RESUMEN
BACKGROUND: Early screening instruments for professionals are important to reduce the cost and time of diagnosing pediatric lower urinary tract dysfunction. This study aimed to translate, cross-culturally adapt, and validate pediatric lower urinary tract symptom scores. METHODS: This methodological study was conducted in 2019 in two phases: translation and cross-cultural adaptation, and content validation. In the first phase, we used translators, specialists, and 30 parents of children with voiding dysfunction. In the second phase, validation was performed by 11 pediatric urology specialists. FINDINGS: The instrument was translated and adapted to Brazilian Portuguese and presented an excellent level of verbal comprehension. Further, the instrument presented a good content validity index >0.8 for all items, except for the nomenclature and clarity of two items, as indicated by the Cronbach's alpha value of 0.75 for internal consistency. DISCUSSION: The final version showed semantic, idiomatic, experiential, and conceptual equivalence with the original instrument, indicating that it is adequate for other assessments of psychometric qualities. PRACTICE IMPLICATIONS: The translation and adaptation of an important instrument for diagnosing lower urinary tract dysfunction in children to other countries helps nurses identify the disease early and monitor the treatment.

INTRODUCTION: The use of instruments to assess symptoms of the lower urinary tract has increased mainly when it comes to pediatric urology. The search for a validated and reliable one for use in clinical practice should be a concern of the professionals involved in the care of these children. OBJECTIVE: The aim of this study was to analyze the assessment instruments for lower urinary tract dysfunction in children regarding: symptoms, characteristics and psychometric properties. STUDY DESIGN: PubMed and Latin American and Caribbean Literature in Health Sciences databases were searched. The PICO strategy was used to construct the research question and bibliographic search. Keywords included voiding disorders, LUTS, Child, Surveys and Questionnaires. RESULTS: Nine articles were identified. The construct observed by all instruments was bladder dysfunction and seven instruments also assessed bowel dysfunction. Thirty different events were addressed. In eight instruments the respondents are the parents. The age of the target population ranged from three to eighteen years and regarding the number of items, an average of 21.8 items was observed. Six instruments showed good results of reliability and four presented good results of accuracy. CONCLUSIONS: The instruments included a wide range of symptoms related to dysfunction. Only two reported all validation and reliability tests, however six instruments showed good reliability results, making them eligible for the cross-cultural adaptation and validation process for use in countries other than those of the instrument's origin.

OBJECTIVE: The aim of the current study was to perform the translation, cross-cultural adaptation and validation of the Underactive Bladder Questionnaire (UAB-q). METHODS: The study design included the Portuguese translation, cross-cultural adaptation and validation of the UAB-q in 90 patients from a urology outpatient clinic following international methodology. The psychometric properties tested were the validity, reliability, internal consistency and stability of the instrument. RESULTS: The content validity index at the item (I-CVI) and scale level (S-CVI) were above 0.80 and did not require changes. Regarding the reliability analysis, Cronbach's alpha was 0.79. The internal consistency and the base time stability (test-retest) had excellent indexes; all were above 0.90. CONCLUSIONS: These results indicate that the UAB-q is a valid, reproducible and reliable instrument for screening underactive bladders and is a potentially useful tool to guide health actions and improve the care of underactive patients.
