Schwartz Outcome Scale (SOS) Measuring psychotherapy outcomes

The Schwartz Outcome Scale (SOS) has the potential to be a useful measure of counseling outcomes.


I and my colleagues used the 10-item version of the Schwartz Outcome Scale in two recent studies about psychotherapy patients. The scale measures several aspects of well-being: physical, relational, and psychological functioning and the person’s capacity to be peaceful, interested, excited, and satisfaction with life.


In our two studies, coefficient alpha reliability values were .93 and .96 (Sutton et al., 2018).


In previous research, the SOS was linked to hope, self-esteem, affect, mental health, and life satisfaction  (Young, Waehler, Laux, McDaniel, & Hilsenroth, 2003).

Some validity findings based on positive correlations with other measures may be of interest to clinicians and researchers (Sutton et al. (2018).

   Satisfaction with counseling .63

   Likely to return to counseling .56

   Spiritual well-being .84

   Big 5 measures of 
Extraversion (.47) and 
Neuroticism (emotional stability) .40.
