Abstract
in English, Spanish

Objective: Given the evidence missing from validity studies that replicate the internal structure of the Mental Health Inventory - 5 (MHI-5) in Peruvian adolescents, this study performs a preliminary evaluation of the psychometric properties of MHI-5, specifically its internal structure.

Methods: The sample was 75 students of both sexes from a private high school-level educational institution, in the Casma city (Lima, Peru). The analysis was performed by applying a confirmatory factor analysis approach within the modeling of structural equations.

Results: A single significant dimension was found to be viable for interpreting the scores, but the fit was substantially improved when a factor was introduced that represented the effect of two item negative phrasing. On the other hand, the internal consistency was greater than .70, and it is considered satisfactory given its brevity.

Conclusions: It is concluded that the MHI-5 maintains the essential one-dimensionality, but it is required to introduce the possible effect of the method due to the content of some of its items. Consistency reliability was acceptable for screening purposes. The following steps are discussed to accumulate more validity evidence, suggesting to develop a shorter version without the problematic items, to reduce the potential response bias.

Objetivo: Dada la ausencia evidente de validaciones que repliquen la estructura interna del Inventario de Salud Mental - 5 (MHI-5) en adolescentes peruanos, el presente estudio realiza una evaluación preliminar de las propiedades psicométricas del MHI-5, específicamente de su estructura interna.

Métodos: La muestra fue de 75 estudiantes de ambos sexos de una institución educativa privada de nivel secundario del distrito de Casma (Lima, Perú). El análisis se realizó mediante la aplicación de un enfoque confirmatorio de análisis factorial dentro el modelamiento de ecuaciones estructurales.

Resultados: Se obtuvo que una sola dimensión significativa es viable para interpretar sus puntajes, pero el ajuste mejoró sustancialmente cuando de introdujo un factor que representó el efecto del fraseo negativo de dos ítems. Por otro lado, la consistencia interna fue mayor a 0,70, considerada como satisfactoria dada su brevedad.

Conclusiones: Se concluye que el MHI-5 mantiene la unidimensionalidad esencial, pero se requiere introducir el posible efecto del método debido al contenido de alguno de sus ítems. La confiabilidad de consistencia fue aceptable para propósitos de tamizaje. Se discuten los siguientes pasos para acumular más evidencias de validez, sugiriéndose desarrollar una versión más abreviada sin los ítems problemáticos, para reducir el potencial sesgo de respuesta.
