Introduction: Effective, scalable interventions to address depression and loneliness and improve the quality of social relationships are needed for public health in pandemic and non-pandemic contexts. Towards this end, a randomized, controlled trial tested a mobile-based intervention, derived from social psychological and relationship science, for improving relational well-being and decreasing depression and loneliness. Methods: Participants were randomly assigned to either intervention (n = 719) or assessment only (n = 701) conditions and completed daily diary surveys for 28 days in the midst of the first wave of the Covid-19 pandemic. In the middle 14 days of the study, intervention participants received daily text-message suggestions for improving relational and mental well-being. Results: Results indicated that the intervention decreased depression and loneliness and improved relationships during the intervention period but these changes were not sustained when the intervention ceased. Discussion: Results are encouraging in that evidence-based suggestions can be scaled effectively but additional efforts are required to sustain improvements over time.

在 Covid-19 大流行期间减少抑郁和孤独感并提高关系质量的简短移动干预措施

简介：大流行和非大流行背景下的公共卫生需要有效的、可扩展的干预措施来解决抑郁和孤独感并改善社会关系的质量。为此，一项随机对照试验测试了一种源自社会心理学和关系科学的基于移动的干预措施，以改善人际关系幸福感并减少抑郁和孤独感。方法：参与者被随机分配到干预 (n = 719) 或仅评估 (n = 701) 条件下，并在第一波 Covid-19 大流行期间完成 28 天的每日日记调查。在研究的中间 14 天，干预参与者每天都会收到短信建议，以改善人际关系和心理健康。结果：结果表明，干预在干预期间减少了抑郁和孤独感，改善了人际关系，但当干预停止时，这些变化并没有持续下去。讨论：结果令人鼓舞，因为基于证据的建议可以有效地扩展，但需要额外的努力来维持随着时间的推移而改进。
