Clinical Trial Summary

The purpose of this randomized control trial is to examine the effects of a Mindfulness-Based Stress Reduction (MBSR) program on women with posttraumatic stress disorder related to intimate partner violence.

Description:

Posttraumatic stress disorder is a prevalent, chronic, and debilitating disorder characterized by a reduced capacity to adapt to stressors, marked by poor regulation in the following domains: emotion, attentional function, and physiological stress. Mindfulness-based stress reduction (MBSR) holds promise for treating symptoms of trauma and PTSD as evidence suggests it targets these domains. The central hypothesis is that MBSR, which teaches non-judgmental awareness, can improve emotion regulation and attentional function, and diminish physiological stress dysregulation, which in turn will improve PTSD symptoms. We will examine changes in stress capacity and PTSD symptom severity among women survivors of intimate partner violence with PTSD after participation in an MBSR program.

Eligibility

Inclusion Criteria:

• English-speaking

• Women

• 18-64 years of age

• Victim of IPV

• Meet diagnostic criteria for PTSD

• No or stable use of medications (including, for example, beta blockers).

Exclusion Criteria:

• There is suspicion or evidence of dementia or cognitive impairment (Mini-Mental State Examination score < 24) or inability to provide informed consent

• They have ever been a perpetrator of IPV

• History of schizophrenia or bipolar I disorder; current suicidality with either plan, intent, or a suicide attempt in the past 6 months

• Active substance dependence or in remission < 3 months

• Cardiovascular conditions (e.g., congestive heart failure, pacemaker, prior myocardial infarction)

• The age range was chosen to reduce heterogeneity in this pilot study, as aging is associated with changes in emotion regulation, attention, and PNS tone.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	PTSD Symptoms Checklist (PCL-5)	The PTSD Symptoms Checklist (PCL-5) is a 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD. The PCL-5 asks respondents to rate how much they have been bothered by particular PTSD symptoms in the past month on a 0-4 scale.	12 weeks
Secondary	Difficulties in Emotion Regulation Scale (DERS)	The Difficulties in Emotion Regulation Scale (DERS) is a 36-item self-report measure that assesses emotion dysregulation in six domains: nonacceptance of emotional responses, difficulties engaging in goal directed behavior, impulse control difficulties, lack of emotional awareness, limited access to emotion regulation strategies, and lack of emotional clarity.	12 weeks
Secondary	Heart rate variability	To assess cardiovascular measures, ECG, basal thoracic impedance (Z0), the first derivative of the impedance signal (dZ/dt), and continuous strain gauge signal, will be obtained (BioNex Mainframe, Mindware Technologies, Gahanna, OH). Three disposable ECG electrodes will be placed in a lead II configuration to record the ECG signal. Four additional disposable patient ECG spot electrodes (2 current and 2 recording electrodes) will be used to obtain the Z0 and dZ/dt signals. A strain gauge will be secured around the lower chest to record respiration rate. The BioNex will be connected to a laptop: signals will be conditioned and collected (1000 Hz sampling; 5 Hz for strain gauge) through an integrated A/D board, and written to disk and later scored (with Mindware software).	12 weeks
Secondary	Useful Field of View Test (UFOV)	The Useful Field of View Test (UFOV) is a computerized test with 3 assessments: speed of processing; selective attention; divided attention. The test determines the minimum display duration at which participants can process information for increasingly difficult subtests and is the primary outcome for prior studies of speed of processing training.	12 weeks
Secondary	Five-Facet Mindfulness Questionnaire (FFMQ)	The Five-Facet Mindfulness Questionnaire assesses five factors that represent mindfulness as it is currently conceptualized: observing, describing, acting with awareness, non-judging of inner experience, and non-reactivity to inner experience.	12 weeks
