Trust in government moderates the association between fear of COVID-19 as well as empathic concern and preventive behaviour.

With the COVID-19 pandemic, behavioural scientists aimed to illuminate reasons why people comply with (or not) large-scale cooperative activities. Here we investigated the motives that underlie support for COVID-19 preventive behaviours in a sample of 12,758 individuals from 34 countries. We hypothesized that the associations of empathic prosocial concern and fear of disease with support towards preventive COVID-19 behaviours would be moderated by trust in the government.

Acceptability, feasibility and fidelity of the culturally adapted version of Unplugged ("Yo Se Lo Que Quiero"), a substance use preventive program among adolescents in Chile: a pilot randomized controlled study.

Introduction: The consumption of alcohol, tobacco, and cannabis is a public health problem that impacts the cognitive, social, and emotional development of adolescents. Prevention strategies such as the "Unplugged" program are effective in delaying the progression of daily smoking and episodes of drunkenness among adolescents. "Yo Se Lo Que Quiero" (YSLQQ) corresponds to the adaptation of this program to the Chilean context.

Psychotic symptoms with and without a primary psychotic disorder in children requiring inpatient mental health admission.

Psychotic symptoms are relatively common in children and adolescents attending mental health services. On most occasions, their presence is not associated with a primary psychotic disorder, and their clinical significance remains understudied. No studies to date have evaluated the prevalence and clinical correlates of psychotic symptoms in children requiring inpatient mental health treatment.

Psychometric evidence of the Acceptance and Action Questionnaire-II (AAQ-II): an item response theory analysis in university students from Chile.

Background: Experiential avoidance (EA) is a psychological mechanism associated with several mental health disorders and is regarded as a relevant target by third-generation cognitive behavioral therapies. It has been mainly assessed through self-report questionnaires, and the AAQ-II is the most used tool. Its psychometric evidence has been mostly tested through the classical test theory (CTT) and very scarcely assessed through Item Response Theory (IRT).

The Coronavirus Anxiety Scale: Cross-national measurement invariance and convergent validity evidence.

Coronavirus Anxiety Scale (CAS) is a widely used measure that captures somatic symptoms of coronavirus-related anxiety. In a large-scale collaboration spanning 60 countries ( = 21,513), we examined the CAS's measurement invariance and assessed the convergent validity of CAS scores in relation to the fear of COVID-19 (FCV-19S) and the satisfaction with life (SWLS-3) scales. We utilized both conventional exact invariance tests and alignment procedures, with results revealing that the single-factor model fit the data well in almost all countries.

Visualizing Monocarboxylates and Other Relevant Metabolites in the Ex Vivo Drosophila Larval Brain Using Genetically Encoded Sensors.

The high energy requirements of brains due to electrical activity are one of their most distinguishing features. These requirements are met by the production of ATP from glucose and its metabolites, such as the monocarboxylates lactate and pyruvate. It is still unclear how this process is regulated or who the key players are, particularly in Drosophila.

Delays in the vaccination of infants between 2 and 18 months of age: associated factors in Chile.

Introduction: Infant vaccination has significantly reduced the morbidity and mortality of transmittable diseases worldwide. Its coverage is high (85%); however, partial or suboptimal vaccination has been an important public health problem. This study aimed (1) to design and explore the psychometric features of a questionnaire to determine the reasons for this partial or suboptimal vaccination; and 2) to determine the factors associated with delaying Diphtheria, Tetanus, Poliomyelitis (DTaP) vaccination.

Parental practices and their association with alcohol and cannabis use among adolescents in Chile.

Background: Adolescent alcohol and cannabis use are common in Chile. The present study aimed to assess the relationship between perceived parenting practices and alcohol and cannabis use among adolescents in a Latin American context.

Methods: We adapted and implemented a substance use prevention strategy in Chile, which included surveys of tenth-grade students from six municipalities in the Metropolitan Region of Greater Santiago.

Initial validation of the Multidimensional Adolescent Functioning Scale (MAFS) in Spanish-speaking students from Chilean secondary schools.

Introduction: Psychosocial functioning is closely associated with psychopathology and wellbeing in different populations, particularly adolescents. Despite its relevance, measures assessing psychosocial functioning in healthy adolescents are scant as most focus on adults or clinical populations. We evaluated the psychometric properties of the Multidimensional Adolescent Functioning Scale (MAFS), a self-report questionnaire created to assess three dimensions of psychosocial functioning ('general functioning', 'family-related functioning', and 'peer-related functioning') in adolescents from the general population.

Validation of the Spanish version of the Pediatric Symptom Checklist (PSC) to identify and assess psychosocial problems among early adolescents in Chile.

Background: The high prevalence of mental disorders in early adolescents, and their consequences, encourage the need for validated instruments to identify and assess psychosocial problems.

Objectives: i) To evaluate the psychometric properties of the Spanish version of the Pediatric Symptom Checklist (PSC) questionnaires (PSC-Y, 35 items, and PSC-17-Y) and its subscales (Attention, Internalizing and Externalizing subscales), including the assessment of the item structure, concurrent validity, and reliability; and ii) To assess possible associations between bullying experiences, school climate and school membership with psychological problems identified by the PSC questionnaire.

Methods: A cross-sectional study was carried out in 39 schools in Santiago, Chile.

Building bridges through cultural adaptation: Examining the initial impact of a culturally adapted parent training intervention for the Chilean context.

