Virtual and Augmented Reality: New Frontiers for Clinical Psychology

In the last decades, the applied approach for the use of virtual reality (VR) and augmented reality (AR) on clinical and health psychology has grown exponentially. These technologies have been used to treat several mental disorders, for example, phobias, stress-related disorders, depression, eating disorders, and chronic pain. The importance of VR/AR for the mental health field comes from three main concepts: (1) VR/AR as an imaginal technology, people can feel “as if they are” in a reality that does not exist in external world; (2) VR/AR as an embodied technology, the experience to feel user’s body inside the virtual environment; and (3) VR/AR as connectivity technology, the “end of geography’. In this chapter, we explore the opportunities provided by VR/AR as technologies to improve people’s quality of life and to discuss new frontiers for their application in mental health and psychological well-being promotion

What is the Current and Future Status of Digital Mental Health Interventions?

The prevalence of mental disorders continues to increase, especially with the advent of the COVID-19 pandemic. Although we have evidence-based psychological treatments to address these conditions, most people encounter some barriers to receiving this help (e.g., stigma, geographical or time limitations). Digital mental health interventions (e.g., Internet-based interventions, smartphone apps, mixed realities -virtual and augmented reality) provide an opportunity to improve accessibility to these treatments. This article summarizes the main contributions of the different types of digital mental health solutions. It analyzes their limitations (e.g., drop-out rates, lack of engagement, lack of personalization, lack of cultural adaptations) and showcases the latest sophisticated and innovative technological advances under the umbrella of precision medicine (e.g., digital phenotyping, chatbots, or conversational agents). Finally, future challenges related to the need for real world implementation of these interventions, the use of predictive methodology, and hybrid models of care in clinical practice, among others, are discussed

The Binge Eating Scale: Structural Equation Competitive Models, Invariance Measurement Between Sexes, and Relationships With Food Addiction, Impulsivity, Binge Drinking, and Body Mass Index

Introduction: The Binge Eating Scale (BES) is a widely used self-report questionnaire to identify compulsive eaters. However, research on the dimensions and psychometric properties of the BES is limited.Objective: The aim of this study was to examine the properties of the Spanish version of the BES.Methods: Confirmatory Factor Analyses (CFAs) were carried out to verify the BES factor structure in a sample of Spanish college students (N = 428, 75.7% women; age range = 18–30). An invariance measurement routine was carried out across sexes, the latent means were compared, and estimates of reliability and convergent and discriminant validity were presented.Results: A one-factor model fit the data best and was also equivalent between sexes. The scalar invariance model showed statistically significant differences across sexes, with a higher prevalence in women. Regarding reliability, the results were excellent. Finally, high statistically significant correlations were obtained with other measures of binge eating (BE), food addiction, impulsivity, binge drinking, and body mass index (BMI).Conclusion: The Spanish 16-item BES is a valid and reliable scale to evaluate BE in the youth population

Qualitative analysis of the best possible self intervention: underlying mechanisms that influence its efficacy

Background The Best Possible Self is a Positive Psychology Intervention which asks participants to write down about themselves in their best possible future. Previous studies have shown its efficacy to enhance wellbeing, but the mechanisms that underlie its efficacy are still unknown. Objective The aim of this study was to analyze the content of the essays of the BPS intervention and to examine how this content was related to the efficacy of the intervention to increase positive affect. Method Participants (N = 78) were randomized to either the Best Possible Self condition, or one of two variants of the intervention: one''s best self in the present, and one''s best self in the past. Qualitative analyses of the texts were carried out to explore the main themes and features of the essays. Then, a mixed-methods approach with quantitative and qualitative data was followed, in order to analyze the relationship between the content of the texts and the change in positive affect produced by the interventions. Results Significant differences between conditions were found in the content of the compositions. Regression analyses showed that different variables predicted the change in positive affect depending on the condition. Mediation analyses also found differences among conditions. Conclusions These findings suggest that these interventions respond to different underlying mechanisms which influence their efficacy. This study contributed to a better understanding of how Positive Psychology Interventions work, and how to increment their efficacy

Psychological intervention using virtual reality for patients with cancer.

