It is important to understand causes and consequences of procrastination that appear common among general and academic populations. Procrastination affects people in various domains of life such as academic, professional, social relationships, and finance management. A person with high procrastination may lose his/her work, drop out from school, or may endanger his/her marital life. Similarly, high procrastinators might increasingly experience psychological distress related to lack of sense of personal control, self-worth and lack of sense of self-perceived personal ability as deadlines approach. The purpose of this study is to present theoretical and conceptual frames of procrastination that are important variables of individual difference and are common in general and academic populations.
