Substance abuse continues to be a growing concern in America with more efforts to improve the overall quality of treatment for Substance Use Disorders (SUDs). A history of trauma experiences significantly increased the likelihood of an individual turning to substances to cope. However, psychological abuse remains understudied with its relation to substance use behaviors. This study will explore independently licensed counselors' experiences, perspectives, and processes when working with clients with substance use disorders who have experienced psychological abuse. A transcendental phenomenological tradition was used by the researcher and research team members to analyze the experiences of the participants (N = 12). The following themes were found within those experiences: a) "Comprehending Contributing Factors to Clients' Addiction," b) "Acknowledging Challenges to Proper Treatment," c) "Implementing Clinical Interventions for Successful Treatment," and d) "Observing Signs of Client Growth." Study limitations and implications for counseling, supervision and counselor education are provided. [The dissertation citations contained here are published with the permission of ProQuest LLC.
