What This Study Did, in Plain Language

What Was Tested

This registered not phased trial tested Oxytocin.

The main aim of the study is to investigate the effects of ±3,4-methylenedioxymethamphetamine (MDMA; ecstasy) on social and emotional processing in healthy humans.

It had 1 arm (groups): Single group (experimental).

Healthy volunteers received all drug conditions (MDMA, oxytocin, and placebo) using a within-subjects design.

The registry classes the interventions as drug.

Who Took Part

Enrollment: 65 actual participants took part.

It was open to people of any sex aged from 18 years up to 35 years.

Healthy volunteers could join, not only people with the condition.

Examples of who could join: High school education,. No psychiatric disorders,. Occasional MDMA use.

The full record lists 7 inclusion and 4 exclusion criteria; among the exclusions: current medications,; night shift work,; abnormal electrocardiogram,.

How the Study Was Run

The set-up was single-group and double-blind.

Blinding on both sides kept the participants and researchers unaware of who received Oxytocin.

Everyone received the same intervention, so there was no separate comparison group inside the trial.

Those kept unaware of assignments: participant and investigator.

It started in 2010-07 with completion listed for 2013-03.

It ran at 1 site in United States.

Its stated primary purpose is basic science.

What Was Measured

Researchers chose this as the main measure: Emotional Recognition (MDMA) (time frame: 15 minutes during each session). Emotional Recognition (Oxytocin) (time frame: 15 minutes during each session). Emotional Recognition (Placebo) (time frame: 15 minutes during each session).

It also tracked 21 secondary outcomes, for example Subjective Response to MDMA (Ratings of 'Feel Drug'), Subjective Response to Oxytocin (Ratings of 'Feel Drug'), Subjective Response to Placebo (Ratings of 'Feel Drug'), Subjective Response to MDMA (Ratings of 'Feel High'), Subjective Response to Oxytocin (Ratings of 'Feel High') and Subjective Response to Placebo (Ratings of 'Feel High').
