Reliability of Thai Version of the ICIQ-FLUTS LF, Validity of Thai Version of the ICIQ-FLUTS LF Questionnaire
Conditions
Brief summary
The investigators recruited participants, who were female with LUTS 50 participants for known group validity and 80 normal control females to evaluate for construct validity and test for reliability by statistical analysis.
Detailed description
50 females with LUTS will completed the ICIQ-FLUTS and IPSS and then again at 2 weeks apart to test for convergent validity and test-retest validity. The normal control group 80 women will completed ICIQ-FLUTS LF for test of construct validity.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| How well the ICIQ-FLUTS LF questionnaire in the Thai version can differentiate between females with LUTS and normal females, was assessed by the construction validity. | 10-12 months | Incontinence Questionnaire - Female Lower Urinary Tract Symptoms Long Form (ICIQ-FLUTS-LF) was divided into 6 subgroups of symptoms measurement, which were storage, voiding, incontinence, bladder pain, post micturition, and ability to stop voiding. The construct validity was determined by comparing the ICIQ-FLUTS LF scores of the target group with the ICIQ-FLUTS LF scores of the control group. The comparisons were performed using the Wilcoxon signed-rank test. |
| The correlation between items within a subscale of the ICIQ-FLUTS LF questionnaire assessed by internal consistency. | 10-12 months | The internal consistency (a parameter that verifies correlations between items within a subscale of the questionnaire) was assessed by using Cronbach's alpha coefficients. The assessment was done in each subscale of the questionnaire. If Cronbach's alpha coefficients were between 0.7 and 0.95, the instrument was considered to have good internal consistency. |
| The consistency of the repeated measurements by the Thai version of the ICIQ-FLUTS LF was assessed by the test-retest reliability. | 10-12 months | The test-retest reliability (a property of producing repeated measurements that are consistent) was verified by having the participants of the target group answer the questionnaire twice with an interval of 2 weeks between the evaluations. We calculated test-retest reliability by using weighted kappa (κ). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The correlation between the IPSS questionnaire and ICIQ-FLUTS LF questionnaire was assessed by convergent validity. | 10-12 months | The convergent validity (how closely a test is related to other tests that measure the same or similar constructs) was determined by comparing the ICIQ-FLUTS LF scores of the target group with a known validated questionnaire. In this study we used the International Prostate Symptom Score (IPSS) as the comparison test. The comparisons were performed using Pearson's correlation. |
