Métrica de la escala de actividad física para adultos con discapacidad física PASIPD-C

Abstract

Objective: To develop cross-cultural adaptation and estimation of scalar metric properties (appearance validity, reliability - internal consistency and validity of construction) of the Physical Activity Scale for Physical Disability (PASIPD), Bogota, 2016. Design: Methodology of non-experimental observational, descriptive-correlational research. Sample: 47 people with an average age of 32.3±11.5 years; 51.1% women vs. 48.9% of men, from Bogota, with chronic physical disability, attending sports leagues and foundations and voluntarily signed informed consent. Materials and methods: It was revised lexicon and writing of PASIPD scale items adapting them to Colombian context. The validation of appearance (facial validity) was done with an expert concept of three physiotherapists specializing in physical activity and disability, the coordinator of "Muévete Bogotá" with Magister in Physical activity and health and a professional in the condition of disability. It was piloted with 21 adults in disability status. Then, PASIPD-C was applied in leagues and physical activity promoting entities. Statistical analysis was performed with IBM-SPSS statistic 20.0. Results: We estimated a mean of metabolic expenditure of 42.4±25.1, from 0.6 to 104.8 MET / hour / day. The highest metabolic expenditure occurs in vigorous effort activities (10.2±10.3-MET/hour/day) vs. outdoor gardening (0.32±1.4 MET/hour/day) of low metabolic expenditure. In men, the expenditure was 32.4 MET/hour/day, significantly lower (F=8.3;p=0.006) than that of women (52.0%MET/hour/day). There were no significant differences (p> 0.05) in estimated metabolic expenditure between age groups (F=0.342;p=0.795), congenital vs. acquired disability (F=2.58;p=0.15), disability (F=2.702; p=0.058) and use of technical aids (F=0.095; p=0.910). Regarding reliability, Cronbach Alpha of 0.721, high internal consistency. Exploratory factorial analysis of main components with varimax rotation of Kaiser agglutinated four factors (Activity less vigor; Activity moderate / intense effort; Light household activity; Activity under stress / care of others). Sampling adequacy KMO=0.56; Bartlett's sphericity (p<0.001) and sedimentation variance explained 67.6%. Conclusion: The PASIPD-C scale was adapted to the Colombian context, maintaining levels of validity of appearance, internal consistency and validity of construct at levels that validate its ideal use in the Colombian population, although it requires more population research evidence.
