Abstract

PURPOSE: We validated the Peyronie's Disease Questionnaire (http://www.auxilium.com/PDQ), a 15-question self-reported survey that measures the impact and severity of Peyronie's disease symptoms in 3 domains, including 1) psychological and physical symptoms, 2) penile pain and 3) symptom bother. MATERIALS AND METHODS: We used baseline data from 2 phase 3 clinical trials (334 and 345 patients, respectively) of collagenase clostridium histolyticum treatment for Peyronie's disease associated penile curvature and bother. Collected data included PDQ domain scores, International Index of Erectile Function scores, objective penile curvature measures and patient reported Peyronie's disease symptom severity. Psychometric analyses included confirmatory factor analysis, inter-item reliability, and tests of convergent and discriminant validity, all related to the overall construct validity of the scale. RESULTS: Confirmatory factor analysis supported the conceptual framework of the PDQ with 3 confirmed subdomains. Each scale showed good consistency, ie internal reliability (each Cronbach α >0.70). Convergent and discriminant validity were noted in the pattern of associations between PDQ domains and other Peyronie's disease measures. PDQ domain scores significantly differed between patients with vs without erectile dysfunction and between patients with vs without Peyronie's disease related symptom distress, further supporting PDQ construct validity. CONCLUSIONS: This study confirms the conceptual framework, factor structure, and convergent and discriminant validity of the PDQ psychological and physical symptoms, penile pain, and symptom bother domains. Used in conjunction with objective penile curvature measurements, the PDQ can serve as a valuable diagnostic tool or outcome measure to assess treatment related improvements in Peyronie's disease symptoms.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The study used validated psychometric tests: the Generalized Anxiety Disorder-7, the Patient Health Questionnaire-9, and the Peyronie's Disease Questionnaire symptom bother.

    “All patients completed the following questionnaires: a visual analog scale (VAS) questionnaire for pain assessment; the International Index of Erectile Function (IIEF) for the evaluation of erectile function; and three validated psychometric tests: the Generalized Anxiety Disorder-7 questionnaire (GAD-7, for the assessment of anxiety), the Patient Health Questionnaire-9 (PHQ-9, for the assessment”
  • The PDQ bother mean score was 8.8, slightly higher than the 6.3-8.0 reported by other authors.

    “In our research, we also found a slightly higher psychosexual impact (PDQ bother mean score = 8.8) compared to those reported by other authors (6.3–8.0) [60,64,83].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
