Female intimate partner violence perpetration: stability and predictors of mutual and nonmutual aggression across the first year of college

Cross-sectional and longitudinal predictors of mutual and nonmutual intimate partner violence (IPV) perpetration were identified in a sample of female college freshmen (N = 499). Using female reports, couples were classified as to whether the relationship included no IPV, female-only IPV, or mutual IPV (male-only IPV was too rare to analyze). Mutual IPV was more common than asymmetrical IPV, and women in mutually violent relationships perpetrated more frequent acts of physical aggression than those in female-only violent relationships. In cross-sectional analyses of IPV in the first semester of college, only partner antisocial behavior and psychological aggression distinguished female-only IPV from no IPV; witnessing mother-to-father aggression, higher psychological aggression, more frequent partner marijuana use, partner antisocial behavior, and, surprisingly, higher relationship satisfaction, discriminated mutual IPV from no IPV. Contrary to hypothesis, first semester (T1) IPV did not predict having a new partner in the second semester (T2); however, women who reported more frequent heavy episodic drinking and lower relationship satisfaction at T1 were more likely to be in a different relationship at T2. Prospective prediction of T2 IPV category failed to support the hypothesis that female-only IPV would escalate to mutual IPV. The majority of couples with female-only IPV reported no IPV at T2. After accounting for T1 IPV, the only significant predictor of T2 IPV category was T1 psychological aggression, suggesting that this may be an appropriate target for IPV prevention efforts among college dating couples.     

Components of disinhibition (vs. constraint) differentially predict aggression and alcohol use

Disinhibition (vs. Constraint; DvC), which has been shown to represent a central aspect of the externalizing domain, consists of several correlated but distinguishable underlying traits, which may have different patterns of association with various externalizing indicators. In a sample of 18‐ to 19‐year old undergraduate students (N = 430; 71.1% female), we examined the specificity and generality of the association between lower order components of DvC and both aggression and alcohol use, externalizing‐related behavioural constructs that have well‐established links to DvC. All three components of DvC—including Disagreeableness, low Self‐Control and low Accomplishment—were associated independently with Reactive Aggression, but only Disagreeableness was correlated significantly with Proactive Aggression. Also, only low Self‐Control was associated with alcohol use. Thus, aggression was broadly associated with components of DvC—although much more strongly with the Disagreeableness domain—whereas alcohol use was specifically correlated with low Self‐Control. These results suggest that lower order components of DvC have distinct patterns of associations with externalizing‐related outcomes. Copyright © 2011 John Wiley & Sons, Ltd.

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.     

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.     

Does Drinking Promote Risky Sexual Behavior?

ABSTRACT— The present review argues that, popular lore notwithstanding, the well-documented association between usual patterns of alcohol use and risky sex reflects multiple underlying processes that are both causal and noncausal (spurious) in nature. It is further argued that even alcohol's acute causal effects on sexual behavior are more variable than they are commonly assumed to be. Drinking can promote, inhibit, or have no effect on behavior, depending on the interplay of factors governing behavior in a particular situation and the content of individually held beliefs about alcohol's effects.     

假想的道德两难情境下小学儿童对说谎或说真话的抉择

研究探讨了294名7、9、11岁的小学儿童在道德两难情境下对说谎或说真话的道德行为抉择。结果表明,在个人谎故事条件下,随着年龄的增长,儿童越来越倾向于选择说真话;在集体谎故事条件下,11岁儿童比7岁、9岁儿童更倾向于选择说谎。7岁儿童已具有初步的集体观念,随着年龄的增长,小学儿童的集体观念日趋稳定。随着年龄的增长,小学儿童更多地从诚实、为集体或为个人等多个方面来陈述说谎或说真话的理由。
