Enhanced Consent for Symptom Provocation Research

Not Applicable
Terminated
Conditions
Trauma
Interventions
Behavioral: Enhanced consent procedure
Behavioral: Consent as Usual
Registration Number
NCT01809899
Lead Sponsor
Georgetown University
Brief Summary

The overall goal of the proposed study is to insure the protection and safety of human subjects who have been previously exposed to interpersonal traumatic events and who are participants in symptom provocation research. The investigators intend to examine trauma history, cognitive, interpersonal, and genetic predictors of participants' unfavorable reaction to participation in research involving trauma-related script-driven imagery (SDI). The design includes comparing participants in a consent as usual group to participants in an enhanced consent group to see which minimizes unfavorable effects of participating in a research provocation study. In addition, the two different consent groups will be assessed for their effects on psychobiological and neurobiological stress response. Furthermore, the investigators will examine the relationship between the psychobiological responses and neural mechanism during SDI, and unfavorable reactions to participation in symptom provocation research.

Detailed Description

The overall goal of the proposed study is to insure the protection and safety of human subjects who have been previously exposed to interpersonal traumatic events and who are participants in symptom provocation research. The investigators intend to examine trauma history, cognitive, interpersonal, and genetic predictors of participants' unfavorable reaction to participation in research involving trauma-related script-driven imagery (SDI). The design includes comparing participants with and without Posttraumatic Stress Disorder (PTSD) in a consent as usual group to participants in an enhanced consent group to see which group minimizes unfavorable effects of participating in a research provocation study. In addition, the two different consent groups will be assessed for their effects on psychobiological and neurobiological stress response. Furthermore, the investigators will examine the relationship between the psychobiological responses and neural mechanism during SDI, and unfavorable reactions to participation in symptom provocation research.

Primary Outcome Measures
NameTimeMethod
Blood Oxygen-Level Dependent (BOLD) SignalBaseline

Functional Magnetic Resonance Imaging (fMRI). We were examining differences in Blood Oxygen-Level Dependent (BOLD) signal indicating reaction to a stress-provocation paradigm between the Enhanced Consent and Consent as Usual conditions.

Secondary Outcome Measures
NameTimeMethod
Heart RateBaseline

Heart rate was measured while in the scanner as a secondary psychobiological outcome to be considered in tandem with the BOLD signals from the scanner.
