Mental health among children and adolescents: Construct validity, reliability, and parent-adolescent agreement on the 'Strengths and Difficulties Questionnaire' in Chile.

The Strengths and Difficulties Questionnaire (SDQ) is a screening tool used to measure psychological functioning among children and adolescents.

This is the first study exploring the construct validity and reliability of the Spanish version of SDQ among early adolescents (self-reported) and their parents in Latin America.

[Smoking and alcohol use among Chilean teenagers aged 10 to 14 years].

Background: Smoking and alcohol use are risky behaviors that can start early in life.

Aim: To determine the lifetime prevalence of tobacco and alcohol use in adolescents aged 10 to 14 years and related factors.

Subjects And Methods: A survey about smoking and alcohol use was answered by 1,392 teenagers aged 10 to 14 years (46% women) from seven schools in a small city near Santiago.

Brief report: Association between psychological sense of school membership and mental health among early adolescents.

Mental health problems among adolescents are prevalent and are associated with important difficulties for a normal development during this period and later in life. Understanding better the risk factors associated with mental health problems may help to design and implement more effective preventive interventions. Several personal and family risk factors have been identified in their relationship to mental health; however, much less is known about the influence of school-related factors.
