RESUMO

La estructura dimensional e interna de los instrumentos puede variar significativamente según la población. El objetivo del estudio fue corroborar la estructura dimensional e interna de la escala de breve de Zung en personas dedicadas al reciclaje de residuos urbanos. Se diseñó un estudio metodológico. Una muestra de 206 adultos, entre 18 y 70 años (M=37,7; SD=12,5); 147 hombres y 59 mujeres. Los participantes diligenciaron los diez ítems de la escala. La estructura dimensional se probó mediante análisis factorial confirmatorio y calcularon índices de bondad del ajuste: chi cuadrado, RMSEA (Root Mean Square Error of Approximation), CFI (Comparative Fit Index), TLI (índice de Tucker-Lewis) y SMSR (Standardized Mean Square Residual). La estructura interna se probó con alfa de Cronbach y omega de McDonald. Se probó la estructura bidimensional: el primer factor (ánimo deprimido-ansiedad) y el segundo (anhedonia-cognición). Los índices de ajuste fueron chi cuadrado=126,83, grados de libertad=34, p=0,001; RMSEA=0,115 (IC90% 0,094-0,137), CFI=0,851, TLI=0,802 y SRMS=0,075. La primera dimensión mostró alfa de Cronbach y omega de McDonald de 0,80; y la segunda, alfa de 0,71 y omega de 0,72. No se corroboró la estructura de la escala de Zung para depresión. Una muestra mayor puede dar información más concluyente.


The dimensional and internal structure of the instruments can vary significantly according to the population. The objective of the study was to corroborate the dimensional and internal structure of the Zung's brief scale in people dedicated to the recycling of urban waste. A methodological study was designed. A sample of 206 adults, between 18 and 70 years (M=37.7, SD=12.5); 147 men and 59 women. Participants completed the ten items of the scale. The dimensional structure was tested by confirmatory factor analysis and calculated goodness-of-fit indexes: chi-square, RMSEA (Root Mean Square Error of Approximation), CFI (Comparative Fit Index), TLI (Tucker-Lewis index) and SMSR (Standardized Mean Square Residual). The internal structure was tested with Cronbach's alpha and McDonald's omega. The two-dimensional structure was tested: the first factor (depressed mood-anxiety) and the second (anhedonia-cognition). The fit indices were chi square=126.83, degrees of freedom=34, p=0.001; RMSEA=0.115 (IC90% 0.094-0.137), CFI=0.851, TLI=0.802, and SRMS=0.075. The first dimension showed both Cronbach's alpha and McDonald's omega of 0.80; and the second, alpha of 0.71 and omega of 0.72. The structure of the Zung scale for depression was not corroborated. A larger sample can give more conclusive information.
