Mindfulness and positive reappraisal are two techniques that can mutually enhance one another to promote well‐being. However, research testing the effectiveness of interventions combining mindfulness and reappraisal is lacking. The current pilot examined the effect of a combined mindful‐reappraisal intervention on daily affect in a 5‐day diary study with 106 university students. Participants were randomized to a mindful‐reappraisal intervention ( n ?=?36), a reappraisal‐only intervention ( n ?=?34), or an active control activity ( n ?=?36). All participants described a negative event each day but only reappraised the event in the intervention conditions. Using multilevel growth modelling, results indicated that negative affect in both interventions declined over 5?days compared to the control; however, there were no differences in the growth of positive affect. Compared to reappraisal‐only, the mindful‐reappraisal group reported overall lower daily negative affect and marginally higher daily positive affect over the 5‐day intervention. These findings suggest that brief daily practice combining mindfulness and positive reappraisal can be trained as a self‐regulatory resource to promote positive affect and buffer negative affect above and beyond reappraisal practice alone. 收起
