Beliefs about penis size: validation of a scale for men ashamed about their penis size.

INTRODUCTION: No measures are available for understanding beliefs in men who experience shame about the perceived size of their penis. Such a measure might be helpful for treatment planning, and measuring outcome after any psychological or physical intervention. AIM: Our aim was to validate a newly developed measure called the Beliefs about Penis Size Scale (BAPS). METHOD: One hundred seventy-three male participants completed a new questionnaire consisting of 18 items to be validated and developed into the BAPS, as well as various other standardized measures. A urologist also measured actual penis size. MAIN OUTCOME MEASURES: The BAPS was validated against six psychosexual self-report questionnaires as well as penile size measurements. RESULTS: Exploratory factor analysis reduced the number of items in the BAPS from 18 to 10, which was best explained by one factor. The 10-item BAPS had good internal consistency and correlated significantly with measures of depression, anxiety, body image quality of life, social anxiety, erectile function, overall satisfaction, and the importance attached to penis size. The BAPS was not found to correlate with actual penis size. It was able to discriminate between those who had concerns or were dissatisfied about their penis size and those who were not. CONCLUSIONS: This is the first study to develop a scale for measurement of beliefs about penis size. It may be used as part of an assessment for men who experience shame about the perceived size of their penis and as an outcome measure after treatment. The BAPS measures various manifestations of masculinity and shame about their perceived penis size including internal self-evaluative beliefs; negative evaluation by others; anticipated consequences of a perceived small penis, and extreme self-consciousness.

Definitions of terms, processes and a minimum dataset for transperineal prostate biopsies: a standardization approach of the Ginsburg Study Group for Enhanced Prostate Diagnostics.

OBJECTIVES: To define terms and processes and agree on a minimum dataset in relation to transperineal prostate biopsy procedures and enhanced prostate diagnostics. To identify the need for further evaluation and establish a collaborative research practice. PATIENTS AND METHODS: A 19-member multidisciplinary panel rated 66 items for their appropriateness and their definition to be incorporated into the international databank using the Research and Development/University of California Los Angeles Appropriateness Method. The item list was developed from interviews conducted with healthcare professionals from urology, radiology, pathology and engineering. RESULTS: The panel agreed on 56 items that were appropriate to be incorporated into a prospective database. In total, 10 items were uncertain and were omitted. These items were within the categories: definitions (n = 2), imaging (n = 1), surgical protocols (n = 2) and histology (n = 5). CONCLUSIONS: The components of a minimum dataset for transperineal prostate biopsy have been defined. This provides an opportunity for multicentre collaborative data analysis and technique development. The findings of the present study will facilitate prospective studies into the application and outcome of transperineal prostate biopsies.