El objetivo de este trabajo es presentar las principales aportaciones de la Realidad Virtual (RV) en el tratamiento psicológico con pacientes oncológicos, y describir un programa de intervención que utiliza esta tecnología para promover bienestar emocional en pacientes hospitalizados. La RV se presenta como una prometedora herramienta de apoyo al paciente oncológico. Diversos estudios plantean su utilidad para hacer algunos tratamientos médicos más tolerables, para reducir los niveles de distrés y dolor, así como promover mayores niveles de emociones positivas. Se ha empleado principalmente con pacientes ambulatorios, existiendo una menor proporción de propuestas dirigidas al período de hospitalización. La intervención que ha desarrollado nuestro grupo aborda esta condición desde un foco también poco explorado: la promoción de bienestar. Esta intervención se compone de 4 sesiones (módulos de distracción y reminiscencia) implementadas individualmente en la habitación del paciente. Antes y después de cada sesión se evaluó el estado emocional (escalas visuales), la percepción de paso del tiempo (en minutos), de cambio en el estado de ánimo y de satisfacción con el procedimiento. Los resultados iniciales señalan incrementos en las emociones positivas después de cada sesión, existiendo cambios significativos en la primera y tercera sesión. Además, la mayoría de pacientes informó que su estado de ánimo había mejorado después de las sesiones. A partir de estos hallazgos se observa que los entornos virtuales y las tecnologías de la información y la comunicación muestran utilidad no sólo para disminuir el malestar sino también para promover bienestar emocional, especialmente durante períodos de tratamiento y hospitalización.The purpose of the present study is to review the main contributions of Virtual Reality (VR) to the field of psychological treatment with cancer patients, and to describe an intervention that uses this technology to promote emotional well-being on inpatients. VR appears as a promising tool for supporting psychological treatments in cancer patients. Several studies explore its utility for promoting more tolerable medical treatments, lowering the level of distress and pain, as well as increasing positive emotions. VR has been mainly used with outpatients, with a minor proportion of proposals oriented to the hospitalization period. The intervention developed by our group addresses this issue from a focus not very much explored: the promotion of well-being. This intervention is composed of 4 sessions (distraction and reminiscence modules) implemented individually in the patients’ room. Emotional state (visual analog scales), perceived time duration (minutes), perception of mood change and satisfaction with the procedure were assessed before and after sessions. Preliminary results showed an increase in positive emotions after each session, being these changes significant in the first and third session. Besides, most patients perceived themselves in a better mood after the sessions. Virtual environments and information and communication technologies could be useful not only to diminish discomfort but also to promote emotional well-being, especially during medical procedures and hospitalizatio

Manipulating Self-Avatar Body Dimensions in Virtual Worlds to Complement an Internet-Delivered Intervention to Increase Physical Activity in Overweight Women

[EN] Virtual reality has been found to be a useful tool for positively influencing relevant psychological variables in order to increase physical activity (PA), especially in the overweight population. This study investigates the use of avatars and their physical variations to extend the effectiveness of existing interventions to promote PA. The main objective is to analyze the influence of the avatars' body dimensions on the efficacy of an Internet intervention to increase PA levels and improve other relevant variables (motivation toward PA, enjoyment, anxiety, self-efficacy, and PA goals). A total of 42 overweight women received a brief online intervention, and they were randomly assigned to one of three conditions: the "Ideal avatar" (IAC: participants are represented by avatars with ideal body dimensions); the "Real avatar" (RAC: participants are represented by avatars with participants' current body dimensions); and the "Non avatar" (NAC: participants are not represented by avatars). Results showed that the online intervention was effective in increasing PA practice and self-efficacy expectations. However, manipulating the body dimensions of avatars did not improve this intervention, although ideal avatars helped to reduce the anxiety experienced during PA in this population.This study was funded by "INTERSABIAS" project (PROMETEO/2018/110, Conselleria d'Educacion, Investigacio, Cultura i Esport de la Generalitat Valenciana) and by CIBER of Physiopathology of Obesity Nutrition, an initiative of ISCII (ISCII CB0603/0052).Navarro, J.; Cebolla, A.; Llorens Rodríguez, R.; Borrego, A.; Baños, RM.

