The COVID-19 lockdown has had a massive psychological impact on mental health in the general population, with increases in anxiety, depression, and post-traumatic stress disorder. Spiritual well-being, specifically peace and meaning, has already been identified as one of the main protective factors for these disorders in the COVID-19 context. The aim of the present study is to identify facilitating elements for peace and meaning during the COVID-19 lockdown in Spain. Online surveys were used to obtain data from a sample of 3480 Spanish people. Self-compassion and social support were positively related with peace and meaning, while loneliness and perceived discrimination were negatively related. The model for peace and meaning was statistically significant, explaining 47% of the variance. The significant variables were self-kindness, family support, mindfulness, and sense of belonging having a positive association and loneliness a negative one.
