Protecting older people from loneliness during the coronavirus (Covid-19) and other novel infectious disease pandemic
Protecting older people from loneliness during the coronavirus (Covid-19) and other novel infectious disease pandemic
1. To protect community-dwelling older adults from loneliness, we will develop and evaluate two psycho-social interventions for use during times such as the COVID-19 pandemic and other future novel infectious disease pandemics. To meet the huge demand for such interventions during future pandemics, we plan to recruit and train retirees to implement a couple of promising interventions. To establish such a pool of human capital for future crises more easily, we argue that it is crucial to provide scientific evidence of the benefits of volunteerism for retirees. Consequently, the overall objective of this proposed study is to develop and evaluate two psycho-social interventions that are likely to prove mutual benefits to volunteers who will implement the interventions and those who will receive them in a dual randomized controlled trials (RCTs). The specific objectives are as follows: 1. To evaluate the effects of four-week telephone-delivered behavioral activation and telephone-delivered mindfulness interventions on primary (loneliness, social network size, social support) and secondary outcomes (perceived stress, sleep quality, post-traumatic stress disorder, anxiety, and depressive symptoms), relative to a four-week telephone-delivered befriending group using a three-arm RCT with a large representative sample of community-dwelling older adults who are living alone, have household income below the official poverty line, and who are digitally excluded. Data will be collected at baseline and four-week, three-month, and six- month follow-up assessments. 2. To examine the effects of volunteering on the primary and secondary outcomes, as well as cognitive functioning among retirees aged between 50 and 70 years who will be recruited and trained to deliver telephone-delivered behavioral activation, telephone-delivered mindfulness, and telephone-delivered befriending interventions, using a two-arm RCT. Data will be collected at baseline and 6-month and 12-month follow-up assessments. 3. To examine the moderating role of volunteering in the link between social network or social support and loneliness, as well as the association of perceived stress with other secondary outcomes (e.g. depressive and anxiety symptoms) among retirees aged between 50 and 70 years, who will be recruited and trained to deliver the telephone-delivered behavioral activation, telephone-delivered mindfulness, and telephone-delivered befriending interventions, using a two-arm RCT. 4. To examine whether or not the effects of the loneliness interventions (i.e., telephone- delivered behavioral activation, telephone-delivered mindfulness, and the telephone-delivered befriending interventions) and the impacts of volunteering on the primary and secondary outcomes is mediated by changing diurnal salivary cortisol patterns and levels of the salivary C Reactive Protein, using a three-arm and two-arm RCT, respectively. 5. To examine how responses to the different loneliness interventions (i.e. telephone-delivered behavioral activation, telephone-delivered mindfulness and telephone-delivered befriending interventions) depend on genetic markers using four approaches (candidate gene, genome- wide association study (GWAS), biological pathway related single nucleotide polymorphisms (SNPs), and polygenic risk scores) using a three-arm RCTs.pathway related single nucleotide polymorphisms (SNPs), and polygenic risk scores) using a three-arm RCTs.

The inclusion criteria for participants in the RCT on loneliness will be: 1. Aged 65 years and older; 2. Able to communicate through Cantonese over the phone; 3. They have mild or no cognitive impairment; 4. No psychiatric disorder, learning disability, or active suicidal ideation; 5. Living in poverty defined by the official Hong Kong poverty line, i.e., half of median household income adjusted by household size; 6. Living alone; 7. No access to internet; 8. Not engage in regular systematic mindfulness mediation or related mind-body practice (> 2 times per week); 9. Feeling lonely (cut-off >= 6 of 3-item UCLA Loneliness Scale).
