ABSTRACT
Background: According to the Chilean National Health Survey (2009-2010), 17% of people aged 15 years or more have depressive symptoms. Thus, freely-available, easily-administered, and highly sensitive screening tests for depression are needed in clinical and research settings. Aim: To evaluate the psychometric properties of a Spanish version of the Beck Depression Inventory (BDI-IA) in adult Chilean population. Material and Methods: The inventory was applied to a sample of 1.105 adults aged between 18 to 73 years (94% women). Ninety nine participants were outpatients receiving treatment for affective disorders, 932 were parents and/or guardians of students enrolled in schools and 73 were university students (sample with no known depressive disorder). To perform data analysis, two groups from the random combination of both samples were generated. Results: The inventory showed an appropriate degree of internal consistency (Cronbach alpha = .92). An exploratory factor analysis suggested a one-factor solution. This solution was reinforced with a confirmatory factor analysis, which displayed an adequate goodness of fit. The cutoff score, based on the Youden Index, was 13/14 points. It was able to discriminate between depressed and non-depressed participants. Conclusions: These results indicate that the BDI-IA is an appropriate instrument to assess depressive symptoms in Chilean adults.

La sintomatología depresiva es frecuente en el embarazo y repercute en el posparto y en el vínculo madre-bebé. Se reportan los resultados de una intervención grupal de 5 sesiones para reducir la sintomatología depresiva y promover una adecuada sensibilidad materna. Participaron 134 embarazadas con antecedentes de depresión (grupo experimental = 88 y grupo control = 46). Se evaluó sintomatología depresiva (Inventario para la Depresión de Beck), resolución de problemas sociales (Inventario de Resolución de Problemas Sociales Abreviado), sensibilidad materna, cooperatividad infantil y riesgo vincular (Índice Experimental de Relación Niño-Adulto) en ambos grupos. Se observó una reducción significativa de la sintomatología depresiva, así como un incremento de las habilidades para la resolución de problemas sociales en el grupo intervenido. Este grupo muestra también puntajes significativamente mayores en sensibilidad materna y cooperatividad infantil, así como menores frecuencias de riesgo vincular en la evaluación postintervención. Se discute la relevancia de desarrollar estrategias de intervención durante el embarazo, considerando su impacto en la sensibilidad materna, en la calidad de las interacciones madre-bebé y en las habilidades de las madres para resolver problemas.
Depressive symptoms are frequently observed during pregnancy, and these affect the mother and her relationship with her baby during the post-partum period. Results are reported on a 5-session group intervention for reducing depressive symptoms and promoting maternal sensitivity. The participants included 134 pregnant women with a history of depression (experimental group = 46 and control group = 88). Depressive symptoms (Beck Depression Inventory), social problem-solving strategies (Social Problem-Solving Inventory-Revised), maternal sensitivity, infant cooperativeness and bonding risk (Child-Adult Relatinoship Experimental Index) were assessed in both groups. The group intervened showed a significant reduction of depressive symptoms and an improvement of social problem-solving strategies. This group also shows significantly higher scores in maternal sensitivity, and infant cooperativeness, as well as lower frequencies of bonding risk in the post-intervention assessment. The importance of considering intervention strategies during pregnancy, including its impact on maternal sensitivity, the quality of mother-baby interactions and the problem-solving abilities of the mothers, is discussed.
