title: The Subjective Sexual Arousal Scale for Men (SSASM): preliminary development and psychometric validation of a multidimensional measure of subjective male sexual arousal.
abstract: BACKGROUND
  Sexual arousal is a multifaceted process that involves both mental and physical components. No instrument has been developed and validated to assess subjective aspects of male sexual arousal.
  
  
  OBJECTIVE
  To develop and psychometrically validate a self-administered scale for assessing subjective male sexual arousal.
  
  
  METHODS
  Using recommendations of the Food and Drug Administration (FDA) guidance on patient-reported outcome instruments, important aspects of male sexual arousal were identified via qualitative research (focus groups and interviews) of U.S. men with erectile dysfunction (ED) and healthy controls. After a preliminary questionnaire was developed by a panel of experts, a quantitative study of men with ED and controls was conducted to psychometrically validate the Subjective Sexual Arousal Scale for Men (SSASM).
  
  
  METHODS
  To develop a male sexual arousal scale and determine its factor structure, reliability, and construct validity.
  
  
  RESULTS
  Five aspects of male sexual arousal were identified from the qualitative focus groups and cognitive interviews. Men's preferred language for describing sexual arousal and preferred response formats were incorporated into the questions. Factor analysis of data from the quantitative study of 304 men aged 21 to 70 years identified five domains with eigenvalues >1: sexual performance (six items), mental satisfaction (five items), sexual assertiveness (three items), partner communication (three items), and partner relationship (three items). The five domains had a high degree of internal consistency (Cronbach's alpha values 0.88-0.94). Test-retest reliability over a 2- to 4-week period was high-moderately high (r values 0.75-0.88) for the five domain scores. Correlations between SSASM domain scores and standardized scale scores for social desirability, general health, life satisfaction, and sexual function demonstrated the construct validity of the scale.
  
  
  CONCLUSIONS
  Preliminary validation data suggest that the 20-item SSASM scale may be useful as a multidimensional, reliable, self-administered instrument for assessing subjective sexual arousal in men of different ages.
