Validation of instruments to measure factors that influence the diagnosis of lymphoblastic leukemia in children

Abstract

Introduction: Acute lymphoid leukemia (ALL) is the most frequent cancer in children. Worldwide, it is estimated that about 30% corresponds to all malignant neoplasms that occur in children and of these, more than 75% are ALL. For this reason, we saw the need to develop an instrument to measure factors that influence the diagnosis. Because a timely diagnosis contributes to improving the life rate of these patients. Objective: Validate instruments to measure the factors that influence the diagnosis of lymphoblastic leukemia in children. Methodology: This is a mixed, cross-sectional, exploratory study. Non-experimental descriptive design. To validate the quantitative instrument, a pilot sample was used with 15 parents or representatives of children diagnosed with acute lymphoblastic leukemia, selected and chosen in a probabilistic random manner. For the qualitative instrument, a single mother of a child diagnosed with leukemia was used, validated by the judgment of five experts, three experienced oncologists and 2 magistrate nurses with experience in childhood oncology and Cronbach's alpha. Results: After the review and validation of the quantitative and qualitative instruments by the 5 experts, the score obtained is a very reliable score of 94.9 for the quantitative instrument and a very reliable score of 96 points for the instrument. qualitative. The scores achieved provide security for structure and process, through Cronbach's Alpha Coefficient and content and construct validity. Conclusion: these instruments are validated by expert judgment as very reliable tools to obtain data required for scientific research.
