RESUMO

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. METHODS: A cluster-randomized controlled trial design will be used. A tablet-based video game that stimulates cognitive and socio-emotional skills to improve the development of academic skills is compared with a tablet-based game where students draw and paint with no explicit stimulation of cognitive and socio-emotional skills. Eighteen schools and 750 Chilean preschool students will be recruited. The effectiveness of the intervention will be assessed using a direct evaluation of children on literacy learning and pre-calculation skills at baseline, immediately after stimulation, and at 6, 12, 18, and 24 months post-intervention. The mediating effect of working memory, inhibitory control, emotion recognition, and prosocial behaviours will be assessed on the effectiveness of the intervention. DISCUSSION: The proposed study will be the first to test the effectiveness of a tablet-based video game stimulating cognitive and social-emotional skills to improve academic skills in socioeconomically disadvantaged preschool children in Chile, controlling for gender, age (in months), mental health, and baseline conditions of stimulated skills. TRIAL REGISTRATION: ClinicalTrials.gov NCT05224700. Registered on February 2022.

RESUMO

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. A cluster randomized controlled trial was conducted at socially vulnerable schools in Santiago, Chile, to assess the effectiveness of the KiVa antibullying program in grades 5 and 6 (aged 10-12 years). Schools were randomly assigned (1:1:1) to three groups: the full KiVa group (including the online game), the partial KiVa group (did not include the online game), and the control group in which the regular school curriculum was implemented. The primary outcome was self-reported bullying victimization, assessed before the intervention (baseline) at the end of the academic year (November 2016) and post-intervention, 12 months after the baseline assessment (November 2017). This trial is registered with ClinicalTrials.gov, number NCT02898324. A total of 39 schools (13 in each group) were included; no schools withdrew. The baseline survey included 5923 participants, and the endpoint survey included 3968 participants. Participants in the partial KiVa group had lower bullying victimization at the endpoint survey than those in the control group (OBVQ-R adjusted mean difference - 0.14; 95% CI, - 0.26 to - 0.01; effect size - 0.13, 95% CI - 0.24 to - 0.01, p = 0.035). There was no effect of the full KiVa group for bullying victimization compared with the control and partial KiVa groups. Compared to the control group, participants in the partial KiVa group had lower witnessing bullying at school (adjusted mean difference = - 0.25; 95% CI - 0.45 to - 0.05; effect size - 0.18, 95% CI, - 0.32 to - 0.04, p = 0.013). No effects were found for other secondary outcomes, including bullying perpetration in any comparisons between arms. The implementation of the KiVa antibullying program had mixed results in Chile. There was only a small effect on bullying victimization and witnessing when KiVa was delivered without the online game.

RESUMO

Bullying is a phenomenon that affects children and adolescents worldwide, and it has major consequences for all participants involved in these situations. In Chile, researchers have validated several instruments used to investigate aggression between peers and school violence, but there is a lack of validation of instruments to investigate bullying. The purpose of this study was to provide evidence of the validity and reliability of the Olweus Bully/Victim Questionnaire-Revised version (OBVQ-R) in the Chilean context. The participants were 2,775 students from schools of low, medium, and high socioeconomic status. OBVQ-R is a self-report questionnaire with 42 items, which has been used in different countries, and has adequate psychometric properties to assess the prevalence of victimization and aggression and various forms of bullying worldwide. Results confirmed the two-factor structure of the OBVQ-R (victimization and perpetration subscales) and good reliability (ω = 0.81 and ω = 0.75, respectively). These dimensions seem to be correlated. Comparison between OBVQ-R with the School Violence between Peers Questionnaire and the Internet Experiences Questionnaire showed some degree of agreement. The Item Response Theory analysis showed that the item about verbal bullying, in both subscales, had the lowest-severity parameters, meaning that these forms of bullying were the most prevalent. The higher-severity parameter in the victimization scale was the cyberbullying item, and the sexual bullying item showed higher severity in the perpetration subscale. The differential item functioning analysis by gender showed a trend in which boys responded with lower-severity parameters than girls. In the victimization scale, the exception was the item about spreading rumors, and in the perpetration subscale, it was the item about racial bullying. We have provided evidence of the validation of OBVQ-R among school-age children and adolescents in Chile. This study is part of a trial registered at ClinicalTrials.gov, number NCT02898324.

