title: Factor analysis of the modified Sexual Adjustment Questionnaire-Male.
abstract: OBJECTIVE
  The Sexual Adjustment Questionnaire (SAQ) is used in National Cancer Institute-sponsored clinical trials as an outcome measure for sexual functioning. The tool was revised to meet the needs for a clinically useful, theory-based outcome measure for use in both research and clinical settings. This report describes the modifications and validity testing of the modified Sexual Adjustment Questionnaire-Male (mSAQ-Male).
  
  
  METHODS
  This secondary analysis of data from a large Radiation Therapy Oncology Group trial employed principal axis factor analytic techniques in estimating validity of the revised tool. The sample size was 686; most subjects were White, older than the age 60 years, and with a high school education and a Karnofsky performance scale (KPS) score of greater than 90.
  
  
  RESULTS
  A 16-item, 3-factor solution resulted from the factor analysis. The mSAQ-Male was also found to be sensitive to changes in physical sexual functioning as measured by the KPS.
  
  
  CONCLUSIONS
  The mSAQ-Male is a valid self-report measure of sexuality that can be used clinically to detect changes in male sexual functioning.
