The Distressing Dream Content Inventory: Development and Initial Validation in Acute Trauma Patients

Area of Science:

• Psychology
• Neuroscience
• Clinical Research

Background:

• Distressing dreams following trauma can indicate challenges in emotional processing.
• Unsuccessful emotional processing in dreams may increase the risk of developing posttraumatic stress disorder (PTSD).
• Existing measures do not specifically assess the emotional content of dreams post-trauma.

Purpose of the Study:

• To develop and validate a clinician-rated inventory for assessing emotional dream content after trauma.
• To identify specific emotions within dreams that correlate with trauma and PTSD risk.
• To establish a tool for early identification of individuals at higher risk for PTSD.

Main Methods:

• Development of 77 items targeting seven emotions (fear, anger, sadness, seeking, care, play, lust) in dreams.
• Two independent raters scored 100 dreams using the developed items.
• Validation in Study 2 using 42 trauma patients' dreams at 1 week (T1) and 1 month (T2) post-trauma.

Main Results:

• An 18-item negative dream inventory (fear, anger, sadness) correlated with self-reported dream negativity and inversely with positivity.
• Negative dreams were linked to interpersonal violence exposure and higher acute stress at T1.
• Negative dreams at T1 prospectively predicted trauma-related nightmares and PTSD at T2.

Conclusions:

• The Distressing Dream Content Inventory is a novel, clinician-rated tool for assessing negative emotional dream content post-trauma.
• Negative dream content identified by the inventory is predictive of future PTSD risk.
• This tool aids in the early identification of individuals requiring further assessment and intervention for PTSD.
