The IFS SCALE provides a profile of personality using the conceptual framework of the Internal Family Systems ModelSM.
This is a 57-item self-report measure (a = .98; item-to-total correlations: .44 to .85), intended for use with adults. The individual is asked, on a 5-point Likert scale, how frequently he or she experiences various thoughts and feelings.
The scale is designed to provide the following information:
-What types of parts are dominating the internal system?
-How extreme are the parts?
-How much access to Self-leadership is there at present?
-What types of Managers are protecting the system?
-Are there any potentially dangerous Firefighters, such as self-harming parts, in this system?
-How much progress have we made? (When it is used as a pre-test/post-test assessment.)
Purpose: To assess the intrapsychic system within the framework of the IFS (Internal Family Systems) modelSM.
For: Ages 18 and older
Time: 15 minutes
Internal consistency (Cronbach’s alpha): a = .98
Item-to-total correlations: .44 to .85
This scale discriminated between high- and low-trauma groups, p < .000, consistent with IFS theory.