Child exposure to maltreatment and neglect constitutes a significant public health problem throughout Latin American and Caribbean (LAC) countries. Although evidence-based parent training (PT) interventions constitute an empirically demonstrated alternative to prevent child maltreatment and neglect, multiple implementation barriers have prevented the large-scale dissemination of evidence-based PT interventions across LAC countries. This selective prevention study consisted of an exploratory quasi-experimental design implemented in Chile, aimed at examining the initial impact of a culturally adapted version of the evidence-based PT intervention known as GenerationPMTO©.

Space Analysis of School Violence in the Educational Setting of Peru, 2019.

Background: Schools are increasingly experiencing physical, psychological, and sexual violence, which impacts students' academic achievement and physical and emotional health. Our objective was to identify regional prevalence rates, average prevalence by aggressor type, and provincial spatial conglomerates with higher rates for each type of school violence reported in educational settings in Peru during 2019.

Methods: An analysis was made of 12,132 cases reported through Peru's Specialized School Violence System (SíseVe).

The effectiveness of a tablet-based video game that stimulates cognitive, emotional, and social skills in developing academic skills among preschoolers: study protocol for a randomized controlled trial.

Background: Evidence suggests that children from low-income families begin the preschool stage with less academic and non-academic skills development compared to higher-income families. There are several successful experiences of early stimulation of cognitive and social-emotional skills; however, there is scarce evidence of the effectiveness of a video game that incorporates the stimulation of these skills simultaneously. This study aims to evaluate the effectiveness of a video game in stimulating cognitive, emotional, and social competence skills in developing academic skills in socioeconomically disadvantaged preschool children.

The Social Competence Promotion Program among Young Adolescents (SCPP-YA) in Chile ("Mi Mejor Plan") for substance use prevention among early adolescents: study protocol for a randomized controlled trial.

Background: Substance use is highly prevalent among children and adolescents in Chile, and it is known how it impacts their health and social adjustment. The call for effective prevention of substance use among children adolescents has resulted in numerous school-based programs, and particularly, the Social Competence Promotion Program among Young Adolescents (SCPP-YA) has been proved to be successful for promoting social and problem-solving skills in addition to preventing substance abuse in the US population. The purpose of this study is to test the effectiveness of the Social Competence Promotion Program among Young Adolescents (SCPP-YA) in Chile ("Mi Mejor Plan").

Effectiveness of the KiVa Antibullying Program with and without the Online Game in Chile: a Three-Arm Cluster Randomized Controlled Trial.

Bullying is a major health problem. The KiVa antibullying program has been evaluated in Finland and other European countries, showing preventive effects on self-reported bullying victimization and perpetration. No evaluations of this program have been conducted in Latin America.

Mental Health and Related Factors Among Undergraduate Students During SARS-CoV-2 Pandemic: A Cross-Sectional Study.

Background: Mental health problems among undergraduates are a significant public health concern. Most studies exploring mental health in this population during the pandemic have been conducted in high-income countries. Fewer studies come from Latin American countries.

The Unplugged program in Chile ("Yo Sé Lo Que Quiero") for substance use prevention among early adolescents: study protocol for a randomized controlled trial.

Background: Substance use is among the main contributors to disease among children and adolescents in the Americas region. The call for effective prevention of substance use among adolescents has resulted in numerous school-based programs, and particularly the Unplugged program has been proved to be successful in reducing the prevalence of different substances in seven European countries. The purpose of this study is to test the effectiveness of the Unplugged program in Chile ("Yo Sé Lo Que Quiero").

Use of Technology and Its Association With Academic Performance and Life Satisfaction Among Children and Adolescents.

In the last years, there has been a rise in the use of technology among children and adolescents, which has led to a greater concern about its impact on their socioemotional and cognitive development. To explore the time spent using technology, the risk perception of its use by students, and the association between frequency of technology use and life satisfaction and academic performance among children and adolescents in Chile. Additionally, we explored the mediating effect of sleep deprivation on these outcomes.

Experience of stigmatization in children receiving inpatient and outpatient mental health treatment: a longitudinal study.

Mental health-related stigma is poorly understood, and minimal research has focused on the experience of stigma from children's perspectives. We sought to investigate whether children treated as inpatients and outpatients had different experiences of stigma over time and whether stigma is linked to global functioning cross-sectionally and longitudinally. Children, aged 8-12 years, receiving treatment within a national specialist mental health inpatient unit were matched for age, gender and diagnosis with children receiving outpatient treatment (N = 64).

Polydrug Use and Co-occurring Substance Use Disorders in a Respondent Driven Sampling of Cocaine Base Paste Users in Santiago, Chile.

We characterized substance use patterns and co-occurring substance use disorders among active cocaine base paste (CBP) users in Santiago, Chile using data from respondent-driven sampling (RDS) in three areas of Metropolitan Santiago. Recruitment began with nine seeds, reaching 398 active CBP users (18% women; mean age 37.7 years), defined as persons consuming CBP at least twice per week in the last three months.

Validation of the European Drug Addiction Prevention Trial Questionnaire (EU-Dap) for substance use screening and to assess risk and protective factors among early adolescents in Chile.

Background: Substance use is highly prevalent among Chilean adolescents, and the damage it causes at the neurobiological, psychological, and social levels is known. However, there are no validated screening instruments that also assess risk and protective factors for this population in Chile, which is essential for evaluating future prevention interventions.

Objective: To determine the psychometric properties of the European Drug Addiction Prevention Trial Questionnaire (EU-Dap) questionnaire.
