Introducción. Las escalas breves para identificar trastornos depresivos conservan la utilidad de las escalas extensas como instrumentos para tamizaje. Sin embargo, no se cuenta con una escala de estas características validada en población general colombiana. Objetivo. Diseñar una escala abreviada de la escala de Zung para depresión para tamizaje de episodio depresivo mayor en adultos residentes en la comunidad general. Materiales y métodos. A partir de la aplicación de la escala de Zung de veinte items se tomaron los diez items que mostraron la mayor correlación con la puntuación total. A estos items escogidos se les determinó la validez de constructo y la validez de criterio. Resultados. Los diez items escogidos mostraron una consistencia interna de 0,803, un único factor principal que explicaba el 36,6% de la varianza y sensibilidad de 95,5%, especificidad de 70,3%, kappa media de Cohen de 0,415 y 0,898 de área bajo la curva receptor-operador. Conclusiones. La escala abreviada de Zung muestra propiedades psicométricas similares a la escala extensa que permiten la utilización como instrumento de tamizaje en población adulta general.Palabras clave: estudios de validación, tamizaje masivo, población urbana, adulto. Validity of the brief Zung's scale for screening major depressive episode among the general population from Bucaramanga, ColombiaIntroduction. Brief scales for identiying depressive disorder are as useful as long scales for screening. However, a validated scale with these characteristics is not avalaible in Colombia. Objective. To design a brief Zung's self-rating depression scale in order to screen major depressive episodes among adults dwelling in the general community. Materials and methods. After filling-out the 20-item Zung's self-rating depression scale, the ten items with the higher correlation with total score were selected. Construct and criterion validity were computed for these ten items. Results. The ten chosen items showed an internal consistency of 0,803, one factor that accounted for 36,6% of the variance; sensitivity was 95,5%; specificity, 70,3%; Cohen's kappa, 0,415; and area under receptor-operator curve, 0,898. Conclusions. The brief Zung's self-rating depression scale exhibits psychometric properties similar to the long version. This brief scale can be used as a screening device in the general population.
Introducción. El consumo diario de cigarrillo se asocia con una alta morbimortalidad en la adultez. Este patrón de consumo se inicia habitualmente en la adolescencia temprana. En adolescentes, el consumo diario de cigarrillo es factor de predicción importante del uso de sustancias ilegales que pueden producir dependencia. Se desconoce la frecuencia de consumo diario de cigarrillo en estudiantes colombianos. Objetivo. Determinar la prevalencia y los factores asociados con el consumo diario de cigarrillo en adolescentes estudiantes de sexto a noveno grado del área metropolitana de Bucaramanga, Colombia. Materiales y métodos. Se realizó un estudio transversal. Una muestra probabilística de 2.586 estudiantes diligenció en forma anónima una encuesta que indagaba el consumo de sustancias legales e ilegales. Resultados. La edad promedio fue 13,0 años; 54,9% era varones; 32,0% cursaba sexto grado; 31,7%, séptimo; 25,2%, octavo, y 11,1%, noveno; 67,1% estudiaba en colegios oficiales. El consumo diario de cigarrillo durante el mes anterior fue de 3,8% (IC95% 2,7 a 4,9). La regresión logística mostró que tener un mejor amigo fumador o consumidor de alcohol (OR=3,71; IC95% 1,71 a 8,04), referir mal rendimiento académico (OR=3,83; IC95% 1,03 a 14,18) y tener más años de edad (OR=1,44; IC95% 1,19 a 1,75) se asociaba con el consumo diario de cigarrillo. Conclusión. Uno de cada 26 estudiantes de básica secundaria del área metropolitana de Bucaramanga consume diariamente cigarrillo. Tener un mejor amigo fumador es el factor más fuertemente asociado.

Social factors associated with the daily cigarette smoking among middle-school student adolescents in Bucaramanga, ColombiaIntroduction. Daily cigarette smoking is associated with high morbidity and mortality in adults. This pattern of tobacco use is established during the early adolescence. Among adolescents, daily cigarette smoking is a strong predictor of illegal, addictive substance use. The prevalence of daily cigarette smoking is not known in Colombian adolescent middle-school students. Objective. To assess smoking prevalence, daily cigarette smoking and associated factors among middle school-students in Bucaramanga, northeast Colombia. Materials and methods. An anonymous questionnaire concerning illegal and legal substance use was administered to a random sample of 2,586 students. Results. The group mean age was 13.0 years; 54.9% was male; 32.0% was in sixth grade, 31.7% in seventh, 25.2% in eighth and 11.1% in ninth grade, with 67.1% enrolled in public schools. The prevalence of daily cigarette smoking lasting the month prior to the questionnaire was 3.8% (95%CI 2.7-4.9). Logistic regression showed a significant association between being the best friend of a smoker or a drinker of alcohol (OR=3.71; 95%CI 1.71-8.04), having low academic performance perception (OR=3.83; 95%CI 1.0-14.2), and being older age (OR=1.4; 95%CI 1.2-1.8).Conclusions. These data demonstrated that one in 26 m...
