Relations of Anthropometric and Conative (Normal and Pathological) Dimensions of Volleyball Junior Players

The main objective of this transversal study was to examine the relation of morphological and conative characteristics normal and pathologic factors in volleyball junior players The data were collected on the sample of examinees N 126 aged 16 to 17 years from five volleyball clubs The applied measuring instruments consisted of 23 anthropometric measures 16 normal and 12 pathological conative variables Descriptive statistics Pearson s correlation coefficient and canonical correlation analysis were applied for data processing The results showed that among the set of anthropometric characteristics and set of normal conative dimensions with 51 of explained variance there is a statistically significant canonical correlation of high level Rc 77 p 05 whereas among the set of normal and pathological conative dimensions with the interpreted variability of 59 two significant correlations of average intensity Rc 73 p 01 and Rc 70 p 05 were defined Following relevant canonical factors were isolated I morphological ectomesomorfic factors longitudinal dimensionality of the skeleton and transversal dimensionality of the skeleton II normal conative factors extraversionintroversion and anxiety intelligence self-awareness courage a sharp temper and protension introspection and insighthonesty and III pathological conative factors performance of systems for regulating and monitoring the biological functions and automatic functions and editing of responses of defense and attack The structure of the relations between anthropometric characteristics and conative normal and pathological latent dimensions was presented for a probability level of 0 0

FACTORIAL STRUCTURE OF THE RELATIONSHIP BETWEEN AGGRESSIVENESS AND PERSONALITY DIMENSIONS IN JUNIOR KARATEKAS

The goal of this study was to identify the factorial structure and the relation of aggressiveness and basic personality dimensions, as well as metric characteristics (reliability) of the applied scales and subscales. The study was conducted on a sample (N = 287) consisting of both genders, aged between 14-16 years. The following measuring instruments were used:  Buss-Perry Aggression Questionnaire (AQ), Eysenck Personality Questionnaire (EPQ), and the Big Five Plus Two Inventory (BF+2). The applied scales and subscales point to a high reliability type of internal consistency (α > .70), which confirms the appropriate psychometric characteristics, as well as validity of instruments on the athletic population. Principal Component Analysis (PCA) was performed, and with Varimax rotation, three dimensions with latent values of more than one were extracted, and they explain 60,41% of total variance. Results have shown that in the structure of the first component, factors of the second order (Psychoticism and Social desirability from the EPQ, Aggressiveness and Negative Valence from BF+2) significantly contribute to aggressive reactions. The second isolated component is saturated by personality constructs from the EPQ and BF+2 models, which can be interpreted as intrusiveness and domination. The composition of the third component – uncontrollable physical aggression – is maximally burdened by negative correlations of the dimensions Psychoticism and Social desirability from the EPQ, Conscientiousness (in a negative direction) and Negative Valence from BF+2, as well as Physical aggression from the AQ, Aggressiveness from BF+2, and Rage from AQ. In this study, theoretical and practical implications required for operationalization of these findings are discussed.Key words: karate athletes, AQ, EPQ-R, BF+

PEER VIOLENCE AS PREDICTOR OF CYBERBULLYING AMONG ADOLESCENTS

The aim of this cross-sectional study was to examine individual, familial and peer variables as predictors of cyberbullying in early adolescence. The research included (N = 226) male students from Valjevo, aged 15.56  (SD = 0.68). The following measuring instruments were used: Socio-demographic Questionnaire, Violence Among School Children Questionnaire, Parent Behavior Questionnaire. The internal consistency of the questionnaire was examined using Cronbach’s alpha coefficient. The results of correlation analysis have shown minute and statistically significant correlation between the scores of applied variables. Hierarchical regression model has explained 36% of the variance of traditional peer violence and 10% of cyberbullying. All the examined variables have proven to be statistically significant predictors of traditional peer violence, but not cyberbullying. Seeing that the predictor variables of traditional peer violence partly explain cyberbullying, it is necessary to examine other potential determinants such as frequency of use of electronic media, electronic victimization and others, which would contribute to the prediction of the examined criterion. The applied questionnaires are of optimal use in everyday practice in Serbia and can provide relevant information in evaluating traditional peer violence and cyberbullying among preadolescents
