Among homeless individuals, does owning a pet improve their mental health?
Clinical bottom line
Category of research question
The number and type of study designs reviewed
Fifteen (eight qualitative assessments, two cross-sectional quantitative studies, three qualitative/cross-sectional studies, and two scoping/systematic reviews)
Strength of evidence
Homeless individuals who own pets reported improvement in their mental health status by having fewer symptoms of depression, reduced feelings of loneliness, reduced stress, increased feelings of happiness, and decreased intentions of suicide, all as a result of owning a pet.
However, homeless individuals who own pets may suffer a decrease in mental health due to the loss or anticipated loss of their pet
It is concluded among qualitative and cross-sectional studies that there are clearly multiple benefits to mental health associated with pet ownership among homeless individuals. However, the lack of quantitative, longitudinal, and/or experimental studies in this topic prevents a causative relationship from being established and caution should be exercised when interpreting the results as pet ownership causing an improvement in mental health
The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
