    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.

    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.
