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。     

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。     

青少年早期攻击和违纪行为的关系：受欢迎度的调节作用

以1755名初中一年级青少年为被试考察青少年早期个体攻击和违纪行为之间的关系,并对受欢迎度的调节作用进行了检验。结果表明,（1）在青少年早期,身体攻击能正向预测违纪行为,而关系攻击不能。（2）个体的受欢迎度能够调节身体攻击与违纪行为间的关系,具体表现为身体攻击对不受欢迎个体违纪行为的影响比对受欢迎个体的影响更大。     

Social norms in adolescent risk engagement and recommendation

Social influence is an important determinant of adolescent risk-taking, but little is known about how social norms contribute to adolescents’ tendency to recommend and engage in risky behaviours. Using the Adolescent Risk-taking Questionnaire, we assessed subjects’ (n = 198, age = 10–26) propensity to engage in and recommend risk-taking as well as their perception of risk norms. Adolescents recommended risk-taking more often compared to children and young adults. Perceived social norms were the most important factor predicting engagement in risky behaviours, and adolescents perceived risk-taking to be more normative than children or adults. Our findings highlight two mechanisms that contribute to adolescent risk-taking, active recommendation and perceived social norms. On this basis, we discuss potential means to attenuate excessive adolescent risk-taking.     

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。     

Local erotic songs and chants among rural Nigerian adolescent males

This paper investigates local erotic songs and chants circulating among adolescent males in Nigeria. The purpose is to assess the critical themes which these erotic verses evoke and their potentials in the discursive construction of adolescent sexual identities and definition of the (erotic) spaces and meanings on the basis of which young Nigerian males constitute their sexual conducts. Data indicate high level of awareness and knowledge of local erotic songs and chants among adolescent males. The songs and chants were reportedly used to learn about gender and sex roles, the body, and sexuality, and for recreation. Themes in local boys’ erotic songs and chants are primarily male privileging and penis advantaging, and celebrate male sexual activity, desire, violence, ruthlessness, and risk-taking as well as male control and subordination of women and their body. The songs and chants depict feminity and female sexuality as inferior to masculinity and male sexuality and tend to objectify women’s body as a facility for male sexual pleasure. The paper argues that while erotic verses circulating among adolescent Nigerian males help relieve them of the difficulties caused by the cultural relegation of sex and sexuality to the realm of the unspoken, they contain very disturbing and potentially dangerous images that provide little space for male responsibility and respect for women. Local erotic verses circulating among adolescents present an under-explored resource in sexuality education and a critical entry point for current efforts to understand and help young people extricate themselves from the sea of half-truths, myths, and prejudices about sex and sexuality.     

Developmental changes in dopamine neurotransmission in adolescence: Behavioral implications and issues in assessment

Adolescence is characterized by increased risk-taking, novelty-seeking, and locomotor activity, all of which suggest a heightened appetitive drive. The neurotransmitter dopamine is typically associated with behavioral activation and heightened forms of appetitive behavior in mammalian species, and this pattern of activation has been described in terms of a neurobehavioral system that underlies incentive-motivated behavior. Adolescence may be a time of elevated activity within this system. This review provides a summary of changes within cortical and subcortical dopaminergic systems that may account for changes in cognition and affect that characterize adolescent behavior. Because there is a dearth of information regarding neurochemical changes in human adolescents, models for assessing links between neurochemical activity and behavior in human adolescents will be described using molecular genetic techniques. Furthermore, we will suggest how these techniques can be combined with other methods such as pharmacology to measure the impact of dopamine activity on behavior and how this relation changes through the lifespan.     

Effects of Father-Adolescent and Mother-Adolescent Relationships on Depressive Symptoms among Chinese Early Adolescents

Parent–adolescent relationships play an important role in protecting adolescents from depressive symptoms. However, there are no consistent conclusions about the extent to which fathers and mothers uniquely contribute to adolescents’ depressive symptoms. The present study aimed to acquire knowledge in this research area in two ways. First, this study separated the potential impacts of father–child and mother–child relationships on depressive symptoms in Chinese adolescents. Second, this study used a longitudinal design with nationally representative samples from the China Education Panel Survey. A total of 8794 middle school students in grade 7 completed measures of father–adolescent and mother–adolescent relationships, and depressive symptoms twice (T1 and T2; one-year interval). Results indicated that both positive father–adolescent and mother–adolescent relationships had negative effects on depressive symptoms in female adolescents. However, positive father-adolescent, not mother-adolescent, relationships had a negative effect on depressive symptoms in male adolescents. These findings suggest that positive parent–adolescent relationships could reduce early adolescents’ depressive symptoms, but positive father–adolescent and mother–adolescent relationships might have different protective effects on early adolescents’ depressive symptoms among male and female adolescents in China.

