Child psychotherapy

Child psychotherapy, or mental health interventions for children have developed varied approaches over the last century. Two distinct historic pathways can be identified for present-day provision in Western Europe and in the United States: one through the Child Guidance Movement, the other stemming from Adult psychiatry or Psychological Medicine, which evolved a separate Child psychiatry specialism. 
Terms describing child-focused treatments may vary from one part of the world to another, with particular differences in the use of such terms, as "therapy", "child psychotherapy" or "child analysis".
Psychoanalytic Child Psychotherapy.
Psychoanalytic psychotherapy with infants, children and adolescents is mainly delivered by people qualified specifically in psychoanalytic child psychotherapy, or by trainees under supervision from a specialist in child-focused treatment. Recent evidence, covering 34 research papers (nine of which were randomized controlled trials) showed psychoanalytic psychotherapy to be particularly effective for children with the following conditions:
Furthermore, follow-up research shows that in psychoanalytic psychotherapy, therapeutic improvements continue well beyond the termination of the therapy itself. This has been termed a, "sleeper effect."
In the UK, psychoanalytic psychotherapy is recommended by NICE as an evidence-based treatment for trauma from sexual abuse and severe depression in adolescents following the IMPACT study
Evidence-based Child and adolescent psychiatry.
There are various therapeutic assessments to address mental health concerns among children and adolescents. Some approaches are backed by strong scientific evidence, while some are not. Some research suggests that it is the quality of the relationship with the therapist, rather than the particular form of therapeutic intervention, that is the strongest factor in helping change develop.
Parent–infant psychotherapy.
If the normal course of secure attachment between parent and infant is disrupted, parent–infant psychotherapy is a catch-all term to describe psychotherapies that either aim to restore this bond or to work with vulnerable parents to overcome disruption and prevent further occurrence. Examples of this kind of therapy include, "Watch, Wait, Wonder," and psychoanalytic parent-infant psychotherapy. Many of these techniques require a three-way relationship between the parent, child, and therapist. During therapy sessions, the parent may express his or her thoughts and feelings which are based on a combination of factors including:
The therapist's role is as an observer and an interpreter of the interaction between the infant and the parent. He might share some of his thoughts about the behavior of the child with the parent and by doing so offering the parent an alternative way of experiencing the child. This technique helps the parent to resolve issues with his or her own infancy-experiences in order to restore secure attachment with the infant. And it helps lower the risk for psychopathological developments of the child in the future.