Introducción. La prevalencia de los trastornos de la conducta alimentaria ha aumentado en los últimos años, creando la necesidad de detectar precozmente los casos en poblaciones en riesgo. Objetivo. Determinar la consistencia interna, la reproducibilidad y la validez de criterio del cuestionario SCOFF (del acrónimo en inglés, sick, control, one, fat, food) en universitarias para el tamizaje de los trastornos de la conducta alimentaria. Materiales y métodos. Se llevó a cabo un estudio de validación con muestreo transversal al azar de 385 estudiantes entre 1.587 elegibles de 6 facultades de la Universidad Autónoma de Bucaramanga, Colombia. Se aplicó de manera independiente el cuestionario SCOFF y la entrevista diagnóstica internacional compuesta. Resultados. 149 (38,7%) estudiantes fueron positivos en la puntuación del cuestionario SCOFF para los trastornos de la conducta alimentaria. La sensibilidad fue de 78,4% (IC95%, 64,3%-88,2%), la especificidad de 75,8% (IC95%, 68,9%-81,6%), el valor pronóstico positivo de 46,5% (IC95%, 35,8%-57,5%) y el valor pronóstico negativo de 92,9% (IC95%, 87,3%-96,2%). El área bajo la curva ROC fue de 0,823 (IC95%, 0,760-0,887), el alfa de Cronbach de 0,480 y la kappa media de Cohen de 0,433 (IC95%, 0,315-0,552). La concordancia prueba-reprueba fue de 91,6% (IC95%, 85,5%-95,7%). Conclusión. El cuestionario SCOFF parece ser una buena alternativa como instrumento de tamizaje para detectar los trastornos de la conducta alimentaria en mujeres universitarias de Colombia, por su sencillez y rapidez de administración.Palabras clave: anorexia nerviosa, bulimia nerviosa, trastornos de la conducta alimentaria, cribado, validez, reproducibilidad de resultados. Validation of the SCOFF questionnaire for screening of eating disorders in university womenBackground. The prevalence of eating disorders has been steadily increasing in recent years. This has led to a growing sense that instruments are necessary for early detection in high risk populations. Objective. Herein the SCOFF (sick, control, one, fat, food) questionnaire was examined for its internal consistency, reliability, and criterion validity in screening eating disorders among university women. Materials and methods. A sample of 385 students was selected at random from six schools in the Universidad Autónoma de Bucaramanga, Colombia, and were evaluated independently with the SCOFF questionnaire and a CIDI (Composite International Diagnostic Interview). Results. A total of 149 (38.7%) students were positive for eating disorder syndromes according to the SCOFF questionnaire, whereas 82 (21.2%) students met eating disorder using the CIDI. SCOFF questionnaire sensitivity was 78.4% (95%CI 64-88%), specificity 75.8% (95%CI 69-82%), ROC curve area 0.823 (95%CI 0.76-0.89), Cronbach s alpha 0.480, Cohen s kappa 0.433 (95%CI 0.32-0.55), and test-retest concordance 91.6% (95%CI 86-96). Conclusion. These data indicate the SCOFF questionnaire to be a good scale in screening for eating disorders among university women. Its added advantages are that th...
Background: The Zung’s rating instrument for anxiety disorders has been used in several Colombian researches. Its internal consistency and factor structure have not been reported among university students. Objective: To calculate the internal consistency and explore the factor structure of three versions of the Zung’s rating instrument for anxiety disorders among university students. Method: Two-hundred and twenty-one medicine and psychology students of a private university in Cartagena, Colombia, completed the 20-item version of the Zung’s rating instrument for anxiety disorders. The mean of age of students was 20.5 years (SD=2.6), 64.4% were women, and 54.3% studied medicine. Cronbach alpha was computed and exploratory factor analysis was done for the three versions. Results: The 20-item version of the Zung’s rating instrument for anxiety disorders presents Cronbach alpha coefficient of 0.77 and three principal factors accounted for 40.1% of the total variance. The 10-item version showed Cronbach alpha of 0.83 and two-dimensional structure responsible of 54.0% of the total variance. The 5-item version showed Cronbach alpha of 0.74 and one-dimensional structure accounted for 49.5% of the total variance. Conclusions: The 10- and 5-item version of the Zung’s rating instrument for anxiety disorders present better psychometric properties than the original 20-item version. It is necessary to estimate the properties of these versions compared with a gold standard.
