Validação brasileira da escala de autopercepção de harter para crianças

Harters Self-perception Profile for Children (SPPC) is used to evaluate childrens self-worth. The objective of this study was to translate and verify the validity of the items, the confirmatory factorial analysis and the test-retest internal consistence of the Brazilian version of SPPC. The participants of this study were 7 professionals and 746 children (8 to 12 years old) who answered the instrument at two different moments. The results indicated that the Brazilian version contains clear and pertinent questions (CVCt > 0.70), shows satisfactory indices of the confirmatory factorial validity (χ2/gl = 4.33; Non-normed Fit Index = 0.958; Comparative Fit Index = 0.967 and Tucker and Lewiss Index of Fit = 0.962) as well as of internal consistence. Thus, the Brazilian version showed to be valid.

Análise da consistência interna e fatorial confirmatório do IMPRAFE-126 com praticantes de atividades físicas gaúchos

In this study, motivation is understood in the context of Self-determination theory. This study aims to verify the index of reliability and confirmatory factorial validity of the IMPRAFE-126. A sample of 1.377 gauchos’ practitioners of physical activities, both sexes with ages between 13 and 83 years old, was used. The results of Cronbach’s alpha index (.89 to .94) had been satisfactory. The adequacy to the six-dimension model was tested and the construct confirmatory validity for the general sample was assumed (χ 2 /gl=2,520; GFI=0,859; AGFI=0,854; RMSEA=0,065), as so as for both sexes (masculine: χ2/gl=3,905; GFI=0,885; AGFI=0,881; RMSEA=0,066; feminine: χ2/gl=4,337; GFI=0,840; AGFI=0,831; RMSEA=0,068). These results indicate the IMPRAFE-126 is a promising tool that can be used by sports psychologists or personal trainers particularly interested in evaluate motivation levels of athletes or general practitioners of physical activities. New studies of validation, reliability and norms can be particularly helpful supposing a near future release.

Motivação à prática regular de atividade física: um estudo exploratório

Regular practical motivation for physical activity: an exploratory study. Motivation in Self-Determination Theory (SDT) suggests that one may be motivated in different levels. In this study these differences are explored through comparisons of the motivation general levels, taking into account the “gender and age groups” variables. A sample of 635 participants from both gender and ages between 18 and 55 years old answered the Motivation to the Regular Practice of Physical and Sports Activity Inventory (IMPRAFE-126). Results point significant difference ( F (2, 632) = 7,214; p = 0,001) only when controlled the age group. Differences were interpreted as recommended by SDT and related to the states and tasks of the development.

Motivação à prática regular de atividades físicas e esportivas: um estudo comparativo entre estudantes com sobrepeso, obesos e eutróficos

O principal objetivo do presente estudo e comparar os niveis de motivacao a pratica regular de atividades fisicas de tres diferentes grupos de alunos das escolas de ensino fundamental e medio do municipio de Erechim/RS: Obesos, com sobrepeso, e eutroficos. Para tanto, alem das avaliacoes antropometricas - massa corporal e altura - foi aplicado o Inventario de motivacao a pratica regular de atividades fisicas e esportivas (IMPRAFE-54) ( BALBINOTTI; BARBOSA, 2006 ). Os resultados variaram consideravelmente em valores nominais e a principais dimensoes motivacionais foram as seguintes: Obesos (saude); sobrepeso (estetica; saude; prazer); eutroficos (saude, estetica, prazer). Na comparacao inter-grupo (obesos; sobrepeso; eutroficos), a dimensao Estetica se destacou na diferenca entre os grupos de sobrepesos e obesos. Espera-se que esses resultados possam contribuir para a pratica pedagogica da educacao fisica escolar.
