NCT02945371

Brief Summary

Insufficient inhibitory control is one pathway through which early adversity is related to a range of problems including excessive alcohol use, tobacco use, and unhealthy eating. The proposed research leverages a neurally informed model of inhibitory control and how it can be improved to test the efficacy of a person-centered inhibitory control intervention in a sample of mid-life individuals with early adversity. The knowledge obtained by this study could be scaled into a flexible, low-cost, and wide-ranging intervention to remediate some of the effects of early adversity on inhibitory control and thus a number of prevalent health risking behaviors.

Study Arms (2)

IC Training

EXPERIMENTAL

The experimental arm (ARM1) is a "person-centered inhibitory control" training intervention, or PeCIC. Between the baseline and endpoint sessions, participants come to our lab 12 times to participate in the training sessions. Each participant is randomly assigned to either the PeCIC training or an active control training. The training sessions will take place approx. every other day for 24 days. Beginning 2-3 days after the baseline session, the experimental group (will come to our behavioral testing lab to receive the PeCIC training. At 11 sessions spaced one every other day, participants will complete one 8-min run of a modified stop-signal task. The cue on each trial (preceding the "go" signal arrow) will be an image of a personalized risk-cue (PRC) or a neural image.

Behavioral: Person-centered inhibitory control training

Control Training

ACTIVE COMPARATOR

Participants in the active control group (ARM2) of the PeCIC intervention will come to the behavioral testing laboratory to complete an 8-min control task every other day for 12 sessions. This control task is identical to the PeCIC except the auditory stop cues are omitted. All other procedures, settings, and schedules are identical to those in the experimental group. The only difference between the groups is that the active control does not practice IC.

Behavioral: Active behavioral response training

Interventions

A brief, computer-based, multisession training aimed at increasing the connection between environmental risk cues (e.g., cigarettes) and engagement of the brain network for inhibitory control.

Also known as: PeCIC, ARM1
IC Training

A brief computer-based, multisession training aimed at training behavioral responses to personalized environmental risk cues (e.g., cigarettes) that does not engage the inhibitory control network of the brain.

Also known as: Active control, ARM2

Eligibility Criteria

Age35 Years - 55 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Age 35-55
  • Experience of early adversity (EA) before age 18 (EA is be defined as a score of 4 or higher on the Adverse Childhood Experiences (ACEs) questionnaire \[Felitti, Anda, Nordenberg, Williamson, Spitz, Edwards, et al., 1998\])
  • IC difficulties such as disinhibited alcohol use, tobacco use, or food intake during adulthood. IC difficulties will be self-reported based on questions from the self-control questionnaire (Tangney, Baumeister, \& Boone, 2004) modified to be specific to alcohol, tobacco, and energy-dense food intake (e.g., "I am self-indulgent with unhealthy food at times", "I refuse alcohol when offered") using a 4-point Likert-style scale.

You may not qualify if:

  • Individuals over age 55 will be excluded because of established functional and structural neural changes that begin to escalate at that time (Good, Johnsrude, Ashburner, Henson, Friston, \& Frackowiak, 2001; Grady, Springer, Hongwanishkul, McIntosh, \& Winocur, 2006)
  • Given the high rates of morbidity for such disorders among people with high EA, we will not exclude based on past diagnoses for any of those disorders or based on current drug and alcohol use. However, we will exclude individuals who do not pass a urine toxicology screen during either of the functional magnetic resonance imaging (fMRI) sessions to ensure that the neuroimaging data are as homogeneous and reliable as possible.
  • Participants who cannot undergo an MRI scan will be excluded; contraindications include metal implants (e.g., braces, pins) or metal fragments, pacemakers or other electronic medical implants, claustrophobia, pregnancy, and weight greater than 550 lbs.
