Can parenting support and education help patients with anxiety and depression?

I recently had a GP Trainee sitting in on one of our “parenting training” consultation to assist mum and her primary school age son.  

Both mum and her son suffer significantly in the mental health space. 

Our Trainee was surprised to know that “parenting training” is an approved evidence based method and focused psychological strategy to assist patients with managing their mental health disorders like depression and anxiety.  

I suspect that many other Trainees/Medical Students would be surprised too.
