Personal and societal costs are high when it comes to depression and these costs are one of the main motives for seeking out mental health consultation services. Treatment of depression through behavioural activation therapy has recently been the subject of encouraging studies. Two major studies confirmed that this treatment approach for depression has more sustainable effects and is less expensive than pharmacotherapy alone and is as effective as cognitive therapy (Dimidjian, et al., 2006; Dobson et al., 2008). What stands out in behavioural activation therapy resides in its capacity to alter the mood and depressive thoughts strictly through action; rather than putting emphasis on modifying the way of thinking, this therapy is centred on the progressive modification of behaviours associated with depression. With this approach, the therapist accompanies the client through the implementation of a list of potentially gratifying activities and of a concrete plan of action. They subsequently make a plan to overcome anticipated obstacles.  Clients are also encouraged to take note of the close relationship that links certain behaviours to their mood variations. This workshop is a unique opportunity to benefit from one of the world's leading experts on behavioural therapy as a treatment for depression. It is intended for psychotherapists who already have basic training in cognitive-behavioural therapy.
