“…As many researchers focus on health-related interventions (Baldwin et al, 2017;Fredrickson, 2000;Gick, 2011;Hilton and Johnston, 2017;Lai and Ma, 2016;Lennefer ., 2019;Luthans et al, 2006;Ryff et al, 2015;Sibulwa et al, 2019), we hope that our study at least humbly contributed to the understanding of the association between the number of diseases, psychological capital, and psychological wellbeing, and this might have an added value for health intervention planning. We hope that this research provided some empirical evidence to implement health-related PsyCap or similar interventions on a large scale as strong self-efficacy, hope and resilience proved to be beneficial for the health of people of different ages (Fredrickson, 2000;Luthans et al, 2006;Marsh et al, 2019;Ueno et al, 2020;Van Dick et al, 2017;Varas et al, 2019).…”
