Construction and validation of a short‐form benign prostatic hypertrophy health‐related quality‐of‐life questionnaire

Abstract

Objective To construct and validate a short-form benign sexual-life status, and BPH interference with activities. The QOL9 was practical in use (completion rate prostatic hypertrophy (BPH) health-related quality-oflife (HRQL) questionnaire which is more practical in 87-100%; duration of completion at inclusion 11.6, sd 2.0 min), consistent (Cronbach's alpha>0.7), use and as informative as the 20-item visual analogue scale questionnaire (QOL20) previously validated in reliable (intraclass correlation coeÃcient >0.80) and responsive (eÂect-size index 0.9, sd 0.01 in the longiFrench. Patients and methods From the factorial structure of the tudinal study). Conclusions The QOL9 is a good BPH HRQL question-QOL20, a nine-item questionnaire (QOL9) was constructed using stepwise linear regression and factorial naire, including an assessment of patients' perceived sexual-life status; it easy to administer, accurate, reproanalysis. The feasibility and reliability of the QOL9 were analysed in a cross-sectional case-control study ducible and responsive to change with treatment. We suggest that the QOL9 be substituted for the QOL20 and a longitudinal cohort study, including symptomatic patients with BPH treated for 6 months with and administered in addition to the International Prostate Symptom Score to obtain a better assessment an a 1 -blocker (alfuzosin). Results The reduction of the QOL20 to QOL9 showed a of the patients' perception of their disease. Keywords Benign prostatic hyperplasia, quality of life, minimal loss of information (90-95% of the variance of QOL20 was explained by QOL9) and lead to a threepatients' perceived sexuality, a-blockers, alfuzosin dimensional structure: well being, patients' perceived questionnaire and the simplicity/acceptability of a short Introduction questionnaire. To obtain the most favourable explanatory/simplicity ratio, one generally accepted compromise BPH is a common disorder which is rarely lifethreatening but may aÂect the patient's perceived quality [4] is to start by constructing a lengthy questionnaire, to test it on a target population and then to condense it of life (QOL) [1]. The advent of new, eÂective treatments and increased public awareness of the disease have led by theoretical mathematical modelling, keeping the questions which give the most pertinent information at more younger men to seek advice earlier to obtain relief from their urinary symptoms. It is generally accepted baseline and during treatment. Therefore, it is necessary to confirm that the short-form questionnaire has retained that symptom severity does not correlate with perceived 'bother' [2] or QOL [3] indices. To further evaluate these the psychometric qualities of the initial questionnaire, with no major loss of information. This 'simplification' therapeutic modalities and their clinical response, it is necessary to carry out long-term outcome studies involvapproach was applied to an original BPH HRQL questionnaire consisting of 20 self-administered items in the form ing large cohorts of patients assess...

Medical therapy for benign prostatic hyperplasia: sexual dysfunction and impact on quality of life

“…10 The primary tools used to determine the presence of LUTS include the International Prostate Symptom Score (IPSS), the American Urological Association (AUA) Symptom Index, 11 the Danish Prostate Symptom Score (DAN-PSS), 12 and the International Continence Society questionnaire. 13 Other tools that measure the effect of LUTS on quality of life include the BPH Impact Index, 14 the UROLIFE Scale, 15 the BPH Health-related Quality of Life Survey, 16 and the bothersomeness question included in the IPSS (Bother Score).…”

The Relationship between LUTS and sexual function

“…A self-administered 41-item postal questionnaire was used and a response received from approximately 2400 men (70% response rate). Included in the questionnaire was the I-PSS 11 and three standard sexual function scores: the Danish (DAN)-PSS-1sex, 12 the BPH-QL9 13 and the International Index of Erectile Function (IIEF). 14 …”

Impact of treatment of BPH on sexuality

“…The Brief Sexual Function Inventory (SFI) 7 The International Index of Erectile Function (IIEF) 8 Urolife Scale 9 The Danish Prostatic Symptom Score (DAN-PSS) 10,11 Of these, the SFI and the IIEF have been developed specifically to measure male sexual function.…”
