The present study aimed to design, develop, and validate a training package for treating student procrastination based on grounded theory. In the first phase, a qualitative grounded theory study was conducted to develop this intervention. The study population consisted of students enrolled at the Persian Gulf University in the academic year 2023–2024. In the quantitative phase of this study, a quasi- experimental pre- test- post- test control group design was employed. A multi- stage random sampling technique was used to select participants. The procrastination questionnaire was randomly distributed to 1000 students from the Persian Gulf University, stratified by faculty, major, and year of entry. The findings indicated that the procrastination treatment package was effective in reducing procrastination among students.
