Dimensionality and inclusion/exclusion of several criteria was studied using various analytic approaches. Objective: The study aimed to deepen our knowledge of the interrelationships between the diagnostic criteria for cocaine use disorder (CUD), applying three different analytical techniques: factor analysis, Item Response Theory (IRT) models, and network analysis. Methods: 425 (85.4% male) outpatients were evaluated for CUD using the Substance Dependence Severity Scale. Confirmatory Factor Analysis, 2-parameter logistic model (IRT) and network analysis were applied to analyze the relationships between the diagnostic criteria. Results: The results show that “legal problems” criterion is not congruent with the CUD measure on three analyses. Also, network analysis suggests the usefulness of the “craving” criterion. The criterion “quit/control” is the one that presents the best centrality indices and expected influence, showing strong relationships with the criteria of “craving,” “tolerance,” “neglect roles” and “activities given up.” Conclusions: Network analysis appears to be a useful and complementary technique to factor analysis and IRT for understanding CUD. The “quit/control” criterion emerges as a central criterion to understand CUD.

Estas fotografías fueron tomadas en una zona llana de la costa cercana a Keiss, en el condado de Caithness, Escocia, con marea baja, donde la “vieja arenisca roja” forma un lecho duro que se sumerge superficialmente en el mar perfectamente transparente. A unos 10 metros en el oleaje, las rocas se quiebran en el agua profunda, abriéndose a una parte menos accesible del mundo acuático. Las criaturas que encontré allí no eran espectaculares, ni raras ni fascinantes. No había colores llamativos, ni misterios sublimes—simplemente organismos en su propio mundo, solitarios y perfectamente imperturbados, algunos esperando ser tragados por la próxima marea, otros moviéndose a un ritmo increíblemente lento., The pictures were taken on a flat part of the coast near Keiss, County Caithness, Scotland, at low tide, where “Old Red” Sandstone forms a hard bed dipping shallowly into the perfectly transparent sea. About 10 metres into the surf, the rocks break off into deep water, opening to a less accessible part of the water-bound world. The creatures I found there were neither spectacular, nor rare or exciting. There were no loud colours, no sublime mysteries—just organisms in their own world, solitary and perfectly undisturbed, some waiting to be engulfed in the next high tide, others moving around at incredibly slow rates.
