Predicting therapy outcome in patients with early and late obsessive-compulsive disorder (EOCD and LOCD).

BACKGROUND

Increasing attention has been given to subtyping OCD with respect to different clinical profiles, response to drug treatments, comorbidity and age of onset. There are a number of studies looking at predictors of treatment outcome in OCD, but so far not for OCD subtypes.

METHOD

Prediction of outcome after cognitive-behavioural therapy was evaluated in 63 inpatients with early obsessive-compulsive disorder (EOCD < or = 12 years of age) and 191 patients with late obsessive-compulsive disorder (LOCD > 15 years of age).

RESULTS

For EOCD patients factors predicting a good outcome included high motivation and high initial Y-BOCS scores. Factors associated with a bad outcome were higher age at assessment, a longer duration of psychiatric inpatient treatment before assessment and a low level of social functioning (BSS). For LOCD patients living in a stable relationship, high motivation and completing treatment predicted a favourable therapy outcome, while a low level of psychological functioning (BSS) and a longer duration of inpatient psychiatric treatment before assessment were associated with an undesirable therapy outcome.

CONCLUSIONS

Subtyping OCD patients according to age of onset seems to be a promising avenue towards improving and developing more specified treatment programs.
