Objective: To know if there is a significant difference between the types of maternal vs. paternal parental socialization and if they are predictors of suicidal ideation in students of  Ignacio Carrillo Franco (ICF) Preparatory School, May 2017.  Material and methods: Observational, transversal, prospective study. The studiend population was the high school students ICF. The parental socialization styles of both parents were measured using the ESPA-29 scale and the suicidal ideation (Roberts scale) of the students. Descriptive and inferential statistics were performed using ANOVA and multiple linear regression with the IBM SPSS Statistics 20 program.  Results: There were 144 students, aged 15-17 (m16.31 ± SD 0.68). The maternal parental socialization style (Negligent vs Authoritarian Games-Howell m: 1.84, SD 0.57, Sig .011) shows significant difference vs paternal and maternal axes Acceptance/Implication (t: -2.85, Sig .005), Coercion/ Imposition (t 3.35, Sig .001), maternal dysplication (t 5.913, Sig .000) and paternal (t 3.343, Sig 0.001) are predictors of suicidal ideation.  Discussion: The mother plays the most important role in the suicidal ideation of adolescents; since according to their parental style they are the most predicted.  Key words: Styles of parental socialization, suicidal ideation, adolescents.

ABSTRACT Objective The study aims to identify the nutritional habits of second-year high school students in Seferihisar, Turkey, and the factors associated thereof, based on the Ecological Framework. Methods In this cross-sectional study by a self-reported questionnaire, second-year high school students (n=392) attending public schools in Seferihisar had their nutritional habits measured with the Adolescent Food Habits Checklist scale. The food habit score was calculated and associated factors were evaluated in 4 layers based on the Mary Story’s Ecological Framework (individual factors, social, physical and macro-level environments). The data analysis for the association of these layers with the food habits score was executed through multi-level linear regression. Results Students’ participation rate was 87.7% (n=344). Of all the layers (from individual factors to the influence of the social environment and macro-level environment: nutritional literacy, the food consumption of their peers at school, availability of fruits-vegetables at home, buying junk food at the school canteen, presence of posters at school, etc.), the option for advertised food items was statistically explanatory based on the linear regression analysis (p<0.05). Conclusions The model derived from the Ecological Framework explained 45% of the nutritional habits with an equivalent contribution from the four layers. Availability of healthy food items where the students lived and higher levels of nutritional literacy led to healthy nutritional habits. Having healthy food items sold at school canteens at affordable prices, using posters to promote a healthy diet, and introducing nutrition-related courses into the curricula would support students in developing healthy nutritional habits.

This study aims to determine the effect of self-efficacy on the learning achievement of biology class X students in Namlea district. This type of research is ex-post facto which is causality designed to explain the existence of a causal relationship between variables. The population in this study amounted to 603 students of State Senior High School in Namlea district. The sample in this study amounted to 90 students. The data analysis technique used simple linear regression analysis.The results of the analysis show that self-efficacy has a positive and significant effect on the biology learning achievement of class X SMA Negeri in Namlea sub-district. Judging from the results of simple linear regression calculations, it can be seen that the magnitude of the influence is 0.271.While the R square value is 0.036. So it can be seen that the relative contribution of the effect of self-efficacy on learning achievement is 36.0%, while 64% is influenced by other variables not examined in the study.

Abstract Background Lower health literacy (HL) has been known to be involved in a range of common mental and physical disorders among adolescent students. Ample studies indicated low HL is associated with a series of chronic diseases even psychological diseases, nevertheless, little is known about this relationship among adolescents. In this context, the study aimed to examine associations between psychosomatic symptoms (physical and psychological symptoms) and HL in junior and senior high school students in China, and to provide guidance for improving the physical and mental health in Chinese adolescents. Methods A total of 22,628 junior and high school students in China were enrolled in this study. HL and psychosomatic symptoms were measured by self-report validated questionnaires. Multiple linear regression analyses were conducted to examine the associations between six sub-scales of HL and physical / psychological symptoms. Results Multiple linear regression analysis demonstrated that the sub-scales of HL showed a significantly negative association with physical symptoms and psychological symptoms (P <  0.05 for each). Physical symptoms was most strongly associated with IR (β = − 0.134), followed by SM (β = − 0.093), DB (β = − 0.059), SA (β = − 0.058) and PA (β = − 0.054). No statistically significant difference was found between HA and physical symptoms (P > 0.05). Meanwhile, psychological symptoms were most strongly associated with IR (β = − 0.160), followed by SA (β = − 0.129), SM (β = − 0.069), DB (β = − 0.031), HA (β = − 0.026) and PA (β = − 0.021). Conclusion These results indicated the importance of identifying the association of HL with physical and psychological symptoms, and provided the evidence that lower HL may serve as a critical and independent risk factor for poor health outcomes. Meanwhile, to maintain students’ desirable healthy status public health efforts for enhancing their HL level are urgently needed in adolescents.

Summary: This article describes a triarchic analysis of an aptitude-treatment interaction in a college-level introductory-psychology course given to selected high-school students. Of the 326 total participants, 199 were selected to be high in analytical, creative, or practical abilities, or in all three abilities, or in none of the three abilities. The selected students were placed in a course that either well matched or did not match their pattern of analytical, creative, and practical abilities. All students were assessed for memory, analytical, creative, and practical achievement. The data showed an aptitude-treatment interaction between students' varied ability patterns and the match or mismatch of these abilities to the different instructional groups.
