Brief Summary:

The importance of stress as a possible deteriorating factor for schizophrenic patients is well documented. However, this notion is based on subjective experience and retrospective psychological analysis.

A novel method of measuring cortisol using hair has a proven correlation to subjective stress in non-clinical as well as psychiatric clinical populations.

This pilot study will attempt to assess the use of cortisol hair level, as a marker of stress, to predict clinical deterioration in schizophrenic patients.
