INTRODUCTION:
The Brockport Physical Fitness Test Battery (BPFT) is an assessment tool designed for children and adolescents with intellectual disabilities (1), which has been used nationally (2) and internationally (3) to determine the level of physical fitness. The instrument lacks reliability values for the Spanish-speaking population, hindering the development of intervention programs with health benefits (4) and public policies aimed at promoting physical activity and exercise. This research aimed to determine the reliability of the Brockport Physical Fitness Test Battery in children and adolescents aged 10 to 17 years with intellectual disabilities.
METHODS:
An assessment of the BPFT was conducted, including tests for body fat percentage, the sum of triceps and calf skinfolds, grip strength, push-ups, modified sit-ups, trunk lift, backsaver sit-and-reach, shoulder stretch, and PACER, on 56 children and adolescents with intellectual disabilities, aged 10 to 17 years, belonging to 2 educational institutions in the city of Bogotá, Colombia. The assessment was carried out by 4 expert evaluators at 3 different times; internal consistency analysis was performed using Cronbachs Alpha coefficient, test-retest analysis established the Intraclass Correlation Coefficient (ICC) and Spearman coefficient, as well as intra-evaluator reproducibility. Lastly, Cohens Kappa coefficient and ICC were calculated for inter-evaluator reproducibility analysis.
RESULTS:
Acceptable levels of reliability were observed for the BPFT. Internal consistency obtained a Cronbachs Alpha >0.6 with the elimination of the PACER and modified sit-up items, ICC values >0.8, Spearman coefficient and ICC >0.9, and Cohens Kappa 1.0 corresponding to test-retest reliability, intra-evaluator reliability, and inter-evaluator reliability for each of the items composing the instrument.
CONCLUSION:
The BPFT is a reliable and reproducible instrument for children and adolescents with intellectual disabilities in Colombia. It is recommended to review the selection of the modified sit-up item due to the risk of injury and its contribution to the construct of physical fitness for health. Also, it was observed from this research that certain elements of the test do not contribute to the internal consistency of the instrument or to the construct of physical fitness for health in the population. Among them are the Modified Curl-up and the PACER, which have already been described by some authors as tests that have no validity or require familiarization by the participants.
