Pet Ownership, Depression, Anxiety, Well-Being, and Cognitive Functioning in Older Adults: Cross-Sectional Study.
Article in JMIR formative research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Depression, anxiety, and cognitive decline are prevalent concerns among older adults and can negatively affect their well-being. Pet ownership has been proposed as a potential protective factor, but inconsistencies remain in the current literature. Objective: The study aims to compare symptoms of depression, anxiety, and levels of psychological well-being between older pet owners and non-pet owners. Additionally, we compared the cognitive functioning and cognitive reserve between these 2 groups of older individuals. Methods: This cross-sectional study included 215 community-dwelling older adults aged ≥59 years (mean 69.13, SD 6.89). Participants completed a sociodemographic questionnaire, the Modified Telephone Interview for Cognitive Status, Cognitive Reserve Index Questionnaire, Mental Health Continuum-Short Form, Geriatric Depression Scale-15, and Geriatric Anxiety Inventory. The data were collected via video calls through WhatsApp and analyzed using the JASP software. Group comparisons (pet owners vs nonowners) were conducted using the Mann-Whitney U test, followed by rank-biserial correlation for effect sizes (α=.05). Results: The sample consisted of 114 (53.0%) older adults pet owners and 101 (46.9%) older adults who did not own pets. Among the pet owners, 77.2% (n=88) were female, and 57.9% (n=66) were married or in common-law marriages. In the non-pet owners' group, 71.3% (n=72) were female, and 46.5% (n=47) were married or in common-law marriages. Pet owners showed lower depression symptoms (Geriatric Depression Scale-15: mean 2.33 vs 3.00 non-owners; U=4714, P=.02; rb=-0.18, 95% CI -0.326 to -0.028), indicating a small effect. No significant group differences were observed for anxiety (Geriatric Anxiety Inventory: mean 5.33 vs 4.92, P=.52), psychological well-being (Mental Health Continuum-Short Form: mean 68.21 vs 67.46, P=.43), cognitive performance (Modified Telephone Interview for Cognitive Status: mean 24.74 vs 24.30, P=.60), or cognitive reserve (Cognitive Reserve Index Questionnaire: mean 123.82 vs 123.28, P=.95). Conclusions: The pet owner group presents fewer symptoms of depression in comparison to the non-pet owner group. Although no differences were observed in anxiety, well-being, cognitive functioning, or cognitive reserve, these findings suggest that pet companionship correlates with better emotional outcomes in later life. Future longitudinal studies are needed to clarify causal pathways and examine whether the frequency and quality of interactions with pets influence these outcomes.
