Item type:Publication, Psychometric Properties of the Physical Self-Concept Questionnaire in Peruvian Adolescents(Federacion Espanola de Docentes de Educacion Fisica, 2023-01-01)Physical self-concept is an important health marker, since it predicts -mainly in adolescence- psychological health problems such as image anxiety, eating disorders, low self-esteem, dissatisfaction with life, among others. In this sense, having a physical self-concept measurement instrument with evidence of validity and reliability for a particular context is essential for the work of physical education, medical or related professionals. The aim of the study was to analyze the psychometric properties of the physical self-concept questionnaire (CAF) in Peruvian adolescents. This was a descriptive cross-sectional study in which 1314 schoolchildren (15.59±1.05) from Lima and Callao (54.5 % males and 45.5 % females) participated. The results of the confirmatory factor analysis (CFA) of the structure of the original questionnaire showed inadequate fit indices, so the model had to be re-specified and a new structure proposed. After the respecification, a model of 22 items with the same number of factors (five) was found, a model that presented adequate adjustment indexes (2/gl=4.38, RMSEA= .05, SRMR= .05, GFI= .94, CFI= .92, TLI= .91). Regarding reliability, an adequate internal consistency was reported for the complete questionnaire (.86). In conclusion, the 22-item CAF model shows validity and reliability for adolescents in the Peruvian context. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Psychometric Properties of the Peruvian Version of the Gross Motor Development Test - Third Edition(Federacion Espanola de Docentes de Educacion Fisica, 2023-01-01)The Test of Gross Motor Development - Third Edition (TGMD-3) assesses the fundamental motor skills competence of children aged 3 to 10 years. The objectives of the study were to translate the TGMD-3 into Peruvian Spanish and to analyze its psychometric properties for Peruvian children aged 6 to 10 years. A cross-cultural translation of the TGMD-3 was carried out in order to have a Peruvian Spanish version. The study involved 19 professionals and 348 Peruvian children aged 6 to 10 years recruited from the three natural regions of Peru (coast, highlands and jungle). Item rating agreement among experts was appropriate (Content Validity Index > 94.4 %; Kappa Coefficient > .802). The confirmatory factor analysis corroborated the validity of the two-factor model (chi-square on degrees of freedom = 1.618; comparative fit index = .905; root mean square error of approximation = .042; standardized root mean residual = .056; goodness-of-fit index = .998), showing acceptable construct validity. Concurrent validity ratified the motor deficits or potentialities presented by the children (-.68, p < .001). Finally, the reliability indices obtained (internal consistency = .851, test-retest = .951, inter-rater = .963, intra-rater = .983) met the most demanding standards. The results confirmed that the TGMD-3 Peruvian version is appropriate for assessing the fundamental motor skills competence of Peruvian children. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Attitudes and Physical Self-Concept as Determinants of Physical Activity Practice(Universidad de Murcia Servicio de Publicaciones, 2023-01-01)The regular practice of physical activity (PA) in adolescence is essential for good health throughout life; therefore, studying the variables that condition PA behavior is of great importance to reinforce or modify behavior in a timely manner in order to guarantee a healthier society. In this sense, the main objective of this study was to examine the correlation and relationship between attitudes and physical self-concept with PA practice in Peruvian adolescents. This is an empirical research of an associative nature in which 1264 schoolchildren aged between 14 and 17 years (15.51±.94), from public and private institutions in Lima and Callao, Peru, participated in a sociodemographic questionnaire, a questionnaire of attitudes towards the practice of physical-sports activity, a physical self-concept questionnaire and an inventory of habitual physical activity. The results, firstly, showed that the highest correlation score between the variables studied was between attitudes and PA practice (.511), which was corroborated by a large effect size (.25). Second, 25.1 % of the variability in practice was found to be due to changes in attitudes and physical self-concept. In addition, according to the multiple regression analysis, the model proposed proved to be valid (y = -.560 +.894x1+0.94x2). Thus, on the one hand, it is explained that for each point that is increased in attitudes (x1), PA practice increases.894 on average, keeping physical self-concept constant (x2); on the other hand, for each point that is increased in physical self-concept (x2), PA practice increases.94 on average, keeping attitudes constant (x1). In conclusion, it is shown that the attitudes and/or physical self-concept of adolescents condition PA practice.