RESUMO

Resumen Existe un robusto cuerpo de literatura que sustenta la importancia de desarrollar las habilidades de autorregulación (memoria de trabajo, atención y control inhibitorio) desde los primeros años, dada la vinculación que tiene tanto con los logros del presente como con el éxito futuro (p.e. adaptación al contexto escolar, logros académicos, participación social). Esta revisión tiene por objetivo sintetizar la información de la investigación neurocientífica en el tema de la autorregulación, entre los años 2000 y 2019, la cual ha aportado información para comprender mejor: (1) los procesos de desarrollo entre los 0 y 8 años, de cada una de estas habilidades mencionadas y (2) algunos de los factores que intervienen en este proceso. Los resultados confirman que tanto la madurez cronológica como las experiencias que tienen los niños, favorecerán el óptimo desarrollo de estas habilidades. Así también, se confirma que cada habilidad tiene su propio proceso y tiempo para emerger y consolidarse, lo que tiene una manifestación conductual y neurológica. En relación con los factores, existen algunos de orden biológico y otros contextuales o sociales que van a influir en cómo estas habilidades se desarrollan y se expresan en la vida cotidiana.


Abstract A robust body of literature confirms the importance of developing the skills of self-regulation (working memory, attention and inhibitory control) from the early years, considering their impact on the achievements of the present and future success (eg adaptation to the school context, academic achievements, social participation). The aim of this review is to summarize the information on neuroscientific research on the topic of self-regulation, between 2000 and 2019, which has provided information to better understanding: (1) development processes between 0 and 8 years of age, each of these skills mentioned and (2) some of the factors involved in this process. The results confirm that both the chronological maturity and the experiences of the children will favor the optimal development of these skills. Additionally, each skill emerges and takes roots according to its own processes and time frames, turning into behavioral and neurological manifestations. Relevant factors can be either biological or contextual/social that will influence how these skills are developed and expressed in everyday life.

RESUMO

The Strengths and Difficulties Questionnaire (SDQ) is a screening tool used to measure psychological functioning among children and adolescents. It has been extensively used worldwide, but its psychometric properties, such as internal structure and reliability, seem to vary across countries. This is the first study exploring the construct validity and reliability of the Spanish version of SDQ among early adolescents (self-reported) and their parents in Latin America. A total of 1,284 early adolescents (9-15 years) and their parents answered the SDQ. We also collected demographic variables. A confirmatory factor analysis was conducted to assess the latent structure of the SDQ. We also used the multitrait-multimethod analysis to separate the true variance on the constructs from variance resulting from measurement methods (self-report vs. parent report), and evaluated the agreement between adolescents and their parents. We found that the original five-factor model was a good solution and the resulting sub-scales had good internal consistency. We also found that the self-reported and parental versions of SDQ provide different information, which are complementary and provide a better picture of the emotional, social, and conduct problems of adolescents. We have added evidence for the construct validity and reliability of the Spanish self-reported and parental SDQ versions in a Chilean sample.

RESUMO

Resumen Los objetivos de este estudio fueron, comparar las funciones ejecutivas (atención, flexibilidad, control inhibitorio, planificación y memoria de trabajo) de niños preescolares con y sin trastorno del lenguaje y definir un perfil de funciones ejecutivas. El diseño es no experimental con propósitos descriptivos/comparativos. La muestra estuvo conformada por 105 niños. El grupo con trastorno del lenguaje estaba compuesto por 31 niños y 19 niñas, edad promedio 4.68 años, de Escuelas Especiales de Lenguaje. El grupo sin trastorno del lenguaje estaba compuesto por 15 niños y 24 niñas, edad promedio 4.98 años, de Escuelas Públicas de la ciudad de Concepción en Chile. Los resultados muestran que hay evidencia estadísticamente significativa para declarar que los puntajes obtenidos por niños/as con trastorno del lenguaje son inferiores a sus pares sin trastorno del lenguaje en todas las funciones ejecutivas evaluadas, lo que respalda la literatura vigente sobre el tema. En cuanto al perfil de funciones ejecutivas, la función que podría predecir la presencia de trastorno del lenguaje en un preescolar es la función ejecutiva de planificación. Resulta de interés seguir profundizando el perfil de funciones ejecutivas en niños con trastorno del lenguaje y su relación específica con los problemas lingüísticos que estos niños/as presentan.