     

Risk taking as a predictor of adolescent sexual activity and use of contraception

A hypothesis of high-risk behaviors associated with adolescent sexual activity and lack of contraceptive use was tested in a longitudinal random sample of both male and female youths. The data were part of the Rutgers Health and Human Development Project. 1380 subjects were ascertained by random telephone calling were given self-report questionnaires and personality profiles including the Zuckerman's Sensation Seeking Scale, and Jackson's Personality Research Form in 1979 and 1981. Incidence of sexual activity and use of contraceptives increased with age from age 12-21. Cohort effects were apparent with use of some contraceptive methods. Of the variables indicating risk- taking, disinhibition, impulsivity and experience seeking, there were significant associations between sexual activity and disinhibition and experience seeking, for females. There were no significant associations between these variables and sexual activity in males. Contrary to the hypothesis, there were no relationships between either consistency of birth control use or reliability of the method used and behavioral indicators of risk-taking. Thus this 1st study in the field that included both males and females from the general population, as opposed to college students, found that sexually active adolescents were higher risk-takers than virgins, but no relationship between risk-taking and effectiveness of contraception was observed.     

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。     

Romantic involvement and depressive symptoms in early and late adolescence: The role of a preoccupied relational style

Two studies examined the association between depressive symptoms and romantic involvement in adolescence and tested the hypothesis that romantic involvement is associated more strongly with symptoms among adolescents who have a more preoccupied style of relating, compared to adolescents who have a less preoccupied style of relating. Study 1 (N = 96 early adolescent females) examined concurrent associations and Study 2 (N = 80 late adolescent males and females) examined longitudinal associations. In both age groups, romantic involvement was associated with greater depressive symptoms and this was most true among adolescents with a preoccupied style of relating. Implications for models of depression and adolescent romantic functioning are discussed.     

The drug‐crime nexus among adolescents and their peers

The purpose of this paper is to determine the nature of the drug‐crime relationship by exploring the influence of friend behaviors on both adolescent delinquent and substance using behavior. The sample consists of 1381 adolescents evenly divided by gender into three age groups (12, 15 and 18 years old). In general, there is an increase in intensity of substance use from the youngest to the oldest age level with male and female levels being similar within each age group. There are both age and gender differences when examining delinquent behavior. There is a relationship between adolescent drug use and crime (especially among males), however this relationship is relatively modest. In addition, while friends’ behavior is a very strong predictor of the same type of behavior in subjects, there are no strong crossover relationships. Thus, the hypothesis that both types of behavior are part of a specific deviant peer subculture is not confirmed.     

A cross-sectional and longitudinal analysis of reward-related brain activation: Effects of age,pubertal stage,and reward sensitivity

Neurobiological models suggest that adolescents are driven by an overactive ventral striatum (VS) response to rewards that may lead to an adolescent increase in risk-taking behavior. However, empirical studies showed mixed findings of adolescents’ brain response to rewards. In this study, we aimed to elucidate the relationship between reward-related brain activation and risky decision-making. In addition, we examined effects of age, puberty, and individuals’ reward sensitivity. We collected two datasets: Experiment 1 reports cross-sectional brain data from 75 participants (ages 10–25) who played a risky decision task. Experiment 2 presents a longitudinal extension in which a subset of these adolescents (n = 33) was measured again 2 years later. Results showed that (1) a reward-related network including VS and medial PFC was consistently activated over time, (2) the propensity to choose the risky option was related to increased reward-related activation in VS and medial PFC, and (3) longitudinal comparisons indicated that self-reported reward sensitivity was specifically related to VS activation over time. Together, these results advance our insights in the brain circuitry underlying reward processing across adolescence.     

Parent-adolescent intimacy: impact on adolescent functioning

This paper examines the influence of parent-adolescent intimacy on adolescent functioning. Intimacy for both adolescent males and females was assessed in relation to their mothers and fathers. Adolescent development was measured using two scales: self-esteem and problem behavior. No significant differences were found between males and females on the measures of self-esteem, problem behavior, and intimacy. However, mothers were found to share greater degrees of intimacy than did fathers for both male and female adolescents. A regression analysis revealed that father intimacy was a better predictor of positive adolescent functioning than was mother intimacy.     

Direct and interactive effects of parent,friend and schoolmate drinking on alcohol use trajectories

Objective: This study considered the unique and interactive roles of social norms from parents, friends and schools in predicting developmental trajectories of adolescent drinking and intoxication.

Design and outcome measures: Using data from the National Longitudinal Study of Adolescent Health, which followed adolescents (N = 18,921) for 13 years, we used discrete mixture modelling to identify unique developmental trajectories of drinking and of intoxication. Next, multilevel multinomial regression models examined the role of alcohol-related social norms from parents, friends and schoolmates in the prediction of youths’ trajectory group membership.

Results: Results demonstrated that social norms from parents, friends and schoolmates that were favourable towards alcohol use uniquely predicted drinking and intoxication trajectory group membership. Interactions between social norms revealed that schoolmate drinking played an important moderating role, frequently augmenting social norms from parents and friends. The current findings suggest that social norms from multiple sources (parents, friends and schools) work both independently and interactively to predict longitudinal trajectories of adolescent alcohol use.

