The objective of the present study was to replicate previous studies by examining the potential connections between mindfulness as a trait, life satisfaction and time perspectives (TP) and to analyze if balanced time perspective (BTP) could act as a possible mediator between mindfulness and life satisfaction in students from the University of Girona (Catalonia, Spain). Data was collected from 341 Catalan university students aged 18–52 (77.1% women; mean age = 23.62) who completed Zimbardo Time Perspective Inventory (ZTPI), the Mindfulness Awareness Scale (MAAS) and the Satisfaction with Life Scale (SWLS) to assess their Temporal Perspective, Mindfulness as a trait and Life Satisfaction respectively. Balanced time perspective (BTP) was calculated using the deviation index of BTP (DBTP). Results showed significant relationships between the various temporal dimensions, life satisfaction, and mindfulness as a trait, being the most significant associations with balanced temporal perspective. On the other hand, results also suggested that BTP may act as a mediator between mindfulness as a psychological trait and life satisfaction, confirming previous studies conducted in different countries. In conclusion, findings could highlight the importance of regulating one’s attention in order to balance time perspectives, which in turn would translate into improved life satisfaction.
