Publication Measuring school social climate in Latin America: the need for multidimensional and multi-informant tests – A systematic review(2023) Bravo-Sanzana, Mónica V.; Varela, Jorge; Oscar Terán-Mendoza, Oscar; Rodríguez-Rivas, Matías E.Introduction: School social climate is central to understanding learning experiences in education environments. Previous studies describe various conceptual and operational definitions around the construct; however, there are no records of reviews focused on Latin America. Aim: This study sought to analyze the available evidence and the quality of school social climate measures in Latin America through a systematic review of the literature based on the PRISMA methodology and the COSMIN checklist to assess the psychometric properties of the instruments. Methodology: The Web of Science, Scopus, Psycinfo, and SciELO databases were consulted. A total of 582 records was identified, of which 27 fulfilled the inclusion criteria and methodological quality to be included in the systematization. Results: The results show that the country with the greatest scientific production on the topic is Chile, the measures are centered mainly on the students’ perspective and the most used instrument is the CECSCE. In addition, a common aspect to all the records is that they were not sufficient to capture the complexity of school social climate. Conclusion: Multidimensional and multi-informant measures are needed to adequately assess the construct.Publication Wellbeing, social media addiction and coping strategies among Chilean adolescents during the pandemic(2023) Varela, Jorge; Pérez, J. Carola; Rodríguez-Rivas, Matías E.; Chuecas, María Josefina; Romo, JavieraIntroduction: During the COVID-19 pandemic, adolescents had to deal with a range of mental health problems that has increased social media addiction levels with adverse effects on life satisfaction. Previous studies have explored coping mechanisms to deal with this addiction problem, but did not consider the need to simultaneously cope with different dimensions. Therefore, our study aimed to examine the moderating effect of various coping mechanisms on the relationship between social media addiction and adolescent life satisfaction. Methods: Self-report questionnaires were applied to 1290 secondary school students (age mean = 16.03, SD = 1.27, range: 14 to 19; and 57% female). An exploratory and a confirmatory factor analysis were performed to determine the factor structure of the Brief-Cope 28 scale. Then, a descriptive and correlational analysis of the variables and a multiple linear regression analysis was performed. Results: We found that the social media addiction risk was negatively associated with life satisfaction, adaptive strategies were positively correlated to life satisfaction, and maladaptive strategies were negatively correlated to it. Also, a moderation model was evaluated in which four stress management strategies, namely acceptance and perspective-taking, seeking socio-emotional support, active coping, and maladaptive strategies all conditioned the relationship between social media addiction risk and life satisfaction after controlling for demographic variables and the specific strategies of using comedy, religion and substance use. Results indicate additive and multiplicative effects of management strategies for stressful situations in the studied relationship. Seeking socio-emotional support and active coping were positively related to life satisfaction and maladaptive strategies were negatively associated with it. Multiplicative effects indicate that the relationship between the social media addiction risk and life satisfaction depends only on the acceptance and perspective taking that adolescents report. When adolescents reported having low or average levels of acceptance and perspective taking, there was a negative correlation with general life satisfaction, a connection that grew markedly stronger. In contrast, no connection between social media addiction and life satisfaction was detected for adolescents who report higher levels of acceptance and perspective-taking. Discussion: Abuse of social media and the use of maladaptive stress coping strategies were risk factors that decreased life satisfaction among adolescents during the COVID-19 pandemic period.Publication Satisfacción usuaria en psiquiatría : niveles y factores asociados(2023) Bolados-Avila, Mónica; Fuentes Olavarría, Daniela; Rodríguez-Rivas, Matías E.Objetivo principal: Determinar los niveles de satisfacción usuaria y sus factores asociados, en una unidad hospitalaria psiquiátrica en Chile.Metodología: Participa-ron 479personas,con un promedio