Earthquakes are natural disasters that are very destructive and whose timing is unknown. These disasters can have a very negative effect on people's mental health, and their effects can last for many years. This study examined the psychometric properties of a scale to measure earthquake obsession. Data were collected from adults living in different provinces of Türkiye (N = 732), who completed the new scale, Doomscrolling Scale, Death Distress Scale, and Mental Well-Being Scale. The Earthquake Obsession Scale (EOS) had a two-factor structure, good internal consistency reliability, and convergent and discriminant validity. Correlational analysis revealed that earthquake obsession was positively associated with doomscrolling and death anxiety, and negatively associated with well-being. Mediation analysis indicated that doomscrolling and death distress mediated the relationship between earthquake obsession and well-being. The results emphasized the potential of earthquake obsession to affect daily life negatively and revealed its relationship with psychological variables.
