同伴对青少年冒险行为的影响及其作用机制

青少年更倾向于从事冒险或鲁莽行为, 并且更容易受到同伴影响。从个人特质和社交互动等多个角度探讨的研究结果表明, 同伴对青少年冒险行为存在助长作用, 即当同伴在场时, 青少年的行为会更加冒险。同伴对青少年冒险行为的作用机制可以从心理、神经、遗传、社会文化等多个层面进行解释：在心理层面, 这种影响源于青少年寻求同伴认可和归属感的需要, 以及社会学习的作用; 在神经机制层面, 源于认知控制网络和刺激处理系统的相互作用; 在遗传层面, 源于特定基因的易感性等; 在社会文化层面, 同伴影响会因文化差异而带来程度与表现上的差异。未来研究应从发展、文化心理、构建复杂模型网络等视角深入探究同伴对青少年冒险行为的影响。     

亲子关系对青少年冒险行为的影响:有调节的中介模型

为探讨亲子关系对青少年冒险行为的影响机制,采用亲子关系问卷、同伴群体特征问卷及冒险行为问卷对山东省日照市三所普通中学的1275名初一到高三学生进行调查。结果发现：（1）父母支持与亲子冲突、不良同伴交往及冒险行为均呈负相关,亲子冲突与不良同伴交往、冒险行为均呈正相关,不良同伴交往与冒险行为呈正相关;（2）父母支持显著负向预测冒险行为,亲子冲突显著正向预测冒险行为,且两者的预测作用都可以通过不良同伴交往的中介作用实现;（3）在亲子冲突影响冒险行为这一模型中,不良同伴交往起中介作用,且中介的后半路径受性别调节,具体表现为：与女生相比,男生结交不良同伴会参与更多冒险行为。结果提示,不良亲子关系和不良同伴交往都是青少年冒险行为的重要预测因素,且不良亲子关系可以通过影响同伴交往影响青少年冒险行为。此外,在这一过程中,存在性别差异,当亲子冲突较多时,尤其应当关注男孩的同伴交往情况。     

积极同伴压力、自尊对青少年不同冒险行为的影响

该研究基于问题行为理论,采用问卷法对普通高中、中职院校689名青少年学生进行调查,探讨了积极同伴压力、自尊对青少年不同冒险行为的影响及其交互作用和学校差异。结果表明:(1)中职院校生的积极同伴压力和冒险行为都显著高于普通高中生;(2)积极同伴压力不能预测青少年的适应不良冒险行为,但可显著预测普通高中生的社会可接受冒险行为;(3)自尊可显著负向预测青少年的适应不良冒险行为,显著正向预测普通高中生的社会可接受冒险行为;(4)自尊仅可以调节普通高中生的积极同伴压力与社会可接受冒险行为的关系:高自尊增强了高积极同伴压力对青少年社会可接受冒险行为的影响;但它不能调节无论哪所学校青少年的积极同伴压力与适应不良冒险行为的关系。     

亲子关系与青少年冒险行为的关系:一个有调节的中介模型

该研究探讨了亲子关系与青少年冒险行为的关系,并提出一个有调节的中介模型,考察自控力的中介效应和不良同伴交往对该效应的调节效应。对1263名青少年采用问卷调查,研究工具包括关系网络问卷、中学生自我控制能力量表、同伴群体特征问卷、青少年冒险行为问卷。结果表明：（1）自控力在亲子关系与青少年冒险行为之间起中介作用,即亲子关系通过自控力间接影响青少年的冒险行为。（2）亲子关系通过自控力的间接效应受到不良同伴交往的调节,交往较多的不良同伴使低自控力青少年的冒险行为增多。因此,自控力在亲子关系与冒险行为之间存在中介效应,且该效应受到不良同伴交往的调节。     

家庭功能与青少年消极冒险行为的关系:一个有调节的中介模型

为探讨家庭功能影响青少年消极冒险行为的作用机制及条件,采用青少年冒险行为问卷、家庭功能问卷、自尊问卷、同伴群体特征问卷对山东省日照市940名初高中学生进行调查。结果发现:(1)家庭功能不良不仅可直接预测青少年更多的消极冒险行为,而且也可通过使青少年交往更多不良同伴进而使其冒险行为进一步增多;(2)不良同伴交往对青少年消极冒险行为的预测受到个体自尊的调节。低自尊个体更容易受到不良同伴交往的影响而发生更多的消极冒险行为,表现出两风险因素的叠加效应。研究结果提示,家庭是青少年健康成长的基础,家庭功能不良可使青少年适应不良,塑造良好的同伴环境、培养良好的自我素质或可降低这一风险。     

