About this study

Official title: Measuring the Effects of Different Intensities of Contact to Dogs

The study aims to identify and quantify objective non-invasive measures of the immediate effect of contact with dogs in a standardized experimental setup. Employing a within-subject design, the study includes healthy participants that are exposed to three different levels of contact to a dog compared with a no-dog control condition while obtaining measures of both physiological, behavioral, and psychological effects.

Read the detailed description

Using a within-subjects design, we will compare four standardised and controlled test situations with different levels of dog contact:

  1. visual (V), 2) tactile and visual (TV), 3) tactile, visual, interaction (TVI), and 4)control (C).

The participants will be subjected to all four test situations on the same day, and will be randomly allocated to test order.

On the test day, we collect background information and baseline measures for the participants (baseline period, duration: 50 minutes), whereafter they rest for 30 minutes (pre-intervention rest period). After this the participants are subjected to the four test situations (10 minutes each) that are followed by rest intervals (30 minutes each).

The participants' interaction with the dog during the 10-minute test situations are standardised according to the specific contact treatment. Most physiological and all behavioural measures are recorded continuously throughout each test in order for us to link the "dosage" of dog (the different levels of contact) with the psychological responses and some physiological measures obtained before an after each test situation.

Below is shown the exact time schedule of the test day, that we refer to when describing the outcome measures. The baseline period (30 minutes) is not included in the total test period (total duration= 190 minutes), that consist of a pre-intervention and intervention period.

  • Baseline period (50 minutes - not part of total test period)
  • Pre-intervention period (start, t=0 minutes; end t= 30 minutes)
  • Test situation 1 (start, t=30 minutes; end, t=40 minutes)
  • Rest period 1 (start, t=40 minutes, end, t= 70 minutes)
  • Test situation 2 (start, t=70 minutes; end, t=80 minutes)
  • Rest period 2 (start, t=80 minutes, end, t= 110 minutes)
  • Test situation 3 (start, t=110 minutes; end, t=120 minutes)
  • Rest period 3 (start, t=120 minutes, end, t= 150 minutes)
  • Test situation 4 (start, t=150 minutes; end, t=160 minutes)
  • Rest period 4 (start, t=160 minutes, end, t= 190 minutes)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Different intensities of contact to dogsOther

    Each subject is exposed to four test situations of 10 minutes. Three situations with increasing intensity of dog contact, and one control test situation with no contact to a dog. The order of the test situations is random and with 30 minute washout in-between

    A video recording of the test persons behaviour is analysed for frequency of predefined behavioural elements Postures: sitting, standing walkning Touching the dog: being in physical contact with the dog with tha hand or another part of the body Looking at the dog: Having head turned towards the dog Talking to the dog: Directing talk directly at the dog, as opposed to the person present

    Measured: Measured continuously throughout the total test period of 190 minutes (through the pre-intervention period, the four test situations and all resting periods)

  2. Quantitative behavioural measures - duration of behavioural elements

    A video recording of the test persons behaviour is analysed for the duration (seconds) of predefined behavioural elements Postures: sitting, standing walkning Touching the dog: being in physical contact with the dog with tha hand or another part of the body Looking at the dog: Having head turned towards the dog Talking to the dog: Directing talk directly at the dog, as opposed to the person present

    Measured: Measured continuously throughout the total test period of 190 minutes (through the pre-intervention period, the four test situations and all resting periods)

Questions about this trial

What is this clinical trial studying?

A study testing Different intensities of contact to dogs in people with Physiological Responses to Contact With Dogs and Psychological Responses to Contact With Dogs, 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 190 minutes (through the pre-intervention period, the four 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?

On the ClinicalTrials.gov record for NCT04696419, 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.

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.
