Objective Smartphone addiction is a public health problem increasing with the technologic developments. It particularly affects the university students negatively in terms of psychological, physical, academic achievement and social relations. This study aims to investigate the relation of eating attitudes between smartphone addiction and internet gaming disorder, also the relation of smartphone addiction with obesity.Methods This cross-sectional and prospective study is consisted of 358 volunteer university students. Socio-demographic data form, Short Form of Smartphone Addiction Scale (SF-SAS), Eating Attitude Test (EAT), and internet gaming disorder scale were administered to the participants.Results Mean age of the participants was 22.27±3.10 years and 59.8% (n=214) were female. In terms of the variables “body mass index, body weight, faculty of the student, economic status of the family, and the people they live with together” were significantly different from controls. Also “monthly mobile phone invoice, EAT score, SF-SAS scores” were statistically different. A significant difference was found among “body weight groups” in terms of both EAT score and SF-SAS. According to the linear regression model variables of “gender, smartphone addiction, and school year” were determined as the predictors for EAT.Conclusion Our current study has revealed the relation between smartphone addiction and eating attitudes, and obesity. Smartphone addiction may lead to an increase in body weight, by affecting eating attitudes. Therefore, the effect of eating behavior disorders in the emergence of the smartphone addiction should be considered. Multi-disciplinary solutions are required to prevent this addiction that may increase over time.

Objective This study aims to evaluate whether smartphone addiction (SA) is associated with social media use and alexithymia levels in university students.Methods A group of 935 students aged between 18 and 45 years (509 females and 426 males) was recruited from different universities in Istanbul. SAs, alexithymia and social media use were assessed using the Smartphone Addiction Scale Short Version (SAS-SV), Toronto Alexithymia Scale-20 (TAS-20), and ad-hoc questions regarding social media use.Results The mean age of participants was 21.89±3.27 years and 509 of participants were female (54.4%). 455 (48.6%) participants were placed in the “SA” and 198 (21.2%) in the “alexithymia” categories. The study found a high level of positive correlation (p

Objective This study aimed to evaluate the reliability and validity of the Turkish version of Cognitive Attentional Syndrome-1 (CAS-1) questionnaire. Methods 221 participants were included in the study who do not meet any psychiatric diagnosis. Participants were applied SCID I and II and filled CAS-1 scale, Meta-Cognitions Questionnaire-30 (MCQ-30), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Generalized Anxiety Disorder-7 (GAD-7) Scale, and Penn State Worry Questionnaire (PSWQ). Testing the reliability Cronbach’s al pha, item analysis and Item and total score correlation coefficients were applied. For testing structural validity, Confirmatory Factor Anal ysis was used, and for testing the content validity, the relationship between each item of CAS-1 and MCQ-30, BDI, BAI, GAD-7, PSWQ was examined. Results The correlation reliability coefficients were statistically significant except for using alcohol/drugs as a coping mechanism. Cron bach Alpha reliability coefficient of 16 items was 0.771 whereas, this ratio was 0.772 for the first eight items (CAS) and 0.685 for the last eight items (Metacognitive Beliefs) which showed that the internal consistency of CAS-1 was high. Structural and Content Validity of the scale was significant. Conclusion The Turkish version of the CAS-1 was a reliable and valid measure to evaluate CAS in a Turkish population.
