Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The treatment includes eight two hour sessions over eight weeks and will be conducted in a group format. Two therapists will be present at each session. A treatment manual will be adapted for Worry treatment based on the Behavioural Activation handbook, Overcoming Depression one step at a time (Addis, M & Martell, C., 2004). The primary focus of Behavioural Activation (BA) treatment is in the use of functional analysis to provide individuals with psychosocial education to differentiate between helpful or unhelpful thinking. Individuals are then coached to shift towards more adaptive thinking styles. BA starts in functional analysis focusing on assessment and treatment of avoidance behaviours- variability of (1) Worry (e.g., differences between helpful and unhelpful thinking about problems); (2) Associated behaviours and (3) Counter-worry behaviours such as effective engagement in tasks. This detailed analysis of context and function is then used to help clients: (1) Recognize warning signs for worry; (2) Develop alternative strategies and contingency plans; some helpful alternative behaviour include allowing worry to cue the clients to take action, attending to their experience, etc.; (3) Alter environmental and behavioural contingencies maintaining worry.
