Participants will be randomized to one of two conditions: Early Withdrawal Exposure + Withdrawal Relaxation Training (E+WT) or Relaxation Training (RT) control. The E+WT condition will consist of the development, application, modification, and repeated practice of individualized withdrawal regulation for behavioral and cognitive strategies. the RT condition will control for the therapeutic contact received by those in the E+WT condition and will consist of the development, application, modification, and repeated practice of individualized relaxation techniques (e.g. breathing exercises, imagery).
