The purpose of this study was to research the effects of Internet use onsocial life of university students. The study specifically addressed the following researchquestions: 1.What are the university students opinions about the effects of Internet use on social life? 2.Is there a relationship between time used on Internet and social life?Students were first asked why and to what end they use Internet. Results in surveys indicatedthat they most use it for study and communication. With regards to the purposes of Internetuse, no significant difference was found between groups neither in pretest (F(1,58) = .22; p= .64)nor in posttest (F(1,58) = .01; p= .94). Variations in purposes of Internet use between groups werenot statistically different, either (F(1,57)= .02, p=0.89, η2= .00). However, despite statisticallyinsignificant differences, a decline was observed in rates of Internet use for communication instudents in control group (CG) while Internet use as a mean of communication for students intreatment group (TG) showed a high increase.Pretest scores did not show differences between participants departments and daily Internetusing time (F(1,58) = 2.278; p= .11; ̅ ̅ ) nor time allocated to social life (F(1,58) =4.00; p= .05; ̅ ̅ ). With regards to same variables, posttest did not revealsignificant differences between groups in terms of time devoted to social life (F(1,58) = 3.95; p=.06; ̅ ̅ ) while groups significantly differ regarding daily Internet using time(F(1,58) = 10.94; p= .00; ̅ ̅ ).As regards changes in groups concerning daily Internet using time and time allocated to sociallife, no significant difference and relationship was detected in terms of changes of time spent onsocial life (F(1,57)= 1.24, p=.27, η2= .021) while changes about daily Internet using time weresignificantly different between groups (F(1,57)= 8.33, p=.00, η2= .13).Keeping groups under control, relationship between Internet use time and time allocated tosocial life in participants was reinvestigated based on increased time in participants to do both.Pretest results did not show significant relationship between Internet use time and timeallocated to social life (r=.04, p=.77) while posttest scores revealed a significant but negativerelationship between these variables (r=-.47, p=.00).To the question how they spend their leisure time, a majority of participants (n=48) respondedthat they were meeting with family members/friends in their spare times while others declaredthat they were reading (n=5).Participants were also asked whether computers have dehumanizing and desocializing effectson society and individuals. Most of participants in both groups indicated in pretest that Internetuse dehumanize and desocialize (n=33) while this rate was seriously declined in posttest (n=14).As to this change in answers with relation to that in Internet use time, participants havingincreased time of Internet use were observed to change in posttest their positive answer aboutdesocializing effects of Internet and therefore a significant relationship was obtained between changes in Internet use time and change of mind regarding socializing effects of Internet (r=.36;p=.00).Although the participants reported an educational use of Internet at first, they also declared ause for communicative purposes. When examined closer, this means that the more participantsin TG increased Internet use time, the more they used Internet for communicative purposes.Another point which is important is that times spent for both Internet and social life weretogether increased. Despite significant difference with respect to Internet use time, timesdevoted to social life did not significantly differ between groups; this could be better explainedby recreational patterns of the participants. As to spare time activities, they reported meetingwith family members/friends. This response as considered with negative relationship betweenInternet using times and times allocated to social life causes to lead to contradicting conclusionsbut especially with the aid of qualitative data gathered during interviews, it is clearlyunderstood that participants differently interpreted concepts and accordingly gave differentanswers.The major reason for different results obtained both in the present or previous studies seems tobe related to the question ―what is socialization?‖ Many students defined socialization assharing between more than one individual at the same time and the same place. Negativerelationship and contradiction between variables were due to the fact that the participants didnot consider online communication with family members/friends as Internet use but ordinarytalking.This explanation seems to be supported by changes between Internet using times and bychanges of mind concerning socializing effects of Internet. Because participants, havingincreased time of Internet use regardless of group, changed their previous statements aboutInternet and socialization, indicating that Internet had rather socializing effects. Between thesechanges, a positive relationship was detected which was previously reported in Stepanikova,Nie, & He (2010).One other important conclusion is that some participants, especially those being poor atcommunicating, indicated that they preferred to have an online chat with somebody instead offace to face meeting. At this point, participants said that communicating by using texts madeeasier for them to control what they want to express. Accordingly, the present work found, asprevious studies (Bromberg, 1996; Robinson et al. 2000; Parks & Floyd, 1996; Winzelberg, 1997)did, a supportive feature of Internet for social life.In conclusion, despite a tendency to believe that Internet dehumanizes and
