Cognitive behavioral therapy has been shown to be effective in treating depression in children and adolescents (Lewinsohn and Clarke, 1999; Harrington et al, 1998, March et al., 2004). There is general consensus in the clinical literature that techniques from cognitive behavioral therapy approaches are likely to be effective in the treatment of depression (Brewin, 1996; Beech, 2000). In the Diagnostic and Statistical Manual of the American Psychiatric Association (APA, 2000), the symptoms of depression are: loss of interest or pleasure in activities; change in weight and appetite; changes in sleep habits; loss of energy; feeling worthless or guilty; suicidal thoughts; poor concentration and restlessness or slowing down. The classic model of depression, according to Beck (1979), focuses on the “cognitive depressive triad.” These negative thought patterns concern: First, the world, the past or current situation, for example, no one loves me. Second, I myself (self-criticism, guilt, blame), for example, am worthless. And thirdly, the future (despair, pessimism), for example, I will never succeed. The goals of CBT for depression generally include two main components. First, increase problem solving and active engagement; Second, restore patients' activity levels, particularly activities that bring them a sense of accomplishment as well as pleasure; and finally, help the patient to deny the negative cognitive biases in him and to develop a better and more balanced vision of the world, his situation, his future and himself (Ryan, 2003).

Relapse prevention methods focus on the consolidation and generalization of treatment gains over time. Some studies have proven that “age” could be considered important in determining treatment outcomes related to anxiety disorders in children. According to Barrett, Dadds, and Rapee (1996), young children tend to do better in family-involved treatments. Interestingly, Kendall et al (1997) and Weersing (2001) found that, in a sample of children aged seven to 15, younger children were more likely to respond favorably to treatment than older children. aged. These findings provide fundamental evidence that younger children may improve more quickly than older children and that they are also more likely to perform better in CBT than older children, particularly when treatment is focused on family..
