Ítem Calidad de sueño y rendimiento académico en alumnos de educación secundaria(Sociedad Médica de Santiago, 2017) Bugueño, M.; Curihual, C.; Olivares, P.; Wallace, J.; López-Alegría, F.; Rivera-López, G.; Oyanedel, J.C.Background: Sleeping and studying are the day-to-day activities of a teenager attending school. Aim: To determine the quality of sleep and its relationship to the academic performance among students attending morning and afternoon shifts in a public high school. Material and Methods: Students of the first and second year of high school answered an interview about socio-demographic background, academic performance, student activities and subjective sleep quality; they were evaluated using the Pittsburgh Sleep Quality Index (PSQI). Results: The interview was answered by 322 first year students aged 15 ± 5 years attending the morning shift and 364 second year students, aged 16 ± 0.5 years, attending the afternoon shift. The components: sleep latency, habitual sleep efficiency, sleep disturbance, drug use and daytime dysfunction were similar and classified as good in both school shifts. The components subjective sleep quality and duration of sleep had higher scores among students of the morning shift. The mean grades during the first semester of the students attending morning and afternoon shifts were 5.9 and 5.8, respectively (of a scale from 1 to 7). Among students of both shifts, the PSQI scale was associated inversely and significantly with academic performance. Conclusions: A bad sleep quality influences academic performance in these students.Ítem Cumplimiento del flujo de decisiones clínicas de los algoritmos de derivación y confirmación diagnóstica del primer PAP atípico H1-Santiago Sur(Sociedad Chilena de Obstetricia y Ginecologia, 2018-09) López-Alegría, F.; Quezada, O.P.; Oyanedel, J.C.Antecedentes: Un algoritmo puede definirse como un conjunto de operaciones y procedimientos que se deben seguir con el fin de resolver un problema. Objetivo: Conocer el cumplimiento del flujo de decisiones clínicas del protocolo preconizado en los algoritmos de derivación y de confirmación diagnóstica para la citología cervical atípica de significado indeterminado – H1, estipulados en el Programa Nacional de Búsqueda y Control del Cáncer Cervical de Chile. Métodos: Estudio epidemiológico de tipo descriptivo, observacional, cuantitativo y de seguimiento de una cohorte de mujeres portadoras de un primer informe de citología cervical atípica de significado indeterminado – H1, pertenecientes a los consultorios de Atención Primaria de Salud del área Metropolitana Sur de Santiago, Chile. El seguimiento fue a través de la aplicación de los “Algoritmo de derivación a especialista o U.P.C. del primer PAP atípico según la clasificación Bethesda 2001” y “Algoritmos para confirmación diagnóstica”. Resultados: Se seleccionaron 446 mujeres con un primer informe H1. El cumplimiento de conductas de acuerdo al algoritmo de derivación fue de 42.4% y las conductas alternativas fue de 5.8%. La adherencia de conducta en los algoritmos para confirmación diagnóstica fue cumplida en un 89.6%. Conclusiones: El cumplimiento de las conductas ajustadas a algoritmo de derivación del primer Pap atípico fue realizado por la mitad de las mujeres y el cumplimiento del algoritmo de confirmación diagnóstica fue realizado por la gran mayoría.Ítem Gratitude at work prospectively predicts lower workplace materialism: A three-wave longitudinal study in Chile(MDPI AG, 2021-04) Unanue, J.; Oriol, X.; Oyanedel, J.C.; Rubio, A.; Unanue, W.Materialism at work refers to a higher importance attached to extrinsic (e.g., money, fame, image) versus intrinsic (self-development, affiliation, community participation) employees’ ‘aspirations’. Research from self-determination theory has consistently found that materialism at work is strongly detrimental for both employees and organizations. For example, materialism is negatively associated with lower job satisfaction and engagement and positively associated with higher turnover intentions and job insecurity. Unfortunately, there are no viable strategies for reducing materialism in the workplace yet. In this sense, based on emergent research in psychology, we theorized that dispositional gratitude—a key construct within the Positive Organizational Psychology field—could be a protecting factor against materialism. Further, we conducted a three-wave longitudinal design among a large sample of Chilean workers (n = 1841) to test, for the first time, the longitudinal link between gratitude and materialism. We used two novel methodologies: A cross-lagged panel model (CLPM) to test between-person changes and a trait-state-occasion model (TSO) to test within-person changes. We found that both the CLPM as well as the TSO models showed that gratitude at work prospectively predicted further lower workplace materialism. Specifically, the CLPM shows that individuals with higher than average gratitude at Ti, are more likely to show lower than average materialism at Ti+1. The TSO shows that individuals with a higher than their usual level of gratitude at Ti are more likely to show a lower than their usual level of materialism at Ti+1. Important implications for materialism research as well as for the Positive Organizational Psychology field are discussed. © 2021 by the authors.

