[The IPPS questionnaire in XXXX and controls. Psychometric validation].

@entity1 @entity3465
The translation into Spanish of the AUA/International Prostatic Symptom (AUA/ @entity3465 ) Score hadn't been validated in spanish. METHODS. AUA/ @entity3465 questionnaire was self administered by 103 consecutive @entity1 and by 24 healthy volunteers. An alternative formulation to question 4 (ALT-4) was added. RESULTS. 51 @entity1 (49%) and 17 controls (79%) completed al questions (Feasibility). Reliability was measured by: a) Crohnbach's alpha (0.68 and 0.70 with ALT-4) b) Kendall's coefficient of concordance (0.097, significance < 0.001) and c) retesting 17 @entity1 within 2 months. The relation of the AUA/ @entity3465 scores with quality of life (Construct validity) showed a Spearman's correlation coefficient of 0.57 (confidence = 0.0001), and 0.52/0.0004 with ALT-4. The relation with uroflowmetry (Concurrent empirical validity) was poor as shown in ROC curves. CONCLUSIONS. The Spanish version of the AUA/ @entity3465 questionnaire given in an easy format improves feasibility without alteration of reliability or validity. The relation of the AUA/ @entity3465 score with uroflowmetry is poor, although the questionnaire can be considered valid and reliable.
