Sexual Compulsivity Scale, Compulsive Sexual Behavior Inventory, and Hypersexual Disorder Screening Inventory:...

Area of Science:

• Psychiatry
• Psychometrics
• Clinical Psychology

Background:

• Limited epidemiological, behavioral, and clinical data on sexual compulsivity in Brazil.
• Need for validated instruments to assess sexual compulsivity and hypersexual disorder in the Brazilian population.

Purpose of the Study:

• Adapt and validate the Sexual Compulsivity Scale (SCS), Compulsive Sexual Behavior Inventory (CSBI-22), and Hypersexual Disorder Screening Inventory (HDSI) for use in Brazil.
• Evaluate the reliability, validity, and psychometric properties of these instruments.

Main Methods:

• Cross-cultural adaptation of instruments from English to Portuguese following international guidelines.
• Psychiatric assessment and self-reported measures administered to 153 participants.
• Factor analysis, reliability (internal consistency, temporal stability), and validity (construct, convergent, discriminant) analyses were performed.

Main Results:

• All scales (SCS, CSBI-22, HDSI) demonstrated good internal consistency (alpha >.75) and high temporal stability (>.76).
• Factor analysis supported a one-factor structure for SCS and HDSI, and four factors for CSBI-22 (two utilized).
• Measures showed strong correlations with the Sexual Addiction Screening Test and moderate correlations with Impulsive Sensation Seeking, indicating good construct validity. HDSI achieved 71.93% sensitivity and 100% specificity.

Conclusions:

• The adapted SCS, CSBI-22, and HDSI exhibit excellent psychometric properties for assessing sexual compulsivity in Brazil.
• Findings support the conceptualization of hypersexuality as a consistent cluster of problematic symptoms across validated measures.
• These validated instruments are crucial for future research and clinical practice regarding sexual compulsivity in Brazil.
