Posttraumatic stress disorder is a mental illness that has gained a lot of press since the Vietnam War. Despite the press, however, many people do not realize what this condition is and how many lives it can and does impact.

Posttraumatic stress disorder is one of several anxiety disorders
. This particular condition is widely associated with military personnel who have seen live-action combat. It is, however, an equal opportunity offender and can sideline the lives of anyone who has undergone extreme trauma.

According to the National Institute of Mental Health, (NIMH), Post Traumatic Stress Disorder is one of the 5 recognized types of mental illness commonly known as anxiety disorders. While these five major categories are significant, the complexity of mental disorders demand for segmentation into even more conditions.

The biopsychosocial model proposes that biological, psychological, and social factors all play a role to varying degrees in causing depression. The diathesis–stress model posits that depression results when a preexisting vulnerability, or diathesis, is activated by stressful life events. The preexisting vulnerability can be either genetic, implying an interaction between nature and nurture, or the result of past experience such as learned views of the world formed in childhood. These interactive models to understanding the causes of depression have gained empirical support. For example, a prospective, longitudinal study uncovered a moderating effect of the serotonin transporter (5-HTT) gene on stressful life events in predicting depression. Specifically, depression may follow such events, but is more likely to in people with one or, even more so, two short alleles of the 5-HTT gene. A Swedish study estimated the heritability of depression (the degree to which individual differences in occurrence are associated with genetic differences) to be approximately 40% for women and 30% for men.

Behavioral Activation is a third generation behavior therapy for treating depression. It is one of many functional analytic psychotherapies which are based on a Skinnerian psychological model of behavior change, generally referred to as Applied Behavior Analysis. This area is also a part of what is called Clinical Behavior Analysis (CBA) and makes up one of the most effective practices in the professional practice of behavior analysis.
