病理性互联网使用与情绪、认知需要的模型构建

通过对1030名大学生进行问卷调查.对大学生的情绪、认知需要与网络成瘾的关系进行了探讨.结果发现:消极情绪对网络成瘾有显著而直接的正向作用.消极情绪对网络成瘾具有最强的预测力;认知需要对网络成瘾有显著而直接的负向作用;消极情绪和积极情绪均可通过认知需要间接地影响网络成瘾;男女生的情绪、认知需要对网络成瘾的影响存在差异.     

互联网使用动机、行为与其社会-心理健康的模型构建

以581名大学生为被试,采用结构方程模型技术构建了互联网使用动机、病理性互联网使用行为与其相关社会-心理健康的关系模型。其中,互联网使用动机包括信息获取性动机和人际情感性动机两种模式;病理性互联网使用行为包括上网冲动性、分离/逃避和网上优越感三个初级因素;互联网相关社会-心理健康包括孤独感、社会参与度、一般抑郁、生活幸福感和生活满意度五个初级因素,并进一步概括为社会健康和心理健康两个维度。研究结果表明,基于信息获取性动机而使用互联网有助于相关社会-心理健康水平的提高;基于人际情感性动机而使用互联网更容易导致病理性互联网使用行为,并由此对使用者的社会-心理健康产生负面影响;大学生使用互联网的积极效应大于消极效应,且信息获取性动机对社会健康具有更大的积极效应,而人际情感性动机对对心理健康具有更大的消极效应     

Sleep Deprivation and Dating Aggression Perpetration in Female College Students: The Moderating Roles of Trait Aggression,Victimization by Partner,and Alcohol Use

Dating aggression, whether it is physical or psychological, is a major social concern. The background-situational model is highly predictive of dating aggression, but it lacks consideration of biopsychosocial processes. Sleep was investigated as one such process. A sample of 108 university undergraduate women completed objective (actigraphy) and subjective measures of sleep quality as well as self-reports of dating and trait aggression. Indicators of sleep deprivation were associated with greater frequency of dating aggression perpetration. Associations were especially strong when trait aggression and victimization by the partner were higher. Contrary to hypotheses, alcohol consumption did not significantly moderate the relation between sleep and women’s aggression perpetration. Less sleep was associated with women’s more frequent aggression toward their partners, perhaps because sleep deprivation causes difficulties with emotion regulation.     

Understanding the Relationships Among Attitudes, Group Norms, and Behavior Using Behavioral Commitment: A Structural Equation Analysis of Marijuana Use

This research examines the relative importance of attitudes and group norms in determining frequency of marijuana use. In this examination, we employ a neglected concept in attitude/behavior research—behavioral commitment. We suggest that the role of attitudes and group norms will vary, in part, depending upon one's level of commitment to the behavior. Specifically, we assert that norms will increase in importance over attitudes as behavioral commitment increases. To test this hypothesis, we utilize covariance structure analysis with a nationally representative sample of high school seniors defined in terms of their commitment to marijuana use. Multiple group comparisons also are performed to assess the comparability of measurement properties and structural estimates. Results are supportive of the hypothesis. The findings are discussed in terms of previous attitude/behavior research and drug abuse prevention programs.     

Cognitive Social Maturity, Life Change Events, and Health Risk Behaviors among Adolescents: Development of a Structural Equation Model

Purpose: To examine the roles of cognitive social maturity and life change events in a structural equation model (SEM) to explain adolescents' use of marijuana, tobacco, and alcohol. Methods: Data were derived from 1322 9th and 10th graders in a HIV prevention study. Students completed a survey of their cognitive social maturity, recent life events and substance use habits. A model from a study on the metabolic control of adolescents with diabetes was modified to apply to health risk behaviors. Results: A SEM was tested and fit the data well. Lower cognitive social maturity and greater life change events significantly predicted health risk behaviors. Life events partially mediated the relationship between cognitive social maturity and health risk behaviors. Conclusions: Adolescents' social thought processes are related to their recent life events, which in turn are related to their substance use behaviors. Suggestions are made for interventions to improve adolescents' cognitive social maturity.     

Body Dissatisfaction and Eating Disorder Symptomatology: A Latent Structural Equation Modeling Analysis of Moderating Variables in 18-to-28-Year-Old Males

ABSTRACT. Although body dissatisfaction is recognized as the strongest risk factor for eating disturbances, a majority of young males are body dissatisfied, but do not concomitantly report severe levels of eating disorder symptomatology. The present investigation was designed to examine five theoretically relevant variables (i.e., body checking, emotional dysregulation, perfectionism, insecure-anxious attachment, and self-esteem) as potential moderators of the relationship between body dissatisfaction and two critical components of male eating disorder symptomatology: drive for muscularity and bulimic behaviors. Data collected from 551 Italian males between 18 and 28 years old were analyzed using latent structural equation modeling. The authors found that emotional dysregulation, body checking, insecure-anxious attachment and perfectionism intensified the relationship between body dissatisfaction and each criterion variable representing male eating disorder symptomatology; the interactions accounted respectively for an additional 2%, 7%, 4% and 5% of variance in drive for muscularity and for an additional 6%, 4%, 5%, and 2% of the variance in bulimic behaviors. By contrast self-esteem weakened this relationship and the interactions accounted for an additional 3% of the variance in both drive for muscularity and bulimic behaviors. Implications of these findings for prevention and treatment of male eating disturbances are discussed.
