Description: This study was aimed at estimating the internal consistency, distribution, factor structure and concurrent validity of a simplified format application for the Beck Depression Inventory with its 21 items rated on a 4-point scale. A non-probabilistic sample of voluntary participants formed by 100 married couples was investigated. The BDI scale presented a high internal consistency (alpha= .91). Its distribution was positively skewed (M = 11.36 and SD = 9.95). Two factors that explained 9.47% of the total variance were defined by the Cattell’s criterion. The first factor of 11 items (1, 2, 3, 4, 5, 6, 7, 9, 10, 13 and 19) was named depressive cognitive-emotional symptoms (alpha = .87); the second factor of 10 items was identified as somatized depression (8, 11, 12, 14, 15, 16, 17, 18, 20 and 21) (á = .85). The fit indexes were adequate. Reducing the indicator numbers per factor to five resulted in a good fit of the model, but equivalent to the one-factor model. BDI directly and mo- derately correlated (rS =.56) with negative affect (PANAS; Watson, Clark & Tellegen, 1988), severity of somatic symptoms (rS = .43) (SSS; Woolfolk & Allen, 2007) and alexithymia (rS = .41) (TAS20; Bagby, Parker & Taylor, 1994), and inversely and lowly with positive affect (rS = - .18). It is concluded that the format saves space and time in its application and possesses psychometric properties as good as the original scale
El presente estudio tuvo como objetivo estimar la consistencia interna, distribución, estructura factorial y validez concurrente de un formato de aplicación simplificado para el Inventario de De- presión de Beck con 21 reactivos de 4 puntos de rango. Se empleó una muestra no probabilística de participantes voluntarios conformada por 100 parejas casadas. La escala presentó una consis- tencia interna alta (á = .91). Su distribución fue asimétrica positiva (M = 11.36 y DE = 9.95). Con base en el criterio de Cattell se definieron dos factores que explicaron el 39.47% de la varianza total. Al primer factor de 11 reactivos (1, 2, 3, 4, 5, 6, 7, 9, 10, 13 y 19) se le denominó síntomas cognitivo-emocionales de depresión (á = .87); al segundo de 10 reactivos, factor de depresión so- matizada (8, 11, 12, 14, 15, 16, 17, 18, 20 y 21) (á = .85). Los índices de ajuste fueron adecuados. Al reducir a cinco indicadores por factor el modelo factorial mostró buen ajuste, pero equivalente al modelo unidimensional. La correlación fue directa y moderada (rS = .56) con afecto negativo (PA- NAS; Watson, Clark & Tellegen, 1988), severidad de síntomas somáticos (rS = .43) (SSS; Woolfolk & Allen, 2007) y alexitimia (rS = .41) (TAS20; Bagby, Parker & Taylor, 1994), e inversa y baja con afecto positivo (rS = -.18). Se concluye que el formato ahorra espacio y tiempo en su aplicación, además posee indicadores psicométricos buenos parecido a la escala original