What schools can do to improve school achievement and reduce school failure is a critical issue, both for school management and teacher training. In this study, we present the association of individual and school-related socio-emotional variables with school achievement and performance, controlling for the effects of SES. A probabilistic sample of 4,964 students, drawn from 191 schools enrolled in year 10 in urban areas of Chile, answered questionnaires assessing subjective wellbeing, social wellbeing in school, school climate, school social wellbeing and students' perceptions of teachers' wellbeing. Using structural equation modeling, and controlling for SES, we modeled subjective wellbeing as a mediator of the relationship between school-related variables, such as school climate and perception of teacher's wellbeing, and (a) school achievement, and (b) school performance. School achievement was computed as a product of (a) the probability of passing the school year, and (b) the percentage of yearly attendance at school. Data on school achievement was drawn from administrative registries from the Chilean Ministry of Education. School performance was computed as the estimated grade point average (GPA) at the end of the school year, based on the students' previous 5-year GPAs, and was also obtained through administrative data of the last 5 years. Findings reveal the mediating role of subjective wellbeing in the relationship between school-related evaluations (students' social wellbeing at school, their perception of teachers' wellbeing and school climate) and school achievement. For school achievement, two variables were mediated (students' social wellbeing at school and school climate). However, for school performance, no significant mediations were found. We conclude that, on the one hand, after controlling for SES, students' individual subjective wellbeing is associated with their achievement and performance in school. We discuss the importance of improving school experiences that may protect and promote students' subjective experience and school achievement and performance, and reduce the probability of school failure and dropout.Ítem Social Support and Substance Use as Moderators of the Relationship Between Depressive Symptoms and Suicidal Ideation in Adolescents(Frontiers Media S.A., 2020-09) Rubio, A.; Oyanedel, J.C.; Cancino, F.; Benavente, L.; Cespedes, C.; Zisis, C.; Paez, D.Literature reports that depressive symptoms may precede suicidal ideation. Several studies have identified social support and substance use as moderators of this relationship. However, no study has evaluated these variables together by testing how substance use can affect the moderating effect of social support in this relationship. The purpose of this article is to individually evaluate dimensions of social support (friends, family, significant others, and school) and substance use (alcohol, marijuana, and other illicit drugs), as moderators of the relationship between depressive symptoms and suicidal ideation, as well as analyze the moderating role of substance use in the moderation exerted by social support in this relationship. This study, quantitative and cross-sectional, considered 775 adolescents [Average age = 15.48 (SD = 0.96), 45.9% women], from 20 randomly selected schools in Santiago de Chile. Simple moderation models were used to analyze possible moderators separately, and double moderation models were used to analyze the moderating role of substance use in the moderating effect of social support. The results show that the four dimensions of social support moderate the relationship between depressive symptomatology and suicidal ideation, showing the strongest interaction in the case of family support, followed by support of a significant person, support at school, and support of friends, in that order. On the other hand, alcohol was the only drug that moderated the relationship in question. In addition, the results show that the use of alcohol limits the moderating effect of social support in the fields of family, significant person, and school support, but not in the case of support of friends. The use of marijuana and other illicit drugs did not affect the moderating effects of social support for any of the areas evaluated. The results are discussed according to the different roles that alcohol use can play in adolescence, and how these, together with perceived social support, are related to the emergence of suicidal ideation from depressive symptoms. © Copyright © 2020 Rubio, Oyanedel, Cancino, Benavente, Céspedes, Zisis and Páez.Ítem Suicidal Ideation Mediates the Relationship Between Affect and Suicide Attempt in Adolescents.(Frontiers Media S.A., 2020-12) Rubio, A.; Oyanedel, J.C.; Bilbao, M.; Mendiburo-Seguel, A.; López, V.; Páez, D.Suicide, as one of the leading causes of death for the adolescent population, both in Chile and globally, remains a complex and elusive phenomenon. This research studies the association between positive and negative affect in relation with suicidal ideation and suicidal attempt, given that affectivity is a fundamental basis on which people make evaluations on their satisfaction with life. First, it examines the reliability, structure, and validity of Watson’s positive and negative affect scale (PANAS) scale in a representative random sample of Chilean high school students (N = 4,568). The scale evidences strong reliability coefficients and a confirmatory factor analysis, excluding one positive (excited) and one negative (nervous) item. The scale shows a satisfactory goodness of fit. Secondly, it investigates the association of PANAS positive and negative affect scores with suicidal ideation as well as reported attempt in adolescents, controlling for the potential effect of age and sex (N = 420 high school students). Low positive and high negative affect, but not sex and age, show a significant association with suicidal ideation. Suicidal ideation totally mediates the association of affect with suicide attempt, as expected. Results are discussed regarding prevention and it considers how positive and negative affect can be relevant as indicators for prevention and treatment using widely available technology.Ítem The Role of Self-control and Grit in Domains of School Success in Students of Primary and Secondary School(Frontiers Media, 2017-10) Oriol, X.; Miranda, R.; Oyanedel, J.C.; Torres, J.Objective: Self-control and grit have become two of the most important variables that explain success in different aspects of people's daily life (Duckworth and Gross, 2014). Self-control promotes delayed gratification and directly influences thoughts, emotions, and impulses. On the other hand, grit enhances the achievement of goals through perseverance even before extreme external circumstances. Since both constructs are related, examining them together is compelling, as long as the different nuances that characterize each are taken into account. Two structural equation models (SEM) were conducted to observe the effect of self-control and grit on a more specific indicator of academic success (academic self-efficacy) and a more general indicator of school experience (satisfaction with school). Methods: The first model comprises 5,681 primary students (M = 9.05; SD = 0.79), and the second 10,017 secondary students (M = 14.20; SD = 1.04) from Lima, Peru. In both models, the influence of grit and self-control on school satisfaction was observed when taking self-efficacy as a mediator variable. Results: The results show that grit and self-control have strong associations in both primary and secondary students. When estimating the covariance of both constructs, grit is related with academic-self efficacy at both educational stages, but only to satisfaction with school in secondary students. On the contrary, self-control shows a significant relationship with school satisfaction only in primary education. In turn, self-efficacy shows a mediating effect between grit and school satisfaction. After calculating the invariance of the models, differences are observed by gender in the relationships between variables. Conclusion: The results indicate that both constructs are strongly interrelated. Regarding the associations with the indicators of academic success, a need for timely interventions specific to each educational stage is observed.
