Self and Interpersonal Functioning Scale (SIFS) Test

This brief self-report measure supports rapid screening of self and interpersonal functioning. The Self and Interpersonal Functioning Scale (SIFS) is designed to characterize the severity of difficulties relevant to personality functioning in clinical contexts.

It includes 24 items and typically takes about 5 minutes to complete. Items sample four broad domains: self-awareness, self-direction, empathy, and capacity for close, mutually supportive relationships.

In applied settings, the Self and Interpersonal Functioning Scale (SIFS) may be used to inform case formulation, support treatment planning, and monitor change over time, with results interpreted in conjunction with clinical interview and other assessment data.
