Motor Competence and Health-related Fitness of School-Age Children: A Two-Year Latent Transition Analysis

2021

PURPOSE The aims of this study were twofold: 1) to identify latent physical performance profiles of motor competence (MC) and cardiorespiratory (CF) and muscular fitness (MF) among school-age children and 2) explore transition probabilities in physical performance profiles over a 2-yr period. METHODS The present sample comprised 1148 (583 girls, 565 boys) elementary school students (baseline Mage = 11.27 ± 0.32), and data were collected annually (equal intervals) over a period of 2 yr which resulted in a total of three measurements. The measures used were the throwing-catching combination test, 5-leaps and two-legged jumps from side-to-side test (MC), 20-meter shuttle run test (CF), and cur…

Longitudinal and situational associations between math anxiety and performance among early adolescents

2022

Studies have found math anxiety and achievement to be related from the beginning of formal schooling, but the knowledge regarding the direction of the relationship is vague. The purpose of the present study was to study this relationship. We investigated math anxiety from two points of view: trait and state anxiety. In the first substudy, we investigated the longitudinal relationship between math anxiety and performance from sixth to seventh grade (n = 848) with cross-lagged modeling. In the second substudy, we investigated the situational relationship of anxiety and performance by giving the participants (n = 149) challenging and nonchallenging math tasks adapted to their skill level, and …

The Relationship among Paternal and Maternal Psychological Control, Self-Esteem, and Indecisiveness across Adolescent Genders

2015

The purpose of this study was to examine the relationship among adolescents’ indecisiveness, adolescents’ self-esteem, and maternal and paternal psychological control by focusing on the differences in the relationship among these variables across adolescent genders. A total of 381 Italian adolescents (215 boys and 166 girls), aged from 13 to 17 years, completed self-report measures of parental psychological control, self-esteem and indecisiveness. Since previous studies have highlighted indirect relations between family characteristics and indecisiveness, structural equation modeling (SEM) methods were used for testing self-esteem as a possible mediator. In particular, a multiple group anal…

2015

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…

Change, Reliability, and Stability in Self-perceptions in Early Adolescence: A Four-year Follow-up Study

1995

Changes in self-perceptions of fitness, appearance, and self-esteem among adolescents were assessed in a 4-year follow-up study. Both the changes in the mean levels across time (profile analysis), and the changes in the reliability and stability of individual differences (i.e. covariance stability as test-retest correlations) were examined. The subjects (64 boys, 49 girls) were 11 years old at the first annual measurement. Self-esteem was assessed using the Rosenberg Self-Esteem Scale, as well as self-assessment questionnaires specifically designed for this study to assess Perceived Fitness and Perceived Appearance. MANOVA-and Simplex-models were used in the analysis. Our results among the…

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…

Efectos de un programa de intervención (PHS) para la mejora de los hábitos saludables en la primera adolescencia

2015

Background: it is vital to monitor and promote healthy lifestyle habits in early adolescence, as it is a time of changes when future lifestyle habits are formed. Methods: a study was conducted to find out the effects of a Healthy Habits Program (HHP) in children between the ages of 10 and 12 years (N = 158). The study included an intervention group (IG) (n = 90), which participated in the HHP for 8 months, and a control group (CG) (n = 100). In order to assess healthy habits in these children we used the Inventory of Healthy Habits (IHH), the reliability of which was previously evaluated (N = 134). Results: the IHH obtained good reliability, Interclass Correlation Coefficient (range .506 - …

CHANGES IN SCHOOL ANXIETY AND EMOTIONAL SELF-REGULATION OF AN ADOLESCENCE EXPERIMENTAL GROUP FOLLOWING THE ABKT-B PROGRAMME

2020

The purpose of this study was to adapt the experimental programme MBCT-C (Randy J. Semple & Jennifer Lee’s programme “Mindfulness-Based Cognitive Therapy for Anxious Children”, 2011) in early adolescents and compare the changes in school anxiety and emotional regulation indicators before and after in the experimental and control group. The necessity for intervention with respect to school anxiety and emotional regulation among children with emotional regulation and school anxiety issues in the early adolescence group was indicated by research into problems connected with youth behaviour and difficulties in regulating emotions. The study analysed the results of six 6th grade students (12…

Cannabis Use and the Risk for Psychosis and Affective Disorders.

2019

Objective: This review discusses the relationship between cannabis use and psychotic, bipolar, depressive, and anxiety disorders, as well as suicide. It summarizes epidemiological evidence from cross-sectional and long-term prospective studies and considers possible etiological mechanisms. Methods: Systematic reviews and methodologically robust studies in the field (from inception to February 2019) were identified using a comprehensive search of Medline, PsychINFO, and Embase and summarized using a narrative synthesis. Results: Consistent evidence, both from observational and experimental studies, has confirmed the important role of cannabis use in the initiation and persistence of psychoti…
