Norwegian translation, and validation, of the Pelvic Floor Distress Inventory (PFDI-20) and the Pelvic Floor Impact Questionnaire (PFIQ-7).

INTRODUCTION AND HYPOTHESIS: The goal was to translate into Norwegian, and validate, short versions of the Pelvic Floor Distress Inventory (PFDI-20) and the Pelvic Floor Impact Questionnaire (PFIQ-7) using a sample of women with symptomatic pelvic organ prolapse and pelvic floor dysfunction. METHODS: Modified European Organization for Research and Treatment of Cancer Guidelines were used for translation and cultural adaptation. Of 212 eligible Norwegian women who consented to participate, 205 completed the questionnaires, of whom 50 were retested after 1 - 3 weeks, and 76 were tested 6 months after surgery. Reliability, validity and responsiveness were evaluated. Additionally, interpretability, the smallest detectable change, the standard error of measurement, floor and ceiling effects, and the percentages of missing items are reported. RESULTS: Reliability ranged from 0.66 to 0.93 and intraclass correlation coefficients from 0.85 to 0.94. Both construct validity and responsiveness were found to be adequate. The responsiveness of the PFDI-20 was further supported by areas under the curve above 0.70. Estimates were lower for the PFIQ-7. The smallest detectable changes at the individual level were 15 - 21 % and 17 - 27 % for the PFDI-20 and PFIQ-7, respectively. The absolute values of the minimal important changes in the total scores were 48 and 47, respectively. No floor or ceiling effects were evident in the distributions of the PFDI-20 and PFIQ-7 total scores. CONCLUSIONS: The translated questionnaires provided adequate reliability, validity and good responsiveness to change. These short versions of the PFDI and PFIQ are robust measuring instruments that will enable symptom severity and health-related quality of life to be evaluated in the Norwegian context.

Hysterectomy and incontinence: a study from the Swedish national register for gynecological surgery.

BACKGROUND: Hysterectomy is one factor that has been suggested to be a risk factor for developing stress incontinence. In Sweden, with a population of 8.86 million, a national register was set up in 1997 in order to have data for assessing the quality of gynecological surgery for benign disorders. METHODS: Data in the Swedish national register for gynecological surgery during the period 1997-2002 were investigated. Surgical methods compared during this time period were: total hysterectomy (abdominal/laparoscopic, n=198/116), subtotal hysterectomy (abdominal/laparoscopic, n=163/86), and total hysterectomy (vaginal/laparoscopic assisted vaginal, n=265/7). Patients who underwent endometrial destruction (endometrial ablation, endometrial balloon treatment, n=187) were used as a control group. Only patients with no preoperative complaints were included. Outcome measures were answers to subjective questions asked pre- and postoperatively regarding urinary problems and incontinence. RESULTS: De novo symptoms of stress incontinence, urgency and urgency incontinence, and/or mixed incontinence were noted in all groups. No differences were found among the groups. CONCLUSION: Factors other than hysterectomy should be discussed causing stress incontinence in women.
