Background: Stigma toward people with mental illness presents serious consequences for the impacted individuals, such as social exclusion and increased difficulties in the recovery process. Recently, several interventions have been developed to mitigate public stigma, based on the use of innovative technologies, such as virtual reality and video games. Objective: This review aims to systematically review, synthesize, measure, and critically discuss experimental studies that measure the effect of technological interventions on stigmatization levels. Methods: This systematic review and meta-analysis was based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines and included studies in English and Spanish published between 2016 and 2021. Searches were run in 5 different databases (ie, PubMed, PsycInfo, Scopus, Cochrane Library, and ScienceDirect). Only randomized controlled trials were included. Two independent reviewers determined the eligibility, extracted data, and rated methodological quality of the studies. Meta-analyses were performed using the Comprehensive Meta-Analysis software. Results: Based on the 1158 articles screened, 72 articles were evaluated as full text, of which 9 were included in the qualitative and quantitative syntheses. A diversity of interventions was observed, including video games, audiovisual simulation of hallucinations, virtual reality, and electronic contact with mental health services users. The meta-analysis (n=1832 participants) demonstrated that these interventions had a consistent medium effect on reducing the level of public stigma (d=–0.64; 95% CI 0.31-0.96; P<.001). Conclusions: Innovative interventions involving the use of technologies are an effective tool in stigma reduction, therefore new challenges are proposed and discussed for the demonstration of their adaptability to different contexts and countries, thus leading to their massification.

Stigma toward mental disorders is one of today's most pressing global issues. The Covid-19 pandemic has exacerbated the barriers to social inclusion faced by individuals with mental disorders. Concurrently, stigma reduction interventions, especially those aimed at university students, have been more difficult to implement given social distancing and campus closures. As a result, alternative delivery for programs contributing to stigma reduction is required, such as online implementation. This paper reports the results of a controlled study focused on an online multi-component program on reducing stigma toward mental illness that included project-based learning, clinical simulations with standardized patients and E-Contact with real patients. A total of 40 undergraduate students from the Universidad del Desarrollo in Santiago, Chile, participated in the study. They were randomly divided between an intervention and control group. The intervention group participated in the online multi-component program, while the control group participated in an online educational program on cardiovascular health. We assessed the impact of the program by using the validated Spanish-language versions of the Attribution Questionnaire AQ-27 and the Questionnaire on Student Attitudes toward Schizophrenia with both groups, before and after the intervention. In addition, an ad hoc Likert scale ranging from 0 to 5 was used with the intervention group in order to assess the learning strategies implemented. Following the intervention, the participants belonging to the intervention group displayed significantly lower levels of stereotypes, perception of dangerousness, and global score toward people with schizophrenia (p < 0.001). In addition, participants presented lower levels of dangerousness-fear, avoidance, coercion, lack of solidarity, and global score (p < 0.001). The control group displayed no statistically significant differences in the level of stigma before and after the evaluation, for all of the items assessed. Finally, the overall assessment of each of the components of the program was highly positive. In conclusion, the study shows that online programs can contribute to reducing stigma toward mental disorders. The program assessed in this study had a positive impact on all the dimensions of stigma and all of the components of the program itself were positively evaluated by the participants.

Life satisfaction plays a crucial role in integral development and mental health during childhood and adolescence. Recently, it has been shown that cyberbullying has severe consequences for the mental health and wellbeing of victims such as increased anxiety, depressive symptoms and even suicide risk. Although the role of the family in life satisfaction and cyberbullying behaviors has been studied, there is limited information on its impacts during the current pandemic period. The aim of this study is to determine the role of family variables regarding students’ levels of life satisfaction and cyberbullying victimization during the pandemic period. Structural equation modeling was done using data from a cross-sectional study (n = 287; age ranged 14–18) conducted in six schools in Santiago, Chile during 2020. The tested model has a good fit and parsimonious adjustment. It explained 25.9% of the life satisfaction and 9% of the variance of cyberbullying victimization. Family support was positively associated with life satisfaction (p < 0.001) and negatively associated with cyberbullying victimization (p < 0.05). Likewise, family conflict was positively associated with levels of cyberbullying victimization (p < 0.05) and negatively associated with life satisfaction levels (p < 0.001). Finally, family visits were only positively associated with life satisfaction (p < 0.01). Generating interventions on several levels focused on positive family bonds has become essential and urgent. This is especially important considering their protective impacts on cyberbullying victimization in promotion of adolescent well-being and quality of life.

In Chile, during the COVID-19 pandemic, reports of cyberbullying victimization increased for adolescents and younger adults. Research has shown that cyber-victims—adolescents and young adults alike—are at greater risk for mental health problems such as depression as a result of this negative type of aggression. Yet, a paucity of research has examined the individual mechanisms germane to cyber-victim depression. We focused on loneliness for the current study. We hypothesized that cyber-victimization would be positively related to depressive symptoms through increased fears of loneliness and that this effect would differ between adolescents and younger adults. Thus, we examined a sample of 2370 participants from all main regions of Chile aged from 15 to 29 years. Moderated mediation results showed a negative effect of cyberbullying on depression, which was mediated by increased fears of being alone. The effect of frequency of cyberbullying on fear of loneliness was stronger for younger adults compared to adolescents. Our results suggest different mechanisms for both age groups, which can inform prevention programs and their specific activities.

Background: 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 Attribution questionnaire (AQ-27). 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. ClinicalTrials.gov Identifier: NCT05393596.

To analyze the association of perceived stress on the life satisfaction of Chilean adolescents during the recent pandemic, and to evaluate the moderating role that school community support provides. A total of 1337 adolescents in Chile (56.6% females), aged 14 through 19 (M = 15.99; SD = 1.3) participated. Descriptive statistics, a multiple linear regression model, and moderation analysis were all employed. Females were associated with lower levels of Life Satisfaction (B = −0.19, p = .042), which was not the case for the Age variable (p = .160). The level of Perceived Stress was shown to have a negative association on Life Satisfaction (B = −1.93, p < .001). The moderation analysis revealed an interaction factor between Perceived Stress and School Community Support as predictors of Life Satisfaction (B = 0.37, t = 4.91, p < .001), showing that higher levels of School Community Support moderated the negative effect of Perceived Stress on Life Satisfaction. Perceived stress during the pandemic had a negative association on life satisfaction. School community support was a protective factor for this negative effect, even in the case of online classes due to school closures. Strengthening the connection between adolescents and their school communities along with providing additional tools and resources in support of such a connection are both essential.
