RT Journal Article T1 Adaptation and Validation of a Questionnaire to Evaluate Knowledge of the Low Phe Diet in PKU A1 Ramos Álvarez, Rodolfo A1 Kapp, Maili A1 Rodríguez Ruiz, María Mercedes A1 Fausor, Rocío A1 Bueno Delgado, María Amor A1 Ahring, Kirsten A1 Waisbren, Susan E. AB Phenylketonuria (PKU) is an autosomal recessive disorder of phenylalanine (Phe) metabolism, causing a build-up of Phe in the body. Treatment consists of a Phe-restricted diet for life and regular determination of blood Phe levels to monitor the intake of Phe. Despite the fact that diet is the cornerstone of treatment, there are no studies examining common knowledge about food items and whether they are allowed as part of the PKU diet. Improving parents’ and patients’ knowledge and competence about the diet enables them to make appropriate food choices. This study validates a food-knowledge questionnaire first developed in Spanish and modified for English speaking populations. The questionnaire potentially helps parents to prepare appropriate meals and healthcare providers to create individualized educational programs about PKU for children and adolescents with this disorder.
