This study evaluates the efficacy and acceptability of two cognitive-behavioural interventions for reassurance seeking behaviour in obsessive-compulsive disorder (OCD), a family accommodation reduction protocol vs. a novel support-seeking protocol. Half of participants will be randomly assigned to participate in the support-seeking intervention, whereas the other half will participate in the family accommodation reduction intervention.
An existing family accommodation reduction intervention to reduce reassurance seeking behaviour in OCD (which represents treatment as usual, or TAU) is being compared to a novel support-seeking intervention to determine which is more efficacious and acceptable to participants.
The TAU protocol asks participants to make an agreement with their significant others to withhold reassurance when it is sought. It is believed that this behaviourally-based intervention encourages extinction of reassurance seeking over time by eliminating reinforcement of the behaviour by significant others.
The support-seeking intervention asks participants to move towards adaptively seeking support from a significant other to manage anxiety or distress rather than seeking reassurance. Significant others are taught to provide support rather than reassurance. It is believed that support-seeking may reduce reassurance seeking behaviour because it helps participants manage the anxiety or distress that underlies the requests for reassurance without interfering with disconfirmatory learning.
