Nadmierne korzystanie z sieci społecznościowych

Abstract Social networking sites (SNS) have become an integral part of people's lives, especially the young. In Poland, the most popular SNS is Facebook – almost 14 million use it every day. Users might communicate by SNS with their friends, share photos and movies or participate in groups. There are many functions of SNS that make them attractive. SNS satisfy their users’ needs such as the need to connect or to self-present. However it is not easy to find one reason why people use SNS. Because of the popularity of this media, a new question arises: it is possible to become addicted to SNS? Scientist use terms such as: excessive use, problem use or even an addiction, but there are still no precise criteria that might be useful to identify this problem. One might find analyses of time spending on SNS and activities performed by users in scientific articles about excessive SNS use. SNS addictive tendency was usually measured by questionnaires based on some internet addiction scales. Future research in this area is needed because SNS are still a novelty and it is necessary to differentiate normal usage from the abnormal.
