Effectiveness of psychological treatments for depression in childhood and adolescence: A review of reviews

Depression in childhood and adolescence is a public health problem due to its high prevalence and the impact it has in the individual development. There is clear evidence of the efficacy of Interpersonal Therapy (IPT) and Cognitive-Behavioural Therapy (CBT) in the treatment of depression in children and adolescents; however, recent reviews and meta-analyses provide new perspectives for treatment. The purpose of this work is to synthesize the bibliography available through a systematic review of systematic reviews and meta-analysis that summarizes in a comprehensive way the evidence of the last two decades on the effectiveness of psychological interventions for infant-juvenile depression. A systematic review of systematic reviews and meta-analyses was performed. A search was conducted in the Web of Science and Scopus databases. Eight records met the inclusion criteria, 2 were analysed in their entirety and from the remaining 6 the information needed for independent analysis was extracted. Seven different psychotherapies were studied: CBT and IPT were the most studied (n=7; 87.5%), followed by family therapy (n=5; 62.5%), psychodynamic therapy (n=3; 37.5%), behavioural therapy (n=3; 37.5%), computerised CBT (n=2; 25%), problem-solving therapy (n=1; 12.5%) and supportive therapy (n=1; 12.5%). IPT and CBT were shown to be effective in the treatment of adolescent depression. Half of the reviews (n=4; 50%) had a low methodological quality and the other half (n=4; 50%) were classified as critically low. In general, psychological interventions for child and adolescent depression produce significant, but modest effects. Specifically, IPT and CBT can be considered the main treatment alternatives for adolescent depression. There is insufficient data of specific psychological treatment for children diagnosed with a depressive disorder. It is suggested that research should be increased to improve the methodological quality and increase the number of studies aimed at the children population.