Peer group influence as a factor in smoking behavior of adolescents

Adolescents, as the fastest growing group of smokers, have been a focus and concern of health educators and researchers. Adolescent smoking is of particular interest because initiation and early habits are known to have important implications for lifetime smoking or cessation. Despite the well-known centrality of the peer group in adolescent behavior, smoking cessation programs have been largely directed toward individuals rather than groups, with emphasis on encouraging the individual to say "no." In this paper, smoking behavior and peer group patterns among a sample of 1,689 Grade 8 students from southern Ontario were analyzed to ascertain possible patterns of indirect influence by friends and acquaintances. Gender differences also were assessed. It was found that peer groups are crucially important in the initiation of smoking among young adolescents, particularly females. The patterns of indirect peer influence on girls is such that girls are less likely to stop smoking once they have begun than are boys.     

After-School Supervision, Psychosocial Impact, and Adolescent Smoking and Alcohol Use in China

We examined effects of self-care after school hours and psychosocial factors on cigarette smoking and alcohol use among adolescents in China. Survey data were obtained from 4734 7th and 11th grade students from seven cities across China. Students were queried about the frequency and quantity of unsupervised self-care after school in an average week. Tobacco and alcohol usage were also obtained. Odds ratios were calculated to determine the strength of association between unsupervised self-care after school and substance use. Results indicated that the amount of self-care after-school (how many days and how many hours per week) was significantly associated with increased risk for smoking and alcohol use among Chinese adolescents. These associations remained significant even after controlling for anxiety, depressive symptoms, and peer influence. The interaction between unsupervised self-care after school and peer influence indicated that unsupervised self-care after school is a stronger risk factor for smoking among adolescents with pro-smoking friends. The findings suggest that substance use prevention programs for youth in China should try to enhance parental monitoring. As it may not be feasible for families to revert to a lifestyle that includes supervision by relatives, other approaches such as organized after-school care are worthy of consideration.     

Susceptibility to peer influence: using a performance-based measure to identify adolescent males at heightened risk for deviant peer socialization

A substantial amount of research has suggested that adolescents' attitudes and behaviors are influenced by peers; however, little is known regarding adolescents' individual variability, or susceptibility, to peer influence. In this study, a performance-based index from an experimental paradigm was used to directly measure adolescents' susceptibility to peers. A total of 36 adolescent boys participated in a "chat room" experiment in which they ostensibly were exposed to deviant or risky social norms communicated either by high-peer-status (i.e., popular, well-liked) or low-peer-status (i.e., unpopular, disliked) grade mates who actually were electronic confederates. Changes in adolescents' responses before and after exposure to peer norms were used as a measure of peer influence susceptibility. These same adolescents completed a questionnaire assessment at the study outset and again 18 months later to assess their actual engagement in deviant behavior and their perceptions of their best friend's engagement in deviant behavior. Only among adolescents with high levels of susceptibility to high-status peers was a significant longitudinal association revealed between their best friend's baseline deviant behavior and adolescents' own deviant behavior 18 months later. Findings support the predictive validity of a performance-based susceptibility measure and suggest that adolescents' peer influence susceptibility may generalize across peer contexts.     

Intrapersonal and Ecodevelopmental Factors Associated with Smoking in Hispanic Adolescents

We examined how relationships among intrapersonal (i.e., attitudes and beliefs about smoking) and ecodevelopmental (i.e., family, school, and peer) factors influence risk for lifetime smoking in immigrant Hispanic adolescents. Our sample was comprised of 223 immigrant Hispanic adolescents and their families and was drawn from 3 middle schools in a single school district. Data collected is a result of adolescent and parent completed questionnaires as well as county school data (i.e., GPA, teacher reported effort and conduct, absences). Results indicated only poor school functioning, peer smoking, and lack of perceived harm concerning smoking were directly related to adolescent lifetime smoking. Poor school functioning and peer smoking mediated the relationship between family functioning and adolescent smoking. Implications of these results for the design of smoking preventive interventions for immigrant Hispanic adolescents are discussed.     

