This study aims to compare the efficacy of the third wave of psychological treatments in addressing impulsivity among women with substance-related and addictive disorders.<br> <b>Methods</b>: This study adopts an experimental design with both experimental and control groups. The target population consists of women exhibiting impulsivity and substance-related and addictive disorders in Zahedan city, Iran.
