“…While some differences in physical health outcomes emerged in our RCT between those assigned to the intervention and control conditions at 6-month follow-up (blinded for review), the psychosocial benefits found in previous research were not observed (i.e., higher levels of life satisfaction; higher self-esteem, personal growth, and purpose in life; lower rates of depression; greater social connectedness and social support: Carr et al, 2018;Cho et al, 2018;Greenfield & Marks, 2004;Han & Hong, 2013;Heo et al, 2017;Lum & Lightfoot, 2005;Pilkington et al, 2012;Wahrendorf et al, 2008). These results were partially supported by the second RCT, in which older adults prompted to increase their engagement in voluntary work did not report increased self-efficacy, perceived autonomy, or purpose in life, but did report fewer depressive symptoms at 6-month follow-up (Jiang et al, 2020). Given it has been suggested that the benefits of volunteering are most likely to emerge "in the medium to long term, when social networks and attitudes towards life have had the chance to change" (Russell et al, 2019, p. 119), the 6month follow-up period adopted by both these RCTs may have been too short to enable significant change to occur across many of the assessed psychosocial variables.…”
