Emerging adulthood is proposed as a new conception of development for the period from the late teens through the twenties, with a focus on ages 18-25. A theoretical background is presented. Then evidence is provided to support the idea that emerging adulthood is a distinct period demographically, subjectively, and in terms of identity explorations. How emerging adulthood differs from adolescence and young adulthood is explained. Finally, a cultural context for the idea of emerging adulthood is outlined, and it is specified that emerging adulthood exists only in cultures that allow young people a prolonged period of independent role exploration during the late teens and twenties.

A Theory of Development From the Late Teens Through the Twenties

The authors suggest that the most promising route to effective strategies for the prevention of adolescent alcohol and other drug problems is through a risk-focused approach. This approach requires the identification of risk factors for drug abuse, identification of methods by which risk factors have been effectively addressed, and application of these methods to appropriate high-risk and general population samples in controlled studies. The authors review risk and protective factors for drug abuse, assess a number of approaches for drug abuse prevention potential with high-risk groups, and make recommendations for research and practice.

What good is self-control? We incorporated a new measure of individual differences in self-control into two large investigations of a broad spectrum of behaviors. The new scale showed good internal consistency and retest reliability. Higher scores on self-control correlated with a higher grade point average, better adjustment (fewer reports of psychopathology, higher self-esteem), less binge eating and alcohol abuse, better relationships and interpersonal skills, secure attachment, and more optimal emotional responses. Tests for curvilinearity failed to indicate any drawbacks of so-called overcontrol, and the positive effects remained after controlling for social desirability. Low self-control is thus a significant risk factor for a broad range of personal and interpersonal problems.

We extend the routine activity perspective's situational analysis of crime to individual offending and to a broad range of deviant behaviors. In this view, unstructured socializing with peers in the absence of authority figures presents opportunities for deviance: In the presence of peers, deviant acts will be easier and more rewarding; the absence of authority figures reduces the potential for social control responses to deviance; and the lack of structure leaves time available for deviant behavior. To determine whether individuals who spend more time in unstructured socializing activities engage in deviant behaviors more frequently, we analyzed within-individual changes in routine activities and deviance across five waves of data for a national sample of more than 1,700 18- to 26-year-olds. Participation in these routine activities was strongly associated with criminal behavior, heavy alcohol use, use of marijuana and other illicit drugs, and dangerous driving. Furthermore, routine activities accounted for a substantial portion of the association between these deviant behaviors and age, sex, and socioeconomic status.

Routine Activities and Individual Deviant Behavior

Objective: This article provides information on the extent of alcohol use and other drug use among American college students. Methods: Five different sources of data are examined for estimating recent levels of alcohol (and other drug) use among college students: Harvard School of Public Health College Alcohol Study (CAS), the Core Institute (CORE), Monitoring the Future (MTF), National College Health Risk Behavior Survey (NCHRBS) and National Household Survey on Drug Abuse (NHSDA). Results: Alcohol use rates are very high among college students. Approximately two of five American college students were heavy drinkers, defined as having had five or more drinks in a row in the past 2 weeks. Alcohol use is higher among male than female students. White students are highest in heavy drinking, black students are lowest and Hispanic students are intermediate. Use of alcohol--but not cigarettes, marijuana and cocaine--is higher among college students than among noncollege age-mates. Longitudinal data show that, w...
