Behavioral theory posits that certain environmental changes and avoidant behaviors inhibit individuals from experiencing environmental reward and reinforcement and subsequently leads to the development and maintenance of depressive symptoms.
The Beck Depression Inventory (BDI) is widely used to screen for depression and to measure behavioral manifestations and severity of depression. The BDI can be used for ages 13 to 80. The inventory contains 21 self-report items which individuals complete using multiple choice response formats.
Depression and Behavioral Disorders
According to the Cleveland Clinic, a behavioral disorder may trigger depression. The opposite is also possible, with depression being a trigger for a behavioral disorder, which can also lead to substance abuse.
Three fundamental types of behaviour can be distinguished: the purely practical, the theoretical-practical, and the purely theoretical.

Behavioural measures are those in which some other aspect of participants' behaviour is observed and recorded. This is an extremely broad category that includes the observation of people's behaviour both in highly structured laboratory tasks and in more natural settings.
A group of dogs would hear a bell ring and then they would be given food. After enough time, when the bell would ring the dogs would salivate, expecting the food before they even saw it. This is exactly what behaviorism argues—that the things we experience and our environment are the drivers of how we act.
Mental health problems in children and adolescents include several types of emotional and behavioural disorders, including disruptive, depression, anxiety and pervasive developmental (autism) disorders, characterized as either internalizing or externalizing problems.
Depression causes the hippocampus to raise its cortisol levels, impeding the development of neurons in your brain. The shrinkage of brain circuits is closely connected to the reduction of the affected part's function. While other cerebral areas shrink due to high levels of cortisol, the amygdala enlarges.
To be diagnosed with depression, an individual must have five depression symptoms every day, nearly all day, for at least 2 weeks. One of the symptoms must be a depressed mood or a loss of interest or pleasure in almost all activities. Children and adolescents may be irritable rather than sad.
