Summary
The Spanish AUA/IPS questionnaire is a valid and reliable tool for assessing prostate symptoms, showing improved feasibility with an easy format. Its correlation with uroflowmetry was poor, but it remains a dependable patient self-assessment method.
Area of Science:
- Urology
- Medical Informatics
Context:
- The International Prostate Symptom Score (IPSS) is widely used but lacks Spanish validation.
- Prostate symptom assessment is crucial for patient management and treatment efficacy.
Purpose:
- To validate the Spanish translation of the AUA/International Prostatic Symptom (AUA/IPS) Score.
- To assess the feasibility, reliability, and validity of the Spanish AUA/IPS questionnaire, including an alternative formulation for question 4 (ALT-4).
Summary:
- A Spanish version of the AUA/IPS questionnaire was administered to 103 patients and 24 healthy volunteers.
- Feasibility was high, with reliability confirmed by Cronbach's alpha and retesting.
- Construct validity (correlation with quality of life) was good (Spearman's rho = 0.57), but concurrent empirical validity with uroflowmetry was poor.
Impact:
- The Spanish AUA/IPS questionnaire demonstrates good feasibility, reliability, and validity for patient self-assessment of prostate symptoms.
- The study highlights the importance of culturally validated instruments in clinical practice.
- While not correlating well with uroflowmetry, the questionnaire remains a valuable tool for clinical use.
