  • Active substance use, including nicotine/tobacco, alcohol, marijuana, recreational drugs, or energy drinks, as assessed by the Drug Use Screening Inventory.
  • Habitual high caffeine intake (>200 mg/day, equivalent to >4 cups of coffee or >2 cans of caffeinated soda per day), as assessed by a caffeine screening question during eligibility screening.
  • Psychotic disorders or active psychotic symptoms, as reported on the Mental Health History Questionnaire (Parent) and the Self-Administered Comorbidity Questionnaire.

About this study

Official title: CONNECT Study: Parent-Adolescent Relationships, Emotional Regulation, and HRV in Adolescents With Depression

This cross-sectional study examines associations among heart rate variability (HRV), emotional dysregulation, and parent-adolescent relationship quality in adolescents with Major Depressive Disorder (MDD). We hypothesize that lower HRV will be linked to greater emotional dysregulation and that more supportive parent-adolescent relationships will correlate with higher HRV. Participants will wear a Fitbit Charge 5 during nighttime sleep for 7 consecutive nights and complete validated measures of emotional regulation and relationship quality.

Depression

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Nighttime Heart Rate Variability (RMSSD)

    Average nighttime RMSSD reflecting parasympathetic autonomic activity, passively collected via wearable device during sleep. Emotional dysregulation assessed as a continuous predictor using the DERS-36 total score.

    Measured: 7 consecutive days and nights

Secondary outcomes (1)
  1. Resting Heart Rate (RHR)

    Average resting heart rate (beats per minute) derived from wearable device data, reflecting baseline autonomic arousal and physiological stress.

    Measured: 7 consecutive days

Questions about this trial

What is this clinical trial studying?

An observational study of Emotional Dysregulation and HRV, run by University of Texas Southwestern Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?

Contact Emine Rabia Ayvaci, MD (650-804-0602, Emine.Ayvaci@utsouthwestern.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Nighttime Heart Rate Variability (RMSSD) (time frame: 7 consecutive days and nights). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
