Stimulus Control Treatment (GAD)

An early behavioural intervention for worry in GAD which adopted the principle of stimulus control, based on the conditioning principle that the environments in which behaviours are enacted come to control their future occurrence and can act to elicit those behaviours.

Thought Suppression (OCD)

A defence mechanism used by individuals with obsessive thoughts to actively suppress them (using either thought suppression or distraction techniques).

Suffocation Alarm Theories (PD)

Models of panic disorder in which a combination of increased CO2 intake may activate an oversensitive suffocation alarm system and give rise to the intense terror and anxiety experienced during a panic attack.

Thought-Action Fusion (OCD)

A dysfunctional assumption held by OCD sufferers that having a thought about an action is like performing it.


Hair-Pulling Disorder in which the individual compulsively pulls out their own hair resulting in significant hair loss.

Specific Phobias

An excessive, unreasonable, persistent fear triggered by a specific object or situation.

Theory of Shattered Assumptions (PTSD)

A theory of PTSD that argues that a severe traumatic experience will shatter a person’s belief in the world as a safe and benign place, resulting in the symptoms typical of PTSD.
