Ten studies were included in the meta-analysis for loneliness. The pooled SMCC was 0.350 (95% CI: 0.180–0.520, p < 0.001), indicating a mild to moderate reduction in loneliness following interventions with conversational agents (Figure 2).
Contexto
What changed: Use of autonomous conversational agents including social robots, chatbots, and smart speakers. Comparison: Within-group pre-intervention vs. post-intervention scores across 10 studies. Limits: Estimates rely on within-group pre-post designs without blinded outcome assessment, showing moderate heterogeneity.
