Association between adolescent rough-and-tumble play and conduct problems, substance use, and risk-taking behaviors: Findings from a school-based sample.

Rough-and-tumble play (RTP), also known as play fighting, is a common form of play frequently reported and studied by researchers. However, one important limitation of past research in the area of RTP has been the neglect of the adolescence period. Consequently, little is known about the function of adolescent RTP as well as about clinical characteristics of youth who engage in this activity after childhood.

Adolescent Mental Health and the Choking Game.

Objectives: To examine the demographic and health risk factors associated with participation in the choking game (CG), a dangerous and potentially fatal strangulation activity in which pressure is applied to the carotid artery to temporarily limit blood flow and oxygen.

Methods: We obtained data from 2 cross-sectional studies realized respectively in 2009 and 2013 among French middle school students. The 2009 ( = 746) and 2013 ( = 1025) data sets were merged ( = 1771), and multivariate modeling was conducted to examine demographic and clinical characteristics of youth reporting a lifetime participation in the CG.

Psychotropic drug use among the elderly: risk factors involved in long-term use.

This study explores the environmental, clinical, and personality factors that are associated with increased chronic psychotropic drug consumption in elderly patients. We collected data from 88 elderly individuals living in nursing homes, home-dwellings, and residential homes between December 2003 and June 2004. We assessed each subject's (1) current (previous four weeks) and chronic (>90 days) psychotropic drug consumption, (2) mood and anxiety (GHQ), and (3) personality (Temperament and Character Inventory).

Temperament and character dimensions associated with clinical characteristics and treatment outcome in attention-deficit/hyperactivity disorder boys.

Background: Although differential patterns of temperament and character have been documented in subjects with attention-deficit/hyperactivity disorder (ADHD), few studies have investigated relations between these dimensions, clinical features of ADHD, and treatment outcome.

Methods: Ninety-five boys with ADHD and 87 controls participated in the study; 88.5% of the referred patients were reassessed after optimal titration of methylphendiate treatment.

Psychometric properties of a French version of the junior temperament and character inventory.

The junior temperament and character inventory (JTCI) has been developed for the assessment of temperament and character dimensions in childhood based on Cloninger's model of personality. We evaluated the psychometric proprieties of a French child and parent-rated version of the JTCI based on a previous German version, and assessed the correlations between the JTCI dimension scores and the scores on the child behavior checklist (CBCL) in a community sample of French children and adolescents aged 10-16 years. We used data from 452 child-rated and 233 -parent-rated JCTI.
