New Delhi: A deadline is approaching, an assignment remains unfinished, and a student opens a laptop only to check a phone, promise to start in five minutes, and lose an hour. For millions of college students, this familiar cycle may be causing more damage than they realize.

A study of 65,950 students across 97 higher education institutions in the United States has found that procrastination was the most common problem reported by students and the issue most frequently linked to poorer academic performance. Published in PLOS One on October 7, 2026, the research compared procrastination with 35 other life and health challenges, including financial difficulties, anxiety, depression, attention deficit hyperactivity disorder, and sleep problems.

The findings indicate that procrastination is widespread. Nearly three-quarters, or 72.3 percent, of students reported experiencing procrastination over the previous 12 months, placing it almost level with stress, which was reported by 73.8 percent. Furthermore, 45.4 percent of all students stated that procrastination had negatively affected their academic performance, a figure that climbed to 62.7 percent among those who specifically experienced it.

This academic impact was significantly higher than that reported for financial problems, which affected 16.1 percent of the overall sample, or ADHD, which impacted 12.9 percent. Researchers noted this does not imply procrastination is clinically more serious than a condition like ADHD for an individual, but rather demonstrates how widely delayed action interferes with academic work across a broad student population.

Undergraduate students reported greater difficulties with procrastination compared to those pursuing graduate and professional degrees. Among undergraduates, 74.8 percent reported procrastination, and 49.3 percent said it harmed their academic performance. In contrast, 66.2 percent of graduate and professional students reported procrastination, with 35.1 percent noting a negative impact on their studies.

Procrastination was also associated with significant psychological distress. Overall, 45.7 percent of participants stated that it caused them substantial distress, making it the leading life-related issue on this particular measure.

While the study relies on self-reported survey responses and does not prove direct causation for every reported academic struggle, researchers highlighted a familiar behavioral cycle. Delaying an assignment can increase overall stress, disrupt sleep patterns, and make initiating the task even more difficult later on.

Experts suggest that educators can help students act earlier by encouraging them to break assignments down into smaller, manageable steps, reflect on their avoidance patterns, and build stronger self-regulation habits. Ultimately, understanding why repeated procrastination occurs may be just as vital as rushing to meet the next deadline.