同伴地位与青少年冒险行为的关系:一个有调节的中介模型

为探讨同伴地位影响青少年冒险行为的作用机制及条件,采用青少年冒险行为问卷、同伴提名问卷、自我控制能力问卷、同伴群体特征问卷对山东省日照市1288名初高中学生进行调查。结果发现,（1）同伴地位负向预测青少年冒险行为,该预测作用是通过交往不良同伴的中介作用实现的;（2）交往不良同伴对青少年冒险行为的预测受到个体自我控制能力的调节。对于高自我控制能力青少年,其冒险行为与交往不良同伴无关,但低自我控制能力青少年会因交往不良同伴而参与更多冒险行为。结果提示培养良好的自我素质,塑造良好的同伴环境对于青少年的健康发展有重要作用。     

家庭功能对青少年冒险行为的影响:自我控制能力与不良同伴交往的序列中介效应

采用问卷法对922名中学生进行调查,考察了家庭功能与青少年冒险行为的关系以及自我控制能力、不良同伴交往的中介作用。结果发现:(1)家庭功能、自我控制能力、不良同伴交往和冒险行为两两之间相关显著;(2)自我控制能力在家庭功能与青少年冒险行为之间起中介作用;(3)自我控制能力和不良同伴交往在家庭功能和青少年冒险行为之间构成序列中介,家庭功能对青少年冒险行为的影响主要通过家庭功能——自我控制能力——不良同伴交往——冒险行为这一路径实现。研究结果进一步揭示了家庭、同伴和个体自身因素影响青少年冒险行为的内在机制。     

儿童和青少年同伴侵害与攻击行为关系的三水平元分析

攻击行为在儿童和青少年的社会、情感和心理适应中发挥着重要作用, 而同伴侵害是儿童和青少年攻击行为一个重要的预测因素。先前的一些研究已经考察了儿童和青少年同伴侵害与攻击行为之间的关系, 但是尚不完全清楚调节效应对二者关系的影响。因此当前研究采用三水平元分析方法检验效应量的可靠性和一系列调节效应。在系统地搜索了2020年10月之前发表的文献后, 当前元分析确定了40项研究, 包括25605名被试, 共计333个效应量。主效应检验发现儿童和青少年的同伴侵害与攻击行为呈显著正相关。此外, 调节效应检验发现同伴侵害变量具有显著的调节作用。与身体侵害相比, 关系侵害与儿童和青少年攻击行为之间的相关更强。儿童和青少年的同伴侵害与攻击行为也受到了地区的调节, 它们之间的关系在亚洲地区比在南美洲地区更强。研究设计也是一个显著的调节变量, 儿童和青少年同伴侵害与攻击行为的相关在纵向研究中比在横向研究中更低。最后, 当前元分析的结果显示同伴侵害的报告者也是一个显著的调节变量。与同伴报告的同伴侵害相比, 教师报告的同伴侵害与儿童和青少年攻击行为之间的相关较高。当前研究的结果指出, 在预防、控制儿童和青少年的攻击行为时应该注意同伴侵害对其的影响。     

Peers influence adolescent reward processing,but not response inhibition

Most adolescent risk taking occurs in the presence of peers. Prior research suggests that peers alter adolescents’ decision making by increasing reward sensitivity and the engagement of regions involved in the processing of rewards, primarily the striatum. However, the potential influence of peers on the capacity for impulse control, and the associated recruitment of the brain’s control circuitry, has not yet been adequately examined. In the current study, adolescents underwent functional neuroimaging while they completed interleaved rounds of risk-taking and response-inhibition tasks. Social context was manipulated such that the participants believed they were either playing alone and unobserved, or watched by an anonymous peer. Compared to those who completed the tasks alone, adolescents in the peer condition took more risks during the risk-taking task and exhibited relatively heightened activation of the striatum. Activity within this striatal region also predicted individual differences in overall risk taking. In contrast, the presence of peers had no effect on behavioral response inhibition and had minimal impact on the engagement of typical cognitive control regions. In a subregion of the anterior insula engaged mutually by both tasks, activity was again found to be sensitive to social context during the risk-taking task, but not during the response-inhibition task. These findings extend the evidence that the presence of peers biases adolescents towards risk taking by increasing reward sensitivity rather than disrupting cognitive control.     

Can religious beliefs combat negative peer influence during adolescence?

The purpose of this study was to identify religiosity dimensions that might be efficacious in helping adolescents combat negative peer influence. In past studies, the protective elements of religiosity were small to non-existent once peer influence was considered. However, peer influence can take many forms and the relation between susceptibility to negative peer influence and religious beliefs is not clear. Two hundred and twenty high school students were surveyed on several dimensions of religiosity via the Attitude to Christianity Inventory, different forms of peer influence (i.e., peer conformity and perceptions of peer behaviours) and their own pro- and anti-social conduct. Through hierarchical regression analyses some religiosity dimensions (i.e., the Bible and social justice) were found to be more protective than others in predicting conduct in the context of peer conformity. Implications for intervention were addressed.     

