Psychometric Properties of the Spanish Version of the Online Sexual Addiction Questionnaire: An Exploratory Study Using a Sample of Convicted Sex Offenders

This study explored the psychometric properties of the Online Sexual Addiction Questionnaire (OSA-Q). In total, 100 sexual offenders completed the OSA-Q Spanish version, along with the Millon Clinical Multiaxial Inventory-III (MCMI-III) for the assessment of related impairment. Thirty-four individuals with social-desirability bias were extracted from the sample. A four-factor structure accounted for 77% of the variance and internal consistency was strong (a = .97). Additionally, correlations with related clinical scales were statistically significant. Overall, online sexual offenders showed higher scores on the OSA-Q than contact-exclusive offenders. According to our results, the OSA-Q shows promise as a screening in forensic samples.
