Öğe The Psychological Characteristics and Health Related Behavior of Adolescents: The Possible Roles of Social Physique Anxiety and Gender(Cambridge Univ Press, 2010) Çağlar, Emine; Bilgili, Naile; Karaca, Ayda; Ayaz, Sultan; Aşçı, F. HülyaThe purpose of this study was to examine whether or not the social physique anxiety level and gender have an influence on psychological characteristics and health related behavior of adolescents. Five hundred and ninety eight female (M-age = 14.95, SD = .70 years) and three hundred and eighty four male (M-age = 15.08, SD = .76 years) adolescents voluntarily participated in this study. The Social Physique Anxiety Scale (SPAS), three subscales of the Physical Self-Description Questionnaire, and the Multidimensional Perfectionism Scale as indicators of psychological characteristics were administered to all participants. The Eating Attitude Test and Physical Activity Assessment Questionnaire were used to determine health related behavior. It was found that adolescents with high levels of SPA (HSPA) had more unfavourable eating attitudes, higher scores in socially-prescribed perfectionism, negative global physical self-worth and negative body related perceptions than those with low levels of SPA (LSPA). Physical activity levels of adolescents did not differ in the two SPA groups (high/low level). In addition, male adolescents in the present study were more physically active and had favorable eating attitudes and more positive self-perceptions of body fat and general physical self-worth than their female counterparts.Öğe Screen Time Differences among Turkish University Students as an Indicator of Sedentary Lifestyle and Inactivity(Fac Teacher Education, 2017) Caglar, Emine; Bilgili, Naile; Karaca, Ayda; Deliceoglu, GokhanThe aim of the present study was to examine the screen time differences as an indicator of sedentary lifestyle in terms of some socio-demographic variables among university students. A total of 2209 university student (M-age = 20.80, SD = 1.61 years) participated in this study. The demographic information and screen time data were collected by using a survey form. The screen time refers to the combined time spent on watching TV/video, watching/playing/working on a computer, and playing video games. Two x three factorial ANOVA revealed significant gender and socioeconomic status differences in the screen time. The male students and those with a high socio-economic status had higher screen time. In addition, one-way ANOVA showed significant screen time differences in terms of parental education level and place of residence (p < .001). The students living in dormitories and those whose parents had lower education level had lower screen time. Also, the students who had an opportunity to access technological devices in their place of residence and in their bedrooms had higher screen time than the students who did not have these facilities (p<.001). The screen time as a sedentary behavior among university students is quite high and these findings can be taken into account as a warning indicating increases in the sedentary lifestyle of these young adults.Öğe Screen time of adolescents in an economically developing country: The case of Turkey(Taylor & Francis Ltd, 2011) Karaca, Ayda; Caglar, Emine; Bilgili, Naile; Ayaz, SultanBackground: Most studies of screen time of adolescents have been carried out in well-developed countries. There is little information concerning screen time of adolescents in developing countries such as Turkey. Aim: This study examined the screen time of adolescents with regard to gender, school type and sport participation in Turkey, selected as an example of an economically developing country. Subjects and methods: A total of 916 high school students participated in this study. The household activities and sport indexes of the Physical Activity Assessment Questionnaire were administered to the participants. Results: Male students had higher screen time (hours/day) than female students and the screen time of the adolescents was longer at the weekends than on weekdays (p < 0.01). The students attending private schools spent more screen time on both weekdays and weekends than those attending public schools (p < 0.01). The results did not reveal significant screen time differences with regard to participation duration in sport activities (p > 0.05). Conclusions: Male adolescents and students attending private schools had a higher screen time rate than their counterparts, both on weekdays and at the weekend. Participating in sport for different durations did not make any difference to the screen time of these adolescents.Öğe Validity and reliability of the Very Short form of the Physical Self-Inventory among Turkish adolescents(Taylor & Francis Ltd, 2017) Asci, F. Hulya; Maiano, Christophe; Morin, Alexandre J. S.; Caglar, Emine; Bilgili, NaileThe study aimed to test the validity and reliability of the Very Short form of the Physical Self-Inventory (PSI-VS) among a sample of 635 Turkish adolescents. These adolescents have completed the 12 original items of the PSI-VS, plus a positively worded reformulation of the single reverse-keyed item of the physical attractiveness subscale. A series of confirmatory factor analyses was used to examine the psychometric properties of the original and modified versions of the PSI-VS. Findings revealed superior psychometric properties with the modified version than with the original set of items. The modified version was thus subsequently used to examine its factor structure invariance across sexes, age groups and sport practice involvement. Results not only report that this version was fully invariant across, but also that latent means were significantly different across sexes and sport practice involvement. In sum, the Turkish modified version of the PSI-VS presents acceptable psychometric properties and may be used to repeatedly and/or intensively assess participants' physical self-perceptions in the context of sport and exercise interventions.
