Background: Advanced age is associated with decline in life satisfaction and resilience because of multiple factors such as physical limitations, increased dependency on others, lack of financial resources, the most difficult events in life, the decrease of assistance from society, and feeling of weakness and hopelessness. While some elderly people can compensate for these changes, others can’t adequately self-regulate and manage them, which subsequently affects their life satisfaction and resilience. The present study aimed to assess the effect of mindfulness training program on life satisfaction and resilience among elderly people at Zagazig city. A quasi-experimental study was established at the geriatric social club at El-Qawmia in Zagazig City. A purposive sample of 60 elderly people. Four tools were used: Structured Interview Questionnaire composed of two sections (demographic characteristics and socio-economic level of the studied elderly people), The Kentucky Inventory of Mindfulness Skills, Satisfaction with Life Scale, and Resilience scale.
