Abstract
Procrastination is said to be an extremely prevalent and pernicious form of self-regulatory failure. The descriptive-correlational study aimed to determine the causes, mechanisms, consequences, and the correlation between procrastination and mental health among the senior high school students of Mahayag National High School. The 280 respondents were chosen through complete enumeration. The first questionnaire measures one's procrastinating tendency, while the second measures one's mental health. The researcher underwent the Research Ethics Committee review procedures to ensure that the "do no harm" policy was duly observed and proper permission and consent were secured. The results revealed that the respondents have a moderate level of procrastinating tendency. They tend to procrastinate but not the extreme and not in a customary manner. Regarding their mental health, mental health's positive affect cupped a good result while the negative affect yielded a fair result. The researcher concluded that the respondents' most common procrastinating tendency is the ningas cogon or maňana habit, running out of time and doing things intended to do days before. It is done in academic and household settings, manifested through watching television, going through social media accounts, and sleeping resulting in educational, psychological, and physiological consequences.
