Investigating the Construct Validity and Reliability of the Test of Motor Competence Across Iranians’ Lifespan (original) (raw)

Assessment of Motor Competence Across the Life Span

SAGE Open, 2016

In this article, the psychometric properties of a new test battery aimed at quantifying motor competence across the life span are explored. The battery was designed to be quantitative, simple to administer, applicable for large-group testing, and reliably to monitor life span motor development. A total of 638 participants between 5 and 83 years of age completed assessment of four different motor tasks (two fine and two gross motor tasks), enabling us to investigate its feasibility, internal consistency, construct validity, and test–retest reliability. Feasibility: Overall pattern of results suggest that the test battery for motor competence presented here is applicable for the age-span studied (5-83). Important consideration in this regard is that the same tasks are applied for all ages. A u-shaped curve between age and total test score indicate the adequate sensitivity of the test battery for the age range examined. Internal consistency: All individual test item scores correlated p...

The General Motor Ability Hypothesis: An Old Idea Revisited

Perceptual and motor skills, 2018

While specific motor abilities have become a popular explanation for motor performance, the older, alternate notion of a general motor ability should be revisited. Current theories lack consensus, and most motor assessment tools continue to derive a single composite score to represent motor capacity. In addition, results from elegant statistical procedures such as higher order factor analyses, cluster analyses, and Item Response Theory support a more global motor ability. We propose a contemporary model of general motor ability as a unidimensional construct that is emergent and fluid over an individual's lifespan, influenced by both biological and environmental factors. In this article, we address the implications of this model for theory, practice, assessment, and research. Based on our hypothesis and Item Response Theory, our Lifespan Motor Ability Scale can identify motor assessment tasks that are relevant and important across varied phases of lifespan development.

Evidências de validade de construto, critério e fidedignidade da Motor Competence Assessment em pré-escolares

Journal of Physical Education

A literatura tem evidenciado a necessidade de estudos de validação de testes motores para avaliação da competência motora (CM). Assim, Luz e colaboradores propuseram uma bateria de testes Motor Competence Assessment (MCA) para avaliação da CM em crianças e adolescentes portugueses. Objetivou-se investigar as evidências de validade da MCA em uma amostra de pré-escolares brasileiros e testar a correlação entre resultados da CM avaliados com a MCA e o Test of Gross Motor Development -2 (TGMD-2). Participaram 251 pré-escolares de ambos os sexos, de seis Centros de Referência em Educação Infantil de João Pessoa-PB. Os dados foram coletados por meio da MCA e do TGMD-2. Os resultados da análise fatorial confirmatória (AFC) mostraram dois modelos, um com índices de ajuste adequados; Os coeficientes de correlação interclasse variaram entre 0,77 e 0,96, indicando confiabilidade excelente; a correlação entre a MCA e o TGMD-2 foi significante com magnitude moderada (r = 0,57, p<0,01). A es...

Psychometric Properties of the Test of Gross Motor Development, Third Edition (German Translation): Results of a Pilot Study

Journal of Motor Learning and Development, 2017

The Test of Gross Motor Development, 3rd Edition (TGMD-3) is a process-oriented fundamental movement skill assessment to examine the movement patterns displayed by children between the ages of 3 and 10 years. Within this paper, results of a pilot study on the reliability, validity, and measurement invariance across gender of the TGMD-3 (German translation) are presented. In total, performances of 189 typically developing children (99 boys, 90 girls, 56 kindergarten children, 133 elementary school children, Mage = 7.15 ± 2.02 years) are analyzed. Results provide preliminary evidence for test-retest, interrater and intrarater reliability, internal consistency, age- and gender- specific performance trends, factorial validity, measurement invariance across gender, divergent validity, and ball skill–related concurrent and predictive validity of the TGMD-3 (German translation). Subsequent research should be focused on a verification of the present findings on a representative database to ...
