Motivation, comfort, calm
The researchers found statistically significant decreases in UCLA Loneliness Scale scores from pre-ESA (mean [SD],59.20 [9.47]) to 12 months (49.90 [13.66], P = .004). The eta-squared statistic (.62) indicated a large effect size.
For 18 of the 20 items on the loneliness scale, mean values were lower after the intervention than before the intervention. Of these, four were statistically significant.
A statistically significant decrease in BDI total scores was also seen from pre-ESA to 12 months (21.09 [8.43] to 14.64 [7.03], respectively; P = .03). The eta-squared statistic (.41) indicated a large effect size.
Of the 21 items on the BDI scale, the mean value was lower for 19 after the intervention. Of these, five were statistically significant.
Similarly, a statistically significant decrease in BAI score was found from pre-ESA to 12 months (23.55 [9.81] to 17.73 [11.79], P = .049). The eta-squared statistic (.36) indicated a large effect size, although there were no statistically significant changes in individual item scores.
The researchers found “observable patterns” of decreases in cortisol and increases in oxytocin after the 10-minute enjoyable ESA interactions. The highest oxytocin increase occurred at 12 months; however, these improvements did not reach statistical significance.
Participants offered open-ended statements about the positive impact of their ESA on their mental health, Dr. Hoy-Gerlach said. “For example, they described feeling motivated to take better care of themselves because their ESA needed them. Some described feeling ‘comforted,’ distracted from symptoms, soothed, and calmed.
“There is definitely a place for ESAs, especially with mental health post pandemic, when we need all the resources that we can for those who can benefit,” she added.
Postpandemic mental health
Commenting on the study for this news organization, Christine Crawford, MD, MPH, assistant professor of psychiatry, Boston University, observed that ESAs “are not on the radar for a lot of clinicians, and a lot of clinicians don’t know about the science [supporting their use] or what an emotional support pet entails.
“ besides traditional forms of treatment, such as medication and therapy. Even a little relief is important, and having an emotional support pet is a good option,” said Dr. Crawford, associate medical director of the National Alliance on Mental Illness. She was not involved with the study.
The Kenneth A. Scott Charitable Trust provided grant funding. Dr. Hoy-Gerlach, her coauthors, and Dr. Crawford have disclosed no relevant financial relationships.
