About this study

Official title: Effects of Contact to a Dog During Standardised Stressful Situations

The investigators will conduct an experimental study comparing responses of healthy participants in two test situations where they are subjected to mild stress. The study design is a randomised controlled crossover design nested within two groups - one with a dog present and another without a dog present. The participants will be randomly allocated to two groups (with dog and without dog) and the participants will receive both test situations on the same day. During the two test situations the participants will be subjected to a classical stress test , and exposed to tolerable pain, as well as periods with relaxation.

Read the detailed description

The study design is a randomised controlled crossover design, nested within two groups - one with a dog present (Dog) and another without a dog present (No Dog). Both groups will be subjected to a classical stress test - the Maastricht Acute Stress Test (MAST) and a pain test with periods of relaxation in between. The participants will be subjected to both test situations on the same day and in the same order.

On the test day, background information and baseline measures (baseline period, duration: 40 minutes) will be collected, whereafter the participants rest for 30 minutes (pre-intervention rest period). After this the participants are subjected to the two test situations, pain test (60 minutes, including calibration and two separate tests sessions) and MAST (15 minutes, including 5 min introduction) with 30 minutes of relaxation in between and a 40 min post-rest period The participants' interaction with the dog is recorded using quantitative behaviour sampling using predefined behavioural categories.

Most physiological and all behavioural measures are recorded continuously throughout test situations and relaxation, in order to be able to study the response to the stress situations and recovery, and the response to contact with dog, and to psychological responses. Some physiological measures obtained before and after each test situation.

Below the exact time schedule of the test day is shown and these times will be refered to when the outcome measures are described. The "Baseline period" (40 minutes) and the last 10 minutes where the equipment for physiological measures is removed is not included in the duration of the test period (174 minutes). All times are given in minutes.

Baseline period (40 minutes - not part of total test period)

  • Pre-intervention period (start t = 0; end t = 30)
  • Calibration for pain test (start t = 30, end t = 35)
  • Rest period 1 (start t = 35, end t = 47)
  • Pain test 1 (start t = 47, end t = 52)
  • Post-pain test 1 (start t = 52, end, t= 62)
  • Rest period 2 (start t = 62, end t = 74)
  • Pain test 2 (start t = 74, end t = 79)
  • Post-pain test 2 (start t = 79, end t = 89)
  • Rest period 3 (start t = 89, end t = 119)
  • MAST test (incl. introduction (start t = 119, end t = 134)
  • Rest period 4 (start t = 134, end t = 174)

Questions about this trial

What is this clinical trial studying?

A study testing Dog and No Dog in people with Physiological Stress Responses to Standardises Stress Situations and Psychological Responses to Standardised Stress Situations, run by University of Aarhus at 1 site in Denmark.

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

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Physiological measure, heart rate (time frame: Measured continuously throughout the total test period of 174 minutes (starting in the pre-intervention period and during the following test situations and all resting periods)]). The study lists 53 primary outcomes in all. 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Nov 2021.
