SUMMARYThe basic goal of this research was to evaluate sociocultural influence of parents on general body dissatisfaction among their adolescent children. The sample comprised (N = 228) of both male and female adolescents aged between 16-19 years. In this study, two measuring instruments were applied: Body image and body change inventory and the Perceived Sociocultural Influences on Body Image and Body Change Questionnaire. These instruments show internal consistency of high reliability, which makes them applicable to the Serbian population. According to results of the correlational analysis, there is a mild correlation between predictor variables (influence of mother and influence of father) and the criteria general body dissatisfaction. The applied hierarchical regression analysis showed that predictor variables explain 22% of the total variance of general body dissatisfaction. It was also established that variables (female gender, sociocultural influence of parents on body image and change in physical appearance) present significant predictors of overall body dissatisfaction in late adolescence. The majority of the obtained findings is in accordance with results from previous studies, and should provide directions for predicting body image and perceptive sociocultural contributions on body image, as well as designing programs of prevention regarding body dissatisfaction in adolescents of both genders.
The aim of this research was to examine the contribution of body mass index (BMI), motor skills and physical self-concept in explaining the physical activity (PA) of adolescent karatekas (N=148). The average age of participants was 16,56 years (± 1,14). The following measuring instruments were used: Body Mass Index (BMI), Eurofit Physical Fitness Test Battery, Physical Self-Description Questionnaire (PSDQ), and Physical Activity Questionnaire for Adolescents (PAQ-A). The Cronbach's alpha coefficient was used to determine the internal consistency of the questionnaires. The results of the hierarchical analysis showed that the predictor variables explained 18,5% of the total variance of the criterion PA of junior karatekas. With their positive direction, the independent variables of the physical self-concept strength (β = 0.049; p < 0.01), flexibility (β = 0.037; p < 0.01) and self-respect (β = 0.019; p< 0.05) showed the maximum statistically significant contribution to predicting the variability of the participants' PA, which means that junior karatekas who manifest the higher level of perception on those variables exhibit the higher level of PA. This study confirmed that the applied instruments are valid and suitable to predict PA among adolescent athletes in Serbia.
SummaryIntroduction. The aim of the study was to examine the contribution of personal traits and social variables to the prediction of the frequency of cigarette and alcohol use in adolescents.
Cilj ovog istraživanja bio je da se ispitaju parcijalni doprinosi individualnih karakteristika odbojkaša oba pola i emocionalne atmosfere u porodici u tumačenju konstrukta emocionalne regulacije. U istraživanju učestvovalo je 286 ispitanika (142 kadeta i 144 kadetkinja), uzrasta od 16 do 17 godina. Primenjeni su merni instrumenti (Upitnik emocionalne regulacije i kontrole, Skala percepcije roditeljskog ponašanja, Skala dečje percepcije sukoba među roditeljima, Upitnik temperamenta u ranoj adolescenciji i Skala pubertetskog razvoja). Dobijeni rezultati pokazali su da su individualne karakteristike i dimenzije temperamenta odbojkaša i odbojkašica značajne determinante njihove emocionalne regulacije. Adolescenti koji su imali intenzivniju samokontrolu minimalno su ispoljavali negativne emocije i uspešnije kontrolisali svoja osećanja. Dimenzije roditeljskog ponašanja, značajno su uticale na tumačenje konstrukta emocionalne regulacije isključivo kod kadeta. Odbojkaši koji su percipirali viši nivo prediktorskih varijabli majčine kontrole i očevog odbacivanja, lošije su upravljali sopstvenim emocijama.
This paper provides a concise overview and analysis of research that shows the results of teachers' difficulties in using digital technologies in teaching. The aim of the work is to identify specific research problems, how they have transformed over time, what methodology was applied in those researches and what empirical knowledge was obtained. The analysis of the results showed that different methodological solutions are used in the research, and that there are different problems of teachers, the most dominant of which is information about digital technologies and the function that teachers manifest in the process of their application in teaching. In the concluding discussion of the work, research is listed that can contribute to the understanding of the authentic difficulties of teachers in the application of digital technologies in teaching and the development of a context that would enable teachers to effectively solve these concerns.
