Assessing Mechanisms of Anxiety Reduction in Animal-assisted Interventions

Status Completed

Clinical Trial Summary

Adolescence and young adulthood is a critical period for the development of social anxiety, which is often linked to other mental health challenges such as depression, mood disorders, and substance abuse. Initial evidence suggests that interacting with animals can reduce stress and anxiety, but no research has tested whether this benefit extends to adolescents at risk for social anxiety disorder. Additionally, researchers and clinicians do not understand what mechanism is responsible for anxiety reduction in animal-assisted interventions (AAIs). Therefore, the objectives of this study are to explore the specific mechanisms by which interacting with a therapy dog reduces anxiety, and to test whether such an interaction reduces anxiety in adolescents with varying levels of social anxiety.

Clinical Trial Description

The specific aims of this project are to (1) test the mechanisms by which AAIs reduce anxiety, and (2) determine if the anxiolytic effect of social and physical interaction is moderated by level of pre-existing social anxiety. To achieve these aims, 75 adolescents (age 13-17) will undergo a well-validated laboratory-based social evaluative stressor, the Trier Social Stress Task for Children, and be randomly assigned to one of three conditions: 1) no interaction with a dog (control condition), 2) social interaction only (no physical interaction) with a therapy dog; or 3) social interaction plus physical interaction with a therapy dog. Using a multivariate approach, three levels of outcome data will be collected: a) self-reported experience (anxiety), b) autonomic physiology (heart rate), and c) behavioral performance (error rates on mental math task). In addition, the interactions will be videotaped and behavioral coding will be used to explore the specific social behaviors between the participant and the dog that may predict anxiety reduction (such as frequency or type of social referencing or physical contact). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
