title: [Using the partial least squares approach for comprehending the motivational factors in the activity of consuming psychoactive products in adolescents].
abstract: Practice of a sport is associated with better health but it can also be linked to behavioral disorders of adolescents. It is therefore necessary to identify what influences these health problems.
  
  
  OBJECTIVE
  We evaluated the effect of sports motivation and achievement goals on the substances use of adolescents using the PLS approach. A proposal for modelling with latent variables creating motivational and consumption of substances has been conducted among adolescents over a period of 20 months.
  
  
  METHODS
  This research was conducted among 105 adolescents aged an average of 17 years.
  
  
  RESULTS
  The analysis of data in PLS has revealed the essential role of sport motivation and achievement goals in the behavioral disorders in adolescence. We also made a comparison of PLS with a statistical regression classic.