Abstract The objectives of this study were to compare the executive functions (attention, flexibility, inhibitory control, planning and working memory) of preschool children with and without language disorder and to define a profile of executive functions. The design is non-experimental for descriptive/comparative purposes. The sample consisted of 105 children. The group with language disorder was composed of 31 children and 19 girls, average age 4.68 years, of Special Language Schools. The group without language disorder was composed of 15 children and 24 girls, average age 4.98 years, of Public Schools of the city of Concepcion in Chile. The results show that there is statistically significant evidence to state that the scores obtained by children with language disorders are lower than their peers without language disorder in all the executive functions evaluated, which supports the current literature on the subject. Regarding the profile of executive functions, the function that could predict the presence of language disorder in a preschool is the executive planning function. It is interesting to continue deepening the profile of executive functions in children with language disorder and their specific relationship with the linguistic problems that these children have.

RESUMO

BACKGROUND: Bullying is a major problem worldwide and Chile is no exception. Bullying is defined as a systematic aggressive behavior against a victim who cannot defend him or herself. Victims suffer social isolation and psychological maladjustment, while bullies have a higher risk for conduct problems and substance use disorders. These problems appear to last over time. The KiVa antibullying program has been evaluated in Finland and other European countries, showing preventive effects on victimization and self-reported bullying. The aims of this study are (1) to develop a culturally appropriate version of the KiVa material and (2) to test the effectiveness of the KiVa program, with and without the online game, on reducing experiences of victimization and bullying behavior among vulnerable primary schools in Santiago (Chile), using a cluster randomized controlled trial (RCT) design with three arms: (1) full KiVa program group, (2) partial KiVa (without online game) program group and (3) control group. METHODS AND DESIGN: This is a three-arm, single-blind, cluster randomized controlled trial (RCT) with a target enrolment of 1495 4th and 5th graders attending 13 vulnerable schools per arm. Students in the full and partial KiVa groups will receive universal actions: ten 2-h lessons delivered by trained teachers during 1 year; they will be exposed to posters encouraging them to support victims and behave constructively when witnessing bullying; and a person designated by the school authorities will be present in all school breaks and lunchtimes using a visible KiVa vest to remind everybody that they are in a KiVa school. KiVa schools also will have indicated actions, which consist of a set of discussion groups with the victims and with the bullies, with proper follow-up. Only full KiVa schools will also receive an online game which has the aim to raise awareness of the role of the group in bullying, increase empathy and promote strategies to support victimized peers. Self-reported victimization, bullying others and peer-reported bullying actions, psychological and academic functioning, and sense of school membership will be measured at baseline and 12 months after randomization. DISCUSSION: This is the first cluster RCT of the KiVa antibullying program in Latin America. TRIAL REGISTRATION: ClinicalTrials.gov, Identifier: NCT02898324 . Registered on 8 September 2016.

RESUMO

BACKGROUND: The promotion of healthy behaviors is a relevant issue worldwide, especially among adolescent populations, as this is the developmental stage where most unhealthy behaviors become ingrained. PURPOSE: The aim of this study was to analyze the psychometric properties of the Spanish version of the Adolescent Health Promotion Scale (AHPS) in a Chilean sample of early adolescents. METHODS: The sample was composed of 1,156 adolescents aged 10-14 years from schools in San Felipe, Chile. Item structure was assessed using exploratory and confirmatory factor analyses; reliability was measured using Cronbach's alpha; and differences in terms of gender, age, and socioeconomic status (SES) were established using analysis of variance. RESULTS: The analyses of item structure identified all of the six original factors (nutrition behaviors, health responsibility, social support, life appreciation, stress management and exercise behavior) as significant. However, eight items did not fit the Chilean population well. Therefore, the AHPS in Chile has been reduced to 32 items. The Cronbach's alpha of the 32-item Chilean AHPS was .95, with the subscale coefficients ranging from .76 to .94. In addition, female subjects performed better than male subjects, and individuals of higher SES scored higher than the middle and lower socioeconomic groups. No differences on AHPS scores were found in different age groups. CONCLUSIONS: The AHPS appears to have good psychometric properties in terms of item structure and reliability. Consistent with studies carried out in other countries, health promotion behavioral differences were observed in association with gender and SES. The results support the Chilean version of the AHPS as an appropriate instrument for measuring the health promotion behaviors of early adolescents in Chile and for comparing results with those from other countries.

