Measurement based care (MBC) in psychiatry is well established as an approach to monitor change in symptom burden and optimize
outcomes. In mood and anxiety disorders, both clinician-rated scales and self-report measures are valid, reliable, easy to use, and
simple to implement for community dwelling outpatients. In schizophrenia, however, anosognosia or poor insight, and inaccurate
symptom reporting, undermine the utility of self-reported measures. Clinician-rating scales such as the Positive and Negative Symptom
Scale (PANSS) and the Brief Psychiatric Rating Scale (BPRS) are valid and reliable, but slightly more time consuming than their mood
and anxiety disorder equivalents, require more intensive rater training, and thus are less likely to be used in routine practice. Newer
schizophrenia guidelines and changing treatment paradigms are moving beyond the unidimensional approach to treating only symptoms
in schizophrenia. Relapse prevention and functional recovery are now important 21st century outcomes, and are more consistent with
patient-reported goals for treatment of their illness. Moreover, functional status may be more reliably reported than positive psychotic
symptoms, and can be an area of focus for the development of meaningful outcome measures for those with psychotic disorders.
We present here the development of a self-report rating scale in schizophrenia for functional outcomes. Important component domains
include productivity, self-care, leisure, and quality of life, all of which are important to patients, and are related to medication adherence
and efficacy. We also present the validation protocol, to be implemented in partner sites across Canada.
