ABSTRACT

Antecedentes: La identificación de los motivos por los cuales se consume marihuana se ha visto apoyada por instrumentos como el MMM. A pesar de su importancia, aún no se cuenta con versiones breves válidas de este en países latinoamericanos. Este trabajo busca cubrir esta carencia aportando evidencia de validez y confiabilidad, así como la invarianza estructural del MMM. Método: La muestra comprende 1164 consumidores de marihuana, varones y mujeres, con edades entre 18 y 49 años, de Lima y Callao. Resultados: El análisis factorial halló una estructura pentafactorial. La versión breve (MMM-P15) y extensa (MMM) muestran favorables propiedades de estructura y consistencia interna (ꙍ> .88, H > .84) con adecuados índices de ajuste del instrumento corto (RMSEA = .058 [IC 90% .050, .067], SRMR = .044, GFI = .99, TLI = .99, CFI = .99). Asimismo, ambas versiones mantienen la invarianza según el sexo y se encontró evidencia de validez interna (AVE > .50) y con otros constructos (CAST y SWLS). Conclusiones: El MMM-P15 evidencia propiedades psicométricas que respaldan su uso tanto en hombres y mujeres consumidores de marihuana, además es un instrumento corto, versátil y útil para fines de investigación incluso en contextos clínicos.(AU9


Background: The identification of the reasons for marijuana use has been supported by instruments such as the MMM. Despite its importance, there are still no valid brief versions of this instrument in Latin American countries. This paper seeks to fill this gap by providing evidence of validity and reliability, as well as the structural invariance of the MMM. Method:The sample consisted of 1164 male and female marijuana users, aged between 18 and 49 years, from Lima and Callao. Results: The factor analysis found a pentafactorial structure. The brief version (MMM-P15) and the wide MMM showed favorable properties from structure and reliability (ꙍ> .88, H > .84) with appropriate indicators of the short instrument adjustment (RMSEA = .058 [CI 90% .050, .067], SRMR = .044,TLI = .99, CFI = .99). Likewise, both versions maintain the invariance of the instrument according to sex and evidence of internal validity was found (AVE > .50). Aside from bringing evidence of validity with other constructs like CAST and SWLS scale. Conclusions:The MMM-P15 shows psychometric properties that support its use in both male and female marijuana users, and it is a short, versatile, and useful instrument for research pur-poses even in clinical settings.(AU)
