As the findings revealed, the values of &beta; and t indicated that the motivation for excitement (&beta;=0.346; t= 3.317; p=0.001) and for irresponsibility (&beta;=0.202; t=1.975, p=0.05) played the most pivotal role in predicting the tendency to use narcotics, respectively. In addition, the values of &beta; and t also demonstrated that motivation to seek excitement (&beta;=0.351; t=3.412; p=0.001) played the most important role in predicting teenage girls&#39; tendency to drink. Finally, irresponsibility (&beta;=0.207; t=1.972; p=0.05) and accounting (&beta;=-0.191; t=-2.094; p=0.038) had the most important role in the prediction of smoking tendency variable, respectively.<br> <span style="color:#009999;"><strong><em>Conclusions:</em></strong> </span>The findings showed that the emotional and unhealthy motivations had the most pivotal role in predicting female adolescents&#39; tendency to use drugs.
