Experimentation versus progression in adolescent drug use: A test of an emerging neurobehavioral imbalance model / Atika KHURANA in Development and Psychopathology, 27-3 (August 2015)
[article]
Titre : Experimentation versus progression in adolescent drug use: A test of an emerging neurobehavioral imbalance model Type de document : Texte imprimé et/ou numérique Auteurs : Atika KHURANA, Auteur ; Daniel ROMER, Auteur ; Laura M. BETANCOURT, Auteur ; Nancy L. BRODSKY, Auteur ; Joan M. GIANNETTA, Auteur ; Hallam HURT, Auteur Article en page(s) : p.901-913 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Based on an emerging neuroscience model of addiction, this study examines how an imbalance between two neurobehavioral systems (reward motivation and executive control) can distinguish between early adolescent progressive drug use and mere experimentation with drugs. Data from four annual assessments of a community cohort (N = 382) of 11- to 13-year-olds were analyzed to model heterogeneity in patterns of early drug use. Baseline assessments of working memory (an indicator of the functional integrity of the executive control system) and three dimensions of impulsivity (characterizing the balance between reward seeking and executive control systems) were used to predict heterogeneous latent classes of drug use trajectories from early to midadolescence. Findings revealed that an imbalance resulting from weak executive control and heightened reward seeking was predictive of early progression in drug use, while heightened reward seeking balanced by a strong control system was predictive of occasional experimentation only. Implications of these results are discussed in terms of preventive interventions that can target underlying weaknesses in executive control during younger years, and potentially enable at-risk adolescents to exercise greater self-restraint in the context of rewarding drug-related cues.

Titre : Where do youth learn about suicides on the Internet, and what influence does this have on suicidal ideation? Type de document : Texte imprimé et/ou numérique Auteurs : Sally M. DUNLOP, Auteur ; Eian MORE, Auteur ; Daniel ROMER, Auteur Année de publication : 2011 Article en page(s) : p.1073-1080 Langues : Anglais (eng) Mots-clés : Internet sites suicidal ideation adolescents;social networking online discussion forums online news hopelessness Index. décimale : PER Périodiques Résumé : Background: Young people are susceptible to suicidal behavior as a result of learning about the suicidal behavior of others. This study was designed to determine whether Internet sites, such as online news and social networking websites, expose young people to suicide stories that might increase suicide ideation.
Method: We reinterviewed 719 young people ages 14 to 24 who had participated in a prior nationally representative survey. Respondents reported knowledge of persons they knew who had committed or attempted suicide as well as personal experiences of hopelessness and suicidal ideation on both occasions. On the second occasion one year later, they also reported use of various Internet platforms and how often they had been exposed to suicide stories on those sites, as well as from personal sources. Changes in ideation as a function of exposure to different sources of suicide stories were analyzed holding constant prior hopelessness and ideation.
Results: While traditional sources of information about suicide were most often cited (79% were from friends and family or newspapers), online sources were also quite common (59%). Social networking sites were frequently cited as sources, but these reports were not linked to increases in ideation. However, online discussion forums were both cited as sources and associated with increases in ideation.
Conclusions: The Internet and especially social networking sites are important sources of suicide stories. However, discussion forums appear to be particularly associated with increases in suicidal ideation. Greater efforts should be undertaken to promote Internet sites directed to young people that enhance effective coping with hopelessness and suicidal ideation.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2011.02416.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=142
