Psychosometric properties of the Filipino version of the international consultation on incontinence questionnaire-male lower urinary tract symptoms and female lower urinary tract symptoms

ABSTRACT

OBJECTIVE: The purpose of this study was to translate the International Consultation on Incontinence Questionnaire-Male Lower Urinary Tract Symptoms (ICIQ-MLUTS) and Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) into Filipino and determine its psychosometric properties mainly feasibility, internal consistency (reliability), and stability (test-retest reliability).METHODS: This was an observational, non-interventionist study, which recruited 100 male and 100 female patients seeking consult at the Philippine General Hospital for lower urinary symptoms. The questionnaires were completed in a single visit with the exception of 20 patients who were asked to answer the questionnaire again after 2 weeks to evaluate test-retest reliability. The ICIQ-MLUTS Filipino questionnaire is a 14-item self-administered questionnaire while the ICIQ-FLUTS Filipino questionnaire is a 13-item self-administered questionnaire.RESULTS: There was an 81% completion rate for the ICIQ-MLUTS questionnaire and 100% completion rate for the ICIQ-FLUTS questionnaire. Reliability testing revealed Cronbach's alpha coefficient of 0.949 for the ICIQ-MLUTS and 0.956 for the ICIQ-FLUTS questionnaire while test-retest reliability showed intraclass coefficient values above 0.9 for individual items of both questionnaires.CONCLUSION: The Filipino versions of the ICIQ-MLUTS and ICIQ-FLUTS questionnaires show adequate feasibility, reliability and validity.
