While loneliness may motivate individuals to approach others, it may simultaneously increase their focus on self-preservation, resulting in egocentric behavior. Since the evidence linking loneliness and prosociality is inconclusive, the current meta-analysis aims to explore this relationship. Through a systematic search of databases, we identified 35 studies involving 44,764 participants. A small effect size for a negative correlation between loneliness and prosociality ( = -0.12, 95% CI: [-0.19, -0.05]) was found using the random effects model. The effect was not moderated by participants' sociodemographic characteristics or the WEIRDness of the sample but differed between types of measurement and forms of prosocial behavior. Our findings highlight the importance of understanding the processes perpetuating the link between loneliness and decreased prosociality, as this tendency may pose difficulties in restoring social connections, cooperating with others, or aiming for common goals.

A growing body of literature suggests that prosocial behavior, or behavior intended to help others, benefits well-being. However, modern society often places a greater emphasis on self-focused acts in the pursuit of well-being. To understand the effects of these differing forms of kindness (to others or the self), we conducted a 2-week intervention study of a community sample during the COVID-19 pandemic in 2020.

Objective: This study evaluates the effects of an act of kindness intervention on increasing daily social contact and reducing loneliness among community adults experiencing loneliness. It also explores heterogeneity in effects and potential moderators, including individual differences in baseline social health and intervention implementation.
Method: In a randomized controlled trial, 208 adults were randomly assigned to perform daily acts of kindness for others (Kindness condition) or take a short break for themselves (Control condition) for 2 weeks.

Objectives: Social connection is crucial for well-being and health. Dyadic meditations-contemplative practices carried out by two people together-have the potential to foster connection.

Past research has suggested that isolation is associated with poorer psychological well-being, an issue of particular importance given the quarantines imposed during the recent coronavirus pandemic. The aim of the present randomized clinical trial was to evaluate the effectiveness of different strategies for coping with loneliness and distress during isolation. In the online study, participants ( = 330) from a nationwide and international sample were randomly assigned to practice one of six strategies (i.
