Within the international network CEVI, the present study explores the relationship between the personal life events and autobiographical memory and well-being. The CEVI instrument was applied in two different samples from different contexts, stratified in five different age groups: 1) Basque Country (N = 267, age range 20-88 years, mean age M = 38.57, DT = 20.96; 59.9% females) and Gaza (N = 676, age range 19-103 years, mean age M = 52.79, DT = 21.02; 47.8% females). Individual change-related events were correlated to subjective, hedonic and eudaemonic well-being (PHI scale). In both Basque Country and Gaza samples reported more positive autobiographical memories than negative. Regarding the influence of life events on well-being, have a greater impact those lived the previous year in individualist and better standard of living society, like Basque Country. In collectivistic society where the living conditions are worse like Gaza, long term changes or turning points were strongly associated to well-being, probably because they implies more consequential changes in social roles and quality of life than in the Basque Country. Total positive events scores were related to subjective well-being, as well as to its hedonic and eudaemonic dimensions, stronger than negative events score. Results are discussed in light of evidence provided by different studies from the international project CEVI.
