RESUMO

BACKGROUND: The objective of this study was to evaluate the spatial and temporal patterns of disease prevalence clusters of dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) virus and how socio-economic and climatic variables simultaneously influence the risk and rate of occurrence of infection in Mexico. METHODS: To determine the spatiotemporal clustering and the effect of climatic and socio-economic covariates on the rate of occurrence of disease and risk in Mexico, we applied correlation methods, seasonal and trend decomposition using locally estimated scatterplot smoothing, hotspot analysis and conditional autoregressive Bayesian models. RESULTS: We found cases of the disease are decreasing and a significant association between DENV, CHIKV and ZIKV cases and climatic and socio-economic variables. An increment of cases was identified in the northeastern, central west and southeastern regions of Mexico. Climatic and socio-economic covariates were significantly associated with the rate of occurrence and risk of the three arboviral disease cases. CONCLUSION: The association of climatic and socio-economic factors is predominant in the northeastern, central west and southeastern regions of Mexico. DENV, CHIKV and ZIKV cases showed an increased risk in several states in these regions and need urgent attention to allocate public health resources to the most vulnerable regions in Mexico.

RESUMO

Abstract Law can shape individual and social behavior in different ways including through perceived control and legitimacy of authorities. The primary aim of this study was to investigate whether legitimacy of authorities, social and personal control, and social cohesion influence antisocial behaviors in juvenile offenders. The study, included a sample of two hundred juvenile offenders in Mexico, used structural equation modeling to test the relationship between the perception of just treatment by police and judges (i.e., legitimacy) and social and personal control and outcomes of antisocial behaviors and tendencies (self-report and probability of antisocial behavior as well as reports of peer antisocial behavior). Results indicate legitimacy of authorities and personal control had a negative effect while social control showed a positive effect on these behaviors. Social cohesion had a positive effect on social control. Our results suggest that legitimacy of authorities and personal control act as protective factors against antisocial behaviors whereas, contrary to the expected results, social control may be a risk factor. This research highlights the importance of preventative protective efforts in juvenile offenders such as just treatment and development of personal control rather than the use of punitive processes. In this sense, it is important to consider alternatives for judicial involvement and punishment such as community programs as well as cognitive and emotional prevention and intervention efforts to reduce antisocial behaviors. Programs such as the Reasoning and Rehabilitation Program, other cognitive skill interventions as well as developmental prevention programs have shown efficacy.

Resumen La ley puede modelar la conducta de diferentes maneras, consecuentemente, el objetivo de este estudio fue analizar los efectos de la legitimidad, el control social y personal, y la cohesión social en la conducta antisocial de jóvenes infractores. Doscientos menores infractores en México contestaron un cuestionario realizado para este estudio. Los datos fueron analizados a través de ecuaciones estructurales. Cuatro factores fueron especificados: Legitimidad de las autoridades, relacionada con la percepción de tratamiento justo por parte de policías y jueces. Disuasión y norma social conformaron la variable de control social. Orientación al futuro, normas personales y autodeterminación integraron la variable de control personal. La variable conducta antisocial resultó del autoreporte respecto a la conducta antisocial y la probabilidad de conducta antisocial, y del reporte de la conducta antisocial de los amigos. Los resultados indicaron un efecto negativo de la legitimidad y el control personal y uno positivo del control social en la conducta antisocial. La cohesión social tuvo un efecto positivo en el control social. Contrario a lo esperado el control social tuvo un efecto positivo en la conducta antisocial. Por lo tanto, se deben considerar alternativas al "tratamiento" en internamiento (cárcel), ya que la disuasión y el castigo no producen los efectos esperados de retraer a los adolescentes de que cometan delitos. La alternativa pudiera ser los programas de tratamiento comunitarios, así como programas de prevención e intervención que contemplen aspectos emocionales y cognitivos.

RESUMO

Antisocial behavior (AB) is a complex phenomenon, predicted by a wide range of biological, environmental, and personality factors. These have high human and economic costs especially in adolescents, highlighting the importance of investigating factors that may be associated with these behaviors. Among the most potent predictors of AB are early life experiences and personality. To this end, the present study sought to investigate the association between early life parental abuse and behavioral activation system (BAS) personality traits assessed within the reinforcement sensitivity theory (RST) framework and antisocial behaviors in Mexican adolescents. Our sample consisted of 342 adolescents (Mage = 17, SD = 2.47) from northwestern Mexico. Participants, after parental consent and participant consent/assent (if minors), self-reported early life parental abuse, current BAS personality traits, and antisocial behaviors. Through structural equation models, our results suggest there is a positive association between early life parental abuse and antisocial behaviors, as well as a negative association with BAS personality traits (R2 = 37%). These results contribute to the current literature by suggesting that personality and environmental variables can predict adolescent antisocial behaviors. Future studies should explore the interplay between these variables longitudinally and investigate both risk and protective factors, as well as negative and positive outcomes.

