PMID 34007254WHAT IT FOUND
Nonpharmacological interventions like animal-assisted therapy, social engagement programs, and behavioral activation can improve social participation and reduce depressive symptoms in adults.
However, evidence for improved quality of life is weak, and no single program was proven superior due to varied study designs.
Key findings
01Four specific intervention programs (animal-assisted therapy, social engagement programs, religious activity, and a behavioral change program for head and neck cancer) demonstrated visible positive behavioral changes in social participation.
02All included intervention programs reported a reduction in depressive symptoms, though the significance varied by program and follow-up time.
03Only one program (community-based psychosocial group intervention) showed significant improvement in quality of life, while others had insufficient data or non-significant results for this outcome.

What it does not show
The review could not determine which program was most effective due to the diversity of participants, interventions, and outcome measures. Many studies had high or unclear risk of performance and detection bias because blinding is difficult in behavioral interventions. The definition of social participation varied across studies, and some included participants outside the core adult depression population (e.g., adolescents or those with severe mental illness). Most studies relied on self-report measures for social participation, which may not accurately reflect objective behavioral change. The review excluded qualitative studies and non-English articles, potentially missing relevant perspectives or evidence.

The easy way to misread this
Do not assume that all nonpharmacological interventions will improve quality of life or life satisfaction. The review found that only one program significantly improved quality of life, and improvements in life satisfaction were not statistically significant in the programs that measured it. While depressive symptoms decreased across all programs, the impact on broader well-being outcomes is not guaranteed.
