Procrastination Tops the List of Study Problems in a Large U.S. Survey

1Procrastination was the issue that U.S. college students most often said had hurt their studies, a new study has found. It was also nearly tied with stress as the most common problem.

2Itamar Shatz, a researcher at the University of Cambridge, analyzed survey answers from 65,950 students at 97 U.S. colleges and universities. The students took the survey in spring 2025. They were asked about a list of 36 issues they might have faced over the previous year. The list ranged from money problems to anxiety and ADHD. Shatz published his findings in the journal PLOS ONE on October 7.

3Overall, 72.3 percent of the students said procrastination had been a problem for them, compared with 73.8 percent for stress. When asked which issues had harmed their schoolwork, 45.4 percent chose procrastination. That was the highest share for any of the 36 issues. It was about 2.8 times the share for money problems and about 3.5 times the share for ADHD.

4ADHD came first, however, when the analysis looked only at students who had each issue. Of the students with ADHD, 64.1 percent said it hurt their studies, compared with 62.7 percent of those who had trouble with procrastination. Procrastination was also more common among undergraduates, at 74.8 percent, than among graduate students, at 66.2 percent.

5The survey has limits. Students judged for themselves whether an issue had hurt their work, so the results show links rather than proof of cause. The paper also says anxiety or poor sleep could lead to procrastination or make it worse. In addition, the students in the sample do not represent all U.S. college students.

6According to Times Higher Education, Shatz said poor time management is a symptom, not the cause, of procrastination. He suggested that universities help students divide large assignments into smaller steps. He also suggested more frequent deadlines for smaller pieces of work, since deadlines motivate procrastinators.

全文訳

1アメリカの大学生が「勉強に悪い影響が出た」といちばん多くあげた悩みは先延ばしだったことが、新しい研究でわかりました。また、いちばん多い悩みとしても、ストレスとほぼ並びました。

2ケンブリッジ大学の研究者イタマール・シャッツさんが、アメリカの97の大学などの学生65,950人の調査の回答を分析しました。学生たちは2025年の春にこの調査に答えました。それまでの1年間にぶつかったかもしれない36の悩みについてたずねられました。リストには、お金の問題から不安やADHDまでがふくまれていました。シャッツさんは10月7日、この結果を学術誌 PLOS ONE に発表しました。

3全体では、学生の72.3％が先延ばしに困ったと答え、ストレスは73.8％でした。どの悩みが勉強に悪い影響をあたえたかを聞かれると、45.4％が先延ばしを選びました。これは36の悩みの中でいちばん高い割合でした。お金の問題の約2.8倍、ADHDの約3.5倍にあたります。

4ただし、それぞれの悩みを持つ学生だけにしぼって見ると、1位はADHDでした。ADHDのある学生の64.1％が勉強に悪い影響が出たと答え、先延ばしに困った学生では62.7％でした。また、先延ばしは大学院生（66.2％）より学部生（74.8％）に多く見られました。

5この調査には限界もあります。悩みが勉強に悪い影響をあたえたかどうかは学生が自分で判断したので、結果からわかるのは関係であって、原因の証明ではありません。論文は、不安や睡眠不足が先延ばしを引き起こしたり、ひどくしたりする可能性もあるとしています。さらに、調査に答えた学生は、アメリカの大学生全体を代表しているわけではありません。

6タイムズ・ハイヤー・エデュケーションによると、シャッツさんは、時間の使い方がうまくないのは先延ばしの原因ではなく、その表れだと述べました。シャッツさんは、大学が学生を手助けして、大きな課題を小さなステップに分けさせることを提案しました。さらに、締め切りは先延ばししがちな人のやる気を引き出すので、小さな作業ごとに締め切りを増やすことも提案しました。

文法ポイント：接続詞のあとの「主語 + be動詞」の省略（When asked ～）

when や if のあとで、省いた主語が文の流れからわかるとき「主語 + be動詞」を省くことがある。本文の When asked which issues had harmed their schoolwork は When they were asked ～ の they were を省いた形で、「～とたずねられると」という意味。
