Abstract

OBJECTIVES: To evaluate the psychometric properties of the Spanish version of the ICIQ-Male Lower Urinary Tract Symptoms Questionnaire (ICIQ-MLUTS): Feasibility (% of completion and ceiling/ground effects), reliability (Test-retest), convergent validity (vs Bladder Control Self-Assessment Questionnaire [BSAQ] and vs International Prostate Symptom Score [I-PSS]) and criterion validity (according to presence or absence of symptoms).

MATERIAL AND METHODS: This was an observational, non-interventionist and multicenter study. 223 male patients with lower urinary tract symptoms (LUTS), predominantly storage symptoms and aged 18-65, took part in the study. Patients completed the ICIQ-MLUTS (test), I-PSS and BSAQ questionnaires and referred their urinary symptoms in a single visit, with the exception of a subgroup composed by 49 patients that completed the questionnaire again 15 days after initial visit to evaluate test-retest reliability. The questionnaire includes 13 items divided in 2 sub-scales: Voiding symptoms (V) from 0-20 and Incontinence symptoms (I) from 0-24.

RESULTS: Percentage of patients that completed all items: 98.84%. Ground effect is 0 and ceiling effect was under 6% in both sub-scales. Test-retest reliability: Intraclass correlation coefficient (ICC) ranged from 0.68 to 0.88, except on Delay. Kappa shows a good agreement, between 0.60 and 0.81, except for Nocturia. Convergent validity: Correlation (Spearman) between the questionnaire sub-scales scores and the rest of measures is statistically significant (P < .01 and P < .05). Criterion validity: Statistically significant differences (P < .05) between scores on ICIQ-MLUTS, from patients that refer experiencing symptoms and those who do not.

CONCLUSION: The Spanish version of the ICIQ-MLUTS questionnaire shows adequate feasibility, reliability and validity.
