[The influence of life events and social support in a psycho-educational intervention for women with depression].
OBJECTIVE
To investigate the influence of social support and adverse life events on depression symptoms, before and after therapy (15-30 days) and during follow-up (4 months) of a psycho-educational intervention for depression.


METHODS
The study population consisted of 254 women with depression symptoms selected among those seeking treatment for their symptoms in three community mental health centers and in one Ministry of Health center, all of them in Mexico City, between January 1998 and December 2000. The intervention has been proved effective previously in reducing depression symptoms. Symptoms were assessed using Radloff's CES-D scale, while specifically designed scales were used for events and social support. Hierarchical regression analyses were carried out to test various models.


RESULTS
Model I: effect of variables: life events, social support, and socio-demographic variables (age, education level, income, and work status) on CES-D pre-treatment. The model was significant (p<0.000) and the first two variables and age were included in the model. Model 2: effect of the same predictive variables on CES-D post-treatment. The model was significant (p<0.001) and included social support and life events. Model 3: effect of the same variables on CES-D during follow-up. The model was significant (p<0.000) and included life events and educational achievement. Model 4: effect of social support and life events during follow-up on CES-D during follow-up. The model was also significant (p<0.000) and both variables were included in the model. Additional analyses for models 2 and 3 adding CES-D pre-treatment as a predictor showed that only the latter was significant.


CONCLUSIONS
Life events and social support are associated with initial depression symptoms and also predict the reduction of symptoms following the psycho-educational intervention. This may be due to the high correlation of life events and social support with CES-D pre-treatment. Life events and social support following the intervention also have an effect on CES-D in this same stage. The English version of this paper is available at: http://www.insp.mx/salud/index.html.
