Resumen

Objectives: To validate a scale to assess contamination of food at home and measure the validity and reliability. Methods: mothers or caregivers with children under 5 years were surveyed in San Juan de Lurigancho in Lima Peru. The scale was previously subject to a rating of expert judges. Factor analysis with principal components was performed; the internal consistency was measured with Kuder-Richardson Formula 20 (KR-20) and the validity of the test with the coefficient Kaiser-Meyer-Olkin (KMO) and the sphericity test Barlet. Results: The sample was 194 caregivers. Three components (Practices cleaning, storage practices and pollution of the child) with a total of 10 items were identified. The item Cleaning Practices had a KR-20 = 0.722 storage practices and food contamination 0.518 and 0.5 respectively. The validity of the test was KMO = 0.549 and 591,678. Barlet test, df = 136, (p
