This research aimed to develop, validate, and test a questionnaire that university undergraduate students can use to gauge their self-regulation skills (SRS). The researchers developed the questionnaire's items through a review of related literature and then validated them with a panel of specialists, i.e., PhDs. The questionnaire's validity was checked using EFA and quantitative methods. One hundred university students aged seventeen to twenty became part of the study's sample. At first, a 66-item questionnaire was developed using a thematic analysis of the qualitative part. An expert panel verified that the questionnaire was valid regarding its substance. After eliminating duplicates and irrelevant questions, a final questionnaire consisting of 27 items was developed. The four basic constructs of self regulation skills are behavioral regulation, cognitive regulation, emotional regulation, and self-compassion. Researchers employed the tool to gauge university students' ability to self-regulate through four self-regulatory skills constructs.