RESUMO

School membership appears to be an important factor in explaining the relationship between students and schools, including school staff. School membership is associated with several school-related outcomes, such as academic performance and expectations. Most studies on school membership have been conducted in developed countries. The Psychological Sense of School Membership (PSSM) scale (18 items: 13 positively worded items, 5 negatively worded items) has been widely used to measure this construct, but no studies regarding its validity and reliability have been conducted in Spanish-speaking Latin American countries. This study investigates the psychometric properties, factor structure and reliability of this scale in a sample of 1250 early adolescents in Chile. Both exploratory and confirmatory factor analyses provide evidence of an excellent fit for a one-factor solution after removing the negatively worded items. The internal consistency of this new abbreviated version was 0.92. The association analyses demonstrated that high school membership was associated with better academic performance, stronger school bonding, a reduced likelihood of school misbehavior, and reduced likelihood of substance use. Analyses showed support for the reliability and validity of the PSSM among Chilean adolescents.

RESUMO

BACKGROUND: Family behavior models may influence health promoting conducts among adolescents. AIM: To determine the association between health promoting behaviors among parents and healthy behaviors of early adolescents. MATERIAL AND METHODS: Analysis of the baseline assessment of a longitudinal study of early adolescents in the city of San Felipe, Region of Valparaiso, Chile. Parents and their teenage children, attending 5th to 7th grade, from ten municipal schools, participated in this study. Self-reported questionnaires were used to assess healthy lifestyles, answered separately by parents and their children. Univariable and multivariable ordinal logistic regression analyses with complete data were carried out, using the students’ health promoting behaviors as dependent variables and the same behaviors among parents as the main predictors, controlling for other personal and family variables. RESULTS: We contacted 1,035 parents and 682 consented to participate along with 560 students. The mean age of adolescents was 11.5 ± 1.2 years (49% females) The mean age of parents was 39.8 ± 8.8 years and 90% were women. The parental behaviors associated with teenage health promoting behaviors were eating vegetables (odds ratio (OR) = 1.22, p < 0.05), having breakfast (OR = 1.27, p < 0.05), do stretching exercises every day (OR = 1.19, p < 0.05) and take some time for relaxation (OR = 1.24, p < 0.05). CONCLUSIONS: These results show an association between healthy behaviors among parents and these behaviors among their adolescent offspring.

RESUMO

BACKGROUND: Smoking and alcohol use are risky behaviors that can start early in life. AIM: To determine the lifetime prevalence of tobacco and alcohol use in adolescents aged 10 to 14 years and related factors. SUBJECTS AND METHODS: A survey about smoking and alcohol use was answered by 1,392 teenagers aged 10 to 14 years (46% women) from seven schools in a small city near Santiago. Personal, family, and school factors were evaluated through self-report scales. Smoking and alcohol use, as dichotomous dependent variables, were defined as having consumed any of these substances throughout life. Prevalence was calculated as percentages with 95% confidence intervals. Association analyses were conducted using multivariable logistic regression models. RESULTS: Six and eleven percent of participants reported having smoked and used alcohol in their life, respectively. Smoking was associated with age, having behavioral problems, mothers’ smoking, perceiving that parents had drug problems, and not living with both parents. Alcohol use was mainly associated with age, having behavioral problems, perceiving that other students consumed drugs, alcohol use by both parents, and perceiving a lack of family support. CONCLUSIONS: Tobacco and alcohol use is highly prevalent in adolescents aged 10-14 years. There were common risk factors for smoking and alcohol use such as age and having behavioral problems, while other factors were more specific such as mothers’ smoking, or parental alcohol use.

