本研究采用问卷法,以1060名五至八年级学生为被试,考察了家庭功能如何通过同伴接纳的中介作用影响亲社会行为,同时探讨了留守状况在该中介模型中所起的调节作用。结果发现:(1)青少年的家庭功能、同伴接纳和亲社会行为两两之间呈显著正相关;(2)青少年的同伴接纳在家庭功能及亲社会行为中起部分中介作用;(3)留守状况调节了家庭功能通过同伴接纳影响亲社会行为的后半段路径。具体而言,与曾/现留守青少年相比,非留守青少年的家庭功能通过同伴接纳对亲社会行为产生的影响更强。研究结果可以为培养青少年的亲社会行为提供参考价值。 相似文献

采用事件相关电位(ERP)研究技术,运用剑桥风险任务的实验范式,考察了青少年风险决策的时程加工机制。行为结果表明,在高、中、低三种不确定性条件下,相对于效价,被试的决策更多的关注概率。脑电结果显示:1)不确定性的主效应在N400上表现显著,高不确定条件和中不确定条件的波幅要明显大于低不确定性条件的波幅,而高不确定条件和中不确定条件的波幅无显著差异;2)与中不确定条件相比,高不确定条件和低不确定条件诱发了一个新异正成分(LPC),高不确定条件和低不确定条件的波幅要明显大于中不确定性条件的波幅,而高不确定条件和低不确定条件的波幅无显著差异。青少年在风险任务中的决策较多的是选择安全选项,表现出较为明显的风险规避倾向。N400的波幅可能反映了不确定性程度,而LPC的波幅大小可能反映了结果评价准确性程度的高低。 相似文献

青少年疏离感与病理性互联网使用的关系:家庭功能和同伴接纳的调节效应检验 总被引:1,自引:0,他引:1
通过对549名初一至高二年级城市青少年的问卷调查, 考察了青少年病理性互联网使用的特点及其与疏离感之间的关系, 并对家庭功能和同伴接纳是否可以调节疏离感与病理性互联网使用之间的关系进行了检验。结果发现:(1)在所有使用互联网的青少年被试中, 网络成瘾群体的检出率为8.93%; (2)女青少年病理性互联网使用的突显性水平高于男青少年。在病理性互联网使用的消极后果上, 初一青少年高于高一、初三和高二青少年。但青少年病理性互联网使用总体上不存在显著的性别和年级差异; (3)疏离感较高的青少年病理性互联网使用的水平也较高, 健康的家庭功能可以保护疏离感高的青少年减少病理性互联网使用, 但同伴接纳对高疏离感青少年减少病理性互联网使用不具有保护性作用。 相似文献

This study examined how parent-adolescent relationships are related to adolescent loneliness, interpersonal difficulties and school adjustment among Israeli Arabs. Two hundred and thirty-one 11th graders (103 boys and 128 girls) and their homeroom teachers participated. Four groups of adolescents were identified according to parenting practice profiles: Adolescents in the harsh parenting group reported the highest levels of loneliness, those in the distant and mixed groups reported midway levels of loneliness, and those in the warm group showed the lowest degree of loneliness and the lowest levels of interpersonal problems. Overall, boys reported higher levels of peer-related loneliness and lower levels of affinity for aloneness than girls. Gender interacted significantly with parenting group, with girls in the harsh parenting group exhibiting greater parent-related loneliness and affinity for loneliness, while boys exhibited more peer-related loneliness. The important role that parents play in their children's social adjustment is discussed in relation to gender and culture. 相似文献

Although numerous investigations of overt aggressive and antisocial trajectories have been undertaken, there is a dearth of literature examining gender differences and similarities in trajectory patterns and their correlates. To address these gaps, we investigated gender differences in the prevalence rates, predictive validity during transition to adulthood, childhood risk factors, and adolescent correlates of different trajectories of teacher-reported overt aggression (i.e., fights, argues, gets in trouble) among 220 participants (116 girls and 104 boys) evaluated annually from grade 4 to grade 12. Four patterns of trajectories were identified: low, increasing (i.e., adolescent-onset), decreasing (i.e., childhood-limited), and high (i.e., childhood-onset). A large proportion of youth, particularly girls, displayed low levels of aggression over time. A small proportion followed the childhood-onset trajectory. Across gender, the childhood-onset trajectory was associated with the highest rates of maladjustment during the transition to adulthood, the highest number of childhood risk factors, and multiple problems during adolescence. The adolescent-onset trajectory was associated with few childhood risk factors, but with high levels of independent status during adolescence. In contrast, the childhood-limited trajectory was associated with several childhood risk factors, but high levels of parental monitoring and school engagement during adolescence. Romantic involvement differentiated the adolescent-onset and childhood-limited trajectories among girls. 相似文献

The present study examined adolescents' experiences of loneliness and solitude in their responses to an online survey on self-care. Both quantitative (n = 272) and qualitative (n = 150) responses were coded for these feelings when home alone. Results indicate that adolescents experience the duality of aloneness, including both positive solitude and negative loneliness. Adolescents' responses range from embraced solitude and self-care to feelings of loneliness and rejection of time by themselves. Adolescents reporting loneliness were significantly less likely to enjoy being home alone during the day and at night (p < or = .001). Also, gender, age, and emotions such as fear, boredom, and separation anxiety are associated with loneliness among adolescents in self-care. Interventions to increase connectedness and combat loneliness during out-of-school hours are recommended. 相似文献

目的:采用大数据技术与质性分析相结合的方式,探索疫情期间青少年长时间与父母相处的条件下,亲子冲突的演变特征。方法:利用Python3.8编写程序,以“亲子冲突、初中生、高中生、青少年、冲突、父母、与父母冲突”等为关键词在微博平台上搜索个人发布的内容,经数据整理,选择286条微博文本纳入文本分析,用NVivo12质性分析软件辅助编码。结果:亲子冲突的表达包含了冲突诱因、冲突类型、冲突领域,和冲突管理策略等四个方面的特征。结论:研究建构了冲突诱因、冲突领域、冲突类型和冲突应对策略之间的关系模型。亲子冲突的发生是在社会文化背景下,由于家庭功能失调引发的亲子互动方式异常。亲子冲突发生以后,取积极应对策略有助于家庭功能的良性调节。 相似文献

This study explores the cognitive development of children born to adolescent mothers within South Africa compared to existing reference data, and explores development by child age bands to examine relative levels of development. Cross-sectional analyses present data from 954 adolescents (10–19 years) and their first-born children (0–68 months). All adolescents completed questionnaires relating to themselves and their children, and standardized child cognitive assessments (Mullen Scales of Early Learning) were undertaken. Cognitive development scores of the sample were lower than USA reference population scores and relative performance compared to the reference population was found to decline with increasing child age. When compared to children born to adult mothers in the sub-Saharan African region, children born to adolescent mothers (human immunodeficiency virus [HIV] unexposed; n = 724) were found to have lower cognitive development scores. Findings identify critical periods of development where intervention may be required to bolster outcomes for children born to adolescent mothers.
Highlights
- An exploration of the cognitive development of children born to adolescent mothers within South Africa utilizing the Mullen Scales of Early Learning.
- Cognitive development scores of children born to adolescent mothers within South Africa were lower compared to USA norm reference data and declined with child age.
- Previous studies utilizing the Mullen Scales of Early Learning within sub-Saharan Africa were summarized, and comparisons were made with the current sample.
- Findings highlight a potential risk of developmental delay among children born to adolescent mothers compared to children of adult mothers in the sub-Saharan African region.
