Objective:
To evaluate the efficacy of Cognitive Behavioral Therapy (CBT) on improving loneliness among older adults.
Design:
A systematic review and meta-analysis.
Methods:
A systematic search was conducted across 10 electronic databases from their inception to June 21, 2025, to identify eligible randomized controlled trials (RCTs). Studies included older adult participants aged 60 years or above. Two reviewers independently performed the screening process, data extraction, and quality assessment of the selected studies. All statistical analyses were carried out using Stata version 18.0.
Results:
Eight RCTs involving 720 participants were included. Pooled analysis revealed a significant and large effect of CBT on improving loneliness among older adults (SMD = -1.00, 95 % CI, -1.59 to -0.42, p < 0.001; low-quality evidence), though substantial heterogeneity was present (I² = 90.5 %). Subgroup analyses indicated that shorter intervention duration (≤12 weeks) (SMD = -1.41, 95 % CI: -2.51 to -0.32, p = 0.011), group-based format (SMD = -1.49, 95 % CI: -2.63 to -0.36, p = 0.010), and online delivery (SMD = -1.51, 95 % CI: -3.93 to 0.92, p = 0.233) may enhance intervention effectiveness. Subgroup analyses also revealed differences across settings. CBT interventions were effective among community-dwelling older adults (SMD = -0.91, 95 % CI: -1.46 to -0.35, p = 0.001), whereas no significant effect was observed among institution-dwelling populations.
Conclusion:
CBT was associated with improvements on loneliness among older adults. However, given the substantial heterogeneity observed across studies, these pooled estimates should be interpreted as exploratory rather than definitive. Subgroup findings suggest that intervention format, intervention duration, delivery modality and settings may influence outcomes. Further well-designed rcts are needed to confirm the effectiveness.
Insights
Cognitive Behavioral Therapy (CBT) significantly reduces loneliness in older adults. However, results varied, suggesting intervention format, duration, and setting influence effectiveness, necessitating further research.
Area of Science:
- Gerontology
- Psychiatry
- Mental Health
Background:
- Loneliness is a prevalent issue among older adults, impacting overall well-being.
- Effective interventions are crucial to mitigate the negative consequences of social isolation in this demographic.
Purpose of the Study:
- To systematically review and meta-analyze the efficacy of Cognitive Behavioral Therapy (CBT) for reducing loneliness in older adults.
- To explore factors influencing CBT effectiveness in this population.
Main Methods:
- Systematic search of 10 electronic databases for randomized controlled trials (RCTs) involving adults aged 60+.
- Independent screening, data extraction, and quality assessment by two reviewers.
- Meta-analysis using Stata v18.0.
Main Results:
- Eight RCTs with 720 participants were included, showing a significant large effect of CBT on reducing loneliness (SMD = -1.00).
- Substantial heterogeneity (I² = 90.5%) was noted, with potential benefits from shorter durations (≤12 weeks), group formats, and online delivery.
- CBT was effective in community-dwelling but not institution-dwelling older adults.
Conclusions:
- CBT shows promise in improving loneliness among older adults.
- Findings on intervention characteristics (format, duration, delivery, setting) are exploratory due to heterogeneity.
- Further high-quality RCTs are required to confirm these findings and optimize CBT interventions.
