A randomised controlled trial of the Nextdoor Kind Challenge: a study protocol

The KIND Challenge community intervention to reduce loneliness and social isolation, improve mental health, and neighbourhood relationships: an international randomized controlled trial

PURPOSE

Loneliness and social isolation are risk factors for poor health, but few effective interventions are deployable at scale. This study was conducted to determine whether acts of kindness can reduce loneliness and social isolation, improve mental health, and neighbourhood social cohesion.

METHOD

Three randomized controlled trials (RCTs) were conducted in the USA, UK, and Australia, involving a total of 4284 individuals aged 18-90 years old, randomized to the KIND challenge intervention or a waitlist control group. Participants allocated to the intervention were asked to do at least one act of kindness per week within a four-week period. The primary outcome was loneliness and secondary outcomes included measures of social isolation, mental health, and neighbourhood social cohesion.

RESULTS

There was a significant, albeit small, intervention effect after four weeks for reduced loneliness in the USA and the UK, but not for Australia. Relative to controls, KIND challenge participants also showed significantly reduced social isolation and social anxiety in the USA, and reduced stress in Australia. There was also reduced neighbourhood conflict in the USA, increased number of neighbourhood contacts in the USA and Australia, greater neighbourhood stability and feelings of neighbourhood importance in the UK, and better neighbourhood social relationships in Australia.

CONCLUSION

Promoting the provision of social support through small acts of kindness to neighbours has the potential to reduce loneliness, social isolation and social anxiety, and promote neighbourhood relationships, suggesting a potential strategy for public health campaigns.

Non-Deceptive Placebos Can Promote Acts of Kindness: A Randomized Controlled Trial

Placebos have often been used to reduce emotional distress but rarely to increase positive feelings. The present study investigated whether a placebo can promote acts of kindness (AoKs) that are associated with emotional well-being. A total of 160 university students were asked to perform an AoK daily for one week. They evaluated their emotional state (feelings of pleasantness, arousal, satisfaction) directly before and after the AoKs. This was monitored via a smartphone app. One group performed each AoK after taking a non-deceptive placebo; the other group received no placebo. Before and after the one-week program, the participants completed three questionnaires that assessed satisfaction with life, positive/negative affect, and flourishing. The participants reported higher pleasantness directly after engaging in an AoK and more satisfaction with life after the program. The motivation to carry out AoKs decreased strongly over the week. However, placebo receivers completed more AoKs than the no-placebo group. The results indicate that placebo treatment can promote the performance of acts of kindness.

Weaving Social Connectivity into the Community Fabric: Exploring Older Adult’s Relationships to Technology and Place

The wellbeing of older adults is positively impacted by ease of access to social networks and opportunities. In urban fringe communities, longer geographical distances, combined with mobility and health issues, can lead to decreased access to community life. Technology can facilitate socialisation opportunities for older adults living in more geographically isolated locations, but we need to work with communities to better understand how technology can fit into their existing social tapestry and community infrastructure. We conducted an explorative, qualitative study consisting of in-depth semi-structured interviews with members of an urban fringe community (n = 2), and a community mapping focus group (n = 14). Transcripts and mapping materials were analysed thematically, and also the method’s suitability explored. The community mapping proved suitable to uncover the complexity of technology use to support social connectivity. We found that while technology was perceived as valuable by our participants, there were also significant fears and concerns surrounding its use related to the abstract concept of online friendship and the steep learning curve required to master some platforms. Inclusive communities connected by technology require tailored and customised community-led technology initiatives in order to accommodate for the unique social and geographical contexts in which they live. We outline the next steps for future research on technology-supported social connectivity within urban fringe communities.