RESUMO

The first lines of defense during an epidemic are behavioral interventions, including stay-at-home measures or precautionary health training, aimed at reducing contact and disease transmission. Examining the psychosocial variables that may lead to greater adoption of such precautionary behaviors is critical. The present study examines predictors of precautionary practices against coronavirus disease 2019 (COVID-19) in 709 Mexican participants from 24 states. The study was conducted via online questionnaire between the end of March and the beginning of April 2020, when the pandemic response was in its initial stages in Mexico. The instrument included demographic items, as well as scales assessing COVID-19-resembling symptoms, empathy, impulsivity, anhedonic depression, general health practices, alcohol consumption, and COVID-19-associated precautionary behaviors. Most participants reported adopting limited social distancing or other precautionary behaviors against COVID-19. The results of a structural equation model demonstrated that the presence of COVID-19 symptoms was related to impulsivity and general health behaviors. However, no direct association between precautionary behaviors and the presence of COVID-19 symptoms was found. In turn, precautionary behaviors were more prevalent among participants who reported higher empathy and general health behaviors and were inhibited indirectly by impulsivity via alcohol consumption. Furthermore, the model suggests that anhedonic depression symptoms have a negative indirect effect on precautionary behaviors via general health behaviors. Finally, impulsivity showed a negative direct effect on general health behavior. These results highlight the role that general physical health and mental health play on precautionary behavior and the critical importance of addressing issues such as depression, general health behaviors, and impulsivity in promoting safe actions and the protection of self and others.

RESUMO

Abstract From the perspective of positive environment theory, supportive environments, can promote student successful academic adaptation. Accordingly, student academic success is the result of academic adaptation, and can be assessed via means of academic engagement and self-regulated learning. Thus, the aim of the present study was to test the relationship between positive learning environments (POLE), academic engagement and self-regulated learning in high school students. Using a cross-sectional design, participants included 166 freshmen high school students, 76 participants of the sample were male (45.8%) and 90 were female (54.2%). Mean age was 15.2 (S.D. = .43). Before participation informed consent was obtained from parents and assent from participants. Students answered a questionnaire regarding academic support given by parents, pro-academic friends, positive family environment, and academic engagement and self-regulated learning. Using Structural Equation Modeling the results demonstrated (p<.05) that POLE represented a latent factor formed by parental academic support, pro-academic friends and positive family environment. The structural model showed that POLE was positively related to academic engagement (structural coefficient= .80); also, academic engagement was related with self-regulated learning (structural coefficient= .55) and explained 30% of student self-regulated learning. Results suggest that POLE could promote academic engagement and self-regulated learning.

Resumen De acuerdo con la teoría de ambientes positivos, los contextos donde se brinda apoyo académico pueden promover la adaptación exitosa de los estudiantes, y, a su vez, el resultado de dicha adaptación favorece su éxito académico, lo cual puede medirse con los constructos de compromiso académico y aprendizaje autorregulado en el ámbito académico. Teniendo esto en consideración, en la presente investigación se da cuenta de un trabajo de psicología positiva aplicada en el que se tuvo como objetivo evaluar la relación entre el ambiente de aprendizaje positivo (AAP), el compromiso académico y el aprendizaje autorregulado en bachilleres mexicanos. Para esto, se diseñó un estudio de tipo correlacional en el que participaron 166 estudiantes voluntarios de primer grado de bachillerato, seleccionados por conglomerados, con consentimiento informado individual y de sus padres. Del total de participantes, 76 fueron de sexo masculino (45.8 %) y 90 de sexo femenino (54.2 %), con una edad promedio de 15.2 años (DE = .43); quienes respondieron a cuestionarios sobre apoyo académico de padres, amigos pro-académicos, ambiente familiar positivo, compromiso académico y aprendizaje autorregulado. Se realizó un análisis de ecuaciones estructurales, y en los resultados se encontró, con una p < .05, que el AAP fue un factor latente formado por el apoyo académico de los padres, los amigos pro-académicos y el ambiente familiar positivo; además, en el modelo estructural, el AAP correlacionó positivamente con el compromiso académico (coeficiente estructural = .80), y este último se relacionó positivamente con el aprendizaje autorregulado de los estudiantes (coeficiente estructural = .55); finalmente el modelo estructural resultante explicó el 30 % del aprendizaje autorregulado. Para concluir, se discute respecto a la posibilidad de que el AAP promueva el compromiso académico y el aprendizaje autorregulado de los estudiantes.
