Behavioral activation is a technique from CBT that is often the initial step in treating depression. When we’re depressed, we can lack motivation and lose interest in activities we used to enjoy. As a result, we become much less active. And this decreased level of activity has a negative effect on our moods, and leaves us feeling even more depressed.
Behavioural activation involves gradually increasing our levels of activity. And as we become more active and start to do more, we begin to feel less depressed. And as we become less depressed, we regain our interest in things we used to like doing, which helps us become more active, and so on. So behavioral activation helps reverse vicious cycles that contribute to depression.