How the COVID-19 pandemic and its consequences affect the presence of and search for meaning of life: a longitudinal study

The presence of meaning in life (PML) and the search for meaning in life (SML) are crucial when facing difficult times. Although several theoretical frameworks have tried to explain the dynamics of meaning in life during adversity, empirical evidence about interactions among both constructs using longitudinal designs is scarce. This study examined the trajectories of both PML and SML during the COVID-19 lockdown period in Spain. In total, 220 adults fulfilled an online survey during two periods: a strict and a relaxed lockdown period. Latent growth models showed that both PML and SML declined slightly during the strict lockdown, but they reached a plateau during the relaxed lockdown. Results also showed that age and having a partner predicted higher PML and lower SML at baseline, whereas being male predicted higher scores on PML. PML and SML were negatively associated at baseline, higher SML at baseline was related to a steeper decreasing PML slope during the strict lockdown, and the PML and SML slopes in the relaxed lockdown period were negatively related. This study contributes to better understanding longitudinal fluctuations of meaning in life in situations of adversity

Perfil psicopatológico de niños con sobrepeso u obesidad en tratamiento de pérdida de peso

The aim of this study was to explore the psychopathological profile of overweight/obese children in treatment for weight loss in a specialized pediatric unit, in comparison with a group of non-overweight/obese children. A sample of 89 children (9 to 16 years-old) was evaluated for the presence of the following psychological variables: depression, anxiety, self-esteem and body satisfaction. The sample consisted of 44 overweight/obese children undergoing weight loss treatment and 45 normal-weight children. Compared to the children with normal weight, the overweight/ obese children presented more body dissatisfaction, lower academic and body self-esteem, and higher levels of anxiety. The variable which best discriminated between the groups was body dissatisfaction. The results support previous studies that have shown the presence of psychopathology in obese children, and the existence of differential psychopathological features.El objetivo de este estudio es explorar el perfil psicopatológico de los niños con obesidad/ sobrepeso que buscan un tratamiento de pérdida de peso en una unidad de pediatría especializada, en comparación con un grupo de niños sin obesidad/sobrepeso. Una muestra de 89 niños (de 9 a 16 años) fueron evaluados en las siguientes variables psicológicas: depresión, ansiedad, autoestima y satisfacción corporal. La muestra estuvo compuesta por 44 niños con obesidad/sobrepeso que estaban en tratamiento de pérdida de peso y 45 niños con peso normal. Comparado con los niños con normopeso, los niños son obesidad/sobrepeso presentaron mayor insatisfacción corporal, baja autoestima académica y corporal, y niveles de ansiedad más altos. La variable que mejor discriminó entre los dos grupos fue la satisfacción corporal. Los resultados apoyan estudios previos que han mostrado que la presencia de psicopatología en niños obesos, y la existencia de características psicopatológicas diferenciales.

Food addiction and its relationship with other eating behaviours among Spanish university students

BackgroundFood addiction (FA) is characterised by symptoms such as loss of control over food consumption, inability to reduce consumption despite the desire to do so, and continued consumption despite negative consequences. The modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) is a widely used instrument to assess FA.ObjectivesTo validate the Spanish mYFAS 2.0; to analyse the relationships between FA with other eating behaviours, sociodemographic variables, and Body Mass Index (BMI); and to test the eating-related variables that account for the variance in FA.MethodsThe sample consisted of 400 university students (M-age = 24.16, SDage = 6.12; 51% female), who completed the mYFAS 2.0 and measures of eating-related constructs.ResultsA confirmatory factor analysis (CFA) supported the one-factor structure of the mYFAS 2.0. The scale showed good internal consistency (alpha = .78), and good convergent validity with the mYFAS. FA was related to eating styles, binge eating, and bulimia. No differences in FA were observed between males and females, and there was no association between FA and BMI. In addition, younger participants scored higher on FA than older participants. The eating-related variables explain 54.7% of the variance in FA.ConclusionsThe mYFAS 2.0 is a valid and reliable scale to assess FA in the Spanish population. The positive and significant relationship of variables related to eating (eating styles, binge eating and bulimia) with FA was demonstrated. These variables were indicated by those at high risk of FA. Plain English summaryFood addiction (FA) is characterised by excessive and dysregulated intake of high-calorie foods. Loss of control over food consumption, inability to reduce consumption, and continued consumption despite negative consequences are some of its symptoms. The modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) is a brief instrument specifically developed to assess FA. The objectives of this study were: (1) to examine the psychometric properties of the Spanish mYFAS 2.0; (2) to analyse the relationships between FA with other eating behaviours, sociodemographic variables, and Body Mass Index (BMI); and (3) to test whether there are certain dietary variables that may be positively related to FA. We were able to provide evidence that the mYFAS 2.0 is a valid and reliable scale for assessing FA in the Spanish population. The positive and significant relationship of eating-related variables (eating styles, binge eating and bulimia) with FA was demonstrated. These variables can be considered to identify subgroups at high risk of FA
