title: [Family functioning, self-esteem and substance use in adolescents: a mediational model].
abstract: OBJECTIVE
  This research analyzes the direct and indirect relationships among family functioning, multidimensional self-esteem (family, academic, social, and physical self-esteem) and substance use.
  
  
  METHODS
  The study participants were composed of two independent samples of Spanish adolescents who provided information during the 2003-2004 academic year (n1 = 414, Castilla and León; n2 = 625, Comunidad Valenciana). The statistical analyses were carried out using structural equation modelling and the procedure of mediation effects analysis (Holmbeck, 1997).
  
  
  RESULTS
  Results showed a significant mediational effect of self-esteem on the relation between family functioning and adolescent substance use. Moreover, results showed, on the one hand, a protection effect of family and academic self-esteem in the face of substance use and, on the other hand, a risk effect of social and physical self-esteem.
  
  
  CONCLUSIONS
  It is necessary to adopt a multidimensional perspective when analyzing the self-esteem of adolescents with substance use and to prevent the over-valuation of social and physical dimensions.
