Multidimensional scale for affective disorders-MSAD: psychometric indicators generation and regulations scale clinical use

En este trabajo se desarrolló un estudio instrumental correspondiente a la tercera fase del proceso de estandarización de la Escala Multidimensional de Trastornos Afectivos-EMTA. Su propósito fue la generación de indicadores psicométricos y escalas normativas de uso clínico a partir de una muestra de 60 sujetos con diagnóstico de trastornos del estado de ánimo, elegidos por un muestreo no probabilístico, por criterio de expertos. Se administraron tres instrumentos psicométricos: EMTA (Subescala de manía α=.87 - Subescala de Depresión α=.958), el Inventario de Depresión de Beck - II (α=.901) y el Inventario Chino de Polaridad (α=.901 y α=.826). Los resultados indicaron que los ítems se ajustan satisfactoriamente a los parámetros de los Modelo Lineal (TCT) y el modelo de crédito parcial de Rasch, evidenciando un ajuste monotónico creciente de los reactivos, con lo cual se corrobora el cumplimiento del principio de la invarianza en la medición del rasgo latenteIn this assignment it development an instrumental study corresponding to the third phase of EMTA standardization. The main was to generate psychometric indicators and regulations scales of clinic use from a 60 subject sample with mood disorder diagnostic selected by a non- probability sampling per expert judges. Three psychometric instruments was administer: EMTA (Mania Subscale α=.87 - Depression Subscale α=.958), Beck Depression Inventory - II (α=.901) and Chinese Polarity Inventory (α=.901 y α=.826). The results indicated items adjust succesfully to Lineal Models parameters and Rasch partial credit model, showing an increasing monotonic adjustment of reagents which bear out fulfillment the principle of invariance in the latent trait measurin

Sexual risk among Colombian adolescents: knowledge, attitudes, normative beliefs, perceived control, intention, and sexual behavior

Background: Colombia has one of the highest rates of the human immunodeficiency virus (HIV) and pregnancies - both of which are influenced by lack of condom use -, among adolescent population in Latin America; however, the mechanisms underlying the inconsistent use of condoms in this population are poorly understood. This descriptive and cross-sectional study’s purpose was to examine sexual behavior and its precursors using the theory of planned behavior (TPB) and considering gender-based differences. Another objective was to study the mediating effect of intention in the relationship between behavior precursors and condom use based on the TPB. Methods: We recruited 1100 adolescents aged between 14 and 19 years old (M = 15.94, SD = 1.30, 54.4% female) from Bogotá and Barranquilla, two of the cities with highest adolescent birth rates among adolescents in Colombia. Sociodemographic variables, knowledge on HIV and other sexually transmitted infections (STIs), HIV/AIDS-related attitudes, including attitudes toward the use of condoms, normative beliefs, perceived behavioral control, behavioral intention, and sexual behavior were assessed using self-reports. All analyses were run using SPSS v25. The indirect effect of intention to explain the relationship between precursors and the use of condoms during sexual intercourse was estimated using the PROCESS v3 macro. Results: Descriptive analyses suggest a high risk of contracting sexually transmitted infections and unplanned pregnancies associated to inconsistent condom use, medium-low level of knowledge about sexual health, low normative beliefs regarding peers’ condom use, and a certain perceived difficulty for using condoms. Condoms are used 71% of the times they have sex, but only 22% of the participants use them consistently; girls use condoms more consistently than boys. Sexual risk characteristics differed significantly by gender. Mediation analyses indicated that condom use intention mediates the relationship between behavioral precursors and frequency of condom use, according to the TPB. Conclusions: Findings provide a better understanding of sexual risk and highlight important implications for the sexual and reproductive health of adolescents. There is a need of designing and implementing protocolized sexual health promotion programs in schools with the aim of reducing sexual risk behaviors in Colombian adolescents

Adaptation of an effective school-based sexual health promotion program for youth in Colombia

Rationale: Given the disproportionate impact of HIV and STIs among youth in Latin America, there is a compelling need for effective sex education programs. In particular, Colombia lacks a nationally standardized youth sex education program, despite the fact that 15 to 24-year-olds accounted for the highest incidence and prevalence rates of HIV and STIs in the nation. In an attempt to fill this void, our team adapted COMPAS, a Spanish school-based sexual health promotion intervention, for Colombian adolescents. Objective: This study describes the adaptation process that resulted in a modified version of COMPAS for youth in Colombia. Method: We employed a systematic cultural adaptation process utilizing a mixed methods approach, including intervention adaptation sessions with 100 young adolescents aged 15–19. The process included six steps: 1) consulting international researchers and community stakeholders; 2) capturing the lived experiences of a diverse sample of colombian youth; 3) identifying priorities and areas in need of improvement; 4) integrating the social cognitive theory, information-motivation-behavioral skills model, and an ecological framework for colombian youth; 5) adapting intervention content, activities, and materials; and 6) quantitative evaluation of COMPAS by Colombian youth. Results: The adapted intervention incorporates elements common to effective youth sex education interventions, including: a solid theoretical foundation, sexual communication skills and social support for protection, and guidance on how to utilize available cultural- and linguistic-appropriate services. In addition, the adapted intervention incorporates cultural and linguistic appropriate content, including an emphasis on tackling machismo to promote risk reduction behaviors. Conclusions: The systematic adaptation approach to sexual health intervention for youth can be employed by researchers and community stakeholders in low-resource settings for the promotion of health wellness, linkage to care, and STI and unplanned pregnancy prevention for youth

Multidimensional scale for affective disorders-MSAD: Analysis from the classic tests theory and the item response theory

This research responds to one phase of the process for the design and standarization of the MSAD Multidimentional Scale of Affective Disorders -EMTA in Spanish-, whose purpose was to analyze MSAD, from the Classical Test Theory (CTT) and the Item Response Theory (TRI), from a sample of 384 students enrolled to three universities in Barranquilla, aged between 17 and 26 years. This is considered an instrumental study, due to its purpose. The data were collected through he administration of three instruments: Scale Multidimensional Affective Disorder, The Beck Depression Inventory (α= .791) and the self-administered Altman Scale (α= .566). Finally, results were reported as adjusted to the parameters of both models. Analysis from the TCT showed high Cronbach alpha indexes for both subscales (α= .942 for the Depression Subscale and α = .864 for the Subscale Mania), as well as high internal item-scale correlations above .3 for all items. Since the TRI, reliability in the case of Depression .88 (individuals) and .99 (items) were reported, while rates regarding Mania were .84 (persons) and .87 (items). Results retained an increasing monotonic confguration; thus the principle of invariance in measuring the latent trait is corroborated.La presente investigación responde a una de las fases del proceso de diseño y estandarización de la Escala Multidimensional de Trastornos Afectivos (EMTA), cuyo propósito fue su análisis desde la Teoría Clásica de los Test (TCT) y la Teoría de Respuesta al Ítem (TRI) a partir de una muestra de 384 estudiantes vinculados a tres instituciones de educación superior de Barranquilla, cuyas edades oscilaron entre los 17 y los 26 años de edad. Los datos fueron recolectados a través de la administración de tres instrumentos: la Escala Multidimensional de Trastornos Afectivos, el Inventario de Depresión de Beck (a= .791) y la Escala Autoaplicada de Altman (a= .566). Se reportaron resultados ajustados a los parámetros de ambos modelos. En el análisis desde la TCT, se evidenciaro
