title: Screening hypersexuality in Parkinson's disease in everyday practice.
abstract: OBJECTIVE
  The purpose of this study was to develop a short and reliable measure of hypersexuality that could be used in everyday practice in patients with Parkinson's disease (PD).
  
  
  METHODS
  The original questionnaire containing twenty-five-items, the Sexual Addiction Screening Test (SAST), was shortened and tested in a PD population.
  
  
  METHODS
  Successive reductions were performed until a final set of items satisfied the model fit requirements. The testing phase consisted of administering the SAST questionnaire to 159 PD patients. It included i) acceptability, ii) dimensionality construct validity, and iii) a complete general correlation structure of data. Finally, criterion validity of the final version of the instrument was assessed.
  
  
  RESULTS
  The initial questionnaire was reduced to five items (PD-SAST) with a cut-off score of 2. Psychometric analysis revealed three factors corresponding to "Preoccupation", "Cannot stop" and "Relationship disturbance". The discriminant validity of the PD-SAST was high (ROC area under the curve: 0.96).
  
  
  CONCLUSIONS
  The PD-SAST performs well as a screening instrument. It has been found to be acceptable to patients and is ready for use. Moreover, it tests multidimensional aspects of hypersexuality.
