Premorbid adjustment, symptom development and quality of life in first episode psychosis: a systematic review and critical reappraisal.
OBJECTIVE
To systematically review the relationship of premorbid adjustment to symptomatology in first episode psychosis (FEP), taking into account the influence of duration of untreated psychosis (DUP).


METHODS
Electronic databases were searched to identify relevant studies.


RESULTS
A variety of approaches to the reporting of premorbid adjustment were identified. There was no significant association between premorbid adjustment and DUP, supporting the proposition that they are independent constructs. The effect of premorbid adjustment upon positive symptomatology was negligible. Premorbid adjustment had a modest effect upon negative symptoms and quality of life, increasing over duration of follow-up.


CONCLUSIONS
Premorbid adjustment remains a valid construct in the study of FEP. Both premorbid adjustment and DUP confer independent effects on aspects of symptomatology in FEP. Results for premorbid adjustment are similar to previous findings in more chronic samples. The potential for conceptualizing premorbid functioning by developmental, academic/social and typological approaches is currently underexploited.
