What is being measured

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

  1. Change of Intrusive Memories in the following four days after the intervention

    Influence of oxytocin on the development of intrusive memories measured with an intrusion diary

    Measured: four consecutive days

Secondary outcomes (3)
  1. Noradrenergic System (measured with salivary alpha-amylase - u/ml)

    Influence of oxytocin on the noradrenergic system measured with salivary alpha-amylase

    Measured: Day 1

  2. Hypothalamic-pituitary-adrenal (HPA) axis (measured with salivary cortisol - nmol/L)

    Influence of oxytocin on the HPA-axis measured with salivary cortisol

    Measured: Day 1

  3. Polygenic Risk Score

    Influence of polygenic risk score on development of intrusive memories

    Measured: four consecutive days

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of Intrusive Memories in the following four days after the intervention (time frame: four consecutive days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03875391, which also lists 1 linked publication.

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.
