01Most included studies reported no significant improvement in caregiver loneliness.
02One engaged coaching study reported a standardized response mean of 0.63 for loneliness.

What it does not show
Only English studies were included, so relevant non-English work may be missing. No meta-analysis was done because sample sizes were small, designs varied, and most results were not statistically significant. Included studies had small samples, limited geographic spread, and poor racial, ethnic, and gender diversity. Several studies lacked control groups, randomization, or clear reporting of blinding and allocation. Only one RCT was rated low risk of bias, two had some concerns, and only one quasi-experimental study met all appraisal criteria. Interventions often lacked a stated theoretical rationale. Follow-up timing varied, and long-term benefits were not usually assessed. Self-reported outcomes and technology access may bias or limit results.
Declared interests
The authors reported nothing to disclose.
The easy way to misread this
Do not conclude that remote psychosocial interventions reliably reduce caregiver loneliness. Seven included studies showed no significant loneliness improvement, and the review did not combine results in a meta-analysis.
