The dimensionality of DSM5 alcohol use disorder in Puerto Rico.
Test the dimensionality and measurement properties of lifetime DSM-5 AUD criteria in a sample of adults from the metropolitan area of San Juan, Puerto Rico.



Cross-sectional study with survey data collected in 2013-2014.



General population.



Random household sample of the adult population 18 to 64years of age in San Juan, Puerto Rico (N=1510; lifetime drinker N=1107).



DSM-5 alcohol use disorder (2 or more criteria present in 12months).



Lifetime reports of AUD criteria were consistent with a one-dimensional model. Scalar measurement invariance was observed across gender, but measurement parameters for tolerance varied across age, with younger ages showing a lower threshold and steeper loading.



Results provide support for a unidimensional DSM-5 AUD construct in a sample from a Latin American country.
