It’s an obvious statement to say that the current status of our political scene is heated, to say the least. In my practice, I see young children (ages 4-6) all the way through age 17 (and adults). I have found it very concerning how recently my kids have expressed worries, anxiety, and sadness not on the candidate of choice, but rather on overhearing dismal phrases of the future adults have reported. One of three basic models of anxiety and depression is based on observational learning (others are classical and operant conditioning, along with basic biology). When kids watch adults express their opinion or react a certain way, there can be a very high tendency to model/copy those phrases and behaviors. Think about the Bobo doll example (i.e., a child watches an adult hit a Bobo doll, a child enters the room alone, the child then hits the Bobo doll). If your child is hearing you, other adults, or teachers around them speak about the status of their future, your worries can become theirs, your sadness can become theirs. This process can happen quite automatically, without awareness or mal intent. At some point, kids integrate these worries as their own, and these worries can manifest themselves as clinical anxiety or depression.
As a clinical psychologist it is not my job to remark on the political scene. It is my job, however, to work to actively prevent the occurrence and recurrence of mental illness in children. Regardless of what your political stance is, try and keep in mind that you, as an adult are very influential on a child and they can model their thoughts, opinions, and concerns on yours.
