Animal-assisted therapy (AAT) shows promise in reducing anxiety for individuals with disabilities, chronic illnesses, or hospitalizations. While effective short-term across diverse groups, more research is needed on long-term effects and optimal integration into healthcare.
Area of Science:
- Psychology
- Veterinary Medicine
- Healthcare Management
Background:
- Anxiety is common in individuals with disabilities, chronic illnesses, or during hospitalization.
- Current healthcare often inadequately addresses this prevalent anxiety.
- Animal-assisted therapy (AAT) is a proposed complementary intervention with fragmented evidence.
Purpose of the Study:
- To systematically review the evidence on AAT for anxiety reduction in specific populations.
- To synthesize findings across diverse methodologies and patient groups.
- To identify gaps in current research regarding AAT's efficacy and application.
Main Methods:
- Systematic review following PRISMA 2020 guidelines.
- Searched four major databases (Scopus, APA PsycInfo, Web of Science, PubMed) for studies from 2013-2023.
- Included empirical studies on AAT by professionals using domesticated animals, focusing on anxiety outcomes in target populations.
Main Results:
- Thirty-one studies were included, primarily using dogs and horses.
- Most AAT interventions reported significant short-term anxiety reductions.
- Randomized clinical trials showed superior efficacy compared to controls across various conditions (PTSD, pediatrics, chronic illness, etc.).
Conclusions:
- AAT is a promising complementary therapy for anxiety in clinical and healthcare settings.
- Evidence supports short-term anxiolytic effects in diverse populations.
- Further research is needed to standardize interventions, understand mechanisms, and evaluate long-term outcomes.
