Resumen: El Inventario de Depresión Rasgo-Estado (IDERE) fue diseñado para evaluar la depresión como estado y como rasgo. Este trabajo se propuso estudiar su utilidad para identificar casos en los que se estima depresión clínica de acuerdo a los criterios del DSM-IV. La muestra estuvo constituida por 1984 sujetos de cuatro países: 503 españoles, 330 cubanos, 477 colombianos y 674 mexicanos. Se utilizó la Escala del Centro de Estudios Epidemiológicos de la Depresión (CES-D) para estudiar la validez concurrente y el Inventario de Síntomas Depresivos de Riquelme para identificar casos que cumplieran criterios del DSM-IV para diagnóstico de un episodio depresivo. El análisis de las curvas ROC por grupos edades y géneros, así como para Cuba, México y España, mostró que ambas subescalas tenían buena precisión, sin embargo para la muestra colombiana ninguna de las subescalas obtuvo resultados aceptables. Se encontraron diferencias significativas en puntuaciones del IDERE atribuibles a sexo, país, edad; y a la interacción entre estas variables. Ambas subescalas obtuvieron correlaciones significativas y positivas con el CES-D. Los resultados hablan a favor de la validez de criterio y convergente del IDERE y de su valor para la identificación de personas con posible depresión en países iberoamericanos.

A study containing samples from four Iberian-American nations. Abstract: State-Trait Depression Inventory (IDERE) is a self-evaluating inventory designed to evaluate depression as a state and as a trait. This work set a goal to study its usefulness to identify cases in which clinical depression -based on the DSM-IV criteria-are estimated. The sample was made up of 1984 individuals from four countries: 503 Spaniards, 330 Cubans, 477 Colombians and 674 Mexicans. The Scale of the Center for Epidemiological Studies on Depression (CES-D) was used in an effort to assess the concurrent validity and the Riquelme Inventory of Depressive Symptoms to pinpoint cases that comply with the DSM-VI criteria for the diagnosis of a depressive episode. The analysis of the ROC curves by age and gender groups, as well as for Cuba, Mexico and Spain, showed good accuracy rate in both scales. However, for the Colombian sample none of the subscales yielded acceptable outcomes. Significant differences were found in terms of gender, country, age and the interaction among these variables. Both subscales produced significant and positive correlations with CES-D. The results speak in favor of the validity of criteria and convergence with IDERE, as well as its value for the identification of people suffering from possible depression in Hispanic American countries. Key words: Depression; psychodiagnosis; IDERE; transcultural studies.

Background: There is a consensus that receiving satisfactory social support is crucial for elderly people experiencing chronic pain; however, no instruments have been validated for the Cuban population. The Medical Outcomes Study (MOS) is an instrument that has been widely validated across several countries, indicating significant psychometric properties to measure perceived social support; however, MOS has never been applied to Cubans. This study obtained evidence of the internal and external validity of the original MOS survey structure and its brief 8-item version in a sample of Cuban seniors with chronic pain.Methods: The sample included 200 Cuban single and retired seniors, with an intermediate level of education. The MOS Social Support Survey and a structured interview were conducted to obtain socio-demographic information and learn about the support perceived by elders in pain. A confirmatory factor analysis (CFA) was used to test the structure. Cronbach’s alpha and omega coefficients were considered for internal consistency, in addition to the relation between the item variance and error variance (Average variance extracted). Furthermore, Spearman’s rho coefficient was used to estimate the correlations between the MOS scores and the support assessment given by seniors in pain.Results: All the models assessed through the CFA indicated good adjustment indices. However, the brief version of the model gave better results. Of the coefficients assessing internal consistency, the 2-factor 8-item version indicated the best indicators and accounted for greater variance not attributable to the error. Both versions of the MOS and their corresponding sub-scales obtained significant positive correlations with the support received by seniors in pain.Conclusions: The MOS (4-factor) and the 8-item brief version (with 2 factors) present suitable evidence of structural validity, internal consistency, and external validity.
