Dissociation, PTSD, and substance abuse: an empirical study

Area of Science:

• Psychology
• Psychiatry
• Neuroscience

Background:

• Posttraumatic stress disorder (PTSD), substance use disorder (SUD), and dissociation are frequently comorbid.
• Few studies have explored the interplay between these conditions, particularly in women.

Purpose of the Study:

• To investigate the relationship between PTSD, SUD, and dissociation in women.
• To compare the clinical profiles of women with PTSD and SUD based on dissociation levels.

Main Methods:

• Seventy-seven women with current PTSD and substance dependence were assessed.
• Participants were categorized into high- and low-dissociation groups using the Dissociative Experiences Scale.
• Comparisons were made on trauma-related symptoms, substance use, cognitions, coping skills, social adjustment, trauma history, psychiatric symptoms, and self-harm/suicidal behaviors.

Main Results:

• The high-dissociation group exhibited significantly greater impairment across multiple domains compared to the low-dissociation group.
• High levels of dissociation were prevalent in the sample, irrespective of recent substance use.
• Individuals in the high-dissociation group reported a stronger belief in substances' ability to manage psychiatric symptoms.
• The high-dissociation group reported more trauma-related symptoms and a history of childhood emotional abuse and physical neglect.

Conclusions:

• Dissociation is a critical factor influencing the severity of symptoms and impairment in women with comorbid PTSD and SUD.
• The findings support the need for integrated treatment approaches addressing both trauma and dissociation in individuals with substance use disorders.
• Further research is warranted to understand the "chemical dissociation" hypothesis and the nuanced experience of substances in relation to dissociative phenomena.
