Testing of the Incontinence Impact Questionnaire (IIQ-7) With Men After Radical Prostatectomy
Bibliographic record
Abstract
In Brief Objective The objective of this study was to test the validity and reliability of the Incontinence Impact Questionnaire (IIQ-7), a 7-item self-report instrument designed to assess the impact of urinary incontinence (UI), in men. Subjects Fifty-eight men with incontinence after radical prostatectomy were the subjects of the study. Methods Content validity was assessed by a panel of experts. Construct and criterion validity were examined with 3 groups of men who had UI in a randomized controlled trial comparing pelvic muscle exercises with pelvic muscle exercises plus electrical stimulation. Internal consistency and stability coefficients for the IIQ-7 were determined. Results The content validity index was 0.88. Four items were below the designated content validity index level. A 2-factor analysis solution (factor I—impact on daily activities; factor II—emotional impact) explained 84.94% of the variance. No significant group differences were recorded on impact of UI (F = 0.37, P = .70), nor were any differences among subjects found over time (F = 0.90, P = .50). A positive relationship was found between grams of urine loss on a 24-hour pad test and IIQ-7 scores (r = 0.34, P = .003 to .51, P = .001). When the IIQ-7 score decreased, self-reported quality of life improved as measured by the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Version 2 (r = −0.57, P = .0001 to −.49, P = .001). A strong relationship was found between responses to the question “Does leakage affect your life?” and the IIQ-7 scores. Internal consistency ranged between 0.88 and 0.92. IIQ-7 scores were consistent when urine loss was stabilized between 16 and 24 weeks after entry into the study (r = 0.89, P = .0001). Conclusion The IIQ-7 is a reliable measure of the impact of UI; however, the scale requires additional testing regarding construct validity in men. (J WOCN 2000;27:304–12.) Psychometric characteristics of the IIQ-7 are evaluated using a group of men experiencing urinary continence following radical prostatectomy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
