Background With regard to long-term outcome, behaviour therapy is the
first choice treatment for obsessive-compulsive disorder (OCD), with o
r without concomitant selective serotonin reuptake inhibitor (SSRI) me
dication. Yet, results from research trials, usually restricted to exp
osure with response-preventions and other symptom-directed techniques,
may not be generalisable to people with OCD in community health care
services. Method For more than 20 years we have delivered out-patient
behaviour therapy to unselected people with OCD from the community, in
cluding those with motivational and compliance problems. Prospective-r
etrospective follow-ups were carried out from 1-13 years after treatme
nt. Results This paper describes the applied multi-modal, strategic-sy
stemic behaviour therapy, and our partially new model of OCD. Complian
t patients achieved the usual success rate of 65-70%, but-this drops t
o 50% if all patients treated are included in the analysis. Conclusion
s For major subgroups of OCD, behaviour therapy is a very effective tr
eatment modality. Exposure is essential, but additional ('causal') int
erventions are equally important in about half of the patients from un
selected samples. Both behaviour therapy and drug-treatments need to b
e improved and predictive variables for outcome of either of them are
urgently needed.
