Using Mental Contrasting with Implementation Intentions (MCII) to Reduce Bedtime Procrastination

We administered an online self-regulation intervention, mental contrasting with implementation intentions (MCII) to help undergraduate students reduce their bedtime procrastination. Participants (N=381) learned MCII or a positive-thinking control exercise. MCII (compared to control) reduced the average minutes of bedtime procrastination per night and increased goal commitment, three weeks later.
