Around 25,000 war veterans in Portugal suffer posttraumatic stress disorder (PTSD). This clinically controlled study evaluates virtual reality exposure therapy (VRET) as an alternative procedure to reduce PTSD symptoms. Ten patients were assigned to three groups: VRET, exposure in imagination (EI), and waiting list (WL). The patients were Portuguese veterans from a series of wars fought in former African colonies more than 30 years ago. While the EI group participated in traditional imagination therapy, the VRET group was exposed to a virtual reality (VR) war scenario. Cues such as ambush, mortar blasting, and waiting for rescue were used in the VR. Patients enrolled in the VRET group showed statistical reduction of PTSD-associated disorders like depression and anxiety. Far from being conclusive, this pilot study nonetheless presents some promising data on the use of VRET on old war veteran populations.

Immersive virtual reality is thought to be advantageous by leading to higher levels of presence. However, and despite users getting actively involved in immersive three-dimensional virtual environments that incorporate sound and motion, there are individual factors, such as age, video game knowledge, and the predisposition to immersion, that may be associated with the quality of virtual reality experience. Moreover, one particular concern for users engaged in immersive virtual reality environments (VRE s ) is the possibility of side effects, such as cybersickness. The literature suggests that at least 60% of virtual reality users report having felt symptoms of cybersickness, which reduces the quality of the virtual reality experience. The aim of this study was thus to profile the right user to be involved in a VRE through head-mounted display. To examine which user characteristics are associated with the most effective virtual reality experience (lower cybersickness), a multiple correspondence analysis combined with cluster analysis technique was performed. Results revealed three distinct profiles, showing that the PC gamer profile is more associated with higher levels of virtual reality effectiveness, that is, higher predisposition to be immersed and reduced cybersickness symptoms in the VRE than console gamer and nongamer. These findings can be a useful orientation in clinical practice and future research as they help identify which users are more predisposed to benefit from immersive VRE s .

Craving is a strong desire to consume that emerges in every case of substance addiction. Previous studies have shown that eliciting craving with an exposure cues protocol can be a useful option for the treatment of nicotine dependence. Thus, the main goal of this study was to develop a virtual platform in order to induce craving in smokers. Fifty-five undergraduate students were randomly assigned to two different virtual environments: high arousal contextual cues and low arousal contextual cues scenarios (17 smokers with low nicotine dependency were excluded). An eye-tracker system was used to evaluate attention toward these cues. Eye fixation on smoking-related cues differed between smokers and nonsmokers, indicating that smokers focused more often on smoking-related cues than nonsmokers. Self-reports of craving are in agreement with these results and suggest a significant increase in craving after exposure to smoking cues. In sum, these data support the use of virtual environments for eliciting craving.

Introduction: Pregnancy is characterized by physical, hormonal, and psychological changes that can affect women’s sexuality, and, for those who are in a dyadic relationship, it also affects the couple’s sexual relationship. On the other hand, the pregnancy state can function as a protective factor for body dissatisfaction as women embrace a new phase of the life cycle when body changes, namely more body volume, are expected. Aim: To examine whether the effect of body dissatisfaction on sexual distress is mediated by cognitive distraction with the appearance of the body and to test a moderated mediation model of the impact of body dissatisfaction on sexual distress, with pregnancy used as the moderating factor. Methods: In this cross-sectional study, 87 cisgender heterosexual women (50.6% pregnant; n = 44), aged between 25 and 40 years old (mean = 31.93; SD = 3.46) involved in an exclusive and committed dyadic relationship completed a web-based questionnaire. Main Outcome Measures: Validated measures consisted of a validated general measure of body dissatisfaction (global body dissatisfaction scale), sexual distress (adapted from the National Survey of Sexual Attitudes and Lifestyles), and cognitive distraction based on body appearance during sexual activity (body appearance cognitive distraction scale). Results: Results indicated that body dissatisfaction and sexual distress are related, but they are fully mediated by cognitive distraction. The mediation effect of cognitive distraction did not differ significantly by pregnancy status, after controlling for the trimester of pregnancy. Clinical Implications: This study advances our understanding of sexuality during pregnancy by evaluating sexual distress and establishing that it is a clinically relevant variable related to body dissatisfaction that deserves attention from healthcare providers. Strength & Limitations: This preliminary study uses a robust method of data analysis to test a theory-based cognitive model of sexual distress in pregnant women; however, no causality can be established. Conclusion: The data highlights that pregnancy may not be a protective factor for the impact of body dissatisfaction on sexual distress.
