This trial will compare a new treatment, ABC-I, to Cognitive Behavioral Therapy for Insomnia (CBT-I) among Veterans with comorbid Post-Traumatic Stress Disorder (PTSD) and insomnia disorder. ABC-I has been shown to improve treatment adherence and the study objectives are to evaluate the benefits of ABC-I in reducing PTSD symptoms and improving insomnia symptoms and sleep quality.

Who is the study for?
Veterans over 18 living within 50 miles of the VA Sepulveda Ambulatory Care Center, who have PTSD and insomnia, and received VAGLAHS care in the past year. Excluded are those unable to consent, with unstable housing or medical conditions, pregnant or recent parents, active substance users/recently sober under 90 days, engaged in other PTSD therapies or with severe sleep disorders.Check my eligibility
What is being tested?
The trial compares ABC-I (Acceptance and Behavioral Changes to treat Insomnia) with CBT-I (Cognitive-Behavioral Therapy for Insomnia) for Veterans having both PTSD and insomnia. Each participant will receive one of these treatments through five sessions to see which is more effective at reducing PTSD symptoms and improving sleep quality.See study design
What are the potential side effects?
Since this trial involves behavioral therapy rather than medication, side effects may include discomfort from discussing personal experiences during therapy sessions but typically do not involve physical side effects like those associated with drugs.

Other Research
Common treatments for insomnia, such as Cognitive Behavioral Therapy for Insomnia (CBT-I) and Acceptance and Commitment Therapy (ACT), work by addressing both behavioral and emotional components of the disorder. CBT-I focuses on changing sleep-related behaviors and thoughts through techniques like sleep restriction, stimulus control, and cognitive restructuring. ACT helps patients accept insomnia-related thoughts and feelings without letting them dictate behavior, emphasizing actions aligned with personal values. This dual approach can improve treatment adherence and outcomes by providing comprehensive management of insomnia symptoms.
Testing two types of self-help CBT-I for insomnia in older adults with arthritis or coronary artery disease.