Conclusions: Results highlight the need to identify and understand social messages from multiple developmental contexts in efforts to reduce adolescent alcohol consumption and alcohol-related risk-taking.     

Operating within the mainstream: Coping and adjustment among a sample of homosexual youths

A sample (N = 37) of African American adolescent homosexual males was administered a questionnaire that focused on four areas of social psychological functioning (self‐identity, family relation, school‐work relations, and social adjustment). The findings contradicted several past studies that reported in general that homosexual males experience crippling cognitive dissonance. Even with the existence of homophobia in the society, the adolescents were found to possess an adequate social psychological attitude and survival skills. The sampled adolescents reported being comfortable with their sexual orientation even though the majority of them had not disclosed their homosexuality. The respondents reported how they managed self‐presentation among heterosexual persons. The adolescents appeared well‐adjusted and stable in their social functioning and disagreed with the idea that they needed professional counseling.     

Discrepancies Between Parent and Adolescent Beliefs About Daily Life Topics and Performance on an Emotion Recognition Task

Parents and children and adolescents commonly disagree in their perceptions of a variety of behaviors, including the family relationship and environment, and child and adolescent psychopathology. To this end, numerous studies have examined to what extent increased discrepant perceptions—particularly with regard to perceptions of the family relationship and environment—predict increased child and adolescent psychopathology. Parents’ and children and adolescents’ abilities to decode and identify others’ emotions (i.e., emotion recognition) may play a role in the link between discrepant perceptions and child and adolescent psychopathology. We examined parents’ and adolescents’ emotion recognition abilities in relation to discrepancies between parent and adolescent perceptions of daily life topics. In a sample of 50 parents and adolescents ages 14-to-17 years (M?=?15.4 years, 20 males, 54 % African-American), parents and adolescents were each administered a widely used performance-based measure of emotion recognition. Parents and adolescents were also administered a structured interview designed to directly assess each of their perceptions of the extent to which discrepancies existed in their beliefs about daily life topics (e.g., whether adolescents should complete their homework and carry out household chores). Interestingly, lower parent and adolescent emotion recognition performance significantly related to greater parent and adolescent perceived discrepant beliefs about daily life topics. We observed this relation whilst accounting for adolescent age and gender and levels of parent-adolescent conflict. These findings have important implications for understanding and using informant discrepancies in both basic developmental psychopathology research and applied research in clinic settings (e.g., discrepant views on therapeutic goals).     

Dominance-popularity status, behavior, and the emergence of sexual activity in young adolescents

In this paper, we investigated the sexual activity levels of several subtypes of middle adolescents (age 14-15 years). The subtype profiles were based on dominance-popularity status and a range of behaviors associated with dominance and popularity. In addition, gender differences in behavioral profiles were examined among dominant-popular, sexually active young adolescents. Results showed that socially dominant and popular young adolescent boys who exhibited a highly aggressive profile were more sexually active than their low-status and non-aggressive male peers; dominant-popular girls who were very attractive and gossips were more sexually active than their female peers. The results are discussed from an evolutionary psychological framework.     

亲子关系与青少年心理资本的关系:友谊质量的中介效应与学校联结的调节效应

该研究探讨了亲子关系与青少年心理资本的关系,并提出一个有调节的中介模型,考察友谊质量的中介效应和学校联结对该效应的调节效应。研究采用问卷调查的方式,对732名青少年进行了研究,研究工具包括亲子关系量表、心理资本量表、友谊质量量表、学校联结量表。结果表明：（1）友谊质量在亲子关系与青少年心理资本之间起中介作用,即亲子关系通过友谊质量间接影响青少年的心理资本。（2）亲子关系通过友谊质量对青少年的心理资本的间接效应受学校联结的调节,且这种间接效应在低学校联结的青少年中更显著。本研究验证了家庭系统、同伴系统和学校系统对个人系统（心理资本）的联合作用,对青少年心理资本的提高有一定的指导意义。     

Relation of parental support and control to adolescents' externalizing symptomatology and substance use: A longitudinal examination of curvilinear effects

Past research has generated inconsistent findings regarding the relation of parental control and support to adolescent problem behaviors. Using two waves of data collected 1 year apart, the current study examined the influence of parental control and support on adolescents' externalizing symptoms, alcohol use, and illicit substance use. A sample of adolescents and their parents (@#@ N =454) was studied, within which approximately half of the adolescents were at high risk because of parental alcoholism. Multipleregression analyses of crosssectional data showed a negative quadratic relation between parental control and adolescent externalizing symptomatology, and between parental control and adolescent illicit substance use. Parental control had a negative linear relation to adolescent alcohol use. Parental support showed a negative quadratic relation to adolescent illicit substance use, and negative linear relations to adolescent alcohol use and externalizing symptoms. Although longitudinally adjusted contemporaneous results were consistent with crosssectional findings, parental support and control were prospectively related only to adolescent alcohol use. The quadratic relations suggest that adolescents who receive either extreme of parental support or control are at risk for problem behaviors.
