This study analyses the prevalence of sexting and the reasons and attitudes associated with its practice in adolescents with different cultural backgrounds (Colombia and Spain). The sample is made up of 489 Spaniards and 510 Colombians aged between 13 and 18 years. The results show that sexting is strongly influenced by gender and the country, in favor of men and Colombians respectively. The interaction between gender and country establishes that in Spain women and men practice sexting equally, while in Colombia men practice much more sexting than women. Although the practice of sexting increases progressively with age, the levels are higher among Colombian adolescents, especially after 15 years. According to the results, although both groups present a high risk for sexting, socio-cultural aspects and gender constitute differential variables to be taken into consideration. Therefore, it is necessary to design preventive strategies including cultural differences in relation to the sexuality.  相似文献

ABSTRACT

The aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time.  相似文献

新冠肺炎疫情的持续蔓延为儿童青少年的发展带来了风险。积极心理学强调人类自身的潜能、美德、积极情绪等对个体发展的意义,通过使用预防性心理保健帮助个体适应环境,儿童青少年获得积极发展后,能对个人、家庭、社区及人类社会做出积极的贡献,并大大降低出现问题行为和罹患精神疾病的风险,与儿童青少年在常态化疫情防控下的发展需求相契合。本文通过对儿童青少年积极发展这一概念的探讨,提出为应对疫情常态化,应注重复原力和社会参与意识及行为的培养,并从个体、家庭、学校和社区等多个维度构建社会支持系统,开展心理健康教育,加强重点人群心理监测与干预,以促进儿童青少年的积极发展。  相似文献

The present study examined associations between boys’ and girls’ self-reported psychological adjustment and a wide spectrum of peer-rated behaviours in the school context using a sample of 463 Estonian early adolescents (Mage = 12.90). Although girls had more internalised problems and boys more externalised problems, the associations between adolescents’ psychological adjustment and behaviour were not gender-specific. Among both boys and girls, hostility was positively associated not only with their peer-reported misbehaviour, but also with sociable behaviour and negatively with studiousness. Adolescents with negative self-esteem were perceived to exhibit high levels of self-centred competitive behaviour, misbehaviour and also sociable behaviour. Those with negative self-adequacy, on the contrary, were less likely to behave in a self-centred competitive and sociable manner. In general, the findings show that psychological maladjustment may appear not only in well-observed problematic behaviour but also in seemingly ordinary behaviour in school.  相似文献

Following the recommendations of Lent, Brown and Hackett's Social Cognitive Career Theory (2000), we measured eighth grade boys' and girls' perception of the proportion of men and women employed in occupations and their level of interest and self-efficacy for those occupations. Results indicated that eighth grade boys and girls expressed stronger career interest in and higher self-efficacy for those occupations that they rated as employing more of their own gender. The study highlights how career practitioners can work with adolescents to widen their perceived range of occupational choices.  相似文献

An estimated 20% of all adolescents will experience a depressive disorder by the age of 18, with schools being at the forefront of initiatives to promote resilience and well-being. This study reports on the development of the 24-item Student Perception of Wellbeing Questionnaire (SPWQ), created as a measure of well-being in three areas: exercise, explanatory style, and conflict resolution. The SPWQ was administered to 235 male school students from Years 6–8 and 251 female students from Years 7–9, and a principal components analysis with varimax rotation was performed on the data obtained. A three-factor solution was identified dealing with explanatory style, conflict resolution, and exercise, which explained 31% of the total variance. The scale was found to have strong internal consistency with a Cronbach alpha coefficient of α = 0.80 for the male students and α = 0.84 for the female students.  相似文献

Cyberbullying is a major health concern for today's youth and a pervasive stressor for adolescents and their families. This study offers qualitative insights into how parents perceive their children's technology use and engagement in cyberbullying based on gender. Eight focus groups were conducted with 48 parents of adolescents ages 10–17. Findings indicated parents perceived their children overuse technology and lack awareness of what cyberbullying is. Specific to gender, parents suggested their daughters use technology for social connection, and parents were more concerned about their daughter's technology use than their son's, which they believed was related to specific interests. In response to cyberbullying scenarios, parents encouraged females but not males to socialize with peers. This is the first qualitative study to obtain an in-depth understanding of the ways in which parents perceive and socialize their children in regard to technology use and cyberbullying scenarios. These results may help school systems, school psychologists, researchers, and parents gain awareness of the gender-stereotypical socialization process that unfolds in parental monitoring of technology use and cyberbullying situations. We conclude by offering suggestions for how school systems and personnel might intervene.  相似文献
