The role of the endogenous oxytocin system under psychosocial stress conditions in adolescents suffering from anxiety disorder: study protocol for a parallel group controlled trial

What Was Tested

This clinical study looks at Oxytocin.

The present study is a single-center experimental observation study to investigate the reactivity of the endocrinological system to a psychosocial stressor (TSST). 32 children and adolescents (11-18 years) suffering from anxiety disorder will be compared to a matched healthy control group.

Why It Was Studied

A particular focus is given to the neuropeptide oxytocin with its anxiolytic and stress-buffering effect and the resulting therapeutic potential for anxiety disorders.

Even though anxiety disorders are the most prevalent mental health disorders in childhood and adolescence worldwide, the reactivity of the endogenous oxytocin system to an acute stressor (Trier Social Stress Test, TSST) has so far only been investigated in healthy children.

Who Took Part

The abstract describes 32 children taking part.

The age groups tagged for this paper are children and teenagers.

After a detailed psychological assessment, saliva samples will be taken to measure oxytocin levels before and after psychosocial stress exposure at eight different time points.

How the Study Was Run

The researchers set it up as a randomized study.

Because people in this Oxytocin study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Additionally, the stress hormone cortisol will be analyzed according to the same procedure.

What Was Measured

Even though anxiety disorders are the most prevalent mental health disorders in childhood and adolescence worldwide, the reactivity of the endogenous oxytocin system to an acute stressor (Trier Social Stress Test, TSST) has so far only been investigated in healthy children.

What This Means in Plain Language

The paper is a randomized study of Oxytocin in 32 children.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

Results are reported in around 3 sentences of the abstract; we leave them to the paper itself rather than summarise them.
