Screening hypersexuality in Parkinson's disease in everyday practice

Area of Science:

• Neuroscience
• Psychiatry
• Clinical Psychology

Background:

• Parkinson's disease (PD) is associated with impulse control disorders, including hypersexuality.
• Existing screening tools for hypersexuality may not be suitable for PD patients in clinical practice.

Purpose of the Study:

• To develop and validate a brief, reliable screening instrument for hypersexuality tailored for patients with Parkinson's disease (PD).
• To create a tool that can be easily administered in routine clinical settings.

Main Methods:

• The original 25-item Sexual Addiction Screening Test (SAST) was adapted and shortened through successive item reductions in a PD population.
• The adapted questionnaire (PD-SAST) was administered to 159 PD patients to assess acceptability, dimensionality, construct validity, and criterion validity.

Main Results:

• A five-item version (PD-SAST) was developed with a recommended cut-off score of 2.
• Psychometric analysis identified three key factors: "Preoccupation," "Cannot stop," and "Relationship disturbance."
• The PD-SAST demonstrated high discriminant validity with an ROC area under the curve of 0.96.

Conclusions:

• The PD-SAST is an acceptable and effective screening instrument for hypersexuality in Parkinson's disease patients.
• The tool is ready for clinical use and captures multidimensional aspects of hypersexuality.
