cues in four VR environments (kitchen, dining room, bedroom, and café).

Differential effects of two virtual reality interventions: distraction versus pain control.

There is evidence that virtual reality (VR) pain distraction is effective at improving pain-related outcomes. However, more research is needed to investigate VR environments with other pain-related goals. The main aim of this study was to compare the differential effects of two VR environments on a set of pain-related and cognitive variables during a cold pressor experiment.
