Nocturnal enuresis (NE) has been associated with neurodevelopmental disorders such as autism spectrum disorder, attention deficit or hyperactivity disorder, and intellectual disability. This study aimed to assess parents’ perception of NE in children in the eastern region of Saudi Arabia. We conducted a cross-sectional study from May to August 2023, including parents aged ≥18 years living in the area. We administered an online questionnaire to assess parents’ knowledge and attitudes toward NE and its treatment. A total of 616 parents completed the questionnaire, 71.4% of which were women, 35% were aged between 25 and 35 years, 75% were married, 65% had a university degree, and 49% had three or more children. In total, 70% demonstrated a good overall knowledge about NE and its treatment, and nearly 60% had a positive attitude toward the condition. Univariate and multivariate ordinal logistic regression analyses revealed that female sex, a higher level of education, and having more than one child were associated with a higher score regarding attitude toward treatment. The level of education and the number of children were predictors of knowledge and a positive attitude toward NE in children.
