Effects of acute bupropion administration on locomotor activity in adolescent and adult mice
2005
Responses to some psychoactive substances seem to differ between adolescents and adults. Bupropion, an antidepressant which is also used for smoking cessation, induces a dose-dependent increase in locomotor activity in adult mice, although its behavioral actions in adolescents have not been evaluated. In the present study the effects of acute bupropion administration (5, 10, 15 and 20 mg/kg) on locomotor activity were examined in early adolescent (postnatal day (pnd): 29-31 days), late adolescent (pnd: 47-49 days) and adult (pnd > 70 days) male NMRI mice, using an infrared photocell system. Locomotion was recorded for a total period of 90 min. Results indicated that there were significant d…
Relationships between affective states and childhood internalizing disorders
2018
Internalizing disorders are mainly defined as psychosomatic, anxiety and depression problems. The aim of this study was to analyze the relationships between dairy affective states and internalizing disorders in early adolescence (10–12 years old), considering the influence of sex. The participants of the study were 367 children aged between 10 and 12 (190 girls and 177 boys). The results showed that fear was the best predictor for all internalizing disorders, and the only common predictor for all of them. The prediction of boys' internalizing disorders was based only in fear, whereas the prediction for girls involved more variables besides fear. An early detection/regulation of these affect…
Associations between Adolescents’ Interpersonal Relationships, School Well-being, and Academic Achievement during Educational Transitions
2020
AbstractA youth’s ability to adapt during educational transitions has long-term, positive impacts on their academic achievement and mental health. Although supportive relationships with parents, peers, and teachers are protective factors associated with successful educational transitions, little is known about the reciprocal link between the quality of these interpersonal relationships and school well-being, with even less known about how these two constructs affect academic achievement. This longitudinal study examined how the quality of interpersonal relationships and school well-being worked together to affect academic achievement during the transition from primary school to lower second…
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…
Effects of an intervention program (HHP) on the promotion of healthy habits in early adolescence
2015
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.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).the IHH obtained good reliability, Interclass Correlation Coefficient (range .506 - 884; p.001) and Spearman Correla…
Influence of beliefs about romantic love on the justification of abusive behaviors among early adolescents
2021
Introduction Romantic experiences during adolescence have an important influence on functioning later in life. Romantic love has been associated with the acceptance of abusive behaviors. This study examined the relationship between myths of romantic love and the perceived severity of different types of abusive behaviors, as well as the influence of gender. Methods The sample comprised 448 Spanish adolescents (M = 12.92 years old; SD = 0.85), of which 50.3% were male and 49.7% were female. Participants were evaluated in the school setting. The Perception of Abuse Scale and the Myths, Fallacies, and Misconceptions about Romantic Love Scale were administered. Results Statistically significant …
Analysis of the Relationship between Tobacco Smoking and Physical Activity in Adolescence: A Gender Specific Study
2021
Background and Objective: Although smoking and the physical activity level (PAL) are important determinants of health status in adolescence, there is a lack of information on the relationship between smoking and PAL in early adolescence. The objective of this study was to evaluate the gender-specific relationship between smoking and PAL in 14-to-16-year-old adolescents. Materials and Methods: The sample included 650 adolescents (337 girls, 14.7 ± 0.5 years at first testing wave) from Bosnia and Herzegovina. During the first testing wave, participants were tested using structured questionnaires. Second testing was commenced after approximately 20 months (16.4 ± 0.6 years). The variables were…
Internalizing problems as a mediator in the relationship between low effortful control and internet abuse in adolescence: A three-wave longitudinal s…
2019
Abstract The aim of the study is to examine the relationships between early adolescents' low effortful control, middle adolescents' internalizing problems and late adolescents' Internet abuse, focusing on the mediating role that middle adolescents' internalizing problems may play in the relationship between early adolescents' low effortful control and late adolescents' Internet abuse. The study followed a sample of 482 adolescents (245 boys and 237 girls) from early adolescence (wave 1; mean age = 14.76, SD = 0.63), through middle adolescence (wave 2; mean age = 15.77, SD = 0.61), to late adolescence (wave 3; mean age = 17.88, SD = 0.57). The participants completed self-report questionnaire…
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…
Problem behavior as a precursor of male criminality
1996
AbstractThe participants (originally 196 boys and 173 girls) in an ongoing longitudinal study were examined using peer nomination and teacher rating at ages 8 and 14 years. Criminal records were collected at age 27 years. The results showed that (a) criminal offenses were best predicted if the accumulation of behavior problems over the school years was considered; (b) the risk for different types of offenses was highest for boys who exhibited escalating conduct problems and school failure over the school years; (c) norm-breaking behavior in early adolescence was strongly related to a propensity to later criminal offenses; (d) childhood aggressiveness did not predict arrests without the pres…
