Procrastination is conceptualized as postponing some actions crucial to the timely completion of assignments (Lay, Schouwenbur, 1986) or to “voluntarily delay an intended course of action despite expecting to be worse off for the delay” (Steel, 2007, p. 66) become a widespread phenomenon that has been established as a stable trait. It is defined as a self-regulatory failure, representative of low conscientiousness, high impulsivity, and thought control problems. Despite this rise in recognition and importance, the exact nature of procrastination is still being debated. Social networking sites (SNSs) have rapidly expanded since their inception in the early 2000s. Now social networking sites (Facebook, VKontake, etc.) are the part of modern life, but they are also the cause of achievement (especially academic) decline. Self-regulation and procrastination are the characteristics that can be defined as personality factors in online social network use. There is some evidence of the negative role of procrastination as well as low self-regulation in academic achievements. At the same time relations between procrastination and self-regulation are still unclear. This study analyses procrastination and self-regulation as predictors of social networking sites (SNS) usage intensity and intrusion. The sample consists of 329 users of Russian SNS VKontakte, from 17 to 60 ages. SNS usage assessed by SNS Intensity scale and SNS Intrusion scale. The features of procrastination and self-regulation (emotion regulation and activity regulation) were measured. SNS Intensity negatively associated with Self-regulation Expressive suppression, and Cognitive reappraisal, and has no associations with the Procrastination. SNS Intrusion positively associated with Procrastination and negatively with Self-regulation. The lack of Self-regulation predicts the intensity and intrusion of social network sites usage. Procrastination predicts only the intrusion of SNS use. Women showed a higher tendency to the frequent use of SNS and feeling of negative emotions if not able to use SNS.
