The Effect of a Mindfulness Practice and Dispositional Mindfulness on Affective Forecasting

ABSTRACTA field experiment was conducted to evaluate whether mindfulness produces higher affective forecasting accuracy. Participants were randomized into a mindfulness-task, control-task, or baseline condition and then forecasted their positive and negative affect upon completion of an exam and upon receiving the exam grade. They also predicted their exam score. Those in the mindfulness-task condition more accurately predicted positive and negative affect upon exam completion and more accurately predicted negative affect and exam performance upon receiving their actual exam grade. Dispositional mindfulness predicted more accuracy in forecasting negative affect upon exam completion. Results suggest that mindfulness produces higher affective forecasting accuracy, particularly for negative affect. However, evidence was more mixed when considering the dispositional mindfulness results and for positive affect.