RESUMO

BACKGROUND: Health-promoting behaviors are important to prevent diseases and prolong life in the population. People develop these behaviors throughout life. However, better benefits for health are obtained with an early development. AIM: To determine the prevalence of health-promoting behaviors among early adolescents and its associated factors. MATERIAL AND METHODS: Cross-sectional survey performed in 1,465 students of high, medium and low socio-economic status, attending fifth to eighth grades of schools located in a small Chilean city. Participants answered a questionnaire that gathered information about frequency of health-promoting behaviors such as health responsibility and nutrition, physical exercise and stress management, life appreciation, social support and different personal, school and familial factors. RESULTS: A higher frequency of health-promoting behaviors was associated with better academic achievement, better school commitment, and higher perception of school membership. It also was associated with a better perception of health status and a higher conformity with physical appearance. CONCLUSIONS: Health promoting behaviors in these children are related to a better academic achievement and a higher integration with school environment.

RESUMO

BACKGROUND: Memory is affected differently with the passage of time; specifically, episodic memory presents a clear decline. There is a relationship of this memory impairment and degenerative and psychiatric diseases. AIM: To determine the reliability and validity of the University of Southern California Repeatable Episodic Memory Test (USC-REMT) in a sample of Chilean adults. MATERIAL AND METHODS: The instrument was administered to 178 subjects living in the Metropolitan Region of Santiago. The sessions were individual, during the morning, lasting approximately 15 minutes. RESULTS: The ANOVA indicates that subjects over 61 years old had lower scores in the test than their younger counterparts. There was an inverse correlation between age and success in "Free recall" (r =- 0.570), "Recognition indicating yes-no" (r = -0.412) and "forced-choice recognition" (r =- 0.371). Regression analysis showed that age explained 32.1 % "free recall" variance. The three components were grouped into a single factor. CONCLUSIONS: The USC-REMT meets the criteria for validity and reliability to be applied for clinical and research purposes.

RESUMO

BACKGROUND: Self-esteem is positively associated to the well being of people and could be a good mental health indicator. AIM: To determine the reliability and validity of the Rosenberg Self-esteem Scale in a Chilean adult sample. MATERIAL AND METHODS: The instrument was applied to 473 subjects living in the Metropolitan Region of Santiago, evenly distributed according to gender, age, educational level and income. The Neugarten Life Satisfaction index (LSI-A) was also applied to the sample. RESULTS: Cronbach's alpha for reliability of the scale was 0.754. There was no gender bias and factor analysis grouped items into two factors (5 positive and 5 negative). The instrument had a correlation of 0.455 with the LSI-A. CONCLUSIONS: The Rosenberg Self-esteem Scale meets the criteria for validity and reliability of a quality instrument to measure self-esteem in Chile.

RESUMO

Se presentan los resultados obtenidos en la estimación de la confiabilidad y la validez del índice de Satisfacción Vital (LSI-A) de Neugarten, Havighurst & Tobin (1961,1996). La muestra estuvo constituida por 473 adultos de 30 a 75 años (hombres y mujeres) de la Región Metropolitana de Santiago de Chile, distribuidos en tres niveles de ingreso, tres grupos de edad y tres niveles de escolaridad. Se estimó la validez de contenido, concurrente y de constructo del instrumento, definiendo 5 factores que explican el 50.62 por ciento de la varianza. La confiabilidad con alpha de Cronbach fue de 0.80 para la muestra completa, el índice varió entre 0.77 a 0.83 según edad, entre 0.77 y 0.81 según nivel educacional y entre 0.74 y 0.83 según nivel de ingreso; no se observaron variaciones según sexo (0.80).


The findings of a research aimed to estimate reliability and validity of The Life Satisfaction index (LSI-A) of Neugarten, Havighurst & Tobin (1961; 1996) are presented. The sample consisted of 473 adults from 30 to 75 years (male and female) from Metropolitan Region of Santiago, Chile, distributed into three levels of income, age groups and educational levels. The content, concurrent and construct validity of the instrument was estimated, defining five factors accounting for 50.62 percent of the variance. The reliability with Cronbach's alpha was 0.80 for the full sample, the index ranged between 0.77 to 0.83 depending on age, between 0.77 and 0.81 according to educational level and between 0.74 and 0.83 depending on income level, no changes were observed by sex (0.80).