de 37,5 años (44,9% mujeres).Se utilizó estadística descriptiva y un modelo de regresión lineal múltiple.Resultados principales : El promedio de satisfacción usuaria fue de6,53(rango 1 a7). Se determinó que los factores asociados fueron la información entregada al paciente(p= 0,003), el acceso telefónico con familiares(p= 0,016), el uso del tiempo libreen la unidad(p< 0,001), la atención del personal de enfermería (p= 0,001), técnicos paramédicos (p=0,003) y del personal médico (p= 0,01). Dentro de la infraestructura, solo la valoración de espacios comunes de la unidad fue significativa (p= 0,049). Conclusión principal: El nivel de satisfacción fue alto y sus factores se relacionan principalmente con la gestión del cuidado de enfermería.Publication Reducing stigma toward people with serious mental illness through a virtual reality intervention: a randomized controlled trial(2023) Rodríguez-Rivas, Matías E.; Cangas, Adolfo J.; Martín, Andrés; Romo, Javiera; Pérez, J. Carola; Valdebenito, Sara; Cariola, Laura; Onetto, Josefina; Hernández, Bárbara; Ceric Garrido, Francisco; CEA GONZÁLEZ, PABLO ANTONIO; Corrigan, PatrickBackground: Stigma toward people with serious mental illnesses (SMI), like schizophrenia, is a serious global public health challenge that limits the quality of life of those affected and poses a major barrier that keeps people from seeking professional help. There is an urgent need for novel, effective, and scalable interventions to decrease stigmatized perceptions of chronic psychotic disorders and to reduce the health burden imposed by them. Method: We conducted a randomized controlled trial to assess the impact of a new immersive virtual reality game (Inclúyete-VR) on the level of stigma toward people with SMI, measured by the AQ-27 Attribution Questionnaire. Participants in the experimental group were exposed in an immersive way to hallucinations common in schizophrenia, then shown different psychosocial resources available for their recovery and social inclusion; those in the control group used VR software unrelated to mental health. VR sessions were delivered through Oculus headgear and lasted 25 minutes. Results: We randomly assigned 124 university students (55% female) to experimental or control conditions (n=62 each). We used mixed ANOVA to compare outcomes before and after the intervention between the two groups. We found a significant intervention-by-time interaction (p<0.001), with a reduction in the experimental group of overall stigma levels on the AQ-27 scale and its three subscales: dangerousness-fear, avoidance, and lack of solidarity (p<0.001 for all). Conclusions: The Inclúyete-VR software proved effective in the short term in reducing stigma toward people with severe mental illness. The program’s longer-term efficacy, scalability, and dissemination remain to be studied.Publication Technology-Based Interventions for Promoting Well-Being in Childhood and Adolescence: A Systematic Review and Meta-Analysis(2025) Rodríguez-Rivas, Matías E.; Valdebenito, Sara; Benavente, Mariavictoria; Alfaro Inzunza, Jaime; Villacura, Paula; Chuecas, María Josefina; Ditzel, Ana Loreto; Galdames, AlejandraBackground: Well-being is crucial for children’s and adolescents’ mental health. Despite numerous interventions, innovative technological options are still underexplored, particularly for younger populations. This study aims to review, summarize, and discuss experimental studies on the effects of technological interventions on well-being in childhood and adolescence. Method: We conducted a systematic review and meta-analysis following PRISMA guidelines, including studies published since 2013. Searches were conducted in PubMed, PsycInfo, Scopus, and Web of Science including randomized and non-randomized controlled trials. The quality of studies was assessed using the Cochrane Risk of Bias (ROB-2) and ROBINS-I tools. Meta-analyses were performed using R studio. Results: Of the 2705 articles screened by title and abstract, 55 underwent full-text review. Seventeen articles were included, showing a diversity of technology-based interventions, including apps, web-based intervention, digital intervention, and chatbots. The meta-analysis (n = 5636 participants) showed a small but statistically significant effect in promoting well-being (Hedges’s g = 0.18; p < .01). App-based interventions demonstrated a notably larger effect size (Hedges’s g = 0.33; p < .001). Conclusions: The findings highlight a range of technological interventions for promoting well-being in children and adolescents, with apps showing greater effectiveness. This supports their use as valuable resources for this population.