The effects of ethnicity and acculturation on early adolescent delinquency

We examined the influence of ethnicity and acculturation status on the relationship between parental monitoring, susceptibility to antisocial peer pressure, and delinquency. The sample consisted primarily of Caucasian (63%) and Mexican-American (24%) early adolescents. Self-report data were collected from 1021 sixth and seventh graders, equally divided by gender (mean age =12.7 years). The Mexican-American adolescents were categorized into one of three acculturation groups: (a) acculturated; (b) unacculturated by choice; and (c) recent immigrants. Acculturated Mexican-American early adolescents reported significantly more delinquent behaviors than the Caucasian, unacculturated by choice, and recent immigrant youth. Recent immigrant early adolescents reported more parental monitoring than the acculturated Mexican-American early adolescents. Level of perceived susceptibility to antisocial peer pressure did not differ between ethnic or acculturation groups. Regression analyses revealed that the relationship between parental monitoring and delinquency was mediated by susceptibility to antisocial peer pressure for all the groups regardless of ethnicity or level of acculturation. Findings emphasize the importance of: (a) examining level of acculturation when sampling ethnically diverse populations; and (b) comparing global mean level differences and specific relationships among independent variables.     

越轨同伴交往与青少年问题性网络使用的交叉滞后分析

Antecedents of risk-taking behaviour among South African adolescents

This study aimed to investigate contextual predisposition to risk-taking behaviour among South African adolescents. Participants included 194 black adolescents from central South Africa (female = 50.5% between the ages of 16 and 19 years). The adolescents completed a youth risk behaviour survey as well as a questionnaire on their parental, peer, school, and community relationships. Data were analysed by means of multivariate analyses of variance and standard multiple regression analyses in order to predict risk-taking behaviour (violence, substance use, and risky sexual behaviour) from various relationship contexts (parents, peers, school, and community). Irrespective of relationship context, males portray a higher risk for all types of risky behaviour, and the more time adolescents spend with their peers, the higher their risk for engagement in risk-taking behaviour. Parental monitoring predicted a lower risk for portraying risky behaviour.     

Effects of Parenting and Deviant Peers on Early to Mid-Adolescent Conduct Problems

We investigated the influence of effective parenting behaviors (father and mother reports) and deviant peer association (adolescent reports) on subsequent young adolescent conduct problems (teacher reports) during grades 7–9, using structural equation modeling. Data were from a sample of 226 rural adolescents (n?=?112 boys; n?=?107 girls; n?=?7 gender unknown), their parents, and teachers. Both effective parenting and association with deviant peers influenced later conduct problems; however, the pattern of influence varied across time and between fathers and mothers, with complex patterns of interactions between effective parenting and peer deviance. From seventh to eighth grade, effective parenting by both mothers and fathers buffered the effect of higher levels of peer deviance on conduct problems across adolescent gender. From eighth to ninth grade (i.e., transition into high school), fathers’ effective parenting buffered the effects of deviant peer association on their daughters’ conduct problems, whereas both fathers’ and mothers’ influence was stronger for sons when deviant peer associations were lower. Analyses also evaluated bi-directional longitudinal effects among adolescents, parents, and peers. Although varying by parent and adolescent gender or adolescent age, results generally supported the protective effects of parenting on their children’s conduct problems during early to mid adolescence.     

The relation of modelling and the perception of parental care with adolescent smoking: a cross-sectional study

The smoking of tobacco among adolescents is due to several influential factors, both individual and social. The present study aimed at comparing the effects of different variables on adolescent cigarette smoking, specifically, peer and parent modelling, self-regulatory efficacy, and parental degree of care as perceived by the adolescent. Data were collected by means of a self-report questionnaire administered to a sample of 229 secondary school students aged between 15 and 20 years (mean = 16.69, SD = 1.14). To test the influence of different variables, we performed a binary logistic regression analysis. Results indicated that the father is a key figure in that his care and affection can prevent adolescents from becoming a smoker and his modelling is a risk factor. The significant influence of friends was also confirmed and indicated that peer modelling is a strong predictor of adolescent cigarette smoking. Finally, the results revealed that self-regulatory efficacy is a relevant psychological variable capable of preventing smoking initiation during adolescence.
