چکیده (انگلیسی):

Nowadays the Internet is used more and more. The use that becomes the most popular is social networking sites. The main aim of our two studies is to find an answer to the question of whether personality and positive orientation are linked to Internet and Facebook addiction. Two studies were conducted, verifying the effects of personality traits and positive orientation on these two kinds of addiction. Study 1 involved 631 participants and Study 2 involved 452. The Bergen Facebook Addiction Scale, the Internet Addiction Test, the Short Personality Scale, and the Positive Orientation Scale were used. Our results indicate that lower positive orientation, conscientiousness, emotional stability, and openness to experience are related to problematic use of both Internet and Facebook. What is more, extraversion and agreeableness are connected only with problematic Internet use.
