Behavioural Activation as a Transdiagnostic Treatment Approach


Behavioural activation (BA), in some form, has been used by cognitive-behaviour therapists for decades.  Although activity diaries and pleasant events scheduling have a long history, BA as a full treatment that targets avoidance behaviour and ruminative thinking patterns has a more recent history.  Research has demonstrated efficacy of BA used with depressed clients, in PTSD treatment, and with clients living with co-occurring mental health problems and physical illnesses.

This workshop will look at BA as a treatment approach that has transdiagnostic value.  Helping clients to re-engage in their lives, approach rather than avoid distressing feelings and events, and actively solve problems rather than brood about them are strategies addressing common maintaining factors in a variety of psychological disorders.  This workshop is geared to clinicians who have experience with CBT, and is intended to focus on both theoretical and practical implications.
