The Relationship between Self-Esteem, Depression and Anxiety: Comparing Vulnerability and Scar Model in the Italian Context

2016

Abstract Background: The relationship between low self-esteem and depression and anxiety disorders has solicited a growing body of empirical research. The most important explanation models are two: the vulnerability model states that low self-esteem is a risk factor for depression and anxiety, and the scar model states that low self-esteem is an outcome, not a cause, of depression and anxiety. Method: In the present research we tested the two different models using a sample of Italian preadolescent, aged 11 to 14 years, recruited from an Italian secondary school. To test the models, the path analysis technique was used: one in which self-esteem predicted anxiety and depression (Model 1), an…

El consumo de sustancias psicoactivas en la adolescencia temprana y media. El papel de la eficacia académica y de la crianza

2020

ABSTRACT This study examines (i) the relationships between substance use and parenting style and between substance use and perceived academic self-efficacy in early and middle adolescence, (ii) the importance of these factors in predicting adolescent substance use, and (iii) the role of academic self-efficacy in the relationship between parenting styles and adolescent substance use. The sample comprised 762 adolescents (53% boys) aged 12 to 16 years (M = 13.66, SD = 1.34). The sample was selected using probabilistic cluster sampling according to type of school (secondary, public vs. semi-private) and school location in different areas of the city of Valencia (Spain). This approach accounted…

Substance Use in Early and Middle Adolescence. The Role of Academic Efficacy and Parenting

2019

espanolLos objetivos de esta investigacion son analizar la relacion del consumo de sustancias con el estilo de crianza de los padres y la percepcion de eficacia academica por parte de los adolescentes, estudiar la diferente contribucion de estos factores a la prediccion del consumo de sustancias en la adolescencia y observar la funcion de la autoeficacia academica en la relacion entre el estilo de crianza y el consumo de sustancias en la adolescencia. Participaron 762 adolescentes (53% hombres), de edades comprendidas entre los 12 y los 16 anos (M = 13.66, DT = 1.34). La muestra se selecciono con criterios probabilisticos por conglomerados, atendiendo al tipo de centro (educacion secundaria…

The presence of a woman increases testosterone in aggressive dominant men

2008

In line with the challenge hypothesis, this study investigated the effects of the presence of a woman on the testosterone (T) levels of young men. An informal contact with a woman of approximately 5 min resulted in an increase in salivary T among men. These effects occurred particularly in men with an aggressive dominant personality. In addition, higher salivary T levels were related to a more aggressively dominant personality, being sexual inactive for a month or more, and not being involved in a committed, romantic relationship. The most important findings of this study are that the short presence of a woman induces specific hormonal reactions in men, and that these effects are stronger f…

Hereditary Progressive Mucinous Histiocytosis in Women

1988

We describe three female patients in a family of two generations, who suffered from generalized and maximally pea-sized histiocytic tumors beginning in early adolescence. The disease ran a uniform and slowly progressive course and was confined to the skin. There were no signs of spontaneous tumor regression. Histologic, immunohistochemical, and ultrastructural examination revealed the histiocytic nature of the tumors. An outstanding finding was a marked production of mucinous material, predominantly in long-standing tumors. This nonlangerhansian syndrome differs from other benign normolipemic histiocytic diseases with generalized histiocytic tumors by inheritance, which is most likely autos…

Recent evidence suggests a rather gradual developmental trajectory for processing vertical relational face information, lasting well into late adolescence (de Heering and Schlitz, 2012). Results from another recent study (Tanaka et al., 2014) indicate that children and young adolescents use a smaller spatial integration field for faces than do adults, which particularly affects assessment of long-range vertical relations. Here we studied sensitivity to replacement of eyes and eyebrows (F), variation of inter-eye distance (H) and eye height (V) in young adolescents (11-12 years), young (21-25 years) and middle-age adults (51-62 years). In order to provide a baseline for potential age effects…

School grades as predictors of self-esteem and changes in internalizing problems: A longitudinal study from fourth through seventh grade

2020

This longitudinal study of 562 students (from ages 10 to 13) investigated whether developmental changes in internalizing problems (emotional and peer problems) can be predicted by school grades in mathematics and language arts and whether these predictive relations are mediated by students' self-esteem. The data comprised of teacher-rated internalizing problems, grades in math and language arts, and student self-ratings of self-esteem. The latent change score modeling indicated that math grades positively predicted self-esteem. Furthermore, lower self-esteem was related to an increase in internalizing and emotional problems in the total sample, and to an increase in peer problems in boys. T…

Does Stress Mediate the Association Between Emotional Intelligence and Life Satisfaction During Adolescence?

2019

Background Based on Mayer and Salovey's model of emotional intelligence, this study examined whether perceived stress mediates the interplay of emotional intelligence and life satisfaction for girls and boys during early and middle adolescence. Methods Using multigroup structural equation modeling with questionnaire data from a sample of Spanish adolescent students (N = 800; MAge T1 = 14.02, MAge T2 = 15.00, SD = 1.21) in 2 waves (T1 = March 2015; T2 = December 2015). Results Results of multigroup structural equation modeling indicated no group differences between boys and girls in early adolescence (7th and 8th grade) and middle adolescence (9th and 10th grade), as stress function as media…

Genetic and environmental effects on body mass index during adolescence: a prospective study among Finnish twins

2009

To study genetic and environmental factors affecting body mass index (BMI) and BMI phenotypic correlations across adolescence. Prospective, population-based, twin cohort study. We used twin modeling in 2413 monozygotic and same-sex and opposite-sex dizygotic Finnish twin pairs born in 1983–1987 and assessed using self-report questionnaires at 11–12, 14 and 17 years of age. Heritability of BMI was estimated to be 0.58–0.69 among 11–12- and 14-year-old boys and girls, 0.83 among 17-year-old boys and 0.74 among 17-year-old girls. Common environmental effects shared by siblings were 0.15–0.24 among 11–12- and 14-year-old boys and girls but no longer discernible at 17 years of age. Unique enviro…

The Impact of Abuse and Learning Difficulties on Emotion Understanding in Late Childhood and Early Adolescence

2014

Children's affective experiences and cognitive abilities have an impact on emotion understanding. However, their relative contribution, as well as the possibility of an interaction between them, has rarely been examined. The aim of the present study was to evaluate the influence of severe abuse and learning difficulties on simple and complex components of emotion understanding in late childhood and early adolescence. A total of 28 older children and young adolescents were selected for the study. Half of the participants had suffered from severe abuse, and half of these abused children additionally had learning disabilities. The remaining half of the sample had no history of abuse but were m…
