Moreover, the high genetic divergence to Diplodiscus spp. (10.06–10.84%) cast doubts on the placement of Catadiscus within Diplodiscidae. Hence the species composition of the Diplodiscidae should be re-evaluated in further studies using a broader spectrum of related taxa. Although older adults often experience negative life events or loss experiences, they rarely experience large decreases in their quality of life or well-being. Emotionally satisfying relationships in older adults may serve as a protective factor that reduces the impact of negative events in decreasing well-being. The availability of these close social contacts is essential, and their potential for alleviating feelings of loneliness after negative events could have an important role in promoting well-being. The aim of this study was to test the hypothetical moderation and mediation effects of social and emotional loneliness on the occurrence of negative old-age life events and well-being in later life. This was a cross-sectional survey conducted as part of the Detection, Support and Care for older people - Prevention and Empowerment research project (2015-2018). Participants were community-dwelling older adults in Flanders (Belgium). The sample composed of 770 participants aged 60 years and over. Participant demographics, social and emotional loneliness, and subjective well-being were measured. Moderation and mediation analyses were performed using the regression-based approach as conducted by Hayes and Rockwood (2017). Results indicated that a low degree of (social) loneliness is a protective, moderating factor and (emotional) loneliness is a mediating factor on the effects of negative life events on well-being in later life. Findings highlight the importance of emotionally and socially
