MONTANO ESTUPINAN, Diana Carolina; PARDO JAIME, Leonardo  and  MARCHAL-BERTRAND, Laurent. Estimation of the psychometric properties of the sex addiction measurement instrument (MAS). Suma Psicol. [online]. 2022, vol.29, n.2, pp.146-156.  Epub May 08, 2023. ISSN 0121-4381.


The MAS instrument, a test to assess sex addiction, has presented drawbacks at the factorial level. For this reason, this research sought to estimate the psychometric properties of the sex addiction measurement instrument (MAS) in Colombian population.


Initially, an expert judgment was carried out to establish the validity of content through Aiken’s V, then the MAS and the sexual inhibition/arousal scale (SIS/SES) were applied to 337 participants through a form web (Google forms) of which 312 met the inclusion criteria (221 women and 91 men) aged between 18 and 65 years (x_ = 28.49, SD = 9.77). Using SPSS, Cronbach’s alpha, Pearson’s correlation, and a factorial analysis with Varimax rotation were calculated.


The analyzes showed a good reliability, a correlation adjusted to what was expected in relation to the SIS/SES test and the factorial analysis showed six factors that present differences in comparison with the initially proposed test.


The sex addiction measurement test (MAS) has an adequate level of reliability, but does not have adequate construct validity.
