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…
Adverse Social Experiences in Adolescent Rats Result in Enduring Effects on Social Competence, Pain Sensitivity and Endocannabinoid Signaling
2016
Abstract: Social affiliation is essential for many species and gains significant importance during adolescence. Disturbances in social affiliation, in particular social rejection experiences during adolescence, affect an individual's well-being and are involved in the emergence of psychiatric disorders. The underlying mechanisms are still unknown, partly because of a lack of valid animal models. By using a novel animal model for social peer rejection, which compromises adolescent rats in their ability to appropriately engage in playful activities, here we report on persistent impairments in social behavior and dysregulations in the endocannabinoid (eCB) system. From postnatal day (pd) 21 to…
Genetic association study of childhood aggression across raters, instruments, and age
2021
AbstractChildhood aggressive behavior (AGG) has a substantial heritability of around 50%. Here we present a genome-wide association meta-analysis (GWAMA) of childhood AGG, in which all phenotype measures across childhood ages from multiple assessors were included. We analyzed phenotype assessments for a total of 328 935 observations from 87 485 children aged between 1.5 and 18 years, while accounting for sample overlap. We also meta-analyzed within subsets of the data, i.e., within rater, instrument and age. SNP-heritability for the overall meta-analysis (AGGoverall) was 3.31% (SE = 0.0038). We found no genome-wide significant SNPs for AGGoverall. The gene-based analysis returned three sign…
Binge-like ethanol treatment in adolescence impairs autophagy and hinders synaptic maturation: Role of TLR4.
2018
Abstract Adolescence is a developmental period of brain maturation in which remodeling and changes in synaptic plasticity and neural connectivity take place in some brain regions. A different mechanism participates in adolescent brain maturation, including autophagy processes that play a role in synaptic development and plasticity. Alcohol is a neurotoxic compound whose abuse in adolescence causes TLR4 response activation by triggering neuroinflammation, neural damage and behavioral alterations. However, the potential participation of autophagy in long-term neurochemical and cognitive dysfunctions induced by binge ethanol drinking in adolescence is uncertain. We therefore evaluated whether …
The Interplay between Genes and Psychosocial Home Environment on Physical Activity
2018
Introduction Genetic factors contribute to individual differences in physical activity, but it remains uncertain whether the magnitude of the genetic effects is modified by variations in home environments. We aimed to examine to what extent the psychosocial home environment in childhood and adolescence modifies the genetic influences on leisure time physical activity in young adulthood. Methods Participants were Finnish twins (N = 3305) who reported their leisure time physical activity at age 24 yr. The psychosocial home environment was assessed by twins at ages 12, 14, and 17 yr, as well as by their parents when the twins were age 12 yr. Gene–environment interaction modeling was performed …
Psychological predictors of homophobic bullying among adolescents and young adults: The role of parental psychological control and sensation seeking
2021
AbstractWe aimed to investigate the relationship between homophobic bullying, parental psychological control and sensation seeking among adolescents and young adults and to examine the mediating role of sensation seeking. The participants included 394 adolescents and young adults aged 15 to 20 years attending the 3rd, 4th and 5th years of two public high schools in Italian cities. Participants completed the Homophobic Bullying Scale, the Dependency—oriented and Achievement—oriented Parental Psychological Control, and the Sensation—Seeking Scale. The results showed that parental psychological control predicted bullying toward gay and lesbian people. However, the two dimensions of sensation s…
Self-image and psychological distress in treatment-seeking adolescents
2017
Background: Adolescence has been recognized as a critical period for mental health during which it is fundamental to the well-being of adolescents to provide early and appropriate mental health interventions. Self-image perceptions play a particularly relevant role during adolescence since individuals are extensively involved in reorganizing their identity and relationships. Although the self-image development implies adaptive outcomes for most adolescents, some age-related tasks can be difficult to deal with and lead to psychological suffering for a minority of them. Method: This study examined how domain-specific self-image was associated with psychological distress in 128 treatment-seeki…
Identity profiles and digital engagement among Finnish high school students
2018
Developing a stable personal identity is considered a more precarious task in today’s society than hitherto. Skilful digital engagement may, however, constitute a valuable asset in necessary identity exploration and commitment. Applying a person-oriented approach, we examined for the first time how identity profiles are associated with digital engagement, operationalized as digital competence, gaming seriousness, type of internet activity and excessive ICT use. After controlling for gender, life satisfaction and parental SES, this study of a Finnish high school sample (N = 932) revealed that adolescents with future commitments and some exploration of options (achievement, searching moratori…
Relació entre esports d’equip i empatia en l’adolescència
2018
L’empatia és la capacitat de posar-se en el lloc d’un altre individu i interpretar la realitat des del seu punt de vista. Aquest estudi es va centrar a analitzar les diferències existents entre practicants d’esports d’equip i esports individuals i entre homes i dones en empatia. La mostra va estar composta per 97 adolescents federats més d’un any, dels quals 43 eren dones i 54 eren homes. 25 practicaven esport individual i 72 algun esport d’equip. Els resultats obtinguts en l’escala d’empatia de Baron-Cohen –EQ–, han mostrat que els practicants d’esports d’equip són més empàtics que els d’esports individuals, i que les dones ho són més que els homes. No obstant això, seria convenient realit…
Prevención del acoso en adolescentesa través de las nuevas tecnologías de información y comunicación: Programa Prev@cib
2018
Antecedentes: El cyberbullying se define como una conducta agresiva e intencional que se repite de forma frecuente en el tiempo mediante el uso, por un individuo o grupo, de dispositivos electrónicos sobre una víctima que no puede defenderse por sí misma fácilmente. Los estudios evidencian un aumento en la prevalencia del cyberbullying que afecta cada vez a niños y adolescentes más jóvenes. La preocupación social mundial que surge de este creciente problema revela la necesidad de desarrollar programas que disminuyan y prevengan el ciberacoso. Objetivos: El objetivo principal de esta tesis doctoral fue diseñar, implementar y evaluar un programa de prevención del cyberbullying llamado Prev@ci…
