Rating Scales

The use of standardized rating scales at the initial assessment will provide a baseline against which to compare later assessments.

There are several different scales that you should be familiar with:

  • The Global Assessment of Functioning Scale (GAF), which is Axis IV of DSM-IV Diagnosis
  • The Social and Occupational Functioning Scale (SOFAS)
  • The Clinical Global Improvement Scale (CGI-1 and CGI-2)
  • The Role Functioning Scale
These scales are included in the early psychosis Care Pathway. To access these scales, click here.


To listen to Dr. Tom Ehmann give an overview of the GAF, SOFAS, CGI-1 and CGI-2 click here. Note: this is audio only; there is no accompanying video.You should have a printed copy of the GAF and CGI in front of you.

There are several other assessment tools that can provide important clinical information and help to engage the client and family.

  • Questions for Families – a list of questions for families about psychosis
  • 2-Com – a brief client self-report tool developed for schizophrenia but can be used with clients experiencing early psychosis

A collection of five checklists is available for clinicians: General Tips on Working with Cognition, Cognition and Attention, Cognition and Executive Functions, Cognition and Memory and Social Cognition.

Both of these scales are also included in the Care Pathway. To access these scales, as well as other Care Pathway tools, click here.


Do you know of any other asssessment tools or techniques designed to improve client or family collaboration in care? Post any ideas or suggestions on the group blog.

Activity Five: Thought Questions

The following thought questions are designed for you to think about how your own values and beliefs may impact your work with young people dealing with psychosis.

Considering your own interview style, what topics do you find challenging to ask during an assessment? What are the reasons that you find these topics challenging? Brainstorm ways that may help you be better prepared to address these topics in assessment.
