Teen Vulnerability to Irritability: Brain and Estrogen Changes (TeenVIBE)

August 20, 2026 updated by: University of North Carolina, Chapel Hill

Neurobiological Mechanisms of Susceptibility to Estradiol Fluctuation in Female Adolescents at Risk of Suicide: An Experimental Approach

Purpose: Risk of severe psychopathology increases dramatically during adolescence, especially for females. Changes in ovarian steroids across the menstrual cycle produce windows of vulnerability to mood disturbances, particularly during the abrupt withdrawal of estradiol (E2) and progesterone (P4) prior to menses onset. Irrefutable evidence links stress with affective symptoms, potentially mediated by E2-related modifications of frontolimbic connectivity and prefrontal gamma-aminobutyric acid (GABA) inhibitory signaling. The primary objective of this project is to empirically test the impact of E2 and P4 change on vulnerable brain networks associated with irritability and other depressive symptoms in female adolescents at risk of suicide.

Participants: The investigators will enroll 50 female adolescents ages 12-16 who are at risk of suicide (i.e., moderate depressive symptoms), and are eligible to receive oral contraceptives and undergo MRI imaging.

Procedure: Using a randomized, placebo-controlled, cross-over design, participants will be studied under two conditions: 8 weeks of E2 and P4 stabilization (continuous combined oral contraceptive (COC) to prevent perimenstrual withdrawal) and 8 weeks of placebo, with a 1-month washout after each condition. Each condition will include: 1) daily samples of E2 and P4 urinary metabolites, 2) daily symptom ratings(e.g., irritability, negative affect and suicidal thoughts and behaviors (STBs)), and 3) a neuroimaging session with MRI and magnetic resonance spectroscopy (MRS).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Irritability Symptoms (average Brief Irritability Test (BITe) across each 8-week condition)
Time Frame: Average Brief Irritability Test (BITe) will be collected daily across the complete study duration (week 1 -24).
The Brief Irritability Test (BITe) is a 5-item self-report instrument developed to measure irritability as a distinct emotional construct, defined by increased susceptibility to frustration, annoyance, and anger in response to minimal provocation. Participants rate each item (e.g., feeling grumpy, easily annoyed, on edge) using a 6-point Likert scale ranging from Never (1) to Always (6). Total scores range from 5 to 30, with higher scores indicating greater irritability. BITe total score is calculated as the sum of the five items.
Average Brief Irritability Test (BITe) will be collected daily across the complete study duration (week 1 -24).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Irritable behavior (point subtraction aggression paradigm (PSAP)
Time Frame: During the neuroimaging session (inside the scanner) at week 8 (1 time point during the last week of condition 1) and week 20 (1 time point during the last week of condition 2)
The Point Subtraction Aggression Paradigm (PSAP) is a computerized task measuring reactive aggression in response to provocation. Participants believe they compete with an opponent to earn points. They may earn points, subtract a point from the opponent (aggressive response), or activate protection. Aggression is quantified as the number of point-subtraction responses, with higher values indicating greater aggressive behavior. Scores range from 0 to the total number of opportunities/response trials within the task session, depending on task duration and provocation frequency.
During the neuroimaging session (inside the scanner) at week 8 (1 time point during the last week of condition 1) and week 20 (1 time point during the last week of condition 2)
medial prefrontal cortex GABAergic activity
Time Frame: During the neuroimaging session (inside the scanner) at week 8 (1 time point during the last week of condition 1) and week 20 (1 time point during the last week of condition 2)
Scanning will be conducted using a 7 Tesla Siemens MAGNETOM scanner (Siemens, Erlangen, Germany) with a Nova Medical 32-channel receive array head coil to obtain high-quality spectra from the medial prefrontal cortex (mPFCpref, 20 × 20 × 20 mm). The MRS voxels processed within the mPFC will be passed to the metabolite quantification process to quantify the level of gamma-aminobutyric acid (GABA).
During the neuroimaging session (inside the scanner) at week 8 (1 time point during the last week of condition 1) and week 20 (1 time point during the last week of condition 2)
Functional connectivity between amygdala and frontal network (medial, ventrolateral, ventromedial prefrontal cortex).
Time Frame: During the neuroimaging session (inside the scanner) at week 8 (1 time point during the last week of condition 1) and week 20 (1 time point during the last week of condition 2)
Connectivity strength (-1 to +1) between the amygdala and frontal network (medial, ventrolateral, ventromedial prefrontal cortex).
During the neuroimaging session (inside the scanner) at week 8 (1 time point during the last week of condition 1) and week 20 (1 time point during the last week of condition 2)
